How Meat Grinder Works-Alice

March 14, 2022

When working, the material is turned on first and then discharged. Due to the gravity of the material itself and the rotation of the screw feeder, the material is continuously sent to the reamer for shredding. Because the screw pitch of the screw feeder should be smaller in the back than in the front, but the diameter of the screw shaft is larger in the back than in the front, which produces a certain squeezing force on the material, which forces the chopped meat to be discharged from the holes on the grid plate. .

When used in the production of canned lunch meat, the fat meat needs to be coarsely ground and the lean meat needs to be finely ground. There are several different sizes of holes in the grid, usually 8-10 mm in diameter for coarse stranding and 3-5 mm in diameter for fine stranding. Thick and finely stranded gratings are 10-12 mm thick. Due to the larger diameter of the coarse twist and the easier discharge, the speed of the screw feeder can be faster than that of the fine twist, but the maximum is not more than 400 rpm. Generally 200-400 rpm. Because the total area of the holes on the grid plate is certain, that is, the discharge volume is certain, when the feeding screw rotates too fast, the material will be blocked near the cutter, resulting in a sudden increase in the load, which has a bad influence on the motor.

The cutting edge of the reamer is installed along the transfer of the cutter. The reamer is made of tool steel, and the blade must be sharp. After a period of use, the blade will become dull. At this time, the blade should be replaced with a new blade or re-ground, otherwise the cutting efficiency will be affected, and even some materials will not be chopped and discharged, but will be discharged by After extrusion and grinding, it is discharged into a slurry, which directly affects the quality of the finished product. According to the research of some factories, the quality accident of serious fat precipitation in canned luncheon meat is often related to this reason.

After assembling or replacing the reamer, the tightening nut must be tightened to ensure that the grid does not move, otherwise the relative movement between the movement of the grid and the rotation of the reamer will also cause the effect on the material and refining. The reamer must be in close contact with the grid, otherwise it will affect the cutting efficiency. The screw feeder rotates in the machine wall. It is necessary to prevent the surface of the screw from colliding with the machine wall. If a slight collision occurs, the machine will be damaged immediately. However, their gap should not be too large, which will affect the feeding efficiency and extrusion force, and even cause the material to flow back from the gap, so the processing and installation requirements of these parts are relatively high.
