(54) DEVICE OF THE DPJ CRUSHING OF FOOD PRODUCTS

(57) The invention relates to a device for grinding food products and makes it possible to increase the efficiency of the grinding process. The device includes a housing 1 with a receiving hopper 2, a screw feeder 3 with a hollow shaft 4, inside of which is located the shaft 5 of the cutting mechanism, and a reversible drive consisting of a receiving 7 and output grids between which the knife 6 is located. The knife 6 is designed as uniform located along the perimeter of the hub of a pair of blades 10 with cutting edges on the side surfaces, the angle between the blades being 90, and at the junction of them are mounted bosses for hinging on the hub. 2 Il.

The invention relates to devices for grinding products and can be applied in food and other industrial areas.

The purpose of the invention is to increase the efficiency of the grinding process.

Fig. 1 shows a device for grinding food products, a general view; 2 shows the construction of a knife.

The food grinding device comprises a housing 1, with a receiving hopper 2, a screw feeder 3 with a hollow shaft 4, inside which the shaft 5 of the cutting mechanism consisting of a knife 6 located between the receiving 7 and output B lattices is coaxially located. The knife 6 is made in the form of 9 blades 10 evenly spaced along the perimeter of the hub with cutting edges 11 and 12 on the side surfaces. The angle between the blades is equal to 90 °, and at the junction the bobiki 13 are mounted for swiveling on the hub 9 by means of axles 14. The drive consists of an electric motor 15, a coupling 16, a two-way gearbox including gears 17-22, a second shaft 23, shafts 24 and 25 and half couplings 26 and 27.

The device works as follows.

In preparing the device for operation on the shaft 5 of the cutting mechanism, a knife 6, a reception 7 and an output grid 8 are installed. The raw materials are supplied to the auger feeder 3 through the receiving bin 2. The electric motor 15 is turned on, transmitting torque through the clutch 16 to the two-speed gearbox, providing rotation of both the screw feeder 3 through gears 17 to 19 and through the hollow shaft 23, and the knife 6 through shafts 5 and 24, which are interconnected by a splined connection, due to the interaction of the cams on the hub of gear 20 and on the half coupling 26, which is connected by a splined connection to the hollow shaft 23, and in the case of reversible rotation of the knife 6, soap has coupling half 27 and the loose on the shaft 25 through a gear 21

gear 22 to gear 20. Changing the direction of rotation of the knife 6 of the cutting mechanism is performed by a switch (not shown). When the coupling half and the gear 21 interact, the coupling half 26 is separated from the gear 20 by means of a rocker arm rigidly connected to the switch.

The cutting process is carried out as a result of the interaction of the cutting edges 11 and I2 of the knife 6 with the holes of the grids 7 and 8. The raw material through the screw feeder 3 enters the inter-blade space of the knife 6 between the receiving 7 and output 8 grids and fills it due to the difference in throughput of the grids . When the knife 6 is rotated, the cutting process is carried out by the interaction of the cutting edges 11 of the knife 6 with the corresponding halves of the holes of the grids 7 and 8. When the knife 6 is reversed, the raw material that fills the blade gap 6 of the knife 6 presses on the dark side of the cutting edges 11 and reduces them together. In so doing, the cutting edges 12 are rotated 90, and the cutting process is carried out by

the interaction of the cutting edges 12 of the knife 6 with the other halves of the circles of the openings of the gratings 7 and 8.
