Description

Technical Field

[0001] The invention belongs to the technical field of meat product processing, and in particular relates to a tumbling and kneading device for efficient pickling of pork. Background Art

[0002] The main reasons for tumbling pork when marinating include accelerating the penetration and color development of the marinade, improving the extraction and distribution of salt-soluble proteins, and improving the tenderness and yield of the meat. Tumbling is a physical treatment process that uses mechanical impact to cause the meat pieces to collide, rub and squeeze each other, thereby reducing the mechanical strength of muscle fibers and connective tissues, destroying the cell structure, and promoting the uniform distribution and penetration of the marinade. Specifically, the functions and purposes of tumbling include: 1) Accelerate the penetration and color development of the marinade: Tumbling and kneading uses the principle of physical impact to accelerate the penetration of the marinade through the falling, rubbing and destruction of meat tissue. This treatment can also make the injected marinade evenly distributed in the meat, shorten the marinating time, and improve the tenderness and yield of the product.

[0003] 2) Extraction of salt-soluble proteins: During the tumbling process, the friction, impact and squeezing between the meat pieces cause the salt-soluble proteins to precipitate from the cells. These proteins absorb water, starch and other components to form a sticky substance, which improves the adhesion and water retention of the meat.

[0004] 3) Improve the tenderness of meat: Tumbling and kneading damages muscle cells, releases a large amount of calcium ions, activates calcium-activated neutral proteases, and degrades cytoskeletal proteins, thereby improving the tenderness of meat. In addition, tumbling and kneading breaks muscle fibers and releases proteins to the surface of muscle tissue, achieving the purpose of water retention, further improving the tenderness and water holding capacity of meat.

[0005] 4) Reduce cooking loss: Tumbling accelerates the combination of anions in the marinade with cations in the muscle, releasing more negatively charged carboxyl ends of polypeptide chains, providing more water storage space, reducing protein oxidation and conformational changes, and giving meat products good sensory properties.

[0006] In the prior art, when marinating pork, a tumbling and kneading device is required to tumble and knead the pork so that the marinating liquid can penetrate into the pork. For example, Chinese Patent Publication No. CN211268377U discloses a pork tumbling and kneading marinating device. The pork tumbling and kneading marinating device comprises: a support frame and a vacuum device; a tumbling and kneading cylinder, which is arranged on the top of the support frame through a fixing member, and a sealing cover is arranged on the left side of the tumbling and kneading cylinder; two sterilization components, which are respectively arranged on the left and right sides of the inner wall of the tumbling and kneading cylinder; a massage component, which is fixed on the inner wall of the tumbling and kneading cylinder; and a driving component, which is fixedly installed on the right side of the top of the support frame and is in transmission connection with the right end of the tumbling and kneading cylinder. The pork tumbling and kneading marinating device provided by the utility model has an elastic cavity arranged inside the elastic layer, and a semicircular arc rubber block is arranged inside the elastic cavity, and the convex sides of the two semicircular arc rubber blocks are fixedly connected, thereby greatly improving the elasticity of the elastic layer, so that when the pork falls onto the elastic layer again, it can bounce upward better and then fall down, undergoing a secondary impact treatment, thereby improving the marinating effect.

[0007] The pork tumbling and kneading equipment in the above-mentioned prior art tumbles and kneads the pork by rotating the tumbling and kneading drum so that the massage component in the tumbling and kneading drum kneads the pork. However, during the pork pickling process, workers often pour a plurality of semi-finished pork products into the tumbling and kneading drum together, which will cause the semi-finished pork products to accumulate in the tumbling and kneading drum, so that some of the semi-finished pork products may not be able to contact the massage component, resulting in uneven tumbling of the pork. In addition, in the prior art, the pork falls from a high place in the inner cavity of the tumbling and kneading drum as the tumbling and kneading drum rotates, so that the pork contacts the massage component, thereby achieving tumbling. This method does not have enough kneading force on the pork, resulting in a poor tumbling effect. Therefore, the present application proposes a tumbling and kneading device for pickling pork that can generate sufficient kneading force on the pork to meet actual use needs. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a tumbling and kneading device for efficient pickling of pork.

