Description

Technical Field

[0001] This invention relates to the field of fish processing technology, and in particular to an automatic meat grinder that cuts meat evenly. Background Technology

[0002] A meat grinder is a kitchen or industrial device used to quickly cut and crush meat into uniform particles or mince. It is widely used in home cooking, food processing, and the catering industry. Its core function is to efficiently break down whole pieces of fresh, frozen, or bone-in meat into the desired minced state through high-speed rotating blades or an auger system, making it convenient for making foods such as minced meat, sausages, meatballs, and hamburger patties.

[0003] Because catfish have highly developed mucus glands on their bodies, a large amount of mucus protein remains on the surface of the cut fish meat, making its meat very sticky. When processing catfish meat chunks using existing meat grinders, there are two main problems: First, the mucus on the surface of the catfish easily adheres to the blade surface during the grinding process, causing material to stick together and reducing subsequent cutting efficiency; second, excessive mucus in the catfish meat directly affects the taste and quality of the final product, making it difficult to meet the high-quality requirements of food processing.

[0004] Therefore, an automatic meat grinder that cuts meat evenly is designed to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The mucus treatment mechanism in this invention first pre-treats the catfish meat pieces by soaking them in high-concentration salt water. During the treatment process, the rotating motion of the rotating drum and the synchronous stirring action of the stirring ring, combined with the squeezing and shearing effect of the flower-shaped extrusion roller, can effectively clean the mucus on the surface of the catfish meat pieces, thereby significantly reducing the material adhesion phenomenon of the subsequent cutting blades. At the same time, it improves the taste and quality of the processed fish meat, solving the problems of equipment blockage and unstable product quality caused by mucus residue in traditional processing methods.

[0018] 2. By cooperating the moving mechanism with the blocking plate and multiple tipping plates, this invention can effectively distribute the catfish meat pieces in the rotating drum evenly between the two sets of cutting blades below, thereby ensuring the uniform force on the cutting blades, avoiding excessive local wear, and effectively improving the service life and working stability of the cutting blades.

[0019] 3. The cutting and crushing mechanism of the present invention adopts the process of "slicing first and then crushing". The catfish meat is first sliced ​​evenly and then crushed. Compared with the traditional direct grinding method, this process can effectively avoid large pieces of fish meat (especially the parts with skin or tendons) from getting stuck at the discharge hole of the crushing barrel or the gap between the cross blades, thereby preventing equipment failure or uneven grinding.

Detailed Implementation

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 An automatic meat grinder for uniform cutting is shown, comprising a housing 1. The upper end of the housing 1 has a movable opening. A moving mechanism is provided on the front and rear sides of the upper end of the housing 1. The moving mechanism includes four fixed seats 9 and two movable seats 13. The four fixed seats 9 are respectively fixedly installed at the four corners of the upper end of the housing 1. A lead screw 10 is rotatably installed on the inner side of the two front fixed seats 9. The right end of the lead screw 10 passes through the inside of the right fixed seat 9 and is fixedly connected to the output shaft of a servo motor 11. The rear side of the servo motor 11 is fixedly installed on the right side of the housing 1 by a fastener. A sliding rod 12 is fixedly installed on the inner side of the two rear fixed seats 9. The bottom end of the front movable seat 13 is threadedly engaged with the outer surface of the lead screw 10, and the bottom end of the rear movable seat 13 is slidably engaged with the outer surface of the sliding rod 12. When the servo motor 11 is started, the servo motor 11 drives the lead screw 10 to rotate, causing the movable seat 13 to move laterally at the upper end of the housing 1.

[0031] A mucus treatment mechanism is installed at the moving end of the moving mechanism and at the moving port. The mucus treatment mechanism includes a fixed barrel 2, a rotating barrel 3, and two fixed rings 5. The inner side of the fixed barrel 2 is rotatably engaged with the outer side of the rotating barrel 3. An L-shaped drain pipe 4 and a water inlet pipe 44 are fixedly installed at the left and right ends of the inner side of the rotating barrel 3, respectively. The inner side of the left fixed ring 5 is fixedly connected to the upper right end of the outer side of the L-shaped drain pipe 4, and the inner side of the right fixed ring 5 is fixedly connected to the left end of the outer side of the water inlet pipe 44. Two sets of extrusion seats 7 and two stirring rings 6 are symmetrically installed on the outer sides of the two fixed rings 5. Each set of extrusion seats 7 consists of two units, and the inner side of each extrusion seat 7 is equipped with a rotatable and retractable flower-shaped extrusion roller 8. The flower-shaped extrusion roller 8 promotes the discharge of mucus protein from the surface of the catfish. The rotating barrel 3, the L-shaped drain pipe 4, the water inlet pipe 44, and the two stirring rings 6 work together to perform mucus stirring treatment on the catfish meat inside the rotating barrel 3. At the same time, the flower-shaped extrusion roller 8 further extrudes the catfish meat, promoting the discharge of mucus protein from its surface.

