## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is a continuation-in-part of U.S. patent application Ser. No. 12/633,763 filed Dec. 8, 2009, now U.S. Pat. No. 8,534,501 which in turn claims priority to U.S. Provisional Patent Application No. 61/120,772, filed on Dec. 8, 2008.


BACKGROUND OF THE DISCLOSURE
1. Field of the Disclosure
The present disclosure relates generally to an integrated method and system for dispensing and blending/mixing beverage flavor/ingredients, thereby producing a beverage, e.g., a smoothie. More particularly, the present disclosure relates to a system and method for storing the flavor/ingredients, and dispensing the same. The present disclosure also relates to a system and method for cleaning the flavor/ingredient dispensing system in place.
2. Description of Related Art
Multiple steps are involved in creating a beverage or drink, for example, a smoothie drink, from beginning to end, and potential issues can occur at all stages. After ice is added to a blender pot for mixing the beverage, juice and any additional fruit or flavor “mix-in” is added by an operator as well. A size of cup is chosen, and the drink is poured. This last step presents the largest chance for waste. Since the employee must portion the ingredients by hand, any overspill of the drink is left in the blender pot. At each step during this manual process, portion control is compromised, and money is potentially wasted on excess ingredients.
Once the order is complete and the customer has his or her drink, there is one last step to finalize the process—the method of manually cleaning the flavor/ingredient dispensing system, to prevent the transfer of flavors and germs. Depending on where the dispensing system is located within or in relation to the beverage machine, the dispensing system may be very difficult and inconvenient to clean, which adds significantly to the time and labor required for maintenance. Also, flavor contamination can be a serious threat if customers have food allergies.
Each step in this process to create a smoothie takes time, typically four to five minutes, and that time could be better spent serving customers or taking more food and beverage orders, directly contributing to the bottom line.
Although premium beverages such as smoothies are growing in popularity, most quick-service restaurants (QSRs) are unable to offer customers these options due to the time limitations of the quick-serve world. Those QSR owners that do opt to serve smoothies are confronted with a common set of challenges—mainly how to sell the same franchised drink time after time with existing labor and equipment limitations.
Accordingly, it has been determined by the present disclosure, there is a need for an assembly that dispenses and mixes beverage flavors/ingredients with ice in one integrated system, and thereafter can be cleaned in place, for immediate reuse without subsequent flavor contamination.
SUMMARY OF THE DISCLOSURE
An assembly for dispensing and mixing a beverage is provided that includes an ice dispenser assembly, an flavor/ingredient dispensing module, and a blender/mixer/cleaning module as one integrated assembly.
The flavor/ingredient dispensing module comprises: a refrigerated housing, at least one ingredient container disposed within the housing, an ingredient conduit disposed between the ingredient container and the dispensing apparatus, and a pump that causes the ingredient to move from the ingredient container, through the ingredient conduit and into the dispensing apparatus under pressure.
A controller preferably provides integrated control between menu selection, portioning of ice and dispensing of the ingredient(s) based upon the menu selection, and blending and/or mixing based upon the menu selection. The controller also activates the cleaning mode.
The dispensing apparatus is a dispensing nozzle which comprises a centrally disposed ice dispensing conduit and a plurality of ingredient conduits disposed about the ice dispensing conduit, wherein each ingredient conduit is isolated from other ingredient conduits and the ice dispensing conduit, whereby product and/or flavor contamination is avoided.
Thus, in one embodiment, the present disclosure provides an integrated beverage blending system. The system comprises an ice portion control module, an ingredient module, an ice dispensing conduit in communication with the ice portion control module, and an ingredient dispensing valve removably connected to the ice dispensing conduit and in communication with the ingredient module. Ice is dispensed into a beverage container via the ice dispensing conduit and the ingredient is dispensed into the beverage container via the ingredient dispensing valve. The ingredient module comprises a housing, an ingredient container disposed within the housing, an ingredient conduit disposed between the ingredient container and the ingredient dispensing valve, and a device that causes the ingredient to move from the ingredient container, through the ingredient conduit, and through the ingredient dispensing valve under pressure. Each ingredient conduit is isolated from other ingredient conduits and the ice dispensing conduit, whereby product and/or flavor contamination is avoided.
