High-quality fine rice efficient polishing device

Abstract

The invention discloses a high-quality fine rice efficient polishing device. The high-quality fine rice efficient polishing device comprises a cylinder body, a feeding hopper, a bran and dust screen cylinder body, a polishing bottom screen, a broken rice screen conical cylinder and a rice collecting bin which is fixed to the inside of the cylinder body, the bran and dust screen cylinder body is fixedly arranged at the upper end inside the cylinder body, annular dust cleaning brushes are distributed at the middle lower end of the inner wall of the bran and dust screen cylinder body, a bran anddust cavity is arranged between the bran and dust screen cylinder body and the inner wall of the cylinder body, an air inlet hood and a bran suction hood which are communicated with the bran and dustcavity are arranged on outer walls of the two sides of the cylinder body respectively, the polishing bottom screen is fixedly arranged at the bottom of the bran and dust screen cylinder body in a sealing mode, a polishing chamber enclosed by the bran and dust screen cylinder body and the polishing bottom screen is filled with polishing pills, and the broken rice screen conical cylinder is arrangedinside the cylinder body below the bran and dust screen cylinder body. The high-quality fine rice efficient polishing device is reasonable in structural design, simple in overall design structure, good in work safety performance and good in polishing effect, the generation of broken rice is reduced, and the separating effect and separating efficiency of the broken rice and rice are drastically improved at the same time.

Description

technical field [0001] The invention relates to the technical field of rice polishing equipment, in particular to a high-quality and efficient rice polishing device. Background technique [0002] Paddy becomes brown rice after hulling, and brown rice becomes rice after removing most of the cortex and a part of germ. There is also a small amount of bran powder on the surface of the rice grains of large white rice, which affects the appearance quality, storage and taste of the rice. Therefore, this part of the bran powder needs to be removed through the "polishing" process. Polishing is one of the key processes in cleaning rice processing. Since polishing can remove the bran powder on the surface of rice grains, proper polishing can gelatinize the starch on the surface of rice grains and present a certain brightness. The appearance effect is good, and the commodity value is improved. The current popular polishing is wet polishing, that is, adding an appropriate amount of wat...

Problems solved by technology

[0003] Because rice polishing is a very common process in existing grain processing, rice polishing machines are widely used in grain processing enterprises; existing polishing machines use polishing rollers to polish rice, and polishing rollers to polish rice There will be a certain rolling force during the process, which is easy to produce broken rice, and it is easy to cause uneven polishing during polishing. Part of the surface of the rice grain will be over-polished, while part of the surface will not be polished.

[0004] The existing rice polishing machine has a reasonable structural design, and one end of the rotating shaft is suspended in the air, which increases the risk of damage to the equipment during operation; the direct contact between the stirring blade and the inner wall of the screen often causes a large amount of broken rice to be generated, and also increases the operating resistance of the equipment; The separation efficiency of polished broken rice and rice is low, the separation effect is poor, and it is difficult to improve the overall quality of rice