[0009] The technical solution adopted to solve the above technical problems is: a tumbling and kneading device for efficient pickling of pork, comprising a bracket, and also comprising: A tumbling bin installed on the top of the bracket, the top of the tumbling bin is open; A plurality of active kneading rollers are vertically rotatably connected to the inner wall of the kneading bin, and a rotation driving mechanism is provided at the bottom of the kneading bin, and the rotation driving mechanism is used to drive the plurality of active kneading rollers to rotate synchronously; A fixed seat coaxially connected to the bottom wall of the inner cavity of the tumbling and kneading bin, a plurality of driven kneading rollers are arranged on the periphery of the fixed seat, and an annular tumbling and kneading channel is formed between the plurality of active kneading rollers and the plurality of driven kneading rollers; A mounting mechanism is arranged on the top of the tumbling bin, and is used to hang the pork, and when the rotating drive mechanism is actuated, the pork is driven to move in a circular track in the tumbling channel.

[0010] Through the above technical scheme, the pork is suspended by the mounting mechanism, so that the pork can enter the tumbling channel when the cover plate moves down, and the active kneading roller is driven by the rotating drive mechanism to rotate synchronously, and the mounting mechanism is rotated, so that the pork can rotate along a circular trajectory in the tumbling channel. During the rotation, the active kneading roller and the driven kneading roller can knead the pork. Compared with the tumbling and kneading method in the prior art, on the one hand, the phenomenon of pork accumulation is avoided, thereby preventing the phenomenon that some pork is not fully tumbled. On the other hand, during the movement of the pork in the tumbling and kneading channel, multiple active kneading rollers and driven kneading rollers generate extrusion forces in different directions on the pork, so that the tumbling and kneading effect is better.

[0011] Furthermore, a plurality of kneading convex strips are fixedly connected to the peripheries of the active kneading roller and the driven kneading roller.

[0012] Through the above technical scheme, kneading convex strips are provided so that when the kneading convex strips contact the pork, they can be squeezed into the pork, thereby increasing the local squeezing force on the pork, so that the muscle fibers of the pork can be squeezed and broken, and then the pickling liquid can effectively and quickly penetrate into the pork, thereby improving the pickling efficiency of the pork.

[0013] Furthermore, the outer contour of the kneading convex strips is spiral and is evenly distributed on the periphery of the active kneading roller and the driven kneading roller.

[0014] Through the above technical solution, the kneading convex strips are spiral-shaped, so that the area where the kneading convex strips can squeeze the pork muscle fibers is increased, thereby reducing the blind areas or dead angles of kneading.

[0015] Furthermore, a plurality of ear blocks are fixedly connected to the inner cavity side wall of the tumbling and kneading bin in an axial array along the tumbling and kneading bin, a first rotating shaft is vertically rotatably connected to the ear blocks, and the active kneading roller is fixedly sleeved on the periphery of the first rotating shaft.

[0016] Through the above technical solution, the first rotating shaft is rotatably connected to the ear block, so that the active kneading roller is vertically rotatably connected to the side wall of the inner cavity of the rolling and kneading bin.

[0017] Furthermore, the rotation drive mechanism includes a gear fixedly sleeved on one end of the first rotating shaft passing through the bottom of the tumbling bin, the bracket is provided with a motor mounting frame, a reduction motor is vertically mounted on the motor mounting frame, the output shaft of the reduction motor is connected to the rotating shaft through a coupling drive, the periphery of the rotating shaft is fixedly sleeved with an annular rack, and the annular rack is externally meshed with the plurality of gears.

[0018] Through the above technical scheme, the reduction motor is started, and the output shaft of the reduction motor rotates, which in turn drives the coupling to rotate, and then drives the rotating shaft to rotate. When the rotating shaft rotates, it synchronously drives the annular rack to rotate, and then through the meshing of the annular rack and the gear, the gear can be rotated. At the same time, when the gear rotates, it will drive the first rotating shaft to rotate, so that the active kneading roller is rotated. In addition, the nominal diameter of the annular rack is much larger than the nominal diameter of the gear, so that the angular velocity of the active kneading roller is greater than the angular velocity of the pork in the rolling and kneading channel. In this way, the active kneading roller can produce a phenomenon similar to slipping with the surface of the pork, and combined with the kneading convex strips, it can produce a massage effect on the surface of the pork, so that the pickling liquid can quickly and effectively penetrate into the pork.

[0019] Furthermore, the mounting mechanism includes a lifting assembly installed on the outer wall of the tumbling bin, the output end of the lifting assembly is drivingly connected to a floating frame, a cover plate is rotatably connected to the floating frame, a plurality of hooks are fixedly connected to a downward side of the cover plate, the hooks are located directly above the tumbling channel, the cover plate is provided with a spline hole for the rotating shaft to pass freely, and the periphery of the rotating shaft is spline-connected to the spline hole.

