Abstract

The invention provides a device and method for preparing rice protein through magnetic field-assisted electrostatic separation, and belongs to the field of rice protein. The method comprises the following steps that S1, rice residues are ground in a grinding machine and then classified in an air classifier, and a fine powder material is obtained; s2, air flow is provided by a feeding system, so that the fine powder material particles are carried in the air flow and enter a friction pressurizing pipe to carry out friction electrification charging on the fine powder material; and S3, after the fine powder material is electrified, the fine powder material enters a separation chamber under airflow conveying, and after the electrified fine powder material is subjected to the action of an electric field formed by the two copper electrodes, a magnetic field formed by the two permanent magnets and a gravity field, rice protein particles are separated. The method is simple in process, remarkable in effect, low in cost, free of pollution and waste, free of use of volatile organic solvents, toxic substances and the like, environmentally friendly and safe and has wide development and market application prospects.

Description

technical field [0001] The invention relates to the technical field of rice protein, in particular to a device and method for preparing rice protein through magnetic field-assisted electrostatic separation. Background technique [0002] Animal protein has become an indispensable food for human beings due to its excellent edible quality and nutritional content. However, raising animals in an energy-intensive manner requires large amounts of arable land, water, grain and other crops. Among them, the conversion of edible vegetable protein has become a new life trend. As a plant-based protein, rice protein is rich in nutrients and comprehensive, and it is also a good source of protein in terms of nutritional quality. Therefore, it is of great value to isolate rice protein from rice. [0003] Traditional methods for obtaining vegetable protein components mainly include wet separation and dry separation. Among them, wet separation requires the use of a large amount of water (5...
