The utility model relates to agriculture and can be used in the production of protein and vitamin supplements from bone and nonedible meat material, bird feathers, etc. A method is proposed for producing meat and bone meal, in which raw material comprising tissue and bones is consecutively ground, cooked to a pulp, hydrolyzed, sterilized, degreased and dried. In the method, the mass of ground raw material is fed into a thin-layered boiler and hydrolyzer, in a layer of not more than 30 mm, where it is cooked to a pulp at a temperature of 180-250°C for 90-300 sec., after which said boiled and hydrolyzed product is fed into a vacuum drying unit where it is dried at a temperature of 110°C for 90 min, and then the dried product is fed to an extractor where the dried product is extracted with a hexane solvent at a temperature of 55-60°C for 45-60 min, the meat and bone meal is separated from molasses, and the meat and bone meal is dried in a toasting oven with simultaneous removal of hexane solvent vapours, which are condensed and returned to the process, wherein the molasses are separated from the hexane solvent by boiling off the hexane solvent, which is then condensed and returned to the process.
