rice polisher

Abstract

The invention discloses a rice polishing machine, which includes a frame, an electric control box, a feeding assembly, a polishing chamber and a discharging assembly; the polishing roller includes a water mixing section, a pre-polishing section and a fine polishing section arranged in sequence along the axis The water mixing section includes the first roller body and inclined ribs. The cross section of the inclined ribs perpendicular to the axis is trapezoidal, and the inclined ribs form a helical angle with the axis; the pre-polishing section includes the second roller body and straight ribs. The section is trapezoidal, and the straight ribs are parallel to the axis; the fine polishing section includes the third roller body and a polishing block, and the section of the outer surface of the polishing block perpendicular to the axis is involute; the discharge assembly includes a discharge port set at the end of the screen The bushing, the bushing at the discharge port includes a screen interface that is docked with the tail end of the screen, and the shape of the inner wall of the screen interface matches the shape of the outer shape of the screen. In the rice polishing machine of the present invention, the outer surface of the polishing block of the fine polishing section of the polishing roller is an involute curved surface, and the interface of the sieve is in the same shape as the sieve, thereby reducing broken rice and energy consumption.

Description

technical field [0001] The invention relates to the technical field of grain processing equipment, in particular to a rice polishing machine. 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 working process of the rice polishing machine is as follows: the white r...

AI Technical Summary

Problems solved by technology

[0004] However, due to the flaws in the design of the traditional polishing machine, it is easy to produce broken rice during the rice polishing process, which not only affects the quality of the final product, but also increases the process of removing broken rice