[0032] The mucus treatment mechanism also includes two first synchronous pulleys 14 and two sets of first gears 15. The inner sides of the two movable seats 13 are fixedly connected to the front and rear sides of the fixed barrel 2. Rotating shafts 16 are rotatably installed at the center of the left and right sides of the fixed barrel 2, respectively. The inner ends of the two rotating shafts 16 are fixedly connected to the center of the left and right sides of the rotating barrel 3. The front first synchronous pulley 14 is fixedly installed on the outer surface of the right end of the right rotating shaft 16. The inner side of the rear first synchronous pulley 14 is fixedly connected to the output shaft of the rotating motor 18. The outer sides of the two first synchronous pulleys 14 are synchronously connected through the first synchronous belt 17. The rear side of the rotating motor 18 is fixedly installed on the right side of the fixed barrel 2 through a fastener. When the rotating motor 18 is started, the rotating motor 18 drives the rotating shaft 16 to rotate through the two first synchronous pulleys 14 and the first synchronous belt 17. The rotating shaft 16 then drives the rotating barrel 3 and the catfish meat pieces inside it to rotate at a low speed inside the fixed barrel 2.

[0033] The left end of the L-shaped drain pipe 4 and the right end of the inlet pipe 44 pass through the interior of the left and right rotating shafts 16 respectively, and are fixedly installed on the left and right sides of the fixed bucket 2 by the mounting parts. Filter screens are fixedly installed at the bottom inner end of the L-shaped drain pipe 4 and the left inner end of the inlet pipe 44 respectively. The left end of the L-shaped drain pipe 4 is fixedly connected to the first telescopic pipe 19, and a solenoid valve 20 is fixedly installed at the connection between the L-shaped drain pipe 4 and the first telescopic pipe 19. The right end of the inlet pipe 44 is fixedly connected to the second telescopic pipe 21, and the right end of the second telescopic pipe 21 is fixedly connected to the middle of the U-shaped pipe 22. A three-way solenoid valve 23 is fixedly installed at the connection between the second telescopic pipe 21 and the U-shaped pipe 22. The outer sides of the first telescopic pipe 19 and the second telescopic pipe 21 are fixedly installed on the top of the casing 1 by the mounting parts respectively. Open one side valve of the three-way solenoid valve 23 to allow the brine in the high-concentration brine delivery pipe connected to one end of the U-shaped pipe 22 to be transported to the rotating tank 3 via the second telescopic pipe 21 and the inlet pipe 44, completely soaking the catfish meat pieces; open the solenoid valve 20 and close the valves on both sides of the three-way solenoid valve 23 to discharge the slimy sewage from the rotating tank 3 via the L-shaped drain pipe 4 and the first telescopic pipe 19; then close the solenoid valve 20 and simultaneously open the other side valve of the three-way solenoid valve 23 to allow the cold water in the cold water delivery pipe connected to the other end of the U-shaped pipe 22 to be transported to the rotating tank 3 via the second telescopic pipe 21 and the inlet pipe 44; the rotating tank 3 continues to rotate, cooperating with the stirring ring 6 to perform salt cleaning on the catfish meat pieces, and then the clean sewage is discharged through the L-shaped drain pipe 4.

