The other end of the contour plate 71 moves in the concave-convex groove 73 through the ball 74. As the mounting rod 3 rotates, the mounting rod 3 drives the contour plate 71 to rotate through the cylinder 7, so that the ball 74 moves along the path of the concave-convex groove 73, thereby moving the contour plate 71 back and forth toward the center of the cover plate 14, thereby increasing the cutting direction of the blade 72, which is beneficial to improving the working efficiency of the blade 72 in cutting strip meat.

[0048] It should be noted that the present invention is a processing device and a processing method for processing pork dumplings, such as Figure 1-6 As shown, when in use, the inside of the meat grinder roller 2 is first ventilated, the plug 32 is rotated, the front port of the mounting rod 3 is connected to the hose, and then the air pump delivers cold gas to the inside of the No. 1 cavity 21 and the No. 2 cavity 31. The cold gas reduces the temperature of the inner and outer surfaces of the mounting rod 3 and the meat grinder tube, so that the meat is minced in a low temperature environment, reducing the impact of the temperature rise caused by the operation of the meat grinder roller 2 on the meat, reducing the loss of meat juice, and helping to improve the production quality and production efficiency of meat fillings; at the same time, after each air pump air delivery, it will be back-drawn to extract excess cold gas until the inner side of the rubber layer 25 is tightly attached to the surface of the meat grinder roller 2, so that the spiral pitch depth between the No. 2 threaded blocks 23 remains unchanged;

[0049] After the ventilation is completed, the raw meat material is placed in the feed channel 11, and the raw meat material moves along the feed channel 11 to the transition channel 12, so that the raw meat material contacts the meat grinding roller 2. At the same time, the driving motor 15 drives the meat grinding roller 2 to rotate inside the transition channel 12 and the meat grinding cylinder 13 through the connecting rod 4, and the pad knife 24 on the rear side of the meat grinding roller 2 performs preliminary processing on the raw meat material, so that the volume of the raw meat material is reduced and it falls into the spiral pitch of the No. 2 thread block 23, and then the preliminarily processed meat material moves to the front side of the meat grinding roller 2, the pad knife 24 cooperates with the No. 1 thread block 16, and the No. 1 thread block 16 performs secondary processing on the meat material within the spiral pitch of the No. 2 thread block 23, and then under the push and extrusion of the meat grinding roller 2, the secondary processed meat material will pass through the pre-cutting plate 33, the cross knife 34 and the meat paste plate 35 in turn, and finally the meat material is squeezed out from the round hole on the meat paste plate 35, thereby preparing strip-shaped meat material;

[0050] Before processing the next raw meat material, the air pump delivers cold air to the No. 1 cavity 21 and the No. 2 cavity 31 again. The cold air causes the rubber layer 25 to expand outward, and the surface of the rubber layer 25 is flush with the outermost edge of the pad knife 24, thereby shortening the spiral pitch depth of the No. 2 threaded block 23, so that the meat material is separated from the spiral pitch. Then the telescopic cylinder 41 is started, and the telescopic cylinder 41 pushes the moving ring 42 to move, so that the inner side of the moving ring 42 moves along the outer surface of the rubber layer, and the outer side of the moving ring 42 first moves along the inner wall of the transition channel 12, and then along the mincing drum 1 3, so that the moving ring 42 pushes the meat remaining on the outer surface of the rubber layer, the inner wall of the transition channel 12 and the inner wall of the meat grinder 13 to the rear side of the pre-cut plate 33, and the remaining meat is processed together with the next raw meat, which is beneficial to reduce the meat remaining in the spiral pitch on the meat grinder 2 and the waste of processed raw meat. Then, the air pump draws air, so that the inner side of the rubber layer 25 is in close contact with the surface of the meat grinder 2, and cold gas is stored in the meat grinder 2 and the mounting rod 3, so that the next raw meat is in a low temperature environment.

[0051] A method for processing pork dumplings comprises the following steps:

[0052] S1: Wash the raw materials and remove the unnecessary parts. Pour the vegetables into the basin-type vegetable cutter for mincing. Put the minced vegetables into the pressing machine to press out the excess water. Before mincing, use the air pump to deliver cold air into the first cavity 21 and the second cavity 31 to keep the surface of the mounting rod 3 and the mincing roller 2 at a low temperature.

[0053] S2: Pour the raw meat into the processing box 1 through the feeding channel, and make the meat grinder 2 perform primary and secondary processing on the raw meat. At the same time, as the meat grinder 2 pushes, the meat passes through the pre-cutting plate 33, the cross knife 34 and the meat paste plate 35 in sequence, so as to be prepared into strip-shaped meat;

[0054] S3: cold air is injected again to expand the rubber layer 25 and remove the remaining meat from the spiral pitch, and the meat is moved to the rear side of the pre-cut plate 33 under the push of the moving ring 42. At the same time, the strip meat and chopped vegetables are poured into the mixer, and seasonings are added to mix into meat filling, and the flour is poured into the noodle making machine and pressed into dough through a mold;

[0055] S4: The meat filling is poured directly into the middle of the dough through a conveying tube, and then the dumplings are formed and sealed through a mold. The wrapped dumplings are frozen on a conveyor belt at -40℃, and then sealed and inspected.
