Empirically determined data relating the influence of secondary operating parameters of volumetric bulk material transport rate of the solid plant matter, type of the solid plant matter, and physicochemical characteristics and properties of the solid plant matter, on the sensing and measuring of the primary forced-air operating parameters are used for process correcting raw temperature, humidity, and flow rate, parametric values of the forced-air entering and existing the solid plant matter, leading to the determination of highly accurate and reproducible values of moisture content and uniformity of the solid plant matter. Moisture content and uniformity values correspond to the volume of the solid plant matter.

Description: METHOD AND DEVICE FOR NON-INVASIVELY DETERMINING MOISTURE CONTENT AND UNIFORMITY OF SOLID PLANT MATTER DURING ON-LINE DRYING OR COOLING FORCED-AIR TREATMENT FIELD AND BACKGROUND OF THE INVENTION The present invention relates to determining moisture content and uniformity of solid plant matter, and more particularly, to a method for non-invasively determining moisture content and uniformity of solid plant matter during on-line drying or cooling forced-air treatment, based on measuring temperature, humidity, and flow rate of the forced-air passing through the volume of the solid plant matter. A wide variety of raw materials used for manufacturing food, pharmaceutical, and tobacco products are obtained from solid plant matter. Hereinafter, the term 'solid plant matter' refers to any essentially solid part or component of a plant, including, but not limited to, leaves, beans, seeds, grains, flowers, stems, stalks, and roots, in raw or processed, loose or web, form. For example, tea leaves, coffee beans, and tobacco leaves are used for manufacturing tea, coffee, and tobacco products, respectively. From the site of cultivation, raw solid plant matter is harvested, bundled or packaged, transported, and stored in a variety of forms before being used in manufacturing processes. Subsequent food, pharmaceutical, and tobacco product manufacturing processes are performed in stages involving a variety of procedures, from initial processing of loose raw solid plant matter leading to using the initially processed solid plant matter for producing bulk quantities of various consumer end products. These end products are subsequently sub-divided, packaged, stored, and transported throughout the consumer marketplace according to distribution, marketing, and selling criteria. The present invention focuses on that stage of the manufacturing sequence involving in-house treatment of initially processed raw solid plant matter. In particular, the stage involving drying or cooling of wetted raw solid plant matter by subjecting it to an on-line forced-air treatment. As part of an overall manufacturing sequence, some types of raw solid plant matter are intentionally and controllably wetted, for example, by subjecting them to steam, for the purpose of enhancing particular physicochemical properties of the raw solid plant matter needed for entry into further downstream processes. For example, raw tobacco leaves are wetted for causing opening of pores of the leaves, resulting in enhancing particular physicochemical properties of the tobacco leaves essential to characteristics and performance of tobacco end products. In such a manufacturing sequence, wetted raw solid plant matter exiting a wetting apparatus is transported by an on-line conveyor passing through a drying or cooling apparatus, such as a multiple open sided chamber, featuring an inlet and outlet through which forced-air passes, thereby drying or cooling the wetted solid plant matter. During the drying or cooling forced-air treatment, moisture content, and consequently, uniformity, throughout the volume of the initially wetted solid plant matter change, according to the operating parameters of the forced-air treatment. At this stage of such a manufacturing sequence, moisture content and uniformity are important properties of the solid plant matter which need to be determined, monitored, and controlled prior to the solid plant matter entering further downstream processes or storage. In particular, if the moisture content and/or uniformity of a given wetted solid plant matter raw material are outside of established quality control values, use of such solid plant matter is expected to lead to downstream intermediate products, or stored solid plant matter, similarly failing their established quality control values, potentially causing undesirable rejection of material, manufacturing down time and added cost. Recently, several methods and devices, based on microwave technology, have been disclosed for on-line non-invasively measuring and calculating moisture content of materials, including plant derived materials such as cotton, tea leaves, and tobacco leaves. Disclosures include U.S. Patent Application Nos. 09/143,966; 09/126,384; 08/974,983, and 08/777,872. In these disclosures, typically, a radiation source beam is transmitted through a portion of material and is received by a receiving antenna, which then produces a signal. Microwave signal parameters such as attenuation and phase shift are used to measure and determine moisture content, density, and uniformity of the material. The disclosed methods and devices are primarily applicable to bulk quantities of loose or packaged materials, such as bales, being transported on-line through a silo or being transported between bulk material storage facilities, and include no description relating to measuring or determining moisture content of the material during a drying or cooling process. In U.S. Patent No. 5,870,926, there is teaching of applying infrared spectroscopy for non-invasively determining moisture content of solid plant matter during an on-line drying or cooling treatment. In this disclosure, exposed surface area of solid plant matter passing through a drying or cooling apparatus is subjected to an infrared beam, whose output is compared to the output of a reference or calibration beam, for obtaining on-line values of infrared reflections proportional to moisture content of the solid plant matter exiting the drying or cooling apparatus. In practice, the disclosed method and device are significantly limited by interference during the infrared measurements, caused by the presence of varying quantities of dirt on the surface of the infrared source and receiver apparatus, and dust in the surrounding air. This disclosure is additionally limited by the infrared measurements providing information relating only to the exposed surface area of the solid plant matter during on-line transport, and is not capable of providing moisture content or uniformity information relating to the volume of the moving solid plant matter. Even for low density loose solid plant matter, results of moisture content or uniformity obtained by related methods and devices are significantly limited. Aside from radiation based methods and devices, currently available methods and devices for non-invasively determining moisture content, and consequently, uniformity, of wetted solid plant matter passing through an on-line drying or cooling forced-air treatment are typically based on only measuring the humidity of the forced-air passing through the drying or cooling device. Here, for a given temperature, the difference in humidity of the forced-air entering and exiting the drying or cooling apparatus is proportional to moisture content, and