Problems solved by technology

This method mainly removes glucosinolates in defatted rapeseed meal, but cannot remove phytate and tannin, and the detoxification time is usually as long as several days, takes up a lot of space, and the detoxification effect is greatly affected by the environment. Infection with miscellaneous bacteria leads to detoxification failure, etc.

Embodiment 1

[0031] A kind of specific method step of the detoxified concentrated rapeseed protein powder manufacturing process for feed is as follows:

[0032] (1) Initial detoxification by medium pressure steam

[0033] The defatted rapeseed meal after leaching rapeseed oil is used as the raw material, first crushed by a grinder and passed through a 20-mesh screen, and those that have not passed the screen are returned to the grinder and crushed again. The powder passing through the sieve is collected to prepare defatted rapeseed meal powder. Then according to the weight of defatted rapeseed meal powder: the ratio of soft water volume ratio is 1: 0.5, add soft water in the defatted rapeseed meal powder, place on 100 mesh screens after stirring evenly, then place it in the bottom filled with water In the high-pressure vessel, the water level is below the screen on which the defatted rapeseed meal is placed. After sealing, heat up to the water at the bottom of the high-pressure container...

Abstract

A manufacturing process of detoxicating concentrating rapeseed protein powder for feed use relates to a detoxication method of rapeseed dregs. The invention takes the defatted rapeseed dregs as raw materials, and then obtains the completed products through middle pressure steam detoxicating and dilute hydrochloric acid detoxicating, separation, ethyl hydrate detoxicating, drying, comminuting and centrifugal separation in sequence. Because the invention has simple process, low water use and alcohol amount and can realize waste water purification and ethanol recovery, so it has low fabricating cost, effective detoxification effect and effective removal of glucosinase, phytic acid and tannin (three toxic harmful substance) in the rapeseed dregs. The products produced by the inventive process has high product quality and comprehensive utilization. So that the invention can be widely used as detoxicating feed raw material and raw materials of phytic acid and tannin.

Description

1. Technical field [0001] The invention belongs to the technical field of defatted rapeseed meal processing, in particular to a detoxification method for defatted rapeseed meal. 2. Background technology [0002] Rapeseed is one of the main oil crops in my country, with an annual output of 5 million tons, accounting for 38.3% of the world's total output. Rapeseed is processed under modern industrial production conditions, usually 35-40% rapeseed oil and 50-55% defatted meal can be obtained. Rapeseed oil is one of the main edible oils in our country, and it is also used to make fatty acids, glycerin, etc. Rapeseed defatted meal has rich sources of raw materials, high nutritional value, and contains 35-40% protein. Rapeseed protein is a high-quality protein, the amino acid composition conforms to the FAO / WHO recommended model value, and the content of sulfur-containing amino acids and lysine is relatively high. The PER value of rapeseed protein is higher than other vegetable...
