Abstract
Description
Technical Field
[0001] This application relates to the field of food processing equipment technology, and in particular to a two-color dumpling processing equipment. Background Technology
[0002] As consumers increasingly demand diversity in the appearance and taste of food, two-tone dumplings, with their unique visual appeal and rich flavor profile, have gradually become a popular product in the market. Currently, the processing of two-tone dumpling wrappers is mostly done manually or with semi-automated equipment, which presents the following problems: Manual processing requires rolling out two different colored doughs separately and then manually combining them. This not only results in extremely low production efficiency but also makes it difficult to maintain consistent dough thickness and bonding precision, leading to problems such as dough cracking and uneven layers, which cannot meet the needs of large-scale production. Most semi-automated equipment can achieve continuous processing of single-color doughs. If two-color doughs are to be made, additional conveying and bonding mechanisms are required. Furthermore, the relative positions of the two-color doughs are prone to deviation during dumpling dough production, resulting in dumpling doughs that do not achieve the desired effect. Utility Model Content

Detailed Implementation
[0013] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0014] This application discloses a two-color dumpling processing device. For example... Figure 1 and 2 As shown, the machine includes a frame 1. A first pressing roller 2, which is screwed onto the frame 1 to extrude a first thick dough strip into a first sheet, is a prior art material. A short feed conveyor belt 3, which is screwed onto the frame 1 to transport the first thick dough strip to the first pressing roller 2, is also screwed onto the frame 1. A support frame, fixed to the ground, is provided on one side of the frame 1. A second pressing roller 4, which is screwed onto the support frame to extrude a second colored thick dough strip into a second sheet, is also screwed onto the support frame to transport the second colored thick dough strip to the second pressing roller 4. The second pressing roller 4 and the second conveyor roller 5 are arranged in pairs, with at least one pair provided, and other colors can be added. The frame 1 is equipped with a third pressing roller 6 for combining the first dough sheet and the second dough sheet into a composite dough sheet. The frame 1 is screwed with a fourth pressing roller 7 for rolling the composite dough sheet into dumpling dough sheets. A third conveyor belt 8 for moving the composite dough sheet is provided between the third pressing roller 6 and the fourth pressing roller 7. A fourth conveyor belt 9 for conveying dumpling dough sheets to the dumpling forming machine is provided on the frame 1 near the fourth pressing roller 7. The frame 1 is also equipped with a return conveyor belt 10 for recycling the unused portion of the first dough sheet. The return conveyor belt 10 is prior art.
[0015] In one embodiment, according to the appendix Figure 3 and 4As shown, a first conveyor belt 11 for moving the second dough sheet is connected to the support frame and the machine frame 1 by screws. A second conveyor belt 12 is fixed to the machine frame 1 by screws. When the second conveyor belt 12 moves the second dough sheet past the first pressing roller 2, the first dough sheet will cover the second dough sheet and move to the third pressing roller 6 under the action of the second conveyor belt 12. The second dough sheet includes a dough strip. A cutter is provided on the first conveyor belt 11. The dough strip includes edge dough strips located at both ends and a middle dough strip located between the two edge dough strips. The cutter includes two identical brackets 13 fixed to the frame of the first conveyor belt 11 by screws. A knife holder 14 is rotatably connected to each of the two brackets 13. The knife holder 14 has a "U" shape. A dividing disc 15 with a set interval is rotatably connected to the end of each knife holder 14 away from the bracket 13. When the second colored thick strip passes through the second pressing roller 4 and then the cutter, it will be divided into edge strips and middle strips of a set width. The number of middle strips can be zero or more, which can be adjusted by changing the number of dividing discs 15. After being divided by the dividing discs 15, the second strips located at both ends and outside the dividing discs 15 fall off the first conveyor belt 11 under manual guidance and their own gravity, and can be recycled and placed back into the second colored thick strip position. It can also be ensured, according to processing requirements, that there is no excess surface outside the dividing discs 15 after the second colored thick strip is pressed by the second pressing roller 4. Excess surface can also be guided by manual traction to the second conveyor roller 5 and adhered to the second colored thick strip. Under the action of the second conveyor roller 5, any subsequent excess surface will continuously accumulate on the second colored thick strip. A separation mechanism extending to the surface of the second surface conveyor belt 12 is provided on the frame 1. The separation mechanism includes a base frame 16 fixed to the frame 1 with screws. Multiple sets of identical rotating rollers are provided on the base frame 16. The rotating roller sets are arranged along the length of the second surface conveyor belt 12. When the edge surface belt and the middle surface belt pass through the rotating roller sets, the edge surface belt and the middle surface belt will be separated by a set distance. The rotating roller sets include multiple guide rollers 17 arranged in sequence and rotatably connected to the base frame 16. The first surface conveyor belt 11 and the second surface conveyor belt 12 can be an integral structure.
[0016] The implementation principle of the two-color dumpling processing equipment in this application embodiment is as follows: Raw material preparation and conveying: Two different colored thick strips are used as the first thick strip and the second colored thick strip, respectively; after the equipment is started, the feed short conveyor belt 3 conveys the first thick strip to the first pressing roller 2, and the second conveyor roller 5 conveys the second colored thick strip to the second pressing roller 4. Single-sided extrusion molding: The first pressing roller 2 extrudes the first thick strip and rolls it into a first sheet of a set thickness; at the same time, the second pressing roller 4 extrudes the second colored thick strip and rolls it into a second sheet of a set thickness. Second sheet segmentation and conveying: The calendered second sheet moves under the drive of the first sheet conveyor belt 11. When it passes the cutter on the first sheet conveyor belt 11, the segmenting disc 15 in the cutter segments the second sheet into sheet strips of a set width, including edge sheet strips and middle sheet strips. The segmented sheet strips continue to move with the first sheet conveyor belt 11 to the second sheet conveyor belt 12, and are then conveyed towards the first pressing roller 2 under the drive of the second sheet conveyor belt 12. Surface separation and preliminary bonding: When the separated edge surface and middle surface pass through the separation mechanism, the roller group on the base frame 16, guided by the guide roller 17, separates the edge surface and middle surface by a set distance to ensure their relative position when in contact with the first surface skin; the first surface skin formed by the first pressing roller 2 covers the surface of the second surface skin conveyed by the second surface conveyor belt 12, and continues to move to the third pressing roller 6 under the drive of the second surface conveyor belt 12.
[0017] Composite dough sheet calendering: The third pressing roller 6 works to tightly bond the first dough sheet with the second dough sheet to form a composite dough sheet; the composite dough sheet moves to the fourth pressing roller 7 under the drive of the third conveyor belt 8, and the fourth pressing roller 7 further calenders the composite dough sheet to form a two-color dumpling dough sheet with a thickness that meets the requirements of dumpling processing.
[0018] Finished product conveying and excess dough recycling: The calendered two-color dumpling wrappers are directly conveyed to the dumpling forming machine by the fourth dough conveyor belt 9 for the subsequent dumpling wrapping process; the excess dough generated during the processing is recycled by the return dough conveyor belt 10 on the frame 1. The recycled excess dough is returned to the first thick dough belt position by the return dough conveyor belt 10 and participates in the dough processing again. After the second dough belt is divided by the dividing plate 15, the second dough belt located outside the dividing plates 15 at both ends can fall off the first dough conveyor belt 11 under its own weight. A recycling box is set on the frame 1 to receive it.
[0019] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
