Problems solved by technology

[0003] Alcoholic mash is the waste produced in the process of alcohol production. For every ton of alcohol produced, 13-15 tons of mash is produced. The chemical oxygen demand (COD) is as high as 50000mg / L, and the biological oxygen demand (BOD) is as high as 30000mg / L, which greatly exceeds the discharge standards stipulated by the state, such as direct discharge into sewage for treatment, which greatly increases the load and cost of sewage treatment

Abstract

The invention provides a preparation method of plant composite protein. The preparation method comprises the following steps: (1) after precipitating alcohol mash in an alcohol workshop through a precipitation tank to obtain alcohol mash residues with the concentration of 8 to 12 Baume degrees; (2) after mixing the precipitated alcohol mash residues in step (1) and sugar residues which are obtained by a filtering procedure in a starch sugar production process and are conveyed through a packing auger, then conveying a mixture into a feeding opening of a pipe bundle drier; drying through the pipe bundle drier; (3) conveying a dried material in step (2), wheat gluten, corn germ and protein powder through the packing auger; blending through a mixing machine according to the mass part; conveying into a pulverizer through the packing auger and pulverizing; (4) sieving a crushed material in step (3) through a 60-mesh sieve, wherein an obtained undersize matter is the plant composite protein.According to the preparation method provided by the invention, after the precipitated and centrifuged alcohol mash residues and the byproduct sugar residues of starch sugar are mixed and dried, a mixture is blended with the corn germ with abundant nutrients, the protein powder and the wheat gluten and the requirements of animals on protein, fat and crude fibers can be met.

Description

technical field [0001] The invention relates to the field of protein preparation, in particular to a method for preparing plant composite protein. Background technique [0002] Plant protein feed is a kind of protein feed. Plant feed (including by-products) with CP≥20% and CF<18% ​​belongs to plant protein feed. The growth, development, reproduction and maintenance of life of animals require a large amount of protein, which is supplied through feed. If the protein supply cannot meet the needs, the pigs will become thin, their growth will stagnate, their production performance will decline, they will be prone to disease, and even die. The necessity and irreplaceability of protein nutrition makes protein feed occupy a particularly important position in pig production. Plant-based protein feed is high in content and rich in nutrition, which is beneficial to the absorption and utilization of breeding animals, and stimulates growth and reproduction to varying degrees, which ...