[0034] The front and rear sides of the stirring ring 6 are respectively provided with inclined scraping surfaces. These inclined scraping surfaces can scrape off catfish meat pieces adhering to the wall of the rotating barrel 3 during its rotation. An extrusion shaft 24 is rotatably mounted on the inner side of each of the two extrusion seats 7. Two fixing boxes 25 are fixedly connected to the outer surface of the extrusion shaft 24 near its left and right ends, respectively. Telescopic cylinders 26 and guide rods 27 are fixedly mounted on the inner side of each fixing box 25. The telescopic end of the telescopic cylinder 26 and the movable end of the guide rod 27 are respectively fixedly connected to L-shaped plates 28 through the bottom side of the fixing box 25. The inner side of the forming plate 28 is fixedly connected to the left and right ends of the flower-shaped extrusion roller 8. A set of first gears 15 is set to two. The upper first gear 15 is fixedly installed on the outer surface of the right end of the extrusion shaft 24, and the inner side of the lower first gear 15 is fixedly connected to the output shaft of the extrusion motor 29. The outer extensions of the two first gears 15 mesh with each other. The two first gears 15 and the outer side of the extrusion motor 29 are jointly provided with a mounting box 30. The left end of the extrusion motor 29 is fixedly connected to the inner side of the mounting box 30, and the right side of the mounting box 30 is fixedly connected to the left side of a right extrusion seat 7. Two extrusion motors 29 are started, and the extrusion motors 29 drive the extrusion shaft 24 to rotate through two first gears 15. This causes the two fixed boxes 25 to drive the two flower-shaped extrusion rollers 8 to rotate at multiple angles inside the rotating barrel 3. At the same time, two telescopic cylinders 26 are started, so that the two flower-shaped extrusion rollers 8 can appropriately extrude the surface of the catfish meat below. The continuous wave-shaped design on the outer side of the flower-shaped extrusion rollers 8 makes it easier for the protrusions to cut into the fish meat, generating radial extrusion and tangential shearing forces. This mechanical action, in conjunction with the brine treatment, can effectively destroy the mucus structure on the surface of the catfish and promote the mucus to detach from the surface of the fish.

[0035] The fixed barrel 2 and the rotating barrel 3 have corresponding feeding ports on their upper sides. A feeding box 31 is fixedly installed at the feeding port on the outer side of the fixed barrel 2. A discharge port is opened on the bottom side of the fixed barrel 2, below the upper feeding port. A blocking plate 32 is rotatably installed on the inner side of the discharge port. A blocking shaft 33 is fixedly connected to the bottom end of the blocking plate 32. Multiple flipping plates 34 are fixedly installed on the bottom side of the blocking shaft 33. Connecting plates are rotatably connected to both ends of the blocking shaft 33. The upper ends of the two connecting plates are fixedly connected to the left and right ends of the bottom side of the fixed barrel 2. A blocking motor 46 is fixedly connected to the left end of the blocking shaft 33. The outer side of the blocking motor 46 is fixedly installed on the left side of the fixed barrel 2 by a mounting component. When the blocking motor 46 is started, the blocking motor 46 drives the blocking plate 32 and the multiple flipping plates 34 to rotate through the blocking shaft 33, thereby evenly flipping the catfish meat pieces in the rotating barrel 3 to the bottom.

[0036] A meat-chopping mechanism is provided inside the housing 1. This mechanism includes two cutting shafts 35, two second gears 37, and two second synchronous pulleys 39. Two sets of cutting blades 36 are respectively fitted onto the outer surfaces of the two cutting shafts 35. The left and right ends of the two cutting shafts 35 are rotatably engaged with the inner side of the housing 1. The two second gears 37 are fixedly fitted onto the outer surfaces of the left ends of the two cutting shafts 35, and their outer extensions mesh with each other. The output shaft of a drive motor 38 is fixedly connected to the left end of the rear cutting shaft 35. The outer side of the drive motor 38 is fixedly mounted on the left side of the housing 1 via a fastener. Two inclined... A crushing barrel 40 is fixedly installed on the inner bottom of the casing 1, at the outlet of the two inclined guide plates. A crushing shaft 41 is rotatably installed on the inner side of the crushing barrel 40. An auger 42 is fixedly fitted on the outer surface of the crushing shaft 41. A cross blade 43 is fixedly installed on the outer surface of the crushing shaft 41 near the left end. Multiple discharge holes are opened at the left end of the crushing barrel 40. The right end of the crushing shaft 41 passes through the right side of the crushing barrel 40 and is fixedly connected to the inner side of a second synchronous pulley 39. The inner side of another second synchronous pulley 39 is fixedly connected to the right end of a cutting shaft 35 on the rear side. The outer surfaces of the two second synchronous pulleys 39 are synchronously connected by a second synchronous belt 45. A support frame is fixedly installed at the bottom of the casing 1. The drive motor 38 drives two sets of cutting blades 36 to evenly slice the catfish meat. The sliced ​​catfish meat falls to the auger 42 below and is then transported by the auger 42 to the cross blade 43 for crushing. The crushed catfish meat is discharged through the discharge hole at the left end of the crushing barrel 40.

