Description

The invention relates to a grinding technique, in particular to the preparation of fine ground meat for the production of structureless cooked sausages and sausages.

The purpose of the invention is to reduce energy consumption while improving the quality of the finished product.

FIG. 1 shows the device section; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 - the same, option; in fig. 5 is a diagram of the operation of the pneumatic vibrating drive of the knives.

The device includes a base 1, on which is placed a vacuum chamber 2c with a lid 3. In the chamber 2, coaxially with it, is placed a container 4, rotating with the help of actuator 5. Inside the container 4 coaxially with it is placed the head 6 fixed on the lid 3. Inside the head 6, coaxially with it, is placed a channel 7 for feeding meat into the lower part of the tank 4, communicating with a feed pump (not shown) by means of a stuffing line 8. On the head 6, disk knives 9 are placed with the possibility of radial reciprocating movement, Each circular knife 9 has six workers each position and is mounted on the holder 10, which allows adjustment of the gap between the cutting edges of the knives 9 and the inner surface of the container 4.

The holders 10 are rigidly connected with the rods 11, fitted with springs 12, which hold the knives 9 in the position of the most distant cutting edge from the wall of the container 4.

The rods 11 are connected to a modular pneumatic vibration actuator, each module of which is autonomously connected to an air distributor, mainly of a spool type (not shown).

The module includes two pairs of cylinders 13, 14 and 15, 16 with impactors 17–20, respectively. The compressed air is supplied through channels 21 and 22, drainage through channels 23-26.

The drums divided the cavities of the cylinders into chambers: 27 — the idling chamber of the first cylinder, 28 — the working stroke chamber of the first cylinder, 29 and 30 — the idling chamber of the second cylinder, 31 — the idling chamber of the third cylinder, 32 — the third stroke working chamber. cylinder, 33 - idling chamber of the fourth cylinder, 34 - working stroke chamber of the fourth cylinder. The camera 27 idling the first cylinder 13 is connected by a channel 35 with the camera 34 of the stroke of the fourth cylinder 16, the camera 29 of the idling of the second cylinder 14 is connected by channel 36 with the camera 32 of the stroke of the third cylinder 15, the camera 31 of the third cylinder of the third cylinder camera 30 of the stroke of the second cylinder 14, and the camera 33 of the idling of the fourth cylinder 16 is connected by a channel 38 with the camera 28 of the stroke of the first cylinder 13.

The modules are located on the outer surface of the blade head in a spiral, the rise of which coincides with the direction of rotation of the container 4.

To unload the finished product at the end of the grinding process, a scraper 39 is provided, removing the stuffing from the vessel wall 4, and a screw conveyor 40 with a drive 41 and a pipe 42.

For servicing the mincer (washing, adjusting the installation of circular knives, removing knives for regrinding, etc.), hydraulic cylinders 43 are provided, thanks to which the cover together with the knife head 6 and the discharge device 40 moves upward, opening access to both the knife head 6 and and to the inner surface of the container 4.

The method is implemented as follows.

Initially, using the drive 5, the capacity 4 is unwound to a working speed of 520 rpm, then the feed pump is simultaneously turned on with the air-distributing device of the knife vibration drive (not shown) and the screw conveyor 40. The feed product 8 is fed along the axial channel 7 to the bottom of the tank 4.

In the container 4, the product is distributed evenly along its inner wall using centrifugal forces. The entry of new portions of the original product into the bowl puts pressure on the previous layers and the stuffing moves up along the wall of the container 4 and compresses. The entry of new portions of the original product into the bowl exerts pressure on the previous layers and the stuffing moves upwards along the wall of the tank 4, where it is crushed. The finished product is continuously removed from the wall of the container 4 by the scraper 39 and with the aid of a screw conveyor 40 equipped with an actuator 41, is brought out through the pipe 42 to the outside. During operation, a vacuum is maintained in the vacuum chamber 2.

The operation of the pneumatic vibratory drive of the blades is illustrated by the example of one module. Compressed air is supplied by an air-distributing device (not shown) through channel 21 to chamber 27 of idling of the first cylinder 13, and part of air through channel 35 to chamber 34 of a stroke of fourth cylinder 16. Simultaneously compressed air

supplied through channel 22 to the idle chamber of the second cylinder 14, and part of the air through channel 36 to the camera 32 of the third cylinder 15 stroke.

The idle stroke of the strikers 17 and 18, which move towards each other, begins. As soon as the strikers 17 and 18, when they move, open the exhaust holes 23 and 24, the pressure in the chambers 27 and 29 drops and when the strikers 17 and 18 reach their extreme positions and the strikers 19 and 20 strike the disks 11 of the discs, the compressed air begins enter through channel 38 into chamber 33 of idling of fourth cylinder 16, and through channel 37 - into chamber 31 of idling of third cylinder 15.

The idle stroke of the strikers 19 and 20 and the working stroke of the strikers 17 and 18 begin. In the following, the described process is repeated.

During the working stroke of the rods, the product is cut and at the same time the springs 12 are compressed, which return the disks to their original position. The same springs keep the cutting bodies of the reserve (unused) modules in the position of the greatest distance from the cutting edge of the knife 9 from the inner surface of the container 4, i.e. not shipped in stuffing.

Due to the oncoming movement of the impactors, vibrations from shocks to the rods are localized inside the housing. The presence of a vacuumized space around the container almost completely isolates the space around the device itself for the grinder of a product from noise. When blunting knives without stopping the machine, turn off modules with blunt knives and turn on backup modules. It is most efficient to introduce backup modules in the lower sections of the head, where dulling occurs faster than in the upper ones.

When exposed to a vacuum product, its viscosity increases 1.5 times, respectively, the de-aeration intensity decreases. The radial reciprocating movement of the knives destroys air bubbles and facilitates their exit from the meat mass, thus facilitating the deaeration of the product and improving its quality due to better preservation.

The device allows to vary widely depending on the initial state of the product and the technological requirements for the finished product, the feed rate of the product for grinding, the frequency of vibrations and the number of vibro-knife.