consequently, uniformity, of the solid plant matter exiting the drying or cooling apparatus. Actually, in an on-line drying or cooling forced-air treatment of wetted solid plant matter, measurement of several operating parameters, in addition to humidity of the forced-air, is required for accurately and reliably determining moisture content and uniformity of the continuously moving solid plant matter. Primary operating parameters most affecting moisture content and uniformity of the moving solid plant matter are the temperature, humidity, and flow rate of the forced-air used for drying or cooling the wetted solid plant matter as it passes through a drying or cooling apparatus. Secondary operating parameters affecting moisture content and uniformity of the moving solid plant matter include (1) the volumetric bulk material transport rate of the solid plant matter transported by an on-line conveyor through the drying or cooling apparatus during the drying or cooling forced-air treatment, where this operating parameter is a function of the configuration or volume of the bulk solid plant matter fed onto, and situated on, the on-line conveyor, and a function of the linear speed or velocity of the on-line conveyor, (2) the type of solid plant matter, as described above, and (3) physicochemical characteristics and properties, such as density, of the solid plant matter subjected to the on-line drying or cooling forced-air treatment. To one of ordinary skill in the art, there is thus a need for, and it would be useful to have a method and device for non-invasively determining moisture content and uniformity of solid plant matter during on-line drying or cooling forced-air treatment, based on measuring temperature, humidity, and flow rate of the forced-air passing through the volume of the solid plant matter. Moreover, accurate and precise determination of moisture content and uniformity of solid plant matter during forced-air treatment would enable optimization and control of the drying or cooling forced-air treatment, thereby contributing to optimization and control of an overall manufacturing sequence for producing consumer end products containing solid plant matter raw materials. SUMMARY OF THE INVENTION The present invention relates to a method and device for non-invasively determining moisture content and uniformity of solid plant matter during on-line drying or cooling forced-air treatment, based on measuring multiple operating parameters including temperature, humidity, and flow rate of the forced-air passing through the volume of the moving solid plant matter.

Moisture content and uniformity values thus obtained correspond to the volume of the moving solid plant matter, and are not limited to the exposed surface of the moving solid plant matter, as taught in the prior art. It is to be understood that the invention is not limited in its application to the details of construction, arrangement, and composition of the components set forth in the following description and accompanying drawing. The following description refers to an exemplary device used in a drying or cooling forced-air treatment of solid plant matter, in order to illustrate implementation of the present invention. The invention is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. Components and operation of the preferred embodiment of the device used for implementing the method of the present invention are herein described. Steps and sub-steps of the preferred embodiment of the method for non-invasively deterrnining moisture content and uniformity of solid plant matter during on-line drying or cooling forced-air treatment, according to the present invention are described thereafter. Referring now to the drawings, FIG. 1 illustrates an exemplary preferred embodiment of the device for implementing the method of the present invention. Device 10 is designed for subjecting solid plant matter 50 to the on-line drying or cooling forced-air treatment. Device 10 features (i) a solid plant matter inlet 12, (ii) a solid plant matter outlet 14, and (iii) a solid plant matter transport mechanism 16, such as a conveyor, for on-line automatically and controllably, continuously or discontinuously, transporting solid plant matter 50 into and out of the device. Device 10 also features (iv) a forced-air inlet unit 18, (v) a forced-air outlet unit 20, and (vi) a forced-air supply mechanism 22 for on-line automatically and controllably, continuously or discontinuously, forcing an air supply into and out of device 10 and the volume of solid plant matter 50. In a typical manufacturing scenario, steamed or wetted solid plant matter 50 leaves a steaming, wetting, or humidifying apparatus 60 and enters solid plant matter inlet 12 of device 10 for drying or cooling forced-air treatment. The volumetric bulk material transport rate of the solid plant matter transported by an on-line conveyor through the drying or cooling apparatus during the drying or cooling forced-air treatment is set according to the configuration or volume of the bulk solid plant matter fed onto, and situated on, solid plant matter transport mechanism 16, such as an on-line conveyor, and of the linear speed or velocity of sold plant matter transport mechanism 16. Forced-air inlet unit 18 features a single forced-air inlet element 24, or features a plurality of forced-air inlet elements 24, for guiding the forced-air into solid plant matter 50. Similarly, forced-air outlet unit 20 features a single forced-air outlet element 26, or features a plurality of forced-air outlet elements 26, for guiding the forced-air out of solid plant matter 50. Forced-air inlet unit 18 and force-air outlet unit 20 may each be fixed in place in device 10, or may each be mobile for movement through device 10. Moreover, any number of forced-air inlet elements 24 and/or any number of forced-air outlet elements 26 may be fixed in place in device 10, or may be mobile for movement through device 10. Forced-air supply mechanism 22 is capable of supplying forced-air having conditions of laminar or turbulent flow, to the moving solid plant matter 50, for example, by varying operating parameters or properties of the forced-air, such as temperature, pressure, volumetric flow rate, density, and viscosity. In particular, the speed by which the method of the present invention determines moisture content and uniformity of solid plant matter 50 is, in part, influenced by the operating parameters and flow characteristics of the forced-air passing through solid plant matter 50, such as whether the forced-air flow is laminar or turbulent. Device 10 also features (vii) at least one set 28 of, preferably, but not limited to, three, inlet forced-air parametric sensors 32, 34, and 36, and (viii) at least one set 30 of, preferably, but not limited to, three, outlet forced-air parametric sensors 38, 40, and 42, for enabling sensing and measuring operating parameters of the forced-air entering and exiting, respectively, solid plant matter 50 moving through device 10. Preferably, device 10 features a plurality of identical sets 28 of inlet forced-air parametric sensors 32, 34, and 36, and a plurality of identical sets 30 of outlet forced-air parametric sensors 38, 40, and 42. Any number of the at least one set 28 of inlet forced-air parametric sensors and/or any number of the at least one set 30 of outlet forced-air parametric sensors may be fixed in place in device 10, or may be mobile for movement through device 10. Moreover, any number of inlet