The guides 3, 4 are installed symmetrically opposite convex sides and in the middle part of the parallel window (or slots) 5 disk serrated knives 6. The blades 6 attached in series with a uniform pitch in the regulated and unregulated knife blocks 7, 8 parallel hexagonal shafts 9, 10 respectively. The block 7 is adjustable in the sense of availability of the regulation, its provisions and banana efforts. The shafts 9, 10 kinematically connected double row chain transmission with a drive motor 11 with the possibility of counter-rotation and installed along the concave sides mentioned the guides 3, 4 with the formation of the longitudinal gap between the cutter blocks 7, 8. The blades 6 of the last act in the gap between the rails 3, 4 through the window 5. Adjustable unit 7 is equipped with a spring-loaded lever-rocker regulating mechanism for regulating a gap between the cutter blocks 7, 8 and effort interacting with the processed product, with adjustable blade unit 7 is made with a number of circular knives 6, 55, i.e. one less number of disk knives 6 unregulated knife block 8, equal to 56. The teeth 12 of the circular knives 6 are trapezoidal, radially directed and placed on a circle with the business step 13° ±0,5°. Knives 6 of each of the blocks 7 and 8 are shifted by half of the interval between adjacent blades 6, i.e. knives 6 blocks 7, 8 are rotated in different planes. The shaft 9 of the adjustable knife block 7 kinematically connected to the driving sprocket 13 of the chain transmission having a number of teeth equal to seventeen, i.e. less by two than the sprocket 14 with nineteen teeth and kinematically connected with the shaft 10 unregulated knife block 8. Basket 2 is made with two grooves 15 in the end walls and with the tabs 16 to adjust the mutual positions of the guides 3, 4. The teeth 12 are arranged with a specified angular step, therefore, the rotary blade 6 on the hexagonal shaft (with faces that are at an angle of 60°) installed with the formation of their teeth 12 (and the depressions between them) spiral lines, and a spiral line on the unregulated unit 8 knives right, and on the regulated unit 7 to the left. Between the blades 6 on the shafts 9,10 have the same metal rings (not labeled).

The drive motor 11 is made as a gear motor with a sprocket wheel 17 on the shaft. Chain transfer is performed row, these sprockets 13, 14, 17 and idler sprocket 18 mounted on spring-loaded swivel axis 19, is made double.

Lever-rocker mechanism is spring-loaded by a set of Belleville springs 20, which are positioned around the threads of the first shaft 21 with the stop 22 on the lower end. On the threaded part of the rod 21 mounted an adjusting nut 23 and nut 24 scenes lever-rocker mechanism. Lever-rocker mechanism is dual, i.e., the levers connected to the intermediate shaft 25, pair. The shafts 9, 10 are on the edges of the pair of hex nuts 26 with left-hand thread and the nut 27 with right-hand thread, tightening the blades 6. Nuts 26, 27 are placed in the hex return holes stepped shafts 28-31, installed in a dual bearing supports (not labeled). The shafts 28, 30 are installed with the possibility of axial displacement. The bolts 32, 33 are designed to regulate the location of the knives 6 unit 7 relative to the knives 6 block 8 along the axes of the shafts 9, 10.

Case tenderizer made with doors and is equipped with a locking device, which is controlled by a sensor in the form of a reed switch, to disable the rotating parts with open doors (not illustrated).

The knives 6, the housing, the hopper 1, the guides 3, 4 are made of stainless steel.

A bearing support shafts 28, 30 are closed by caps 34, 35.

Tenderizer works as follows.

In the hopper 1 put the product to be processed, which is usually a piece of meat. Then the product is promoted, while he will not fall between the rails 3, 4. The product falling under its own weight, into the space between the rotating is Misia knives 6 blocks 7, 8. Here is the contact with the teeth 12 of the knives 6, i.e. reciprocating tenderization. Tenderization is carried out by the knives 6 along a helical line and serves to provide a natural relationship between muscle tissues.

In the process, two knife block 7, 8 at opposite rotation is incised to a depth of, preferably, 0.5 to 1 cm product coming from the hopper 1. Due to the different number of teeth of the sprockets 13, 14 and rotation of blocks 7, 8 takes place at different speeds, i.e. alternately knives set of 6 with different sides of the product have different speed and slip relative to each other in the processed products, the effectiveness of tenderization thereby increases. Different direction of the thread of the screws 26, 27 prevents them from screwing with the opposite rotation. The distance between the cutter blocks 7, 8 and the guides 3, 4 set nut 24 when the rotation shaft 21, depending on the size of the product, while maintaining the set pressure and the depth of treatment. To change the position of the adjustable knife block 7 is a rotation of the stem 21, clockwise to increase the distance, anticlockwise for convergence of blocks 7, 8. Changing the gap between the rails 3, 4 is carried out by moving along the slots 15 with fixing clamps 16. The presence of the guides 3, 4 excludes nakruchival the e product of knife blocks 7, 8.

By screwing-unscrewing of the bolts 32, 33 to adjust the mutual position of the knives 6 blocks 7, 8, so that each knife 6 one block was rotated in the plane passing through the middle of the gap between adjacent blades 6 of another block. Change efforts set of springs 20 is made by rotation of the nut 23 on the shaft 21 in a clockwise direction to compress the spring 20, counterclockwise to loosen. Double row chain transmission provides the reduction of the size of tenderization and torque on the shafts 28 to 31.

The force of the set spring 20 determines the resistance to the passage of solids - by accident, bones etc. the block 7 has the ability, compressing the spring 20 through the lever-rocker mechanism to temporarily shift and skip the solid object, and then return to its working position. Thus, the increased probability of tenderizer, i.e. its reliability.

Flushing of the working bodies of tenderization is performed after each shift to prevent the multiplication of microorganisms. For washing the blocks 7, 8 knives 6 and the guides 3, 4 are disassembled from the housing. When removing the blocks 7, 8 removable cover 34, 35, shift (figure 3 left) bearings with shafts 28, 30. Thereby exempt nuts 26, 27 and blocks 7, 8 can be removed for washing. Rational design is tion tenderizer part of the dismantling of the blocks 7, 8 makes it easy to comply with sanitary standards for food processing equipment.

If necessary (for unilateral nadareski products with skin) blade unit 8 may not have blades with 6 teeth 12, i.e. replaced by a cylindrical shaft (not illustrated).

Good binder properties are provided with maximum contact surface of the product obtained by notching his knife 6, due to the release of intracellular proteins. When this meat is loosened fabric that promotes better retention of fluid inside the meat and makes the end product more tender. For example, tenderization carbonate increases the fixation of brine and the product yield of 1-2%.

Tenderization reduces shrinkage during cooking and increases the yield, promotes uniform distribution of brine and spices volume of product.

Options tenderizer developed in accordance with the present invention, the following.