[0020] Through the above technical solution, the rotating shaft and the spline hole on the cover plate are spline-connected, so that when the rotating shaft rotates, it can drive the cover plate to rotate synchronously, and then drive the pork to rotate in the tumbling channel.

[0021] Furthermore, the lifting assembly includes cylinder support plates respectively fixed to both sides of the tumbling bin, a cylinder is vertically installed at the bottom of the cylinder support plate, and a cylinder rod of the cylinder penetrates the cylinder support plate and is connected to the floating frame.

[0022] Through the above technical solution, the cylinder rod of the cylinder is extended or shortened, thereby driving the floating rack to move up or down accordingly, so that the floating rack can drive the pork to move up and down, so that the pork can be placed in the tumbling channel, and then the tumbling operation of the pork can be carried out.

[0023] Furthermore, a plurality of arms are fixedly connected to the periphery of the fixed seat from top to bottom, a sliding block is horizontally slidably connected to the arm, two corresponding sliding blocks are connected to a second rotating shaft for common rotation, the driven kneading roller is fixedly sleeved on the periphery of the second rotating shaft, and an extrusion assembly for driving the sliding block to move horizontally back and forth is provided on the fixed seat.

[0024] Through the above technical solution, when the rotating shaft rotates, the extrusion component drives the sliding block to reciprocate horizontally, so that the driven kneading roller reciprocates horizontally in the direction of the active kneading roller, thereby increasing the extrusion force of the driven kneading roller on the pork, thereby achieving a better rolling and kneading effect on the pork.

[0025] Furthermore, a slot is provided on the inner side wall of the hollowed-out portion of the support arm, and the end of the sliding block is engaged in the slot and can slide freely in the radial direction of the fixing seat.

[0026] Through the above technical solution, the sliding block slides in the card slot, so that the sliding block is horizontally slidably connected to the support arm.

[0027] Furthermore, the extrusion assembly includes a driving rod fixedly connected to the surface of the sliding block, the end of the driving rod away from the sliding block penetrates into the fixed seat and slides freely, the rotating shaft coaxially penetrates the fixed seat and rotates freely, the portion of the rotating shaft penetrating into the fixed seat is fixedly sleeved with two mounting sleeves from top to bottom, the periphery of the mounting sleeve is fixedly sleeved with a rotating part, the periphery of the rotating part is fixedly sleeved with a plurality of protrusions in an axial array, the end of the driving rod penetrating into the fixed seat is rotatably connected to a roller, the roller is alternately in rolling contact with the protrusion and the periphery of the rotating part, the end of the driving rod penetrating from the fixed seat is fixedly sleeved with a stop ring, the periphery of the driving rod is sleeved with a tension spring, the two ends of the tension spring are respectively fixed to the end face of the stop ring and the periphery of the fixed seat.

[0028] Through the above technical scheme, when the rotating shaft rotates, it will synchronously drive the mounting sleeve to rotate. When the mounting sleeve rotates, it will drive the rotating part to rotate. At the same time, because the tension spring has a pulling force on the stop ring toward the inner side of the fixed seat, when the rotating part rotates, the roller can alternately roll on the periphery of the rotating part and the surface of the protrusion. When the roller rolls from the periphery of the rotating part to the surface of the protrusion, the driving roller and the driving rod will move toward the outer side of the fixed seat, thereby driving the sliding block to move toward the radial outer side of the fixed seat, so that the driven kneading roller moves toward the active kneading roller, thereby reducing the gap in the rolling and kneading channels between the active kneading roller and the driven kneading roller, thereby increasing the degree of squeezing of the pork by the active kneading roller and the driven kneading roller. At the same time, since the squeezing force on the pork is increased intermittently, the surface of the pork will not be damaged.

