Abstract

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. The present invention studies the characteristics of valine mash, designs and develops a set of multi-effect continuous deamination evaporation system and a method for using the system to carry out valine deamination. This invention combines multi-effect evaporation technology, continuous The deamination technology is cleverly and effectively combined, and the most energy-saving method is used for multi-effect evaporation deamination. Using this system for continuous deamination of valine mash can not only greatly reduce the ammonia content in valine mash, but also classify and recycle steam condensed water, dilute ammonia water, and concentrated ammonia water, which is not only energy-saving and environmentally friendly, but also The comprehensive utilization value of the ammonia water is improved, and at the same time, the extraction and purification process of the valine mash is easier to implement, and the product yield is high, the quality is good, and the production cost is low, which 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...
