Description

The invention relates to the meat industry and can be used to produce fat.

A device for draining fat is known. masses.

A disadvantage of the known device is the impossibility of processing bone material in it.

It is also known a bone shredder device comprising a cylindrical housing enclosed in a casing with knives and a blade disc mounted on the vertical drive shaft.

The disadvantages of the known device are large energy losses due to the friction of the ground bone on the inner wall of the body, the uneven distribution of the supplied bone along the periphery of the disk and the inability to carry out the fat sweating simultaneously with the grinding.

Closest to the invention is a device for grinding raw materials and heating fat used in a plant for the production of fat. The device comprises a stationary cylindrical body with a loading neck, inside of which a cylindrical drum is coaxially arranged to form an annular gap, having a forming gap along the entire height of the body. There are vertical knives inside the slots. Inside the drum there is a disk rotatably in a horizontal plane on which vertical blades are symmetrically mounted. Steam is supplied through the nozzles to the annular gap. In the lower part of the housing there is a port for removal of fat mass.

The drawbacks of the device are low intensity of bone grinding, considerable friction energy loss of the ground bone against the walls of the knife drum, and uneven distribution of the bone material around the periphery of the disk when it is loaded.

The purpose of the invention is to intensify the process by reducing the forces of friction against the inner surface of the drum.

The goal is achieved by the fact that the drum is installed with the possibility of rotation in the direction opposite to the rotation of the disks. F - itct m g, about central

parts mounted distribution cone.

The proposed design of the device provides counter-rotation of the knife drum and disc with simultaneous impact on the raw bone material of live steam, which significantly increases the speed of cutting bone and extracting bone fat. As the cutting speed is required in part due to the counter-rotation of the knife drum, the centrifugal forces acting on the ground bone mass are reduced. Consequently, friction strength

5 the inner wall of the knife drum.

By means of a distribution cone, an even distribution of the crushed bone mass along the periphery of the disc is achieved.

0The drawing shows vertical

section of the device.

The device includes a loading neck 1, a stationary body 2, a drum 3 with a hollow shaft rotating on supports 4,

5 on which four knives 6 are symmetrically fixed in the longitudinal slots 5, and forming, together with the stationary body 2, an annular gap 7 for treating the crushed bone with live steam, a disk 8 with a blade 9 and a shaft 10 rotating on supports 11, two electric motors 12 , two klinoremennye transfer 13. a pipe for removal of fat 14, a pipe for steam

15, distribution cone 16, bed 5 17.

The device works as follows.

When the electric motor 12 is turned on through the V-belt drives 13, the drum 3 with the blades 6 and the disk 8 with the blades 9 rotate counter-rotating. The bone to be processed is fed through the loading neck 1 to the distribution cone

16, which distributes bone to disk 8 5 to reduce the unbalance masses on the disk. Under the action of centrifugal force, the bone moves to the periphery of the disk 8 and presses against the walls of the rotating drum 3. The bone is pulled by blades 9 is crushed by the knives 6. The cut chips of the bone are ejected through the slots 5 into the annular gap 7, into which sharp steam flows through the pipe 15. Under its influence, fat is released from the crushed bone, which, together with the condensate and the small fraction of the bone, is fed for further processing through the nozzle 14.

The use of a device for the production of fat with counter-rotating knife blade and blade disc allows

to intensify the process of grinding the bone and trapping fat, reduce the friction energy loss of the ground bone on the inner walls of the knife drum, shorten the time of high temperature impact on the bone material and improve the quality of the fat.

The fat recovery rate increased from 76-84 to 87-92% of the initial bone content.
