## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims two priorities of Chinese Patent Application No. 201410190921.9, filed on May 7, 2014 and Chinese Patent Application No. 201420230445.4, filed on May 7, 2014 in the SIPO (State Intellectual Property Office of the P.R.C).
FIELD OF THE INVENTION
The present invention relates to a one-step noodle forming mechanism with rolling and cutting, and in particular to a noodle machine integrated with producing and cooking, including the mechanism, belonging to the technical field of food processing.
BACKGROUND OF THE INVENTION
Noodles can be divided into sliced noodles, fresh noodles, dried noodles, and so on based on the different production processes. In hand rolled noodles, which are a type of fresh noodles, flour proteins are utilized to generate a great amount of gluten, which is distributed evenly in the noodles during the unique kneading and rolling process thereof. Gluten is composed of gliadin and glutenin. Since gluten has great extensibility and flexibility, the chewiness and taste of hand rolled noodles are better than other noodles. In prior art, due to the restrictions of the noodle producing processes and techniques, noodle producing machines fail to produce noodles with chewiness and texture equivalent to hand-rolled noodles.
Currently, the noodle producing machine commercially widely used produces noodles mostly through a pressing technique. It usually presses a flour-water mixture into a round disk shape first, then press the mixture into a sheet shape repeatedly, and finally slices the mixture into noodles with a blade, which is sliced noodles in daily life. Due to the lack of gluten proteins, sliced noodles are not chewy, have a hard texture, and taste significantly worse than hand rolled noodles.
Further, in the noodle pressing process, the process of repeatedly pressing and the process of slicing are conducted separately. In the noodle pressing process and storing process, it is required to scatter and put dry flour on noodles to prevent them from sticking together. During the cooking process, because the noodles are coated with the dry flour, the dry flour falls into the cooking pot with the noodles, making water sticky after the boiling water is repeatedly used, and affecting the quality of the cooked noodles. Therefore, when the pressed noodles are cooked on a large scale, it is required to replace the water in the cooking pot frequently, which is a great waste of flour, water, and energy.
In order to produce noodles with the chewiness and taste equivalent to or even better than hand rolled noodles through machines, the inventor made an effort to study the principles of hand rolled noodles as well as the functions and coordination of the various internal structures of noodle forming mechanisms. As a specific manifestation of the research results, the present invention provides a new type of a noodle forming mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
By reference to the accompanying drawings, the specific embodiments of a one-step noodle forming mechanism with rolling and cutting, which is referred to as the noodle forming mechanism for short, and a noodle machine integrated with producing and cooking provided by the invention are described in detail as follows:
The First Embodiment
Referring to FIG. 1 to FIG. 4, in a preferred embodiment of the present invention, a one-step noodle forming mechanism with rolling and cutting comprises multi-layer noodle roller sets 2 disposed on a machine frame 1 (the noodle roller sets in four layers are shown in FIG. 1), and noodle forming blades 4 disposed below the multi-layer noodle roller sets 2.
Referring to FIG. 2, in the multi-layer noodle roller sets in the four layers are shown in FIG. 1, the noodle roller set in each layer includes two rolling-relatively rollers 21 and a gap 22 formed between the two noodle rollers 21 allowing downward movement of dough. In the four layers of the noodle roller sets, the gap 22 in each layer of the noodle roller set gradually decreases in order from top to bottom. When the dough (dough ball) passes through the noodle roller sets in the four layers 2, the cross-section of the dough is gradually expanded, and the thickness of the dough is gradually thinned till the thickness of the dough is suitable to be sliced into noodles.
When the dough goes through the multi-layer noodle roller sets 2, in order to ensure that the process by which the noodle roller sets process the dough is equal to the hand rolling process, the intensity with which the multi-layer noodle roller sets process the dough should be determined and ensured. Therefore, the difference between the gaps in the noodle roller sets in two adjacent layers is supposed to be great. The gap (δm) in the noodle roller set in the lower layer is preferably between 1⁄3 and 2⁄3 of the gap (δ(m+1)) in the noodle roller set in the upper layer, which means 1⁄3×δ(m+1)<δm<2⁄3×δ(m+1). Meanwhile, the rolling rates of the multi-layer noodle roller sets should be designed. In the multi-layer noodle roller sets, in order from bottom to top, the rolling rate of the noodle roller set in each layer and the gap of the noodle roller set in each layer satisfy the following equation:

δm×nm×πdm<δ(m+1)×n(m+1)×πd(m+1)  Formula 1:

the total layer number of the multi-layer noodle roller sets is L, (L−1)≧m≧1, δm is the gap between the two noodle rollers in the noodle roller set in the m-th layer, nm is the rolling rate of the noodle rollers in the noodle roller set in the m-th layers, and dm is the diameter of the noodle rollers in the noodle roller set in the m-th layers. The diameters of the noodle rollers in the different layers can be the same or different.

