Production method of compound amino acid produced with feathers

Abstract

The invention discloses a production method of compound amino acid produced with feathers, and belongs to the technical field of compound amino acid production. The method comprises a cystine section, a leucine section and a compound amino acid section, wherein a secondary alkali neutralization mother liquid is fed into the leucine section for producing leucine; the leucine section comprises the steps that the secondary alkali neutralization mother liquid is subjected to concentration, condensation, ammonolysis, decoloration and ammonium neutralization, then leucine is obtained, and a filtrate in the condensation procedure is fed into the compound amino acid section; the compound amino acid section comprises the following steps that liquid ammonia is added into the filtrate in the condensation procedure, the pH value is adjusted to 4.4-5.3, and then a slurry is obtained; the slurry is fed into a spray drying tower for drying, wherein the temperature of hot air is 240-270 DEG C; tail gas and dust generated by spray drying are fed into a cyclone dust collector for treatment, and then the product is obtained; the tail gas of the cyclone dust collector is fed into a spray dust-removal device for cycle spray treatment, wherein the cycle spray liquid is a slurry with the pH value of 4.4-5.3.

Description

technical field [0001] The invention relates to the technical field of compound amino acid production, in particular to a method for producing compound amino acids from feathers, in particular to a method for co-producing compound amino acids with at least one cystine, leucine and the like. Background technique [0002] Amino acids are the basic substances necessary for the movement of human life. There are many types of compound amino acids, and the raw materials are mainly plant-based and animal-based. Plant-based compound amino acids are made from natural high-protein plants, using advanced biochemical engineering technology to extract and separate various amino acids from plants. Animal-type compound amino acids are made from various high-protein animal bodies (such as hair, feathers, etc.), processed by microbial fermentation or acid-base hydrolysis, and then spray-dried. [0003] The types of compound amino acids mainly refer to the quantity of amino acids contained ...

AI Technical Summary

Problems solved by technology

[0007] The existing compound amino acid production line has a single function, and can only obtain one or two products, and the compound amino acid has many uses, such as feed additives, chemical raw materials or other uses, while the existing technology can only obtain products of one specification

At the same time, the yield of the existing compound amino acid is low, the output is 350-400kg per ton of wool, the moisture content is greater than 3.5%, and the amino acid content is less than 20% by dry weight
