Description

 The invention relates to the meat industry, and can be used in meat processing plants for grinding and separating pulp from tendons and connective tissues.

 A device for trimming meat is known, containing a perforated drum, inside which a screw is rotatably located (see the USSR AS N 1692489 class A 22 C 17/00, 1991).

 A disadvantage of the known device is that it cannot be used for lodging various types of meat, which reduces the technological capabilities of the equipment and adversely affects the products. In addition, the device has a complex structure, expensive to manufacture and inconvenient to operate.

 Achieved with the use of the proposed device, the technical result consists in expanding the technological capabilities of the equipment and improving the quality of the products.

 To do this, in the device for meat stripping, containing a perforated drum with a screw located inside for rotation, the drum is made of two interconnected parts, a cylindrical one equipped with a faceplate and a conical one turning into a pipe with an adjusting nut mounted on it, and the shaft made hollow with a variable diameter and equipped with a landing socket for connecting to the auger of the top.

 The drawing shows a schematic General view of the device.

 The meat trimming device comprises a perforated drum 1 with holes 2, a faceplate 3, an outlet pipe 4, in which an adjusting nut 5 is installed, a screw 6 with a hollow shaft 7 of variable diameter, which is equipped with a seat socket 8 and a turn 9.

 A device for trimming meat works as follows. At the outlet of the top of the top, the union nut 10 (clamping nut) is unscrewed. Install the device in the neck so that the seat socket 8 (see Fig. 1) of the screw 6 engages with the output end of the shaft of the spinning auger, while the faceplate 3 of the drum 1 with its slot should engage with the key installed in the neck housing. Screw the union nut 10 into the top of the top of the top until the faceplate 3 is pressed firmly, pre-screwed onto the perforated drum 1. The device is ready for operation. Feed the meat into the spinning top and turn on the drive. The crushed raw material at the outlet of the neck of the top is picked up by a screw 6 and moves along the drum 1 to the perforation zone. In the perforation zone with holes 2, the height of the turn 9 of the screw b starts to decrease due to the diametrical increase in the hollow shaft 7, increasing the force of compression of the meat raw material. The pulp tissue in its strength properties is much weaker than the connective, therefore, the first one begins to flow through the holes 2 of the perforation, and the connective tissue continues to move with the screw b in the axial direction. There is a separation of raw meat into two streams. The pulp tissue is squeezed out in the radial direction and through the holes 2 it enters the storage tank, and the connective tissue, moving in the axial direction, enters the outlet pipe 4 and through the hollow adjusting nut 5 into the collector. By screwing or unscrewing the adjusting nut 5, the passage section of the outlet pipe 4 is reduced or increased, thereby increasing or decreasing the compression force by the screw 6 of the meat raw material in the perforation zone. Thanks to this technical solution, in the process of operation of the top, it is practically possible to select any housing regime for all types of raw meat, including low ones with a content of meat tissue of less than 50%. This allows you to significantly expand the technological capabilities of equipment and improve product quality.

 It is known that the highest grade of meat does not have visible inclusions of connective tissue, in the first grade the presence of connective tissue is allowed up to 6%, in the second grade - up to 20%, etc.

 If it is necessary to increase the grade of meat raw materials, for example, to obtain the highest quality from the first or second grade, it is advisable to remove the entire package of cutting tools from the top of the top or leave only the intake grill with a knife, since it makes no sense to grind meat with a low content of connective tissue, so as not to subject the meat to additional heat.

 At the end of the device, unscrew the union nut 10 on the outlet neck of the top, take out the drum 1 with the screw 6. On the drum 1, unscrew the faceplate 3, take out the screw 6 and carry out sanitization.

 Thus, the proposed device for meat trimming significantly expands the technological capabilities of the equipment by regulating the compression force of meat raw materials in the perforation zone, thereby increasing the quality or grade of meat raw materials. The device is compact and convenient to use, as It is a nozzle on the outlet neck of the top and does not require an additional drive.
