The invention relates to processing meat, poultry and fish and to mechanical engineering. Whilst processing beef and pork meat, the flesh is stripped from biggest bones only. The mechanical stripping of muscle flesh from other bones, tendons and cords is carried out when the meat is hashed by the cutting unit of a specific meat hasher. A hashed meat separator incorporated into the hasher cutting unit degasses a hashed meat layer-by-layer. In addition, said separator makes it possible to remove all types of rough inclusions, large vessel parts, different membranes and structures combining muscle cells into beams. Minced meat exhibits a low calcium content. The prime separation meat products are accumulated and afterwards are hashed by means of the cutting unit of the same hasher, wherein the inventive method consists in additionally stripping muscle tissues and stripping connective tissues, in chapping cellular tissues and, finally, in separating the hashed product. The thus produced minced product consisting mainly of connective tissues is used for substituting meat in the form of a food additive for food products. The feeding unit and cutting members of the meat hasher are intentionally adapted for processing meat lumps, including meat on bones and entire poultry or fish carcasses. The cutting and feeding units of the hasher exclude tissue crushing, breaking and wearing. The head (17) of the hasher cutting tool comprises receiving (25), intermediate (26) and cutting-separating (27) grids and also one-sided knives (18-22) which are adjacent thereto and mounted in such a way that three straight-through chambers (28, 29, 30) are formed. Said grids and knives are used without intermediate sharpening. The cutting tool of the specific meat hasher is provided with a system for automatically pressing knives against the grids, thereby reducing the wear thereof and making it possible to substantially decrease the iron content in the minced meat. The shape of wearable knife blades and the grids is modified in such a way that formation of gaps between the interacting surfaces thereof is excluded. The edges of the cutting elements of the knives and grids is continuously renewable. Said set of inventions makes it possible to mechanise the more labour consuming and unhealthy processes used for meat, poultry and fish processing, to increase the labour productivity, to sharply improve the quality of food products, reduce the cost thereof and to ease the meat hasher maintenance.
