FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, particularly to feed production. The method comprises defrostation and coarse and fine grinding of meat and fish raw material. Meat and fish raw material after defrostation before coarse grinding is loaded into the press and compacted to the density which is minimum, but sufficient for penetration of the knife blade into the raw material: meat raw material under pressure of 1.56-1.95 MPa is compacted until its density reaches 1230-1247 kg/m3, and fish raw material under pressure of 2.73-3.51 MPa until its density reaches 1272-1291 kg/m3. Dense meat and fish raw material is unloaded and fed for coarse grinding followed by fine grinding. The cell juice which is extracted from the raw material under compacting is collected in a tank for further processing.
EFFECT: use of invention enables to improve the quality of preparation of feed mixtures.
