Technical Field

[0001] The utility model belongs to the field of food processing machinery, in particular to a tendon separation device for a meat grinder. Background Art

[0002] A meat grinder is one of the most commonly used devices in the meat processing process. Most sausage productions have to go through the process of grinding meat. Some meat products such as hamburger patties, frankfurters, fermented sausages, etc. must remove tendons during the processing. This is because tendons will increase the hardness of the meat, affect the taste of the meat products, reduce the edible value of the meat, and the existence of tendons greatly affects the quality of the meat products.

[0003] Generally, the meat obtained directly by a meat grinder contains tendons. Usually, manual screening is adopted and then put into a special tendon separation machine for separation. Using this operation method increases the labor intensity of workers, increases the working time, and is not conducive to improving work efficiency.

[0033] As Figure 1 shown, the present utility model provides a tendon separation device for a meat grinder, including: an auger connecting shaft 3, a tendon conduit 10, and a tendon discharge pipe 14.

[0034] As Figure 1 shown, the auger connecting shaft 3 is installed on the auger box 1, and a pre - cutting orifice plate group 4, a first reamer 5, a first orifice plate 6, a tendon separation reamer group 7, and a separation orifice plate 8 are sequentially installed on the auger connecting shaft 3 from the inside out.

[0035] As Figure 2As shown in the figure, it is a schematic structural diagram of the pre-cut orifice plate group of the present utility model. The raw meat is extruded by the spiral structure on the auger shaft 2 to the pre-cut orifice plate group 4, and the raw meat is extruded and compacted. As Figure 3 shown in the figure, it is a schematic structural diagram of the first reamer of the present utility model. The spiral structure on the auger shaft 2 generates pressure on the meat material, causing the raw meat to flow out from the pre-cut orifice plate group 4 and be minced by the first reamer 5. Specifically, the first reamer 5 is cross-shaped, including a central part 51 and a blade part 52, and the central part 51 is annular. As Figure 4 shown in the figure, it is a schematic structural diagram of the first orifice plate of the present utility model. The first orifice plate 6 is annular and is provided with a plurality of holes 61. The rotating first reamer 5 performs a shearing action with the holes 61 on the first orifice plate 6 to cut the meat material into smaller-sized meat material with tendons, and the meat material with tendons is squeezed into the first orifice plate 6.

[0036] As Figures 5 - 8 shown in the figure, the tendon separation reamer group 7 includes a second reamer 71 and blades 72. The second reamer 71 has a blade main body 711 and a reamer mounting shaft 712. The angle between each adjacent blade of the blade main body 711 of the second reamer 71 is 90 degrees. The inner side blades of the blade main body 711 of the second reamer 71 have second reamer edges 713. The outer side blades of the blade main body 711 of the second reamer 71 are provided with blade mounting grooves 72. The blades 72 are vertically mounted on the blade mounting grooves 72 and protrude from the blade mounting grooves 72. The reamer mounting shaft 712 is mounted at the center of the outer side of the blade main body 711 and is mounted with the auger connecting shaft 3. There is a tendon through groove 714 on the side away from the auger connecting shaft 3.

[0037] As Figure 9 shown in the figure, the separation orifice plate 8 has meat material discharge holes 81 and tendon guiding grooves 82. The meat material discharge holes 81 are distributed on the separation orifice plate 8. The tendon guiding grooves 82 are long grooves extending from the edge of the separation orifice plate 8 towards the middle and are communicated with the tendon through grooves 714 on the reamer mounting shaft 712 of the tendon separation reamer group 7. When the second reamer 71 rotates, the blades 72 on the outer side of the blade main body 711 of the second reamer 71 mince the meat and squeeze the minced meat into the meat material discharge holes 81 on the separation orifice plate 8. The tendons are squeezed into the tendon through grooves 714 of the second reamer 71 through the tendon guiding grooves 82 on the separation orifice plate 8. The meat material with tendons extruded from the first orifice plate 6 is processed by the second reamer 71, and the meat material is scraped into the meat material discharge holes 81 on the separation orifice plate 8 by the blades 72 on the second reamer 71. The tendons are squeezed into the tendon through grooves 714 by the tendon guiding grooves 82, realizing the separation of the two. When the second reamer 71 performs tendon separation, only the blades 72 protruding from the second reamer 71 will be worn. After wear, only the blades 72 need to be replaced, which will not cause overall wear of the reamer, improve the utilization rate of the reamer, reduce the scrapping of the reamer, and is beneficial to saving resources.

