Description

The utility model relates to the grinding of meat and can be used in the food industry.

A device for grinding products is known that contains a feeding screw installed in the housing and a cutting mechanism in the form of multi-blade knives mounted on the screw and alternating grids in an elastic sleeve with the possibility of radial displacement, connected through a rigid sleeve enclosing them with a vibration exciter. [And S. No. 719587, B02C 1/06. Bull. No. 22, publ. 06/15/90].

The known design has several significant disadvantages:

- the presence of creasing and grinding of the product;

- the absence of a sliding element during cutting due to the small amplitudes of the vibrations of the gratings;

- use of an additional drive for the vibrator. An object of the invention is to increase the efficiency of grinding, reducing energy consumption during cutting.

In technical essence, the closest to the intended one is a meat chopping device, comprising a housing with a feeding screw and a cutting mechanism, made in the form of multi-blade knives mounted on the screw installed in the housing, and alternating grids, pressed by means of a tubular nozzle, while in the housing two diametrically spaced dowels are installed, the intermediate or intermediate and output gratings are made with a smaller outer diameter than the receiving one, and an oval-shaped central hole in which m is placed with the possibility of rotation along with the screw cylindrical insert, eccentrically mounted and fixed on the shank of the screw, all three lattices have two keyways [60. Patent 2187367 (Russian Federation), MKI V02C 18/30 Device for chopping meat / S.T. Antipov, S.V. Shakhov, S.S. Komissarov - Applic. 07/11/2001, No.2001119224 / 03, publ. in B.I., 2002 No. 23].

However, in the known device, the grinding process under the action of the reciprocating movement of the lattice is not effective enough, due to the small cutting angle.

The technical task is to increase the efficiency of the grinding process by increasing the angle of cutting.

The technical problem of the utility model is achieved in that in a device for grinding food raw materials containing a housing with a feeding screw and a cutting mechanism, made in the form of multi-blade knives mounted on the screw installed in the housing, and alternating grinding gratings with holes installed with the possibility of return - translational motion while two diametrically spaced dowels are installed in the housing, the intermediate and output lattices are made with a central oval-shaped hole in which a rotatable screw with cylindrical insert eccentrically planted by and fixed to the shank of the screw, new is that the output aperture pulverizer grating formed at an angle of cutting 60 ° -80 ° to the plane of its reciprocating movement.

The technical result consists in increasing the efficiency of the grinding process by increasing the cutting angle.

Figure 1 shows a device for grinding food raw materials, figure 2 - grinding grill assembly, figure 3 - grinding grill, figure 4 - diagram of the grinding mechanism.

A device for grinding food raw materials (Fig. 1) consists of a housing 1, a feeding screw 2 and a cutting mechanism, consisting of a receiving 3, an intermediate 4 and an output 5 gratings, between which multi-blade knives 6 are fixed on the shank of the feeding screw 2. two diametrically spaced dowels 7, and grooves for them are milled on the intermediate and output gratings. Also, these two lattices are made with a central oval hole, in which a cylindrical insert 8, eccentrically mounted and fixed on the auger shank, is placed rotatably with the screw (Fig. 2). The holes of the grinding grids (Fig. 3) are made at a cutting angle of 60 ° -80 ° in the direction of their reciprocating motion. Lattices and knives are tightened using a tubular nozzle 9.

The device operates as follows.

The raw material enters the housing of the device and when the feeding screw 2 is rotated, it is fed into the cutting mechanism, where due to it being pressed into the holes of the grids 3, 4, 5 and cutting the pressed pieces with knives 6, the raw material is crushed (Fig. 4). At the same time, the lattices 4 and 5, having a smaller diameter in comparison with the receiving lattice, perform reciprocating motion in the plane of the keys 7 due to the lattice inserted in the central hole of the lattice, eccentrically mounted and fixed on the rotating shank of the screw 2 of the cylindrical insert 8. As a result of the reciprocating the movement of the grids 4 and 5 there is a sliding cutting together with the knives 6, after which the chopped meat is unloaded.

Thus, the proposed device for grinding products has the following advantages:

- the inclined location of the holes increases the grinding efficiency;

- reduced energy costs for grinding;

- reduced creasing and grinding of crushed raw materials.
