BACKGROUND OF THE INVENTION The invention relates to meat tenderization devices that can be used in co-processing and catering enterprises.

A device for loosening meat portioned lumpy semi-finished products is known, which includes knife blocks with disk cutter knives, cleaning combs and a drive that provides rotation of the working parts. A disadvantage of this device is the low quality of the mechanical tenderization of pieces of meat due to the gross loosening of muscle and connective tissue. When loosening on this device, muscular tissue has a few wide incisions in one direction. This device does not allow to increase the degree of muscle tissue loosening in the event that such a need arises (for example, with tenderizing meat with increased stiffness). So with an increase in the number of working cycles of loosening (passing portions of semi-finished products through knife ripper blocks), the layering of coarse cuts and rupture of the entire structure of the piece occurs.

The closest in technical essence to the present invention is a device for tenderizing meat, which includes a bed, a needle ripper, a transporting mechanism, a limiting frame located between them, a storage tank for a softening solution, a mechanism for its supply and an actuator. However, the noted device also does not allow wide variation in the degree of muscle tissue loosening and saturation with a softening solution when it is necessary to prepare lumpy semi-finished products for frying from high-rigidity meat containing an increased amount of connective tissue (for example, from the hip and scapular carcass). The drawbacks of the device are due to its design features, which do not allow multiple loosening of pieces of meat in different directions, vary the duration of loosening over wide limits due to the stiffness of the meat, carry out the process of loosening the product in a softening solution, alternate the cycles of loosening and saturation with the solution, as well as stir and massage the product.

The aim of the invention is to improve the quality of meat tenderization.

A schematic diagram of the device is shown in FIG. 1, 2, 3.

FIG. 1 shows the proposed device, a general view, side view; in fig. 2 is a section A-A in FIG. in Fig.Z-node I in Fig.1. The device (FIGS. 1 and 2) contains electric motors 1, gearboxes 2, chain drives 3, a reciprocating mechanism 4 with a needle ripper 5, a rigidly fixed limiting frame 6 with holes for the passage of needles, mechanism 7

0 for mixing the product in the bowl, storage tank 8 and supplying the softening solution, transporting mechanism, made in the form of a rotating ring bowl 9, having a gear

5 engagement with the wheel 10 and driven them from the corresponding drive. The bowl is mounted on roller bearings 11, which move along the annular guide grooves of the stationary

0 bed 12.

The device works as follows.

Prepared for tenderization, pieces of meat are loaded into the ring bowl 9 in the free zone. For this purpose, an actuator is activated to ensure its rotation. Pre-weighed mass of mca c. the loading process is evenly distributed throughout the volume of the bowl;

0 the required amount of softening solution from the tank 8. The ratio of mass of mass and solution Determines the duration of the process of loosening and operation of the device, therefore, the necessary degree

5 loosening the muscle and connective tissue of pieces of meat. Thus, loosening is carried out until the solution is completely absorbed by the muscle tissue. To do this, include the drive of the needle ripper 5 and

0 mixing mechanism 7. A mass of pieces of meat, immersed in a softening solution, a passage through the free loading zone is fed to an annular bowl under the needle ripper 5, where the process of piercing the product with needles having the size of cutting edges 1.5-2.5 mm (Fig. 3) takes place. The bounding box 6 serves to remove the meat pieces strung on them from the ripper needles (when the ripper moves up). Annular

A solid mass of pieces of meat is fed into the free zone, where the product is saturated with solution, then into the zone of action of the mixing mechanism 7 for massaging and mixing the product in solution. After this, once again passing the free zone, the tenderizable mixture returns to the needle-ripper zone. The cycles described are continuously repeated during the rotation of the bowl until the end of the processing of the pieces of meat.

The technical and economic efficiency of the proposed device consists in using it to tenderize meat with increased rigidity (for example, for a beef shoulder and hip portion), from which lumpy semi-finished products for frying can be prepared. Nowadays, only a cutting, a thick and thin edge, and an inner and upper piece of the hip femur are used for frying, as traditional devices do not allow preparing semi-finished products for frying from a more rigid meat (for example, from a side and outer piece). hip part, shoulder of beef shank). The proposed device allows the process of tenderizing meat by its multiple needle loosening, massaging and saturation with a softening solution, which allows to prepare semi-finished products for frying from meat of increased rigidity.