The above-described and other advantages and features of the present disclosure will be appreciated and understood by those skilled in the art from the following detailed description, drawings, and appended claims.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and in particular to FIGS. 1-5, an exemplary embodiment of an assembly that dispenses and mixes beverages (“assembly”), according to the present disclosure is generally referred to by reference numeral 100. Assembly 100 makes ice, dispenses flavors/ingredients and ice into a serving cup 15, and then blends or mixes to form a beverage. One such beverage, for example, is a smoothie that preferably includes a flavor ingredient and ice mixed together. Assembly 100 has an onboard ice maker, ice storage and portion control module 300, a flavor/ingredient dispensing module 1100, and a blender/mixer/cleaning module 303. Assembly 100 shows ice maker, ice storage and portion control module 300, flavor/ingredient dispensing module 1100, and blender/mixer/cleaning module 303 as one integrated assembly. It is contemplated by the present disclosure that one or more of ice maker, ice storage and portion control module 300, flavor/ingredient dispensing module 1100, and blender/mixer/cleaning module 303 may be separate from assembly 100, however, it is preferable that they are all integrated into a single assembly 100. That is, vertical placement of ice maker, ice storage and portion control module 300, flavor/ingredient dispensing module 1100, and blender/mixer/cleaning module 303 reduces a size of assembly 100 and its associated flooring footprint in comparison to three separate and distinct machines.
Assembly 100 has a housing that includes a lower wall 6, an upper wall 7, side walls 11 and 12, and a top wall 13. Lower wall 6 has a container holder portion 20. The housing connects cup supports 4 and 5 that secure cup holders 14 to assembly 100. Cup holders 14 removably hold cups 15 therein. Cup 15 may be disposable or reusable single serving cups. If cup 15 is disposable, such as, for example, paper or plastic cups, the beverage dispensed and mixed within cup 15 may be served directly to a customer eliminating the step of pouring the beverage into a serving cup and eliminating labor needed to wash an additional container. Cup 15 may be any size, such as, for example, about 10 ounces to about 32 ounces.
FIGS. 6 and 7 provide an overview of the integrated assembly 100 according to the present disclosure, wherein assembly 100 comprises: flavor/ingredient dispensing module 1100, ice maker, ice storage and portion control module 300 and a pair of blender/mixer/cleaning modules 303 disposed on opposite sides of dispensing nozzle 304. Further aspects of assembly 100 are discussed in greater detail in co-pending U.S. patent application having attorney docket no. 253.8867USU, entitled “AN INTEGRATED METHOD AND SYSTEM FOR DISPENSING AND BLENDING/MIXING BEVERAGE INGREDIENTS,” filed on Dec. 8, 2009, which is herein incorporated by reference.
Referring to FIGS. 8-17, flavor/ingredient dispensing module 1100 is shown. Referring to FIG. 12, flavor/ingredient dispensing module 1100 has an ingredient housing 1110. Ingredient housing 1110 can include a refrigeration cycle, such as, for example, a vapor compression cycle that includes a compressor, condenser, expansion valve, and evaporator. One or more of the compressor, condenser, expansion valve, and evaporator may be integral with flavor/ingredient dispensing module 1100 or remote from the rest of flavor/ingredient dispensing module 1100. For example, compressors may create undesirable noise and may be remotely located from the rest of assembly 100.
Ingredient housing 1110 can cool one or more holders or cassettes 1115. Holders 1115 each hold a flexible container (not shown) via a hanging rod 1116 (see FIG. 17). The flexible container can be, for example, a bag, that contains an ingredient for the beverage. Hanging rod 1116 can thread holes in the top of the flexible container, to support the container. The ingredient can be cooled while stored in holders 1115 by ingredient housing 1110, so that the ingredient is maintained at a food-safe temperature. Alternatively, ingredient housing 1110 can keep holders 1115, and the containers within them, at ambient temperature. The bag may be a 2.5 gallon bag. The ingredient may be a flavored liquid or mix. Each of the containers within holders 1115 can hold different ingredients, or alternatively, two or more of the containers can hold the same ingredient. Ingredient housing 1110 has a door 1111 and wheels 1113.
In the shown embodiment, flexible containers would be held in a vertical orientation, which helps to ensure a maximum extraction of ingredient from the flexible container. The present disclosure contemplates, however, a horizontal orientation for holder 1115, which is shown in FIG. 17a and discussed in greater detail below.
Each of holders 1115 has a connection tube 1117 connected thereto, so that the ingredient flows out of the flexible container, into one end of connection tube 1117, and out of the other. Connection tube 1117 can be integrally formed with the flexible container, or alternatively there can be a connector on the flexible container that allows for connection to connection tube 1117 and/or holder 1115. Connection tube 1117 has an aperture or gap 1118 (see FIG. 13a) at an end of connection tube 1117 that is connected to holder 1115 and the flexible container. Gap 1118 is a small opening or notch, for allowing substantially all of the flavor/ingredient disposed in the container to be removed without concern regarding the collapsing of the container (not shown). As the container is emptied of its contents, it collapses on itself, and may block the opening of connection tube 1117 that is connected to it. This would impede the further extraction of the flavor/ingredient from the flexible container. Gap 1118 allows more ingredient to be extracted, even in a situation where the container holding the ingredient is collapsed over the end of connection tube 1117.
