Problems solved by technology

However, since cottonseed cake contains a small amount of toxic substance - gossypol, it cannot be effectively utilized
At present, a lot of work has been done on the detoxification of cottonseed processing, such as further cooking of cottonseed cake, hot steam injection, solvent re-leaching, alkaline treatment, microbial fermentation, etc. Due to the high cost, it has not been produced in a large scale continuously

Embodiment Construction

[0008] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0009] A method for producing cottonseed protein wet meal by leaching, the production steps are:

[0010] a: put the cottonseed protein material embryo 8 with uniform thickness, firmness, less powder formation and low impurity content into the storage box 1, and transport it to the oil extractor 4 with the buried scraper conveyor 2 and the closed auger 3; The height of the material layer in storage box 1 is not less than 500mm. When it is lower than the required height, immediately stop injecting 6# solvent into the oil extractor 4; the sealing auger 3 requires the material to be effectively closed when it enters the oil extractor 4 function to prevent the 6# solvent gas from overflowing from the feed port in the oil extractor 4.

[0011] b: Use a solvent pump to add 6# solvent 9 to the oil extractor 4 to extract the oil, spray the solvent 9 evenly at...

Abstract

A process for preparing the wet cotton seed protein dregs by leaching-out method includes such steps as loading the raw cotton seed protein material in storage tank, extracting oil in solvent, dephenolizing in methanol, and removing part of solvent.

Description

Technical field: [0001] The invention relates to a production method for plant protein extraction, in particular to a production method for producing cottonseed protein wet meal by leaching. Background technique: [0002] my country is a large cotton-producing country, and the cottonseed cake resource is very rich. The protein content in the cottonseed cake is about 40%. Therefore, the cottonseed cake, like the soybean cake, is a kind of high-quality vegetable protein with rich sources. However, since cottonseed cake contains a small amount of toxic substance-gossypol, it cannot be effectively utilized. At present, a lot of work has been done on the detoxification of cottonseed processing, such as further cooking of cottonseed cake, hot steam injection, solvent re-leaching, alkaline treatment, microbial fermentation, etc. Due to the high cost, it cannot be produced continuously on a large scale. Invention content: [0003] In order to solve the shortcomings of the existi...
