Rice brushing machine for flexibly removing rice bran

Abstract

The invention provides a rice brushing machine for flexibly removing rice bran. The rice brushing machine comprises a case, a hopper, brush rollers, rice bran powder sifters, a transmission wheel setand collecting bins. The hopper is arranged on the case, the brush rollers comprise axially rotating rollers and brushes covering the peripheries of the rollers and are parallel pairwise, brushes on the two parallel brush rollers are abutted to each other, the rice bran powder sifters sleeve the peripheries of the brush rollers, two ends of each rice bran powder sifter are fixedly connected to theinner wall of the case through connecting rods, the transmission wheel set comprises a driving wheel, driven wheels, a steering wheel, a tensioning wheel and a conveying belt, the conveying belt is tensioned on the transmission wheel set in a closed manner, the collecting bins comprise rice bran powder collecting bins and honed rice collecting bins, the rice bran powder collecting bins are positioned below the rice bran powder sifters, and the honed rice collecting bins are positioned below the centers of the pairwise parallel brush rollers. Compared with the prior art, the rice brushing machine for flexibly removing the rice bran can effectively remove rice bran chippings, cost is reduced, excessive polishing of unpolished rice is prevented, the germ-remained rate is increased, and broken rice rate is reduced.

Description

technical field [0001] The invention relates to the technical field of grain milling, in particular to a rice brushing machine for removing chaff attached to rice grains after rice milling. Background technique [0002] Paddy becomes brown rice after husking, and brown rice becomes rice after removing most of the cortex and part of the 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. [0003] 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. [0004] At present, the popular polishing is wet polishing, that is, adding an appropriate amount of water during the polishi...

AI Technical Summary

Problems solved by technology

However, during the rice polishing process, most polishing equipment over-polishes the rice, resulting in a serious loss of nutrients in the rice and causing waste. Therefore, it is now necessary to rely on equipment that can effectively remove the rice bran on the surface of brown rice and reduce over-polishing of brown rice.
