The device consists of a screw (1), a drive (2), a housing with a hopper (3) mounted on it, a wall (4) of the hopper (3), a perforated multi-zone filter (5) adjacent directly to the side wall (4) of the hopper (3) ) and surrounded by an airtight jacket (6), a partition (7), movable along the axis and dividing zones of different quality IMO, pipes (8 and 9) to divert the resulting minced meat of different quality, a valve (10) for breaking the bone, a window (11) of the valve (10) for removing the bone from the annular cavity (12), the protrusion (13) of the screw (1), which clears the bone of the annular cavity (12), the nut (14), which adjusts the clearance between the screw cone (1) and the valve cone (10) ), combined with the bearing assembly, of a stopper (15) for fixing the nut (14) from turning, a tray for removing bone residue (16), a device for collapsing the arch of raw materials (17) and guides (18) of a rounded shape located on the wall of the hopper ( 3) to advance the raw materials to the filter (5).

A disadvantage of the known device is its complexity due to the presence of a caving collar in the hopper, the implementation of a multi-zone filter with different perforations along its length, the presence of an airtight shirt and a movable partition separating zones of different meat quality over the end of the screw, and the presence of additional nozzles to divert the resulting minced meat of different quality , the presence of an annular cavity and a protrusion on the screw, cleansing the annular cavity from the bone.

The objective is to simplify the design while ensuring a sufficiently high quality meat boning.

The problem is solved in that in a device for the production of meat of mechanical deboning, comprising a housing with a loading hopper, a screw connected to a drive for rotating it, for supplying raw materials and providing pressure in the separation zone, the inner diameter of which gradually increases from the loading zone of raw materials to the processing zone ,, a perforated filter mounted on the auger with a conical end part mating through the gap with the conical part of the bone fracture valve with a window for removing bone residue, the mechanism for adjusting this gap, ACCORDING TO THE INVENTION, in the gripping part of the screw located at the bottom of the loading hopper, discharge grooves were made to ensure reliable capture of raw materials and reduce the possibility of “arch” formation; in addition to the bone destruction valve, a device for preliminary fracture of bones was inserted into the device, mounted on the screw between the hopper wall and a perforated filter and made in the form of a thick-walled cylindrical pipes with flanges at the ends, on the inner surface of which there are longitudinal semicylindrical grooves equally spaced from each other, and unloading grooves are also made in the valve for bone destruction to prevent rotation of the bone residue together with the screw and to ensure that they are pushed out of the valve window.

The inventive device has a novelty in comparison with the prototype, differing from it by such significant features as the discharge in the gripping part of the screw located at the bottom of the loading hopper, to ensure reliable capture of raw materials and reduce the possibility of the formation of "arch", the introduction in addition to the valve for destruction bones of the nozzle for preliminary fracture of bones mounted on the screw between the wall of the hopper and the perforated filter and made in the form of a thick-walled cylindrical pipe with flanges at the ends, on the inner surface of which there are longitudinal semicylindrical grooves equally spaced from each other, execution of a discharge groove in the valve for breaking the bone for prevent rotation of the bone residue with the screw and ensure that they are pushed into the valve window, which together ensure the achievement of a given result.

The inventive device can be widely used in the food industry for processing meat or bones and therefore meets the criterion of "industrial applicability".

The utility model is illustrated by drawings, which are presented on:

- FIG. 1 is a General view of the device in vertical section;

A device for the production of meat by mechanical deboning of meat (Fig. 1) comprises a housing 1 with a loading hopper 2, a screw 4 connected in series with a drive 3 for its rotation to supply raw materials and provide pressure in the separation zone, a nozzle 5 for preliminary fracture of bones mounted on screw 4 between the wall 6 of the hopper 2 and the perforated filter 7, paired with a gap with the conical end 8 of the screw 4 with its conical part 9 of the valve 10 for bone destruction and removal of bone residue, equipped with a window 11 and a tray 12 for removal of bone residue. To adjust the gap between the cone 8 of the screw 4 and the cone 9 of the valve 10, there is a nut 13 combined with the bearing assembly 14. Moreover, in the gripping part of the screw 4 located in the lower part of the feed hopper 2, discharge grooves 15 are made in the form of a recess A to ensure reliable capture of raw materials and reduce the possibility of the formation of the "arch" (Fig. 3). The screw 4 itself has an internal diameter that gradually increases from the feed zone to the processing zone (Fig. 2). The nozzle 5 is made in the form of a thick-walled cylindrical pipe with flanges 16 at the ends, on the inner surface of which there are longitudinally spaced semi-cylindrical grooves 17 (Fig. 4). In the valve 7 for bone destruction and removal of the bone residue, discharge grooves 18 are also made in the form of a groove B to prevent rotation of the bone residue together with the screw 4 and to ensure that they are pushed out into the window 11 of the valve 7. To collect the finished products, a container 19 for minced meat installed under the filter 7, and a container 20 installed under the tray 12. The device operates as follows.

The carcass or parts of the bird or fish are fed into the loading hopper 2 of the device and captured by the capturing part of the screw 4, which is rotated from the drive shaft 3. In this case, during the rotation of the screw 4, the discharge groove 13 in the form of a recess A is paired with the raw material and reliably captures it . The carcasses are fed by screw 4 into the nozzle 5, which serves to break the bones and transport the processed mass. Due to the presence in the nozzle 5 grooves 16 during the rotation of the screw 4 there is a preliminary fracture of the bones of the raw material. Further, from the nozzle 5, the raw material passes to the perforated filter 7, while the entire soft fraction (muscle tissue) is released through the perforation of the filter 7 into the container 19 installed below it. The solid fraction (bone residue) moves further to the valve 10, where, in its remote area, having maximum pressure, the bones are finally destroyed with their output into the window 11 of the valve 10 onto the tray 12, from which the bone residue enters the reservoir 20. To prevent stagnation and pressing of the bones in the valve 10, discharge grooves 18 in the form of grooves B serve. These grooves 18 prevent rotation of the bone residue together with the screw 4 due to their filling with bone residue, pushing the bones, cartilage and connective tissue into the window 11. The clearance between the cone 8 of the screw 4 and the cone 9 of the valve 10 is adjusted by a nut 13, combined with the bearing assembly 14. The bone residue falls through window 11 and is discharged along the tray 12 into the container 20.

Compared with the prototype of the claimed device has a simpler design while ensuring a sufficiently high quality of the finished product.
