Description

The invention relates to meat processing devices, in particular to hand tools for loosening meat.

A device is known that contains an impact mechanism and a drive that provides reciprocating motion of the hammers. [CN 215958070 U, A22C 7/00 (2006.01), A22C 9/00 (2006.01). 08.03.2022]

The disadvantage lies in the contamination of pieces of processed meat with metal particles and lubricants, which inevitably appear during the operation of the mechanical drive and friction units of the percussion mechanism. In addition, splashes of meat juice that occur during impacts also contaminate the device, which leads to the need for laborious sanitization of the device.

A device for processing meat products is known, which contains a base and a power unit. A mounting plate is attached to the base, on which a removable hammer head is located, combined with a turntable. [CN 114009476, A22C 17/00 (2006.01), A22C 9/00 (2006.01). 08/02/2022]

The disadvantage lies in the high labor intensity of sanitizing the device due to contamination from splashes of meat juice, and from direct contact of the hammer head and turntable with meat.

Known tenderizer for loosening meat, containing a base, a housing, a hammer, a rotary clamping mechanism, a rotary adjusting mechanism and a transmission mechanism. [CN 216821513 U, A22C 9/00 (2006.01), 06/28/2022.]

Known meat tenderizer containing a hammer and an electromechanical drive. The tenderizer does not destroy the cells inside the meat, and the loss of meat juice is minimized. [DE 2504706 A1, A22C 9/007, A47J 43/28, 08/19/1976]

A common disadvantage of the mentioned devices lies in the high labor intensity of sanitizing the device due to contamination from splashes of meat juice, and from direct contact of the hammer head with the meat.

The closest technical solution is a device for mechanical processing of meat, consisting of an electromechanical drive, a rod and a hammer, mounted by means of a housing. [DE 4428509 A1, A22C 9/00, A22C 7/00, 15.02.1996]. The disadvantage lies in the contamination of pieces of processed meat with metal particles and lubricants, which inevitably appear during the operation of the mechanical drive and friction units of the percussion mechanism. In addition, splashes of meat juice that occur during impacts also contaminate the device, which leads to the need for laborious sanitization of the device.

The purpose of the invention is to reduce the complexity of sanitizing parts of the device after its intended use.

A new technical result that can be obtained by implementing the invention consists in the complete exclusion of direct contact of the processed meat with the details of the device, the exclusion of the ingress of metal particles and lubricant on the meat, which inevitably appear during the operation of the friction units of the device mechanism.

The proposed technical result is achieved by the fact that the tenderizer consists of a reciprocating electromechanical drive, a hammer, the working part of which is equipped with spikes, and a rod is attached to the non-working part. At the end of the rod opposite from the hammer, there is a shank, the shape of which is intended for connection with an electromechanical reciprocating drive. A stop is made between the hammer and the shank on the surface of the rod, under which a spring is installed in the direction of the hammer, pressed against the sleeve with an axial hole in which the rod is located. The outer surface of the bushing is provided with at least three supports, and the axial hole of the bushing is provided with cuffs along the edges. At the ends of the supports, elastic clamps are made, in which a disposable membrane and a ring are rigidly fixed, the surface of which is completely covered with a disposable membrane. Thus, the totality of the distinguishing features of the invention, presented in the formula, provides a causal relationship between the technical result and the mentioned features.

The claimed device differs from the prototype in that the axial hole of the sleeve is provided with cuffs along the edges, and elastic clamps are made at the ends of the supports, in which a disposable membrane and a ring are rigidly fixed, the surface of which is completely covered with a disposable membrane.

The general view of the device is shown in Fig. 1. The device consists of an electromechanical reciprocating drive (not shown), which can be used as a puncher, hammer 1, the working part of which is equipped with spikes. A rod 2 is attached to the non-working part of the hammer 1, on the opposite end of which the shank 3 is located, the shape of which, for example, of a hexagonal section, is intended for connection with an electromechanical reciprocating drive. A stop 4 is made between the hammer 1 and the shank 3 on the surface of the rod 2. Under the stop 4 in the direction of the hammer 1, a spring 5 is installed, pressed against the sleeve 6 with an axial hole in which the rod 2 is located. The axial hole of the sleeve 6 is provided with cuffs 7 along the edges. the surface of the sleeve 6 is provided with at least three supports 8, at the ends of which elastic clamps 9 are made. In the elastic clamps 9, a disposable membrane 10 and a ring 11 are rigidly fixed, and the surface of the ring 11 is completely covered with a disposable membrane 10. The details of the device are made of stainless steel, cuffs 7 is made of PTFE, and the disposable membrane 10 is made of a flexible material such as polyethylene.

The device works as follows. A disposable membrane 10 is placed on the working surface of the table, on which a ring 11 is placed. The edges of the disposable membrane 10 are wrapped around the ring 11, elastic clamps 9 are pressed against the ring 11, thereby ensuring the rigid fastening of the disposable membrane 10 and the ring 11. The shank 3 is fixed in an electromechanical drive reciprocating action, move the device so as to cover the processed piece of meat with a disposable membrane 10, and achieve tight contact of the ring 11 with the table surface. Then the electromechanical drive is turned on, thereby driving the rod 2 inside the sleeve 6. By pressing the reciprocating electromechanical drive, the spring 5 is compressed. disposable membrane 10. With repeated reciprocating movement of the rod 2 inside the sleeve 6, the formed particles of metal and lubricant do not go beyond the limits limited by the cuffs 7. After processing a piece of meat, they proceed to the next one. After the end of work, the ring 11 is pressed against the table surface, the sleeve 6 is moved upwards and the elastic clamps 9 are detached from the disposable membrane 10 and the ring 11. The ring 11 is removed from the surface of the disposable membrane 10. The contaminated disposable membrane 10 is disposed of. For uncontaminated surfaces of the device, minimal sanitization is carried out.

The technical effect of using the device is to reduce the laboriousness of sanitizing the parts of the device after its intended use due to the complete exclusion of direct contact of the processed meat with the details of the device and the exclusion of metal particles and lubricant from getting on the meat and the outer surfaces of the device.