[0038] As Figures 1 - 9 shown, the tendon conduit 10 is installed on the auger shaft 2 and connected to the tendon through groove 714 of the tendon separating reamer set 7; the tendon discharge pipe 14 is connected to the tendon conduit 10. When the machine is working, the tendon flows from the tendon conduit 10 to the tendon discharge pipe 14 along the tendon through groove 714 between the separating orifice plate 8 and the second reamer 71, while the meat material is discharged through the meat discharge holes 81 on the separating orifice plate 8, and the two can be separately collected. In addition, the fixed pipe 11 is installed on the tendon conduit 10, a tendon separating seat 9 is installed at one end of the fixed pipe 11, and a coupling sleeve 12 is installed at the other end of the fixed pipe 11; the positioning sleeve 13 is installed between the tendon conduit 10 and the tendon discharge pipe 14.

[0039] The usage method of this device is as follows:

[0040] 1. The spiral structure on the auger shaft 2 squeezes the raw meat to the pre-cut orifice plate group 4, and compresses the raw meat. The spiral structure on the auger shaft 2 generates pressure on the meat material, causing the raw meat to flow out from the pre-cut orifice plate group 4 and be minced by the first reamer 5.

[0041] 2. When the first reamer 5 rotates, it generates a shearing action with the holes 61 on the first orifice plate 6 to cut the meat material into smaller sized meat material with tendons, and squeezes the meat material with tendons into the first orifice plate 6.

[0042] 3. The meat material flowing out from the first orifice plate 6 is continuously minced by the second reamer 71 of the tendon separating reamer set 7. When the second reamer 71 rotates, the blades 72 on the outer side of the blade body 711 of the second reamer 71 mince the meat and squeeze the minced meat material into the meat discharge holes 81 on the separating orifice plate 8, and the tendons are squeezed into the tendon through groove 714 of the second reamer 71 through the tendon guiding grooves 82 on the separating orifice plate 8.

[0043] 4. Then, the tendon flows from the tendon conduit 10 to the tendon discharge pipe 14 along the tendon through groove 714 between the separating orifice plate 8 and the second reamer 71, while the meat material is discharged through the meat discharge holes 81 on the separating orifice plate 8, realizing the separate collection of the two.

[0044] The spiral structure on the auger shaft 2 of the present device sequentially pushes the raw meat to the pre-cut orifice plate group 4, the first reamer 5, the first orifice plate 6, the tendon separation reamer group 7, and the separation orifice plate 8. The raw meat is minced layer by layer by multiple reamers, and the size of the raw meat gradually becomes smaller to obtain the meat material of the required size, improving the taste of the meat quality and meeting the production expectations. The tendons are discharged into the tendon discharge pipe 14 through the tendon through groove 714 between the separation orifice plate 8 and the second reamer 71, and the meat material is discharged from the meat material discharge hole 81 of the separation orifice plate 8. While mincing the meat, the tendons and the meat material are effectively separated, saving working time and improving work efficiency and quality. In addition, when the second reamer 71 of the tendon separation reamer group 7 of the present device separates the tendons, only the blades 72 protruding on the second reamer 71 will be worn. After wear, only the blades 72 need to be replaced, which will not cause overall wear of the reamer, improving the utilization rate of the reamer, reducing the scrapping of the reamer, and being beneficial to saving resources.