In the embodiment as shown in FIG. 1, the total number of layers (L) of the multi-layer noodle roller sets is four, the diameters of the noodle rollers in the noodle roller sets in the four layers are the same, and the gaps of the noodle roller sets in the four layers in order from top to bottom are halved gradually. In order to obtain the equivalent results of machine-rolling to hand-rolling, the total layer number (L) of the multi-layer noodle roller sets can be raised up to 4-6 layers. Meanwhile, the gap in the noodle roller set in each layer can be adjusted accordingly based on formula 1. For smaller dough, the total layer number (L) of the multi-layer noodle roller sets should be fewer, preferably. When the total layer number of the multi-layer noodle roller sets is over six layers, due to the difference between the gaps in two adjacent layers being small, not enough gluten is able to be generated, and the result of rolling could not be ensured. If the total layer number is increased while the great difference between two adjacent gaps is maintained, the thickness of the noodles obtained as a result will be too thin and easily over-cooked, and will affect the chewiness and taste. On the other hand, when the total layer number (L) of the noodle roller sets is fewer than 4 layers, since the number of time which the noodle roller sets squeeze the dough are reduced, the gluten which is generated will not be enough, the elasticity and flexibility of the noodles will be not optimized, and the taste will be affected.
As shown in FIG. 1, the bottom of the machine frame 1 is provided with a cutting stand 3, the top of the cutting stand 3 is fixed to the machine frame 1, and the bottom of the cutting stand 3 is provided with a opening, which is a noodle outlet corresponding to the noodle forming blades 4 and allows the noodles sliced by the noodle forming blades 4 to pass. The cutting stand 3 is provided with a horizontal sliding slot 30, one end of the sliding slot is provided with an opening to the outside of the cutting stand, and the noodle forming blades 4 are disposed in the sliding slot 30, movable back and forth along the sliding slot 30, and removable from the opening. When the use of the noodle forming mechanism is complete, the noodle-forming blades 4 can be removed from the opening of the sliding slot 30 for cleaning and maintenance.
Referring to FIG. 2 and FIG. 3, the noodle forming blades 4 include multiple sets of blades for cutting noodles into different sizes, and each set of the blades includes two blades engaged with each other. Since the structure of the blades is known to a person of ordinary skill in the art, so the introduction of the structure is omitted here. In the embodiment as shown in FIG. 2, the noodle forming blades 4 comprise three blades: blades 41, blades 42, and blades 43, respectively, for processing wide noodles, medium noodles, and narrow noodles, which are noodles with three different widths. To ensure the smooth taste of the noodles, a scraper 44 is disposed below each blade, the edge of the scraper is attached to the outer surface of the lower part of the blade, as shown in FIG. 3, and a passage for passing noodles is formed between the two blades in the same set and between the two scrapers disposed below the blades.
Referring to FIG. 1, a motor 8 is disposed on the machine frame 1, the motor 8 drives the multi-layer noodle roller sets 2 and the noodle forming blades 4 to rotate through a gear transmission mechanism 7. The gear transmission mechanism 7 is composed of a plurality of mutually engaged gears disposed on two sides of the machine frame 1, and a plurality of driving shafts for linking the gears on the two sides. Furthermore, the cutting stand is provided with a clutch 5 and a shifter 6. The motor 8 drives one set of the blades of the noodle forming blades 4 through the gear transmission mechanism 7 and the clutch 5, and the shifter 6 is used for switching a different set of the blades to couple with the clutch 5. When the clutch 5 is coupled with a set of blades in the noodle forming blades 4, and the gap between the set of blades faces the gap between the noodle rollers in the lowest layer, so that the dough rolled by the multi-layer noodle roller set 2 directly enters the space between the blades and is sliced into noodles.
By reference to the accompanying FIG. 4, the gear transmission principle of the embodiments are described as follows:
As shown in FIG. 4, the motor 8 drives a gear 71 to rotate through a drive shaft, the gear 71 drives a gear 73 to rotate through a gear 72, the gear 73 is used for driving a noodle roller of the noodle roller set in the lowest layer to rotate, which is labeled as the noodle roller 21a. Meanwhile, gears 74, 75, 77 disposed on a drive shaft (shaft 1) of the noodle roller 21a together with the gear 73 rotate simultaneously. The gear 74 drives the noodle roller set in the second lowest layer to rotate by engaging a gear 80. The gear 75 drives the other noodle roller 21b of the noodle roller set in the same layer to rotate simultaneously by engaging a gear 76. The gear 77 drives a gear 79 to rotate through a gear 78. The gear 79 drives a set of blades to rotate through clutch 5. At the same time, gears 81, 82 disposed on the same drive draft (draft 3) together with the gear 80 rotate simultaneously. The gear 81 drives the noodle roller set in the third lowest layer to rotate by engaging a gear 84. The gear 82 drives the other noodle roller of the noodle roller set in the second lowest layer to rotate synchronously by engaging a gear 83. At the same time, gears 85, 87 disposed on the same drive shaft (shaft 5) together with the gear 84 rotate simultaneously. The gear 87 drives the noodle roller set in the forth lowest layer, which is the noodle roller set in the highest layer in this embodiment, to rotate. The gear 85 drives the other noodle roller in the noodle roller set in the third lowest layer to rotate synchronously by engaging a gear 86. A gear 89 disposed on the same drive shaft (shaft 7) together with a gear 88 drives the other noodle roller of the noodle roller set in the highest layer to rotate simultaneously by engaging a gear 90.
According to the description above, in the embodiment, the motor 8 drives the noodle rollers in the noodle roller set in the lowest layer by engaging the gear. The gears in the noodle roller set in the lowest layer drives a set of blades and the noodle roller set in the second lowest layer to rotate simultaneously by engaging the gears. In the multi-layer noodle roller sets, the noodle roller set in a lower layer successively drives the noodle roller set in a higher layer to rotate simultaneously by engaging of the gears, and in the noodle rollers in the same layer, the two gears used for driving the two noodle rollers are synchronized gears.
In order to ensure the results achieved when the noodle roller sets process the dough, it is required to limit the rolling rates of the multi-layer noodle roller sets, and the following conclusion is obtained through many tests and calculations: in the multi-layer noodle roller sets, when the rolling rate (nm) of the noodle roller set in each layer in order from bottom to top satisfies the following equation, formula 2, better rolling results are obtained:

