Method and device for treating branched chain amino acid waste liquid

Abstract

The invention discloses a branched-chain amino acid waste liquid treatment method and device in the technical field of branched-chain amino acid processing.The treatment method comprises the steps that branched-chain amino acid concentrated waste liquid and a composite metal salt solution are mixed according to the volume ratio of (2-4): 1, a reaction solution A is obtained, the reaction solution A is heated to 60-80 DEG C under nitrogen protection, and a reaction solution B is obtained; and carrying out pressurized jet treatment on the reaction liquid A for 2-4 hours to obtain a reaction liquid B, and sequentially carrying out filtering treatment and spray drying treatment on the reaction liquid B to obtain the powdery compound amino acid chelate. In the process of producing the amino acid metal chelate by using the branched chain amino acid waste liquid as the raw material, the recycling effect of the compound amino acid in the waste liquid is optimized through pressurized jet treatment, the chelating efficiency of the compound amino acid in the waste liquid and metal ions is effectively improved, and the produced amino acid metal chelate is excellent and stable in quality.
