A kind of compound amino acid powder spraying system and the production method of amino acid powder

Abstract

The invention discloses a compound amino acid powder spraying system and an amino acid production method, belonging to the technical field of amino acid production. The system includes a regulating tank, a spray drying tower, a material recovery device and a spray dust removal device connected in sequence. The regulating tank is connected with the leucine section; the material recovery device includes a dust removal induced draft fan, a large cyclone dust collector, a small cyclone dust collector and a Two-stage small cyclone dust collector, the tail gas outlet of the spray drying tower is connected with the air inlet of the large cyclone dust collector through pipelines, one side of the discharge port, the first-stage small cyclone dust collector, the second-stage small cyclone dust collector and the large cyclone The air inlet of the dust collector is connected sequentially through pipelines, and the dust removal induced draft fan is installed between the air outlet of the large cyclone dust collector and the spray dust removal device, and the discharge of the spray drying tower and the discharge of the first-stage small cyclone dust collector are adjusted. tank; the spray dust removal device is connected to the adjustment tank through pipelines, and the circulating spray liquid of the spray dust removal device is the slurry of the adjustment tank.

Description

technical field [0001] The invention relates to the technical field of compound amino acid production, in particular to a compound amino acid powder spraying system and an amino acid production method, in particular to a method for co-producing compound amino acids such as at least one cystine and leucine, and a high-yield, High-quality and dust-free compound amino acid powder spraying system. 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...

AI Technical Summary

Problems solved by technology

[0007] The existing compound amino acid production process is as follows: the feather hydrolyzate or the mother liquor for producing other amino acids is prepared to make a compound amino acid slurry, the compound amino acid slurry passes through a spray drying tower, then passes through a cyclone dust collector, and finally passes through a water washing tower to remove the exhaust gas. Processing, the applicant found the following problems when preparing compound amino acids according to the above process: the drying workshop has a lot of dust, the waste of raw materials is large, the product yield is low, and some products are wasted in the drying, dust removal and tail gas treatment processes.
