Process for producing feed-grade zinc lactate

Abstract

The invention discloses a process for producing feed-grade zinc lactate. The process flow of process comprises quantitative addition of all raw materials in a reaction kettle, direct chemical reaction, cooling, centrifugal separation, drying and packaging to obtain a finished product; in the process flow of centrifugal separation, the separated mother solution is transferred to a storage tank; and then the mother solution in the storage tank is transferred to the reaction kettle for chemical reaction, so that the mother solution is recycled. In the method, the mother solution in the producing process is recycled, so that the process saves cost, avoid discharging three wastes, and contributes to environmental protection; the feed-grade zinc lactate produced by the method can be used in animal feed additives and be widely used in breeding production, is high in purity, contains 98.3 percent of zinc lactate and 21.6 percent of zinc content which are both higher than the state standards; and therefore, the process has the advantages of low cost and high benefit and contributes to the sound and fast development of the state breeding industry.

Description

Technical field [0001] The invention relates to a production process of zinc lactate, in particular to a production process of high-purity feed-grade zinc lactate mainly used as feed additives, and belongs to the production field of zinc lactate. Background technique [0002] Iron, zinc, and copper are all trace elements necessary for animals. As constituents and cofactors of enzymes, they affect various metabolic activities of the body. Among them, zinc is more related to the activities of more than 200 enzymes in animals, regulating and controlling the structure and function of these enzymes. It has been proven that trace elements play a role in animals in the form of organic matter or chelate, rather than ionic state. However, almost all trace element additives traditionally used to feed animals are inorganic salts. The metal ions released by inorganic salts during the digestion process easily combine with other substances in the intestine (such as phytic acid, oxalic acid, ...

AI Technical Summary

Problems solved by technology

However, zinc lactate currently on the market is only used in food production, and has never been used in animal feed production, and because of technical defects in the production process, the purity and zinc content of zinc lactate finished products are not high enough; at the same time, Because the mother liquor after the reaction is directly discharged during the production process, the utilization rate of raw materials is reduced, the production cost is increased, and the environment is damaged
