Abstract

The invention belongs to the technical field of amino acid biological manufacturing, and particularly relates to a multi-effect continuous deamination evaporation system and a valine deamination method using the multi-effect continuous deamination evaporation system. The characteristics of valine mash are studied, a set of multi-effect continuous deamination evaporation system and a valine deamination method using the system are designed and developed, the multi-effect evaporation technology and the continuous deamination technology are ingeniously and effectively combined, and multi-effect evaporation deamination is performed by using the most energy-saving method. The system is used for continuous deamination of the valine mash, the content of ammonia in the valine mash can be greatly reduced, steam condensate, dilute ammonia water and strong ammonia water are classified and recycled, energy conservation and environmental protection are achieved, and the comprehensive utilization value of the ammonia water is improved. Meanwhile, the valine mash extraction and purification process is easier to implement, and the method is high in product yield, good in quality and low in production cost, and has incomparable advantages.

Description

technical field [0001] The invention belongs to the technical field of amino acid biomanufacturing, and in particular relates to a multi-effect continuous deamination evaporation system and a method for deamination of valine by using the same. Background technique [0002] The chemical name of L-valine (L-valine) is L-α-aminoisovaleric acid. Valine is an important part of living organisms and plays an important role in many aspects such as the regulation of material metabolism and information transmission in the living body. . Valine is one of the eight essential amino acids (lysine, threonine, tryptophan, arginine, leucine, isoleucine, phenylalanine, and valine), and one of the three One of the branched-chain amino acids (leucine, isoleucine and valine), its application range is very wide, and it is widely used in human nutrition additives, feed additives, condiments, medicines, pesticides and health products, etc. . [0003] At present, the production of valine is mainl...