[0029] The beneficial effects of the present invention are as follows: (1) In the present invention, the pork is suspended by a mounting mechanism, so that the pork can enter the tumbling channel when the cover plate moves down, and the active kneading roller is driven by the rotating drive mechanism to rotate synchronously, and the mounting mechanism is rotated, so that the pork can rotate along a circular trajectory in the tumbling channel. During the rotation process, the active kneading roller and the driven kneading roller can knead the pork. Compared with the tumbling method in the prior art, on the one hand, the pork accumulation phenomenon is avoided, thereby preventing the phenomenon that part of the pork is not fully tumbled. On the other hand, during the movement of the pork in the tumbling channel, multiple active kneading rollers and driven kneading rollers generate extrusion forces in different directions on the pork, so that the tumbling effect is better; (2) In the present invention, the output shaft of the reduction motor is started to rotate, which in turn drives the coupling to rotate, and then drives the rotating shaft to rotate. When the rotating shaft rotates, it synchronously drives the annular rack to rotate, and then through the meshing of the annular rack and the gear, the gear can be rotated. At the same time, when the gear rotates, it will drive the first rotating shaft to rotate, so that the active kneading roller rotates. In addition, the nominal diameter of the annular rack is much larger than the nominal diameter of the gear, so that the angular velocity of the active kneading roller is greater than the angular velocity of the pork in the rolling and kneading channel. In this way, the active kneading roller can produce a phenomenon similar to slipping with the surface of the pork, and combined with the kneading convex strips, it can produce a massage effect on the surface of the pork, so that the pickling liquid can quickly and effectively penetrate into the pork; (3) In the present invention, when the rotating shaft rotates, it will synchronously drive the mounting sleeve to rotate. When the mounting sleeve rotates, it will drive the rotating part to rotate. At the same time, the tension spring has a pulling force on the stop ring toward the inner side of the fixed seat. Therefore, when the rotating part rotates, the roller can alternately roll on the periphery of the rotating part and the surface of the protrusion. When the roller rolls from the periphery of the rotating part to the surface of the protrusion, it drives the roller and the driving rod to move toward the outer side of the fixed seat, thereby driving the sliding block to move toward the radial outer side of the fixed seat, so that the driven kneading roller moves toward the active kneading roller, thereby reducing the gap in the kneading channel between the active kneading roller and the driven kneading roller, thereby increasing the degree of squeezing of the pork by the active kneading roller and the driven kneading roller. At the same time, since the squeezing force on the pork is increased intermittently, the surface of the pork will not be damaged. BRIEF DESCRIPTION OF THE DRAWINGS