Connection tube 1117 of each of holders 1115 is connected to a conduit 1119 that passes through a base 1120. As shown in FIG. 13, conduit 1119 may connect to a pump rack 1123. Pump rack 1123 has one or more pumps 1125 that selectively move a portion of the ingredient from the flexible container in holders 1115 through connection tube 1117, to conduit 1119, to a line conduit 1130, and to dispenser nozzle 304 to dispense the ingredient out of assembly 100, for example, to cup 15. The ice and the ingredient are dispensed into cup 15 but are segregated from each other until dispensed into cup 15 to prevent contamination. There is an ingredient dispenser tube for each ingredient in each of holders 1115 and one ice nozzle in nozzle 304.
FIGS. 7 and 14 shows dispenser nozzle 304 as being injection molded from a plastic material, so that an ice-dispensing chute and one or more ingredient conduits are integrally formed into one component. In FIGS. 15-16c, dispenser nozzle 1304 is shown in detail. In this embodiment, nozzle 1304 has a central chute 1126 for dispensing ice into a cup 15, as described above. Nozzle 1304 can be used in place of nozzle 304. Nozzle 1304 has one or more ingredient valve blocks or assemblies 320 disposed around an exterior side of nozzle 1304, on an opposite side of nozzle 1304 from central chute 1126.
Valve assemblies 320 have one or more ingredient dispensing valves 322 connected thereto. Upper plate 328 and lower plate 329 are removably connected to each other, and can be used to secure valves 322. Assembly 320 can then be removably connected to dispenser nozzle 1304 as shown. In the embodiment shown in FIG. 15, there are three valve assemblies 320, each of which comprise three valves 322. However, the present disclosure contemplates different configurations, for example assemblies 320 that have one or more valves 322, or where one or more assemblies 320 are connected to dispenser nozzle 1304. The present disclosure also contemplates embodiments where different assemblies 320 have different numbers of valves 322. For example, a first assembly 320 can have one valve 322, a second assembly 320 can have two valves 322, and a third assembly 320 can have three valves 322.
As shown in FIG. 16c, valves 322 have an interior passage 323, a lower end 324 with a reversible dome 325 disposed therein, and upper end 327. Dome 325 has an upper surface 326 that is convex with respect to passage 323, i.e. that it extends in a direction toward upper end 327. Upper end 327 and passage 323 can be in fluid communication with conduit 1130, and thus ingredient holders 1115, as is discussed in greater detail below. Each valve 322 can be connected to a separate ingredient holder 1115.
Dome 325 has a slit or opening on upper surface 326. When the ingredient is being forced through passage 323 in the manner described above, dome 325 allows the ingredient to pass through the opening on upper surface 326. Dome 325 may partially or completely invert as the ingredient passes through the opening. When the ingredient is not flowing, e.g. when there is not significant pressure placed on upper surface 326 of dome 325, no ingredient passes through the opening thereon.
Valve 322 is highly advantageous in that it prevents ingredient from leaking outside of a refrigerated zone, and then being placed into a drink the next time the machine is used. Even after the flow of ingredient is shut off, there will be a residual flow of ingredient through the dispensing mechanism. In machines where valve 322 is not used, some of the ingredient can migrate outside of an area that is kept refrigerated. This can create an unsanitary situation, if the residual ingredient is mixed into a drink the next time the machine is used. Valve 322 prevents this from happening, since dome 325 is inverted, and prevents the residual flow from leaking out of passage 323. The only time when dome 325 will allow ingredient to pass through the opening therein is when there is a significant pressure placed dome 325, i.e. when ingredient is deliberately forced through.
In addition, assembly 320 can provide for more flexibility and ease of service than in other embodiments or devices. As shown in FIG. 15, assemblies 320 can be removably connected to dispenser nozzle 1304. This allows for easier servicing of dispenser nozzle 1304 and/or assemblies 320, and/or valves 322. It also allows for more flexibility in the number and configuration of assemblies 320 and valves 322.
As shown in FIG. 16a-c, valves 322 can be angled with respect to a central axis of dispenser nozzle 1304. The angled position of valves 322 allows for an easier connection to conduit 1130, and again, allows for easier servicing of assemblies 320 and valves 322. If the angle is too severe, cup 15 can tip over when ingredient is dispensed.