forced-air parametric sensors 32, 34, and 36, and/or any number of outlet forced-air parametric sensors 38, 40, and 42, may be fixed in place in device 10, or may be mobile for movement through device 10. In this particular embodiment of the method, primary operating parameters of the forced-air entering and exiting the solid plant matter, to be sensed and measured, are temperature, T(air), humidity, H(air), and flow rate, FR(air). In principle, any number of other operating parameters or properties of the forced-air used for drying or cooling the solid plant matter, which can be sensed and measured, can be included in each of the sets 28 and 30 of inlet and outlet forced-air parametric sensors. The forced-air parametric sensors are devices, mechanisms, or components, preferably of electro-mechanical design and operation, enabling on-line automatic and controllable, continuous or discontinuous, sensing and measuring the forced-air operating parameters of temperature, humidity, and flow rate, as the forced-air enters and exits the moving solid plant matter 50. Accordingly, each set 28 of inlet forced-air parametric sensors includes (1) an inlet forced-air temperature sensor 32, for sensing and measuring the inlet forced-air temperature, Tι n (air), (2) an inlet forced-air humidity sensor 34, for sensing and measuring the inlet forced-air humidity, Hj n (air), and (3) an inlet forced-air flow rate sensor 36, for sensing and measuring the inlet forced-air flow rate, FR; n (air). Each set 30 of outlet air parametric sensors includes (1) an outlet forced-air temperature sensor 38, for sensing and measuring the outlet forced-air temperature, T out (air), (2) an outlet forced-air humidity sensor 40, for sensing and measuring the outlet forced-air humidity, H out (air), and (3) an outlet forced-air flow rate sensor 42, for sensing and measuring the outlet forced-air flow rate, FR out (air). According to actual design and resulting geometrical and spatial configuration, of device 10 and device components used for drying or cooling forced-air treatment of solid plant matter 50, there are different particular ways of device 10 featuring the at least one set 28 of inlet forced-air parametric sensors, and the at least one set 30 of outlet forced-air parametric sensors. Specifically, according to electro-mechanical design, and resulting geometrical and spatial positioning and alignment, of forced-air inlet unit 18, forced-air inlet elements 24, and inlet forced-air parametric sensors 32, 34, and 36, relative to forced-air outlet unit 20, forced-air outlet elements 26, and outlet forced-air parametric sensors 38, 40, and 42. Preferably, forced-air inlet unit 18 and forced-air outlet unit 20 are electro-mechanically configured such that, each forced-air inlet element 24 is associated, and axially aligned, with a localized set 28 of inlet forced-air parametric sensors 32, 34, and 36, and, each forced-air outlet element 26 is associated, and axially aligned, with a localized set 30 of outlet forced-air parametric sensors 38, 40, and 42. More preferably, each association, where an exemplary single inlet association is referenced as 52, of forced-air inlet element 24 and localized set 28 of inlet forced-air parametric sensors is electro-mechanically paired, and axially aligned, with a corresponding association, where an exemplary single outlet association is referenced as 54, of forced-air outlet element 26 and localized set 30 of outlet forced-air parametric sensors. This type of electro-mechanical configuration enables obtaining and spatially pairing a set of sensed and measured inlet forced-air parameters with a corresponding set of sensed and measured outlet forced-air parameters, in the same local vicinity of the forced-air entering and exiting, respectively, solid plant matter 50 moving through device 10. Device 10 further features (ix) a central processing unit 44, and (x) a plurality of control/data links (shown without reference numbers) among device components. Central processing unit 44 is for automatically and controllably operating device 10 and device components. This includes sending control/data signals to device components, receiving data signals from device components, and, processing and storing data signals and data received from device components. In particular, this includes operating solid plant matter transport mechanism 16, for example, by controlling the quantity, in terms of mass, volume, or density, and/or rate of solid plant matter 50 passing through device 10, such as by controlling a conveyor linear speed or velocity. This also includes operating forced-air inlet unit 18 and forced-air outlet unit 20, and forced-air supply mechanism 22, for example, by controlling the quantity, rate, and/or parameters, of the forced-air passing through solid plant matter 50, such as by opening or closing selected forced-air inlet elements 24 and/or forced-air outlet elements 26, and controlling, for example, temperature, pressure, humidity, and/or flow rate of the forced-air supplied by forced-air supply mechanism 22. Central processing unit 44 also enables determining values of moisture content and uniformity of the solid plant matter, by converting, storing, processing, and performing calculations on, data received from inlet sets 28 and outlet sets 30 of forced-air parametric sensors 32, 34, and 36, and, 38, 40, and 42, respectively, during the forced-air treatment. Central processing unit 44 is also used for obtaining, processing, and storing calibration and process related empirical data. Calibration and process related empirical data features, for example, determinations of moisture content and uniformity made during conditions involving well characterized and controlled primary operating parameters of forced-air temperature, humidity, and flow rate, and, well characterized and controlled secondary operating parameters of (1) the volumetric bulk transport rate of solid plant matter 50 transported by solid plant matter transport mechanism 16, such as a conveyor, through drying or cooling device 10 during the on-line drying or cooling forced-air treatment, where this operating parameter is a function of the configuration or volume of the bulk solid plant matter 50 fed onto, and situated on, solid plant matter transport mechanism 16, and a function of the linear speed or velocity of solid plant matter transport mechanism 16, (2) the type of solid plant matter 50, and (3) physicochemical characteristics and properties, including known moisture content and uniformity, of solid plant matter 50 subjected to the drying or cooling forced-air treatment. Calibration and process related empirical data are used for process correcting raw inlet and outlet forced-air parametric values. Process corrected inlet and outlet forced-air parametric values are subsequently used for determining values of moisture content and uniformity of solid plant matter 50. The plurality of control/data links (shown without reference numbers) is for enabling on-line automatic and controllable, continuous or discontinuous, electronic communication between each component of device 10 and central processing unit 44. Steps and sub-steps of the preferred embodiment of the method for non-invasively determining moisture content and uniformity of solid plant matter during on-line drying or cooling forced-air treatment, according to the present invention are herein described, with reference to FIG. 1. In Step 1, there is sensing and measuring (i) the at