The number and position of the active kneading roller 8 and the driven kneading roller 3 correspond to each other. A rolling and kneading channel is formed between the multiple active kneading rollers 8 and the driven kneading rollers 3. The rolling and kneading channel is annular, and the spacing between adjacent active kneading rollers 8 and driven kneading rollers 3 is slightly smaller than the width of the semi-finished pork product. The periphery of the active kneading roller 8 and the driven kneading roller 3 is fixedly connected with a plurality of kneading convex strips 15, and the outer contour of the kneading convex strips 15 is spiral and evenly distributed on the periphery of the active kneading roller 8 and the driven kneading roller 3; The outer walls of the two opposite sides of the tumbling and kneading bin 9 are fixedly connected with cylinder support plates, and the bottom of the cylinder support plate is vertically installed with cylinders 2. The cylinder rods of the two cylinders 2 penetrate the cylinder support plate, and the ends of the cylinder rods of the two cylinders 2 are commonly connected with a floating frame 6. When the cylinder rods of the cylinders 2 are extended or shortened, the floating frame 6 will be driven to move up or down accordingly. An annular mounting groove is provided in the hollow part in the middle of the floating frame 6, and a cover plate 5 is coaxially engaged in the mounting groove. The cover plate 5 can freely rotate around the axial direction of the tumbling and kneading bin 9 in the mounting groove. In addition, the positive projection area of ​​the cover plate 5 and the floating frame 6 covers the mouth of the tumbling and kneading bin 9, so that when the cylinder rods of the cylinders 2 are shortened and drive the floating frame 6 to move downward, the cover plate 5 and the floating frame 6 can seal the mouth of the tumbling and kneading bin 9; A gear 13 is fixedly sleeved on one end of the first rotating shaft 17 passing through the bottom of the tumbling bin 9, a motor mounting frame is provided on the bracket 10, a reduction motor 1 is vertically installed on the motor mounting frame, the reduction motor 1 is externally connected to an external power supply, and then the external power supply powers the reduction motor 1, the output shaft of the reduction motor 1 is connected to the rotating shaft 7 through a coupling drive, the periphery of the rotating shaft 7 is fixedly sleeved with an annular rack 12, and the annular rack 12 is externally meshed with multiple gears 13. When the reduction motor 1 is started, the output shaft of the reduction motor 1 rotates, thereby driving the coupling to rotate, driving the rotating shaft 7 to rotate, and the rotating shaft When the cover plate 5 rotates, the annular rack 12 is synchronously driven to rotate, and then the annular rack 12 and the gear 13 are meshed, so that the gear 13 can rotate. At the same time, when the gear 13 rotates, it will drive the first rotating shaft 17 to rotate, so that the active kneading roller 8 rotates. A plurality of hooks 11 are fixedly connected to the downward side of the cover plate 5. The hooks 11 are located just above the rolling and kneading channel. The cover plate 5 is provided with a spline hole for the rotating shaft 7 to pass freely. The periphery of the rotating shaft 7 is spline-connected with the spline hole. In addition, an avoidance hole is provided on the end surface of the fixed seat 4 for the rotating shaft 7 to pass freely. The rotating shaft 7 can rotate freely in the avoidance hole. A driving rod 21 is fixedly connected to the surface of the sliding block 16 horizontally, and one end of the driving rod 21 away from the sliding block 16 penetrates into the fixed seat 4 and slides freely. The portion where the rotating shaft 7 penetrates into the fixed seat 4 is fixedly sleeved with two mounting sleeves 22 from top to bottom, and the two mounting sleeves 22 correspond to the axial ends of the driven kneading roller 3 respectively. The periphery of the mounting sleeve 22 is fixedly sleeved with a rotating portion 23, and the periphery of the rotating portion 23 is fixedly connected with a plurality of protrusions 24 in an axial array. The end of the driving rod 21 that penetrates into the fixed seat 4 is rotatably connected with a roller 25, and the roller 25 is in rolling contact with the protrusions 24 and the periphery of the rotating portion 23 alternately. A stop ring 19 is fixedly sleeved on the end of the driving rod 21 that penetrates out of the fixed seat 4, and a tension spring 18 is wound around the periphery of the driving rod 21. The two ends of the tension spring 18 are respectively fixed to the end face of the stop ring 19 and the periphery of the fixed seat 4. In the initial state, the tension spring 18 has a radially inward force on the stop ring 19 toward the fixed seat 4. The pulling force on the side makes the roller 25 abut against the periphery of the rotating part 23 or the surface of the protrusion 24. When the rotating shaft 7 rotates, it will synchronously drive the mounting sleeve 22 to rotate. When the mounting sleeve 22 rotates, it will drive the rotating part 23 to rotate. At the same time, since the tension spring 18 has a pulling force on the stop ring 19 toward the inner side of the fixed seat 4, when the rotating part 23 rotates, the roller 25 can alternately roll on the periphery of the rotating part 23 and the surface of the protrusion 24. When the roller 25 rolls from the periphery of the rotating part 23 to the surface of the protrusion 24, the roller 25 is squeezed by the protrusion 24, and then the driving roller 25 and the driving rod 21 are moved toward the outer side of the fixed seat 4, and then the sliding block 16 is driven to move toward the radial outer side of the fixed seat 4, so that the driven kneading roller 3 moves in the direction close to the active kneading roller 8, thereby reducing the gap in the rolling and kneading channel between the active kneading roller 8 and the driven kneading roller 3.

