[0001] The invention relates to the technical field of fresh meat processing, in particular to a fresh meat processing device and a process thereof for producing dietary fiber meat products. Background Art

[0002] Dietary fiber is mainly found in cereals, vegetables and fruits. It is a substance that cannot be digested by the human body but is very beneficial to health. Dietary fiber meat products are meat products with dietary fiber added, such as sausages. During the production process of dietary fiber meat products, fresh meat needs to be minced by a meat grinder. Most existing meat grinders use an auger to transport fresh meat to a mixing knife, which grinds the fresh meat, and finally the minced meat is squeezed out through the sieve holes on the sieve plate.

[0003] However, the agitator blades in existing meat grinders are generally fixedly connected to the auger, so that the frequency of the agitator blade cutting the fresh meat is relatively low, which reduces the efficiency of meat grinding, and the minced meat is squeezed out through the sieve holes on the sieve plate under the action of high-intensity pressure, which easily leads to some large pieces of fresh meat that are not completely broken into large strips being squeezed out from the sieve holes, thereby affecting the taste of dietary fiber meat products.

The fresh meat processing device for producing dietary fiber meat products according to claim 1, characterized in that: A hollow cap (28) is threadedly connected to one end of the outer wall of the conveying cylinder (2) away from the outer shell (1); the hollow cap (28) is located on a side of the circular screening plate (12) away from the conveying cylinder (2); a plurality of first plug rods (29) distributed in a circular array are fixedly connected to a side of the circular screening plate (12) close to the conveying cylinder (2); a plurality of first plug holes (30) distributed in a circular array are provided at one end of the conveying cylinder (2) close to the circular screening plate (12) corresponding to the first plug rods (29); the first plug rods (29) can be plugged into the first plug holes (30).

7. The fresh meat processing device for producing dietary fiber meat products according to claim 1, characterized in that: A plurality of second plugging rods (31) distributed in a circular array are fixedly connected to one end of the fixed cap sleeve (10) close to the circular screening plate (12); a plurality of second plugging holes (32) distributed in a circular array are provided in the middle of the circular screening plate (12) corresponding to the second plugging rods (31); and the second plugging rods (31) can be plugged into the second plugging holes (32).

8. A fresh meat processing process of a fresh meat processing device for producing dietary fiber meat products, applicable to a fresh meat processing device for producing dietary fiber meat products according to any one of claims 1 to 7, characterized in that: The process includes the following steps: Step 1: First, the driving mechanism is started, and the driving mechanism drives the first hollow auger (3) and the central rotating shaft (4) to rotate clockwise and counterclockwise respectively, and the central rotating shaft (4) drives the turbine blade (6), the arc-shaped centrifugal push plate (7) and the arc-shaped cutting knife (8) to rotate counterclockwise and drives the second hollow auger (9) and the scroll-shaped scraper (14) to rotate clockwise through the first transmission mechanism; Step 2: Pour the fresh meat into the hopper (15), and the fresh meat falls from the bottom of the hopper (15) into the conveying cylinder (2), and the rotating first hollow auger (3) conveys the fresh meat to the rear end; Step 3: Then, the rotating turbine blades (6) cut the fresh meat, and the cut minced meat is pushed toward the circular screening plate (12) through the gap between the conveying cylinder (2) and the inner sleeve (11), wherein the minced meat with smaller particles is discharged through the sieve holes (13) on the circular screening plate (12); Step 4: Then, the minced meat with larger particles is scraped off by the spiral scraper (14) and collected and concentrated by the second hollow auger (9) in the middle; Step 5: Then, the rotating second hollow auger (9) transports the large-particle minced meat to the arc-shaped centrifugal push plate (7) and the arc-shaped cutting knife (8) in cooperation with the inner sleeve (11); the arc-shaped cutting knife (8) further cuts the large-particle minced meat, and the arc-shaped centrifugal push plate (7) pushes the minced meat to the outer turbine blades (6); Step 6: Finally, the further cut minced meat is pushed by the rotating turbine blades (6) and discharged through the gap between the conveying cylinder (2) and the inner sleeve (11) and the sieve holes (13) on the circular screening plate (12).
