The meat m is conveyed forward between the guide plates 22 and 22 by the belt 7, and first the presser chain 19,
19, the left and right sides are pressed downward, and in this state, the movable blade 33, which reciprocates left and right, removes grease on a predetermined arcuate surface. In that case, as the movable blade 33 moves left and right, the meat m tends to shift left and right, but the fixed blade 32 prevents this and continues scraping on a predetermined arcuate surface at a predetermined position. Meat m with cuts made in fat f is presser chain 19,
It is released from 19 and transported forward, and the fat is separated.

The band-shaped fixed blade 32 in the present invention may be nearly rigid. Further, the bending state can be formed into various shapes depending on the shape of the fat layer of the meat to be processed.

(Effect of the invention) According to the skin, fat, etc. scraping device of the present invention, the skin, oil, etc.
It is possible to efficiently remove the skin and fat from meat with fat, etc., and if the band-shaped fixed blade is bent to correspond to the desired surface for removing skin, fat, etc., the elastic band-shaped blade can be used. The movable blade can reciprocate from side to side in a bent state corresponding to the same surface to remove skin, fat, etc. as the fixed blade, thereby making it possible to perform scraping on the desired surface to remove skin, fat, etc. It can be done.