least one set of inlet forced-air operating parameters by the at least one set 28 of inlet forced-air parametric sensors 32, 34, and 36, for generating at least one corresponding set of inlet forced-air parametric sensor electrical signals, and, sensing and measuring (ii) the at least one set of outlet forced-air operating parameters by the at least one set 30 of outlet forced-air parametric sensors 38, 40, and 42, for generating at least one corresponding set of outlet forced-air parametric sensor electrical signals, while the forced-air continuously or discontinuously enters and exits device 10 and the volume of solid plant matter 50, and, while solid plant matter 50 continuously or discontinuously enters and exits device 10. Preferably, there is simultaneously sensing and measuring each inlet forced-air operating parameter of each set of inlet forced-air operating parameters simultaneously to sensing and measuring each outlet forced-air operating parameter of each paired set of outlet forced-air operating parameters, by electro-mechanically paired and axially aligned sets 28 and 30 of inlet and outlet forced-air parametric sensors, respectively, according to operation of the electro-mechanically paired and axially aligned forced-air inlet and outlet elements 24 and 26, respectively, as described above and illustrated by 52 and 54. Each forced-air parametric sensor 32 - 42 senses and measures one of the forced-air operating parameters, T(air), H(air), or FR(air), whereby each forced-air parameter affects an electro-mechanical mechanism of the respective forced-air parametric sensor 32 - 42, for generating an electrical output signal, such as a voltage or current output signal, where the magnitude of the electrical output signal is functionally proportional to the magnitude of the respective forced-air operating parameter. Accordingly, each set of inlet forced-air parametric sensor electrical signals includes (1) an inlet forced-air temperature sensor electrical signal, (sχ)in, (2) an inlet forced-air humidity sensor electrical signal, (s H )i n , and (3) an inlet forced-air flow rate sensor electrical signal, (spi in- Each set of outlet forced-air parametric sensor electrical signals includes (1) an outlet forced-air temperature sensor electrical signal, (sχ) ou t, (2) an outlet forced-air humidity sensor electrical signal, (s^ out , and (3) an outlet forced-air flow rate sensor electrical signal, (spr o ut- Step 1 preferably includes sending (i) each of the at least one set of inlet forced-air parametric sensor electrical signals, and (ii) each of the at least one set of outlet forced-air parametric sensor electrical signals, to central processing unit 44. Preferably, there is simultaneously sending each set of the inlet forced-air parametric sensor electrical signals simultaneously to sending a paired set of the outlet forced-air parametric electrical signals, to central processing unit 44, according to operation of the electro-mechanically paired and axially aligned inlet and outlet forced-air elements 24 and 26, and corresponding sets 28 and 30 of inlet and forced-air outlet parametric sensors 32 - 42, respectively, as described above and illustratively shown by 52 and 54. In Step 2, there is also converting (i) each inlet forced-air parametric sensor electrical signal of each of the at least one set of the inlet forced-air parametric sensor electrical signals, and, converting (ii) each outlet forced-air parametric sensor electrical signal of each of the at least one set of the outlet forced-air parametric sensor electrical signals, into a raw, or non-process corrected, value having magnitude and units appropriate for calculating moisture content and uniformity of solid plant matter 50 passing through device 10, by central processing unit 44. In particular, according to a functional relationship between each sensed and measured inlet forced-air parameter and the corresponding resulting inlet forced-air parametric sensor electrical signal, inlet forced-air parametric sensor electrical signals are converted into appropriate raw inlet forced-air parametric values as follows: T in (air) raw = F 1 [(s τ )i n ], H in (air) raw = F 2 [(s H )i„], and FR in (air) raw = F 3 [(s FR ) in ], where F, is a linear or non-linear function of inlet forced-air temperature sensor electrical signal, (sτ)in, F 2 is a linear or non-linear function of inlet forced-air humidity sensor electrical signal, (s^i n , and, F 3 is a linear or non-linear function of inlet forced-air flow rate sensor electrical signal, (s FR )i n , respectively. Moreover, each of the inlet forced-air parametric functions, F 1 [(sτ)in], F 2 [(sH,)in], and F 3 [(SFR) in], may also be a linear or non-linear function of any combination of the raw inlet forced-air parametric values, Tj n (air) ra , Hi n (air) raw , and FRj n (air) r w . Raw Inlet forced-air parametric values are determined at inlet conditions of the forced-air entering the volume of solid plant matter 50 via inlet forced-air elements 24. Similarly, according to a functional relationship between each sensed and measured outlet forced-air parameter and the corresponding resulting outlet forced-air parametric sensor electrical signal, outlet forced-air parametric sensor electrical signals are converted into appropriate raw outlet forced-air parametric values as follows: T out (air) raw = F 4 [(s τ )out], H out (air) raw = F 5 [(s H )out], and FRout(air) raw = F 6 [(s FR ) out ], where F 4 is a linear or non-linear function of outlet forced-air temperature sensor electrical signal, (sτ) out , F 5 is a linear or non-linear function of outlet forced-air humidity sensor electrical signal, (s H ) out , and, F 6 is a linear or non-linear function of outlet forced-air flow rate sensor electrical signal, (spR^ ut , respectively. Moreover, each of the outlet air parametric functions, F 4 [(sτ) ou t], F 5 [(sH) 0 ut], and F 6 [(sFR) 0U t] 5 may also be a linear or non-linear function of any combination of the raw outlet forced-air parametric values, T out (air) ra , H 0ut (air) ra , and FR oUt (air) ra . Raw outlet forced-air parametric values are determined at outlet conditions of the forced-air exiting solid plant matter 50 via outlet forced-air elements 26. Step 2 results in forming (i) at least one set of raw inlet forced-air parametric values, and, (ii) at least one set of raw outlet forced-air parametric values. Accordingly, each set of raw inlet forced-air parametric values includes (1) the raw inlet forced-air temperature value, Tj n (air) ra , (2) the raw inlet forced-air humidity value, Hi n (air) ra , and (3) the raw inlet forced-air flow rate value, FRj n (air) r w . Each set of raw outlet forced-air parametric values includes (1) the raw outlet forced-air temperature value, T out (air) raw , (2) the raw outlet forced-air humidity value, H out (air) ra , and (3) the raw outlet forced-air flow rate value, FR oUt (air) raw . Step 2 further includes storing each of the at least one set of raw inlet forced-air parametric values, and, each of the at least one set of raw outlet forced-air parametric values, by central processing unit 44. Preferably, there is forming and storing each set of raw inlet forced-air parametric values simultaneously to forming and storing a paired set of raw outlet forced-air parametric values, by central processing unit 44, according to operation of the electro-mechanically paired and axially aligned inlet and outlet forced-air elements 24 and 26, and corresponding sets 