Embodiment Construction

[0006] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0007] Depend on figure 1 Given, the present invention is realized by the following steps:

[0008] 1. Bran separation: about 5% of broken rice grains, mud, stones and other sundries are mixed in the rice bran raw material, and these sundries are screened and separated to lay a good foundation for the later stage of production;

[0009] 2. Granulation: send the screened and separated rice bran into a granulator to process into bran grains;

[0010] 3. Drying: heat the granulated rice bran granules, and control the temperature at 80-90°C to dry the rice bran granules. After drying, the moisture in the granules is controlled at 7.5-8.5%, thus laying a good foundation for the rice bran leaching process. Base;

[0011] 4. Leaching: The dried rice bran particles are run at a speed of 120 minutes per rotation, leached, and sprayed ...

Abstract

The invention relates to a production method for extracting and separating protein from rice bran, and effectively solves extraction and separation of protein from the rice bran so as to meet healthy diet requirements from people. The technical proposal is that the method comprises the following procedures: (1) bran and crushed rice separation, (2) granulation, (3) drying, (4) leaching, (5) low-temperature precipitation, (6) primary extraction of defatted cake, (7) primary separation, (8) secondary extraction, (9) secondary separation, (10) acid deposition, (11) curd separation, (12) neutralization, (13) sterilization, (14) pressurization, spray drying and (15) packaging. The method has the advantages of realizing integrated scale production from rice bran to protein extraction from the rice bran, providing good technology and new method for deep-processing of the rice bran, effectively solving technical problem of industrialized protein separation from the rice bran, meeting human protein requirements in diet, and has great economic and social benefits.

Description

1. Technical field [0001] The invention relates to the field of chemical industry, in particular to a production method for extracting and separating protein from rice bran. 2. Background technology [0002] Rice bran is a cheap and nutritious by-product of rice processing, with an annual output of more than 14 million tons of rice bran in my country, which is a renewable resource with a large quantity and a wide range. Rice bran is rich in nutrients, and the protein content in defatted rice bran can be as high as 18%. At present, most rice bran is still used as animal feed, which is a serious waste of resources. Therefore, it is of great practical significance to seek new protein resources from rice bran and increase the added value of rice bran. Rice bran protein is recognized as a high-quality plant protein. Its essential amino acid composition is balanced and reasonable. Among them, the content of lysine is relatively high, and the biological value of rice bran protein ...
