Description

[Detailed description of the invention] The present invention relates to a meat cutting machine for frozen meat.

Generally, in a meat cutting machine, a conveyor is provided on a carriage and moves in a direction perpendicular to the reciprocating motion of the carriage, and the mass to be cut is placed on the conveyor. The meat cutter is configured so that the meat is held down by toothed rollers, and the mass is intermittently transferred by the cutting thickness by the reciprocating movement of the carriage, and then cut by the rotating round blade. When cutting frozen meat on a conveyor, the surface of the frozen meat becomes slippery due to freezing, which causes the meat to slip on the conveyor, making it difficult to cut to a uniform thickness. The present invention aims to provide a meat cutting machine for frozen meat that eliminates these drawbacks, and is capable of extruding chunks without using a conveyor.
