Comprehensive rice polishing machine for rice bran powder recycling and rice bran powder separation method

Abstract

The invention discloses a comprehensive rice polishing machine for rice bran powder recycling and a rice bran powder separation method. The comprehensive rice polishing machine comprises a discharging pipeline arranged at the lower end of a mechanical shell, the discharging pipeline is divided into an anti-adhesion section, a rice bran powder recycling section and a classified output section from top to bottom, and a plurality of arc-shaped plates used for breaking rice adhesion are arranged at the two sides of the inner wall of the anti-adhesion section correspondingly; the arc-shaped plate located at the lowermost end of the anti-adhesion section is used for reducing the flow speed of polished rice, and the rice bran powder recycling section is provided with a rotary recycling unit movably rotating along the rice bran powder recycling section and an air pressure component installed on the opposite face of the rotary recycling unit; and the air pressure component blows rice bran powder in the polished rice into the rotary recycling unit by utilizing the set stable wind speed, the rotary recycling unit movably rotates to enable the rice bran powder to fall along one pipeline of the classified output section, and the rice without the rice bran powder falls along the other pipeline of the classified output section. By means of the comprehensive rice polishing machine and the rice bran powder separation method, complete separation of the rice bran powder and the rice is guaranteed, and cross contamination of the rice bran powder and the rice after separation is prevented.

Description

technical field [0001] The invention relates to the technical field of rice polishing, in particular to a comprehensive rice polishing machine for recycling bran powder and a method for separating bran powder. Background technique [0002] Treating the surface of the rice grains can make the rice grains crystal clear and form a very thin gel film on the surface of the rice grains. This process is called polishing. The main function of the rice polisher is to remove the bran powder adhering to the surface of the white rice. After the rice surface is polished, there is a layer of waxy protective layer, which can not only prevent the adhesion of rice bran or the falling off of rice flour in the production, storage, transportation and sales of rice, ensure the cleanliness of rice, but also improve the quality and commodity value of finished rice , which is beneficial to the storage of rice, keeps the freshness of rice, and improves the eating quality of rice. [0003] The work...

Problems solved by technology

[0005] The purpose of the present invention is to provide a comprehensive rice polishing machine and bran powder separation method for recycling bran powder, so as to solve the problem that the polished rice particles in the prior art are easily stuck together by bran powder, so the rice is directly transported In a negative pressure environment, the complete separation of rice and bran powder cannot be achieved, and the technical problem of cross-contamination is likely to occur when the bran powder and rice are exported after separation