[0037] During use, the catfish meat chunks to be processed are first transported to the feed box 31 by the inclined conveyor belt, and then the feed box 31 guides the catfish meat chunks into the rotating drum 3. At the same time, when the catfish meat chunks fill two-thirds of the internal volume of the rotating drum 3, the transport of the catfish meat chunks is stopped. Then, one side valve of the three-way solenoid valve 23 is opened, so that the brine in the high-concentration brine delivery pipe connected to one end of the U-shaped tube 22 is transported into the rotating drum 3 through the second telescopic tube 21 and the water inlet pipe 44, so as to completely soak the catfish meat chunks.

[0038] Next, the rotating motor 18 is started. The rotating motor 18 drives the rotating shaft 16 to rotate through the two first synchronous pulleys 14 and the first synchronous belt 17. The rotating shaft 16 then drives the rotating barrel 3 and the catfish meat pieces inside it to rotate at a low speed inside the fixed barrel 2. At the same time, the fixed stirring ring 6 begins to cooperate with the stirring operation. The inclined scraping surfaces on the front and rear sides of the stirring ring 6 can scrape off the catfish meat pieces adhering to the barrel wall of the rotating barrel 3 during the rotation of the rotating barrel 3. Since the brine can destroy the cell structure of the catfish meat through osmotic pressure, causing the precipitation of sarcoplasmic proteins inside, and can also inhibit bacterial growth, it is necessary to ensure that the brine and the catfish meat pieces are fully mixed. At the same time, two extrusion motors 29 are started. The extrusion motors 29 drive the extrusion shaft 24 to rotate through two first gears 15, so that the two fixed boxes 25 drive the two flower-shaped extrusion rollers 8 to rotate at multiple angles inside the rotating barrel 3. At the same time, two telescopic cylinders 26 are started, so that the two flower-shaped extrusion rollers 8 can appropriately extrude the surface of the catfish meat below. The continuous wave-shaped design on the outer side of the flower-shaped extrusion rollers 8 makes it easier for the protrusions to cut into the fish meat, generating radial extrusion and tangential shearing force. This mechanical action, in conjunction with the brine treatment, can effectively destroy the mucus structure on the surface of the catfish and promote the mucus to detach from the surface of the fish.

[0039] Next, open the solenoid valve 20 and close the valves on both sides of the three-way solenoid valve 23. The viscous sewage is discharged from the rotating tank 3 through the L-shaped drain pipe 4 and the first telescopic pipe 19. Then, close the solenoid valve 20 and open the other valve of the three-way solenoid valve 23 at the same time. This allows the cold water in the cold water delivery pipe connected to the other end of the U-shaped pipe 22 to be transported into the rotating tank 3 through the second telescopic pipe 21 and the inlet pipe 44. The rotating tank 3 continues to rotate, working with the stirring ring 6 to perform salt cleaning on the catfish meat pieces. The clean sewage is then discharged through the L-shaped drain pipe 4.

[0040] After repeating the cleaning operation two to three times, the rotating drum 3 is rotated 90 degrees so that its upper feed port is located at the bottom discharge port of the fixed drum 2. The blocking motor 46 is started. The blocking motor 46 drives the blocking plate 32 and multiple turning plates 34 to rotate through the blocking shaft 33. At the same time, the servo motor 11 is started. The servo motor 11 drives the lead screw 10 to rotate, so that the moving seat 13 drives the fixed drum 2 and its inner mechanism to move laterally at the moving port at the upper end of the machine housing 1, thereby evenly turning the catfish meat pieces in the rotating drum 3 between the two sets of cutting blades 36 below.

[0041] Finally, the drive motor 38 is started, which drives the two sets of cutting blades 36 to slice the catfish meat evenly. The sliced ​​catfish meat falls to the auger 42 below and is then transported by the auger 42 to the cross blade 43 for crushing. The crushed catfish meat is discharged through the discharge hole at the left end of the crushing barrel 40.