i=nm/n(m+1), 2≧i>1.6  Formula 2:

i increases with the increase of m, the relationship between the rotation rate (nc) of the blades, and the rolling rate (n1) of the noodle roller set in the lowest layer satisfies the following equation, formula 3:

k=nc/n1, 1.6>k>1.3  Formula 3:

The structure of the noodle forming mechanism in the first embodiment is described in detail above. The noodle forming mechanism is suitable for processing spherical dough after the kneading and fermenting process, particularly an irregular ellipsoidal shape. The noodle forming mechanism does not particularly limit the shapes of the dough and has great adaptability to irregular shapes. The thick dough entering the noodle forming mechanism becomes thinner from top to bottom after the successive rolling and pressing process of the multi-layer noodle roller set, and then is directly sliced into noodles during the slicing process of the noodle forming blades, so as to improve the noodle production efficiency. Moreover, in the noodle forming mechanism, by designing the gaps, the rates and the coordination of the multi-layer noodle roller sets, the rolling results of the rolling mechanism are comparable to the hand rolling process, so as to generate enough gluten and realize using machines to simulate the hand rolling process of hand rolled noodles.
Using the noodle forming mechanism to produce noodles not only saves manpower and improves the processing rate, but also maintains the taste and quality of hand rolled noodles. In addition, the noodle forming mechanism directly makes noodles from dough, so as to eliminate scattering dry flour during the noodle production process, avoiding the inconvenience of replacing the water constantly, and saves flour, water, and energy.