[0034] The working principle of this embodiment is as follows: First, pour a proper amount of pickling liquid into the tumbling bin 9, then hang the semi-finished pork product to be tumbled on the hook 11, and then start the cylinder 2, the cylinder rod of the cylinder 2 is shortened, and then the floating frame 6 is driven to move downward. When the floating frame 6 moves downward, it will synchronously drive the cover plate 5 to move downward. Since the spline hole on the cover plate 5 and the rotating shaft 7 are spline-connected, the cover plate 5 can slide downward on the periphery of the rotating shaft 7. After sliding into place, the semi-finished pork product will enter the tumbling channel surrounded by the active rubbing roller 8 and the driven rubbing roller 3, and since the positive projection area of ​​the cover plate 5 and the floating frame 6 covers the mouth of the tumbling bin 9, when the cylinder rod of the cylinder 2 is shortened and drives the floating frame 6 to move downward, the cover plate 5 and the floating frame 6 can seal the mouth of the tumbling bin 9, so that the pickling liquid in the tumbling bin 9 will not splash to the outside of the tumbling bin 9; Then, the external power supply is turned on to start the reduction motor 1. When the reduction motor 1 is started, the output shaft of the reduction motor 1 rotates, thereby driving the coupling to rotate, driving the rotating shaft 7 to rotate, and when the rotating shaft 7 rotates, the annular rack 12 is synchronously driven to rotate, and then the annular rack 12 and the gear 13 are meshed, so that the gear 13 can be rotated. At the same time, when the gear 13 rotates, it will drive the first rotating shaft 17 to rotate, so that the active kneading roller 8 rotates, so that the semi-finished pork product rotates in a circular motion trajectory in the tumbling and kneading channel; When the semi-finished pork product enters between the adjacent active kneading roller 8 and the driven kneading roller 3, since the active kneading roller 8 is in a rotating state, when the active kneading roller 8 contacts the surface of the semi-finished pork product, the semi-finished pork product can be moved between the active kneading roller 8 and the driven kneading roller 3, and the kneading convex strips 15 on the periphery of the active kneading roller 8 have an extrusion force on the semi-finished pork product, and thus the semi-finished pork product can be bitten between the active kneading roller 8 and the driven kneading roller 3, and the active kneading roller 8 and the driven kneading roller 3 produce a kneading effect on the semi-finished pork product. At the same time, since the kneading convex strips 15 are provided, when the kneading convex strips 15 contact the semi-finished pork product, the kneading convex strips 15 can be squeezed into the semi-finished pork product, and the local extrusion force on the semi-finished pork product is increased, so that the muscle fibers of the semi-finished pork product can be squeezed and broken, and then the pickling liquid can effectively and quickly penetrate into the pork, thereby improving the pickling efficiency of the pork; Since the periphery of the rotating shaft 7 is spline-connected with the spline hole of the cover plate 5, the rotating shaft 7 will synchronously drive the cover plate 5 to rotate when it rotates. When the cover plate 5 rotates, the semi-finished pork product will rotate along a circular trajectory in the tumbling channel. During the rotation process, the semi-finished pork product will be squeezed and tumbled by multiple active tumbling rollers 8 and driven tumbling rollers 3, so that the semi-finished pork product can be tumbled multiple times. In addition, when the rotating shaft 7 rotates, it synchronously drives the mounting sleeve 22 to rotate. When the mounting sleeve 22 rotates, it drives the rotating part 23 to rotate. At the same time, because the tension spring 18 has a pulling force on the stop ring 19 toward the inner side of the fixing seat 4, the semi-finished pork product can be rolled and kneaded multiple times. When the rotating part 23 rotates, the roller 25 can alternately roll on the periphery of the rotating part 23 and the surface of the protrusion 24. When the roller 25 rolls from the periphery of the rotating part 23 to the surface of the protrusion 24, the roller 25 is squeezed by the protrusion 24, and then the driving roller 25 and the driving rod 21 move toward the outside of the fixed seat 4, and then the sliding block 16 moves toward the radial outside of the fixed seat 4, so that the driven kneading roller 3 moves toward the active kneading roller 8, and then the gap between the active kneading roller 8 and the driven kneading roller 3 in the rolling and kneading channel becomes smaller, so that the semi-finished pork product is squeezed by the active kneading roller 8 and the driven kneading roller 3 with greater force; When the roller 25 rolls from the surface of the protrusion 24 to the periphery of the rotating portion 23, it is pulled by the tension spring 18 on the stop ring 19, so that the driving rod 21 can move toward the radial inner side of the fixed seat 4, and the sliding block 16 can move toward the radial inner side of the fixed seat 4, thereby reducing the gap in the rolling and kneading channel between the active kneading roller 8 and the driven kneading roller 3. At the same time, since the squeezing force on the pork is increased intermittently, the surface of the pork will not be damaged. In addition, when the semi-finished pork product rotates along a circular trajectory in the rolling and kneading channel, the active kneading roller 8 and the driven kneading roller 3 can squeeze the semi-finished pork product. The semi-finished pork is kneaded and pressed. Compared with the tumbling and kneading method in the prior art, on the one hand, it avoids the accumulation of semi-finished pork products, thereby preventing the phenomenon that some semi-finished pork products are not fully tumbled and kneaded. On the other hand, during the movement of the semi-finished pork products in the tumbling and kneading channel, multiple active kneading rollers 8 and driven kneading rollers 3 generate extrusion forces in different directions on the semi-finished pork products, so that the tumbling and kneading effect is better. After tumbling and kneading is completed, the cylinder 2 is started again, and the cylinder rod of the cylinder 2 is extended and drives the cover plate 5 to move upward, so that the staff can take the semi-finished pork products that have been tumbled and kneaded off the hook 11, thereby completing a tumbling and kneading operation.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
