Problems solved by technology

[0003] However, the existing production techniques for synthesizing zinc glutamate are limited to laboratory synthesis, and the synthesis methods all adopt microwave synthesis or organic solvent extraction, which consumes a lot of energy and pollutes, and is difficult to apply to actual production. Therefore, a new method is proposed. A kind of production technology of feed grade zinc glutamate

Abstract

The invention relates to the technical field of zinc glutamate production, and particularly discloses a production process of feed-grade zinc glutamate, which comprises the following steps: adopting a wet synthesis process, adopting zinc and glutamic acid to react in a solution, obtaining a zinc glutamate solution by controlling the reaction temperature and the reaction time, obtaining a zinc glutamate product by cooling crystallization, through drying, removing surface moisture, and screening to remove large-particle products, thereby obtaining the feed-grade zinc glutamate. The process is low in energy consumption, green and environment-friendly, and does not generate substances polluting the environment, and various indexes such as product content and heavy metals can meet the quality requirements of feed-grade zinc glutamate; as only heating and stirring are needed in the production process, complex operations such as ultrasonic are not needed, and the equipment cost is low; the synthesis process is carried out in water, no harmful by-product is generated, mother liquor can be recycled, organic solvent extraction is not needed, the process is green and environment-friendly, post-treatment is simple, and no three wastes are generated; and the synthesis process is environment-friendly, economical and efficient.

Description

technical field [0001] The invention relates to the technical field of zinc glutamate production, in particular to the production process of feed grade zinc glutamate. Background technique [0002] The use of zinc glutamate instead of other zinc sources has been proven to have higher safety and antibacterial activity, and reduce the toxic and side effects of high zinc on animals. Chinese patent, authorized announcement number: CN101785534B, discloses zinc glutamate or its derivatives The application of zinc glutamate or its derivatives as animal growth-promoting feed additives is mentioned in its technical proposal. Zinc glutamate has low water solubility, strong acid resistance and high Bioavailability, using zinc glutamate as a growth-promoting feed additive has higher safety and antibacterial activity than other zinc sources (including zinc oxide, basic zinc chloride and zinc glycinate, etc.), and the amount of zinc ions added It can be reduced by 80%-90%, which can redu...