28 and 30 of inlet and forced-air outlet parametric sensors 32 - 42, respectively, as described above and illustratively shown by 52 and 54. Step 2 preferably includes process correcting (i) each value of the at least one set of raw inlet forced-air parametric values, and, (ii) each value of the at least one set of raw outlet forced-air parametric values, for forming (i) at least one set of process corrected inlet forced-air parametric values, and, (ii) at least one set of process corrected outlet forced-air parametric values. Process correcting of the raw forced-air parametric values, obtained and stored according to Step 1, is performed in order to account for the affects, typically, non-linear in nature, of secondary operating parameters of the drying or cooling forced-air treatment during the step of sensing and measuring inlet and outlet forced-air parameters by respective inlet forced-air parametric sensors 32, 34, and 36, and outlet forced-air parametric sensors 38, 40, and 42, for generating sets of inlet and outlet forced-air parametric sensor electrical signals, while the forced-air continuously or discontinuously enters and exits device 10 and the volume of solid plant matter 50, and, while solid plant matter 50 continuously or discontinuously enters and exits device 10. Calibration and process related empirical data obtained and stored according to operating device 10 as described above, are used in the step of process correcting the raw forced-air parametric values. Calibration and process related empirical data features, for example, determinations of moisture content and uniformity made during conditions involving well characterized and controlled primary operating parameters of forced-air temperature, T(air), humidity, H(air), and flow rate, FR(air), and, well characterized and controlled secondary operating parameters of (1) the volumetric bulk material transport rate, hereinafter referred to as V Bu i k (spm), of solid plant matter 50 transported by solid plant matter transport mechanism 16, such as a conveyor, through drying or cooling device 10 during the on-line drying or cooling forced-air treatment, where V Bu i k (spm) is a function of the configuration or volume of bulk solid plant matter 50 fed onto, and situated on, solid plant matter transport mechanism 16, and a function of the linear speed or velocity of solid plant matter transport mechanism 16, (2) the type, hereinafter referred to as Y(spm), of solid plant matter 10, and (3) physicochemical characteristics and properties, hereinafter referred to as D(spm), of solid plant matter 50, subjected to the drying or cooling forced-air treatment. For example, D(spm) is a function of the density, among other physicochemical characteristics and properties, of solid plant matter 50. In particular, according to a functional relationship featuring each raw inlet forced-air parametric value and the secondary operating parameters of the drying or cooling forced-air treatment, raw inlet forced-air parametric values are process corrected for forming process corrected inlet forced-air parametric values as follows: T in (air) po = F PC1 [T in (air) raw , V Bu ι k (spm), Y(spm), D(spm)], H in (air) pc - Fpc 2 [H in (air) raw , V Bu i k (spm), Y(spm), D(spm)], and FR in (air) pc = F PC3 [FR in (air) raw , V Bu i k (spm), Y(spm), D(spm)]. In these relations, Fpci is a linear or non-linear function of the raw inlet forced-air temperature value, Tj n (air) raw , V Bu i k (spm), Y(spm), and D(spm); F P c 2 is a linear or non-linear function of the raw inlet forced-air humidity value, Hj n (air) ra , Vβ u i k (spm), Y(spm), and D(spm); and, Fpc 3 is a linear or non-linear function of the raw inlet forced-air flow rate value, FRj n (air) raw , VB u i k (spm), Y(spm), and D(spm), respectively. Similarly, according to a functional relationship featuring each raw outlet forced-air parametric value and the secondary operating parameters of the drying or cooling forced-air treatment, raw outlet forced-air parametric values are process corrected for forming corresponding process corrected outlet forced-air parametric values as follows: T out (air) pc = Fp C4 [T out (air) raw , V Bu ι k (spm), Y(spm), D(spm)], H 0ut (air) pc = Fp C5 [H ou t(air) ra , V Bu]k (spm), Y(spm), D(spm)], and FR oUt (air) pc = F P c 6 [FRo Ut (air) raw , V BuIk (spm), Y(spm), D(spm)]. In these relations, Fpc 4 is a linear or non-linear function of the raw outlet forced-air temperature value, T out (air) r , N Bu i k (spm), Y(spm), and D(spm); Fpcs is a linear or non-linear function of the raw outlet forced-air humidity value, H out (air) raw , NBui k ($pm), N(spm), and D(spm); and, Fpc 6 is a linear or non-linear function of the raw outlet forced-air flow rate value, FR oUI (air) ra , V Bu i k (spm), Y(spm), and D(spm), respectively. Step 2 results in forming (i) at least one set of process corrected inlet forced-air parametric values, and, (ii) at least one set of process corrected outlet forced-air parametric values. Accordingly, each set of process corrected inlet forced-air parametric values includes (1) the process corrected inlet forced-air temperature value, Tj n (air) pc , (2) the process corrected inlet forced-air humidity value, Hj n (air) pc , and (3) the process corrected inlet forced-air flow rate value, FRi n (air) pc . Each set of process corrected outlet forced-air parametric values includes (1) the process corrected outlet forced-air temperature value, T out (air) p0 , (2) the process corrected outlet forced-air humidity value, H 0ut (air) pc , and (3) the process corrected outlet forced-air flow rate value, FR oUt (air) pc . Step 2 preferably further includes storing each of the at least one set of process corrected inlet forced-air parametric values, and, each of the at least one set of process corrected outlet forced-air parametric values, by central processing unit 44. In Step 3, there is calculating, and storing, a moisture content value of the solid plant matter, hereinafter referred to as W(spm), passing through the device, from each set of process corrected inlet forced-air parametric values and each set of process corrected outlet forced-air parametric values, obtained in Step 2. Preferably, there is calculating and storing a moisture content value of the solid plant matter, W(spm), from each set of process corrected inlet forced-air parametric values and each paired set of process corrected outlet forced-air parametric values, by central processing unit 44, according to operation of the electro-mechanically paired and axially aligned inlet and outlet forced-air elements 24 and 26, and corresponding sets 28 and 30 of inlet and forced-air outlet parametric sensors 32 - 42, respectively, as described above and illustratively shown by 52 and 54. In particular, there is calculating a plurality of moisture content values of solid plant matter 50, W(spm), passing through device 10, according to case (1) as a continuous or discontinuous function of time, t, and/or, according to case (2) as a continuous or discontinuous function of position, p, from the plurality of sets of process corrected inlet forced-air parametric values and the corresponding plurality of sets of process corrected outlet forced-air parametric values. In case (1), for a given value of a position, p m , of solid plant matter 50 within device 10, in the range between solid plant matter inlet 12 and solid plant matter outlet 14, moisture content of solid plant matter 50 is determined as a function