Abstract

The invention relates to the technical field of production of copper glutamate, and particularly discloses a production process of feed-grade copper glutamate. The production process is characterized in that a wet synthesis process is adopted, copper and glutamic acid react in a solution, a copper glutamate solution is obtained by controlling the reaction temperature and the reaction time, a copper glutamate product is obtained through cooling crystallization, drying is performed to remove surface moisture, and then screening is performed to remove large-particle products to obtain the feed-grade copper glutamate. According to the invention, 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, heavy metals and the like can meet the quality requirements of feed-grade copper glutamate; only heating and stirring are needed in the production process, and complex operations such as ultrasonic treatment and the like are not needed, so that 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 copper glutamate production, in particular the production process of feed-grade copper glutamate. Background technique [0002] Copper is one of the essential trace elements for animals, and it participates in animal hematopoiesis, metabolism, growth and reproduction, and disease resistance. Animals have a nutritional requirement of copper at 5-8mg / kg, but since it was discovered in 1945 that high copper can significantly improve the growth performance of pigs, 200-250ppm (quality) high copper (in the form of Copper ion meter), high copper has the effect of coagulating protein, reducing the proliferation of microorganisms, stimulating the secretion of neuropeptide Y (NPY), thereby promoting animal feed intake, improving the activity of digestive enzymes, and ultimately improving growth performance. Therefore, the use of high copper in pigs has become the "habit" of many nutritionists since the 1950s. ...
