Abstract

The invention discloses a fish feed processing method. Since 0.8 percent of peptide concentrates are added in a raw material formula, the nutrient value of the fish feed can be increased; pre-drying is performed after raw material curing, drying temperature is 50 DEG C and drying time is 15min. Since raw materials are cured by adopting steam and the increase of water in the cured raw materials is adverse to particle formation during granulation, pre-drying is performed to control water content in the raw material to facilitate the particle formation during granulation; secondary curing is performed after granulation, curing temperature is 65 DEG C, curing time is 30min, and secondary curing can guarantee the high curing degree of the fish feed to facilitate digestion of fish; air cooling is adopted, air speed is 0.8m / s and such means can quickly cool particles; fish extract oil is used as sprayed grease, can increase the nutrient value of the fish feed on one aspect and can take a waterproof effect to the feed on the other aspect.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a fish feed processing method. Background technique [0002] Fish feed is what feeds the fish. Its main components are protein, fat, vitamins and minerals. Protein is an important nutrient for the survival of fish and shrimp, and an important component of the cells, tissues and organs of the body. The normal growth of fish requires protein in sufficient quantity, easy to digest and absorb, and suitable ratio of various amino acids in the feed. When the intake of protein is insufficient for fish, the growth will be slow, the immunity of the body will be reduced, and the protein with appropriate ratio of various amino acids. When the protein intake of fish is insufficient, the growth is slow, the immunity of the body is reduced, the tissue renewal is slow, the wound healing is poor, and the disease is easy. If you take too much protein, the protein that cannot be digested and uti...