of time, t, by calculating the moisture content value of solid plant matter 50, W(spm), at position p m for at least two values of time, t n , where m and n are each integers used for indexing specific values of position, p, and specific values of time, t, respectively. Case (1) enables generating a time profile of moisture content values, W t (spm; p m ), for any position, p m , of solid plant matter 50 subjected to the drying or cooling forced-air treatment. Alternatively, in case (2), at a given instant of time, t n , of solid plant matter 50 within device 10, in the range between solid plant matter 50 entering solid plant matter inlet 12 and exiting solid plant matter outlet 14, moisture content of solid plant matter 50 is determined as a function of position, p, by calculating the moisture content value of solid plant matter 50, W(spm), at time, t n , for at least two values of position, p m . Case (2) enables generating a position profile of moisture content values, W p (spm; t n ), at any time, t n , of solid plant matter 50 subjected to the drying or cooling forced-air treatment. The method for calculating at least one moisture content value of solid plant matter 50, W(spm), passing through device 10, as a continuous or discontinuous function of time, t, according to case (1), and/or, as a continuous or discontinuous function of position, p, according to case (2), from the at least one set of process corrected inlet forced-air parametric values, process corrected inlet forced-air temperature, Ti n (air) pc , process corrected inlet forced-air humidity, Hi n (air) p0 , and process corrected inlet forced-air flow rate, FRj n (air) pc , and the at least one set of process corrected outlet forced-air parametric values, process corrected outlet forced-air temperature, T out (air) pc , process corrected outlet forced-air humidity, H out (air) pc , and process corrected outlet forced-air flow rate, FR oUt (air) pc , obtained in Step 2, is herein described according to the following sub-steps of Step 3: In sub-step 1, of Step 3, there is obtaining, and storing, values of maximum water partial pressure, P max (water), corresponding to the saturation pressure of water, in the forced-air, capable of entering with process corrected inlet forced-air temperature value, Tj n (air) pc , and capable of exiting with process corrected outlet forced-air temperature value, T out (air) pc , solid plant matter 50, hereinafter referred to as P max i n (water), and, P max out (water), respectively, preferably, by central processing unit 44. P max i n ( ater) and P max out (water) may be obtained by calculation or by using a look-up-table. By calculation, there is evaluating any one of a variety of known standard functional relationships, hereinafter referred to as F [T(air)], between the saturation pressure of water in air, P max (water), and air temperature, T(air), at the process corrected inlet forced-air temperature value, Tj n (air) pc , and, at the process corrected outlet forced-air temperature value, T out (air) pc , whereby P max i n (water) = F 7 [T(air); for T(air) = T in (air) pc ], and, P max out (water) = F 7 [T(air); for T(air) = T out (air) pc ], respectively. Alternatively, P max j n (water) and P max out (water), may be obtained by central processing unit 44 identifying and selecting the value of P max (water) at the process corrected inlet forced-air temperature value, Tj n (air) p0 , and, P max (water) at the process corrected outlet forced-air temperature value, T out (air) pc , from a database stored as part of central processing unit 44, featuring calculated or empirical values of saturation pressure of water, P ma (water), versus air temperature, T(air), obtained from an appropriate look-up-table. The values of P max j n (water) and P max ou t( water) are then stored by central processing unit 44. In sub-step 2, of Step 3, there is calculating, and storing, values of maximum water concentration, C ax (water), corresponding to the saturation concentration of water, in the forced-air, capable of entering with process corrected inlet forced-air temperature value, Tj n (air) pc , and capable of exiting with process corrected outlet forced-air temperature value, T out (air) pc , solid plant matter 50, hereinafter referred to as C ax i n (water), and, C max out ( ater), respectively, preferably, by central processing unit 44. C max i n (water) and C max out ( ater) are obtained by calculation, by evaluating any one of a variety of known standard functional relationships, hereinafter referred to as F 8 [P(water), T(air)], relating the water concentration in air, C(water), to the water partial pressure in air, P(water), and the air temperature, T(air), according to C(water) = F 8 [P(water), T(air)], where C(water) is expressed in dimensions of mass of water per unit volume of air. Accordingly, C max j n (water) = F 8 [P(water), T(air); for P(water) = P max i n (water), and T(air) = T in (air) pc ], and, C max out (water) = F 8 [P(water), T(air); for P(water) = P max out (water), and T(air) = T out (air) pc ], respectively. For the assumption that the water in the forced-air behaves as an ideal gas, entering and exiting the volume of solid plant matter 50, during the drying or cooling forced-air treatment, the standard 'ideal gas law', PV = nRT, where P is the partial pressure of n moles of a gas within volume V, at temperature T, and R is the universal gas constant, can be used for obtaining the functional relationship, F 8 [P(water), T(air)], relating the water concentration in the forced-air, C(water), to the water partial pressure in the forced-air, P(water), and the forced-air temperature, T(air). Accordingly, n / V = m / (MN) = P / (RT), where m is the mass and M is the mass molecular weight, of the gas at temperature, T. For the gas concentration expressed in dimensions of mass per unit volume, C = m / V = (MP) / (RT), thus, F 8 [P(water), T(air)] = [M(water)P(water)] / [RT(air)], and, C(water) = [(M(water)P(water)] / [RT(air)]. Therefore, C ax in (water) and C max ou t( water) are obtained by evaluating the following formulas: C max in (water) = [M(water) P max in (water)] / [RT in (air) pc ], and similarly, C max 0ut (water) = [M(water) P max out (water)] / [RT out (air) pc ], where P max j n (water) and P max out (water) are obtained from sub-step 1. The values of C maX i n (water) and C max out ( ater) are then stored by central processing unit 44. In sub-step 3, of Step 3, there is calculating, and storing, values of actual water concentration, C actual (water), in the forced-air, entering with process corrected inlet forced-air temperature value, Ti n (air) pc , and exiting with process corrected outlet forced-air temperature value, T out (air) pc , solid plant matter 50, hereinafter referred to as C actuaI i n (water), and, C actual out (water), respectively, preferably, by central processing unit 44. Applying the same analysis used in sub-step 2, C actuaI j n (water), and, C ctual o ut ( ater), are obtained by evaluating the formulas, C actual i n (water) = [M(water) P actual in (water)] / [RT in (air) pc ], and similarly, C actual out (water) = [M(water) P actual out (water)] / [RT out (air) pc ], where P actual in (water) and P actual out (water) correspond to actual water partial pressure in the forced-air, entering and exiting, respectively, the volume of solid plant matter 50, during the drying or cooling forced-air treatment. For evaluating these formulas, the values of actual water partial