System for preparing compound amino acid from waste protein through microwave acidolysis

Abstract

The invention discloses a system for preparing compound amino acid from waste protein through microwave acidolysis. The system comprises a spiral extrusion separator and a crude fiber temporary storage pool, wherein the spiral extrusion separator is connected with a microwave hydrolysis reaction kettle through a first electric diaphragm pump; the microwave hydrolysis reaction kettle is connected with a hydrochloric acid cylinder and an organic liquid temporary storage tank through pipelines; the microwave hydrolysis reaction kettle is connected with a plate-and-frame filter press through a second electric diaphragm pump; the plate-and-frame filter press is connected with a hydrolysate temporary storage tank through a first submerged anti-corrosion pump; the hydrolysate temporary storage tank is connected with a third electric diaphragm pump, an alkali liquor cylinder and a neutralizing cylinder through pipelines; the third electric diaphragm pump is connected with a second submerged anti-corrosion pump through a ceramic ultrafiltration membrane filtering assembly; and the second submerged anti-corrosion pump is connected with a spray drying tower and an amino acid concentrated solution temporary storage tank through pipelines. Through cooperative use of the above units, the pressure of the market demand for protein can be relieved, and protein resources which cannot be directlyutilized can be fully utilized.

Description

technical field [0001] The invention relates to the related technical field of amino acid extraction, in particular to a system for preparing compound amino acids by microwave acid hydrolysis of waste protein. Background technique [0002] In recent years, the shortage of protein resources in my country has become serious. Taking soybeans as an example, the average demand for soybeans in my country from 2016 to 2018 was 110 million tons. In recent years, although my country's overall soybean production has shown an upward trend, the average annual soybean production in my country is less than 18 million tons, and the average annual import volume is more than 90 million tons. The average import dependence is as high as 80%, and the import value is about 360 billion yuan. RMB. [0003] These imported soybeans are mainly eaten by humans as soybean products or added to feed by animals in the form of soybean meal. Since protein is a macromolecule with a molecular weight of tens o...