As shown in FIG. 14, conduit 1119 may connect to a pump 1125. Pump 1125 selectively moves a portion of the ingredient from the container in holders 1115 through connection tube 1117, to conduit 1119, to a line conduit 1130, and to dispenser nozzles 304 or 1304 to dispense the ingredient out of assembly 100, for example, to cup 15. Pump 1125 may be an air powered pump that may include a diaphragm. Pump 1125 may also be a pressure pump, or a peristaltic pump. When pump 1125 is a pressure pump, it provides a constant pressure within holder 1115, that is applied to the flexible container. Holder 1115 would have to be sealed for this to be effective. A solenoid can regulate flow of the ingredient out of the flexible container. When the solenoid is opened, the ingredient will flow out of the flexible container at a known rate, given that the pressure applied to the flexible container and the impedances of the system are also known, as discussed below. This pressurized pumping system has been found to be particularly effective for ingredients that include “stringy” components, such as pulp.
A portion of the ingredient, such as, for example, a fruit base, may be controlled by time. A controller maintains accuracy by determining an amount of the fruit base that has been delivered from the flexible container in holder 1115. As a fluid level decreases within the container within holder 1115, the controller allocates a longer delivery time to compensate for a decrease in head pressure within the container within holder 1115. Pump 1125 may be positive displacement and a controller controls the pumps on a time basis. The time can be adjusted to control portion accuracy. Assembly 100 may only dispense ice from ice maker, ice storage and portion control module 300 into cup 15 and not an ingredient from flavor/ingredient dispensing module 1100.
A water reservoir (not shown) can be within ingredient housing 1110, or alternatively can be located remotely from ingredient housing 1110. In either embodiment, the water reservoir can be used to provide water to the beverages made by the machine. In addition, the water reservoir can be used to clean out dispensing module 301 in place. This feature has the benefit of significantly reducing the amount of labor required to keep dispensing module 301 clean, and avoid flavor contamination when different ingredients or flavorings are switched out of ingredient housing 1110. The water reservoir can be connected to any point on the line for dispensing the ingredient to dispenser nozzles 304 or 1304. For example, the water reservoir can be connected to any of connection tube 1117, conduit 1119, or line conduit 1130. A manifold 1200, as shown in FIG. 18, can be used to connect the water reservoir to these components, either manually or through the use of solenoid valves.
For cleaning, clean water can be run through the ingredient dispensing system. Alternatively, detergent can be placed in the water reservoir, and/or in manifold 1200. The detergent can be in liquid or pill form. The water and/or the detergent is circulated through the flavor/ingredient dispensing system as described above, and then drained from ingredient housing 1110. The water reservoir is then filled again, and purged, to ensure that there are no residual detergent chemicals left in the system. The reservoir is then refilled.
As previously discussed, FIG. 17a shows another embodiment of an ingredient housing of the present disclosure, and is referred to by numeral 2110. Housing 2110 has ingredient holders 2115 therein, which are in a substantially horizontal (i.e. pitched) orientation, as opposed to the vertical orientation of holders 1115. As with holders 1115, a flexible container (not shown) can be disposed therein. In the horizontal orientation, each holder 2115 slides into ingredient housing 2110 using guides 2117. Guides 2117 are at a slight angle, and the ingredient within holders 2115 is thus pushed toward the rear of housing 2115 under the force of gravity. A connector (not shown) located at the back of holder 2115 can connect the flexible containers within holders 2115 to connection tube 1117, which is also at the back of ingredient housing 2110, so that the ingredient can be dispensed into cup 15 in the manner described above. In this embodiment, connection tube 1117 and conduit 1119 can be mounted and designed to mate with holders 2115 so that tube 1117 and conduit 119 give as holder 2115 is placed in housing 2110, to facilitate the connection of tube 1117 to holder 2115.
FIG. 20 shows a structure of control boards identifying that they are separate but interconnected. This provides flexibility in the design allowing additional boards to be added without re-designing the entire controller. FIG. 21 shows a user interface controller 401 that incorporates a button panel, such as a control panel 500 shown in FIG. 19, that an operator uses to select the drink as well as a computer that interconnects to other control boards. A communications board control board 402 provides a gateway for communication to various methods (web, modem, USB, and the like.). Mixer boards 403 and 404 are mixer control boards that contain logic controllers for the operation of mixer blender blade 255 and linear slides 240. Smart relay board 405 is a control board that houses switching relays for ice maker, ice storage and portion control module 300, flavor/ingredient dispensing module 1100, mixer spindle motor 240, linear slides 241, water solenoid 280, and air solenoid 220a. C-bus 406 is a communication interconnect. P-bus 407 is a wiring interconnect between boards.