pressure in the forced-air, P actual j n (water) and P ac ual out (water), entering and exiting, respectively, the volume of solid plant matter 50, are related to the values of maximum water partial pressure in the forced-air, P max j n (water) and P max out (water), capable of entering and exiting, respectively, the volume of solid plant matter 50, obtained from sub-step 1, by using the empirically determined process corrected forced-air parametric values of humidity entering and exiting the volume of solid plant matter 50 during the drying or cooling forced-air treatment, process corrected inlet forced-air humidity value, H; n (air) pc , and process corrected outlet forced-air humidity value, H out (air) pc , respectively, obtained through Step 6, and stored by central processor unit 44. Since water partial pressure in the forced-air, P(water), is directly proportional to humidity of the forced-air, H(air), [P actual in (water) / P max in (water)] = [H actual in (air) / H max in (air)], and, [P actuaI 0Ut (water) / P max out (water)] = [H actual out (air) / H max out (air)], where H actual i n (air) and H raaX j n (air) correspond to actual and maximum inlet forced-air humidity values, respectively, and, H actual out (air) and H max out (air) correspond to actual and maximum outlet forced-air humidity values, respectively. Accordingly, P actual j n (water) = P max in (water)[H actual in (air) / H max in (air)], and, P actual out (water) = P max out (water)[H actual 0ut (air) / H max out (air)]. In these formulas, H actual i n (air) and H actual out (air) are equivalent to the empirically determined process corrected forced-air parametric values of humidity, Hj n (air) pc , and H 0ut (air) pc , respectively, obtained through Step 2, during actual operation of the method and device or the present invention, and, H max j n (air) and H max out (air) are empirically determined by operating the method and device of the present invention, through Step 2, at established maximum humidity forced-air values, but at the same process corrected forced-air temperature and flow rate values, Tj π (air) pc , T ou t(air) pc , FR in (air) pc , and FR o ut(air) pc , used for measuring the actual Hi n (air) pc and H 0Ut (air) pQ , for obtaining the maximum values of inlet and outlet forced-air humidity. These formulas for P max in(water) and P max ou t(water) are now used in the previously described formulas for C ao ual i n (water), and C actual ou t(water), respectively, as follows: C actual in (water) = [M(water)P max in (water)H in (air) pc ] / [RT in (air) p Η ιnax in (air)], and similarly, C actual out (water) = [M(water)P max out (water)H out (air) pc ] / [RT out (air) pc H max out (air)], where a value for each term of these formulas is previously determined and stored by central processing unit 44. The values of C actuaI i n (water) and C actual out ( ater) are then stored by central processing unit 44. In sub-step 4, of Step 3, there is determining the implementing status, as 'normal' or 'abnormal', of the method and device for determining the moisture content and uniformity of solid plant matter 50 during the on-line drying or cooling forced-air treatment, preferably, by central processing unit 44. Determining the implementing status represents a built-in automatic quality control checking procedure during implementation of the method and device 10 of the present invention. Normal, or, abnormal, implementing status corresponds to normal, or, abnormal, implementation of the method and device 10, in general, and any number or combination of method steps and sub-steps, and device units, mechanisms, elements, and components, in particular. This includes, for example, the presence of all normal, or, one or more abnormal, values of data and/or information input into central processing unit 44, and for example, normal, or, abnormal, operation of device 10. For the condition of a normal implementing status, implementation of the method and device 10 continue for determining the moisture content and uniformity of solid plant matter 50 during the on-line drying or cooling forced-air treatment. For the condition of an abnormal implementing status, there is indicating, by central processing unit 44, that implementation of the method and device 10 is abnormal, leading to checking the method and device 10 by an operator, an inspecting device, or both (not illustrated). For performing sub-step 4, of Step 3, there is calculating and assigning, values of the quality, Q[C actual (water)], of the values of the actual water concentration in the forced-air, entering and exiting solid plant matter 50, C actual i„(water) and C actual out (water), respectively, at the process corrected inlet and outlet forced-air temperature values, humidity values, and flow rate values, T; n (air) pc , Hi n (air) pc , FRi n (air) pc , and, T out (air) pc , H ou t(air) pc , and FR out (air) pc , respectively, hereinafter referred to as Q n [C actual j n (water)], and, Q out [C actual out (water)], respectively, preferably, by central processing unit 44. The quality, Q[C actuaI (water)], is herein defined as the ratio of the value of the actual water concentration in the forced-air, C aotual (water), to the value of the maximum water concentration in the forced-air, C max (water), at the process corrected forced-air temperature values, such that, Q[C actual (water)] = [C actual (water) / C max (water)]. Accordingly, the following formulas are used for calculating and assigning values of the quality of the actual water concentration in the forced-air entering and exiting solid plant matter 50 during the drying or cooling forced-air treatment: Q[C actual in (water)] = [C actual in (water) / C max in (water)], and, Q[C actual out (water)] = [C actual out (water) / C max out (water)]. During normal implementation of the method and device 10 of the present invention, for a given set of process corrected forced-air parametric values, the value of the actual water concentration in the forced-air, C actual (water), is less than or equal to, the value of the maximum water concentration in the forced-air, C max (water), such that the value of the quality of the actual water concentration in the forced-air, Q[C actual (water)], is less than or equal to one, and this value is assigned as a 'normal implementing status' by central processing unit 44. At forced-air parametric conditions where the value of the actual water concentration is equal to the value of the maximum water concentration, corresponding to water saturation in the forced-air, C actuaI (water) equals C max (water), such that Q[C actuai (water)] is equal to one, this value is also assigned as a 'normal implementing status' by central processing unit 44. If the value of the actual water concentration is greater than the value of the maximum water concentration, in the forced-air, whereby, C actual (water) is greater than C max (water), such that Q[C actuaI (water)] is greater than one, this value is assigned as an 'abnormal implementing status' by central processing unit 44. Therefore, determining the implementing status of the method and device 10 is according to fulfillment of one of the following four conditions: 1. For both Q[C actua, in (water)], and, Q[C actual 0Ut ( ater)], less than one, the implementing status is assigned as normal, and implementation of the method and device 10 continues with sub-step 5, of Step 3. 