Abstract

The grille for the food grinder is made in the form of a disk with a central cylindrical hole and through end holes. Through end holes are made in the form of part of a sphere with cutting edges with a sharp cutting angle).

Description

The useful model belongs to devices for grinding food products, mainly meat, and can be used in the food industry, catering enterprises and household.

A grate for a device for grinding food products is known, which has the shape of a disk with a central cylindrical hole for its attachment to the shaft, through holes for cutting and passing meat, which are made in the form of rings, and recesses located between the through holes and with connect the through holes of each ring along an arc in the direction of rotation of the knife, the recesses are in the form of a trough with a radius of the forming surface equal to the radius of the holes, and a recess from the center to the periphery from the hole of one ring to the hole of the next ring at an angle greater than the angle of friction of the meat the surface of the grid, while the surface of the holes facing the periphery is made at an angle in the direction of rotation of the knife (Patent of Ukraine Mo 60136, IPC: А22С 17/00, В02С 18/30. Grid for a device for grinding food products / Hvozdev F.Yu ., Shpyganovych T.O., Krasnikova S.V. - Mo 201014213:, application 06/29/2011; published 06/10/2011 Mo 111 Blvd.

The disadvantage of the device is: high consumption of energy to overcome frictional forces between rotating knives and grids; a high degree of compression of minced meat and excessive release of meat juice due to excessive pressure on the side surfaces of the through holes for cutting and passage of meat.

The closest analogue is the grate to the device for grinding food products, which has the shape of a disk with a central cylindrical hole and through end holes.

The recesses are made on one or both ends and are located between through holes

The grid works as follows. The material to be crushed is fed by an auger to the cutting mechanism, which consists of one or more grates and the corresponding number of knives. Due to the rotation of the auger, the material to be crushed is pushed into the through end holes and cut by the rotating knife.

The disadvantage of such a cutting mechanism is: excessive release of moisture (meat juice during meat processing) and increased energy consumption due to the insufficient sharpness of the cutting edge of the grate.

З The useful model is based on the task of improving the grate for the device for grinding food products by making through end holes of the grate. in the form of a part of a sphere with cutting edges with a cutting angle a, which increases the sharpness of the cutting edges of the grid, which improves the quality of cutting the product.

The task is solved by the fact that in the grate for the device for grinding food products, which is made in the form of a disk with a central cylindrical hole and through end holes, according to a useful model, the through end holes are made in the form of a part of a sphere with cutting edges with a cutting angle a.

The execution of end through holes in the form of a part of the sphere provides increased sharpness of the cutting edges of the grid with a sharper cutting angle, which leads to a decrease in energy consumption for the cutting process and an increase in the quality of the product, due to a decrease in the release of juice from the product (for example, meat juice when grinding minced meat) due to less pressure on the processed product. Spherical holes are quite easy to make on modern metalworking machines, and in case of wear and blunting of the working edges, they are easy to restore with a slight increase in the diameter of the hole.

The essence of the useful model is explained by the drawings, where in fig. 1 shows a general view of the grate for the device for grinding food products, and in fig. 2 fragment of the grid with a spherical opening.

The grate 1 to the device for grinding food products (Fig. 1) contains a central cylindrical hole 2 for fixing the grate and through end holes C (Fig. 2) for grinding and the passage of the product, which have the shape of a part of a sphere with cutting edges 4 with a cutting angle a , which is formed as a result of making lattice holes in the form of part of a sphere.

The mechanism works as follows.

The food product to be ground is fed by the auger of the device (not shown) to the cutting mechanism (not shown), which consists of one or more grids 1 and the corresponding number of knives. Thanks to the rotation of the auger, the crushed product is pushed into the through end holes of the grid 3, and is cut by a rotating knife.

Thanks to the execution of through end holes for grinding and the passage of the product C in the form of a part of the sphere, cutting edges 4 with sharp cutting angles a are formed. Reducing the cutting angles c in this technical solution leads to a decrease in specific energy consumption for the cutting process and a decrease in the degree of compression of the product, which improves its quality.