2. For both Q[C ac ual in (water)], and, Q[C actual 0Ut (water)], equal to one, the implementing status is assigned as normal, and implementation of the method and device 10 continues with sub-step 5, of Step 3. 3. For either Q[C actual in (water)], or, Q[C actual 0Ut (water)], greater than one, the implementing status is assigned as abnormal, and implementation of the method and device 10 continues with checking the method and device 10 by an operator, an inspecting device, or both. 4. For both Q[C actual in (water)], and, Q[C actual 0Ut (water)], greater than one, the implementing status is assigned as abnormal, and implementation of the method and device 10 continues with checking the method and device 10 by an operator, an inspecting device, or both. In sub-step 5, of Step 3, there is calculating, and storing, the at least one moisture content value of solid plant matter 50, W(spm), passing through device 10, during the on-line drying or cooling forced-air treatment, from values of the actual water concentration in the forced-air, entering and exiting solid plant matter 50, C actual j n (water) and C aotual out (water), respectively, at the process corrected inlet and outlet forced-air temperature values, humidity values, and flow rate values, Tj π (air) pc , Hj n (air) pc , FRj n (air) pc , and, T out (air) pc , H out (air) pc , and FR oUt (air) pc , respectively, preferably, by central processing unit 44. Moisture content of solid plant matter 50, W(spm), is calculated by evaluating a linear or nonlinear function of the actual water concentration in the forced-air, entering and exiting solid plant matter 50, C actual j n (water) and C actual out (water), respectively, hereinafter referred to as F 9 [C actual i n (water), C actual out (water)], at the process corrected inlet and outlet forced-air temperature values, humidity values, and flow rate values, such that W(sρm) = F 9 [C actual in (water), C actual out (water)], where W(spm) is evaluated as a percent. W(spm), as a percent, is proportional to the ratio of the mass of water present in solid plant matter 50 to the mass of solid plant matter 50 in a state or form of dryness. W(spm) = 100 x (mass of the water in the solid plant matter) / (mass of the dry solid plant matter). The following form of F 9 [C actuaI in (water), C actuaI 0Ut (water)] is used for calculating values of moisture content of solid plant matter 50: W(spm) = ki [C actual in (water) + [(C actual out (water) - C actual in ( ater)) / (k 2 k 3 ) f ] ] . In this formula for W(spm), ki, k 2 , and k 3 , are empirically determined constants, and f is a linear or nonlinear function of the process corrected outlet forced-air flow rate value, FR oUt (air) po , such that f = F 1 o[FR ou t(air) pc ]. An exemplary form of Fιo[FR oUt (air) pc ] is FR out (air) pc raised to the power of h, or [FR oUt (air) c ] h , where h is an empirically determined constant. Values of C actual j n (water) and C actual out (water), at the process corrected inlet and outlet forced-air parametric conditions, were determined and stored by central processing unit 44, according to sub-steps 1 - 3, of Step 3, and values of FR out (air) p0 were determined and stored by central processing unit 44, through Step 2. Thus, all data needed for evaluating the formula of W(spm) are known. In Step 4, there is calculating, and storing, a uniformity value of solid plant matter 50, hereinafter referred to as U(spm), passing through device 10, from at least two moisture content values, W(spm), calculated in Step 3, preferably, by central processing unit 44. Preferably, there is calculating a uniformity value of the solid plant matter, U(spm), from at least two moisture content values which are calculated from the at least one set of process corrected inlet air parametric values and the at least one paired set of process corrected outlet air parametric values, by central processing unit 44, according to operation of the electro-mechanically paired and axially aligned inlet and outlet forced-air elements 24 and 26, and corresponding sets 28 and 30 of inlet and forced-air outlet parametric sensors 32 - 42, respectively, as described above and illustratively shown by 52 and 54. In particular, there is calculating a plurality of uniformity values of solid plant matter 50, U(spm), passing through device 10, according to case (1) as a continuous or discontinuous function of time, t, and/or, according to case (2) as a continuous or discontinuous function of position, p, from the plurality of moisture content values calculated and stored according to Step 3. In case (1), for a given value of a position, p m , of solid plant matter 50 within device 10, in the range between solid plant matter inlet 12 and solid plant matter outlet 14, uniformity of solid plant matter 50 is determined as a function of time, t, from at least two moisture content values, W t (spm; p m ), obtained from the previously determined time profile of moisture content values. Case (1) enables generating a time profile of uniformity values, U t (spm; p m ), for any position p m , of solid plant matter 50 subjected to the drying or cooling forced-air treatment. Alternatively, in case (2), at a given instant of time, t n , of solid plant matter 50 within device 10, in the range between solid plant matter 50 entering solid plant matter inlet 12 and exiting solid plant matter outlet 14, uniformity of solid plant matter 50 is determined as a function of position, p, from at least two moisture content values, W p (spm; t n ), obtained from the previously determined position profile of moisture content values. Case (2) enables generating a position profile of uniformity values, U p (spm; t n ), at any time, t n , of solid plant matter 50 subjected to the drying or cooling forced-air treatment. Standard techniques of statistical analysis can be used for calculating uniformity values, U(spm), of solid plant matter 50 from moisture content values, W(spm), of solid plant matter 50. For example, in case (1), the time profile of uniformity values, U t (spm; p m ), for any position, p m , of solid plant matter 50 subjected to the drying or cooling forced-air treatment, can be generated by evaluating a plurality of ratios of a moisture content value, W t (spm; p m ), to the average of at least two moisture content values, [Wt(spm; p m )]average, for the position p m , such that: U t (spm; p m ) = [W t (spm; p m )] / [W t (spm; p m )]average. Alternatively, in case (2), the position profile of uniformity values, U p (spm; t n ), at any time, t n , of solid plant matter 50 subjected to the drying or cooling forced-air treatment, can be generated by evaluating a plurality of ratios of a moisture content value, W p (spm; t n ), to the average of at least two moisture content values, [W p (spm; t n )]average, at time, t n , such that: U p (spm; t n ) = [W p (spm; t n )] / [W p (sρm; t n )]avera g e. The method and device of the present invention enable determining values of moisture content and uniformity corresponding to the entire volume of moving solid plant matter, based on accurately and reproducibly measuring a multiple of operating parameters during the drying or cooling forced-air treatment. These values are appropriately used for achieving high levels of process optimization and control of the drying or cooling forced-air treatment, thereby contributing to optimization and control of an overall manufacturing sequence for producing consumer end products containing solid plant matter raw materials. While the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
