Bran screening equipment with good screening quality for rice processing

Abstract

The invention discloses bran screening equipment with good screening quality for rice processing. The bran screening equipment comprises a limiting rod, sliding blocks, limiting pipes, stirring rods, a lifting plate, a limiting column, moving rods, a screen, a baffle, a swing rod, a feeding pipe, a moving box body, a motor, a working plate, a pneumatic telescopic cylinder, a discharging pipe, a supporting rod, a bottom plate, a collecting box, a supporting column, a partition plate, a corrugated pipe, a screening box body, a discharge plate, a limiting plate, a rotating disc and a fixed box body. According to the equipment, through the arranged stirring rods, grain is conveniently stirred, meanwhile, rice husks remaining in the grain are screened through reciprocating motion of the installed screen, then the quality of screened rice grains is improved, the screening box body is driven to rotate by the installed pneumatic telescopic cylinder, then the included angle between the bottom end of the screening box body and the horizontal plane is adjusted, and screened rice husks can enter the collecting box through the corrugated pipe, so that the collecting efficiency of the rice husks is improved, and meanwhile, the health of workers is protected.

Description

technical field [0001] The invention relates to the technical field of rice processing equipment, in particular to chaff sieving equipment for rice processing with good sieving quality. Background technique [0002] Rice is the finished product of rice after cleaning, husking, rice milling, finishing and other processes. The germ and aleurone layers of rice contain nearly 64% of rice nutrition and more than 90% of the nutrients needed by the human body. It is the main food of the southern people. After the rice is husked, it needs to be sieved, which is easy and convenient. The rice grains are separated from the rice husks, but the existing bran sifting equipment is insufficient in the process of sieving bran, which may easily cause rice husks to remain in the rice grains, thereby reducing the quality of sieving the rice grains. The sifted rice husks tend to remain inside the screening box, which is not conducive to the collection of the sieved rice husks, which requires ma...

Problems solved by technology

The germ and aleurone layers of rice contain nearly 64% of rice nutrition and more than 90% of the nutrients needed by the human body. It is the main food of the southern people. After the rice is husked, it needs to be sieved, which is easy and convenient. The rice grains are separated from the rice husks, but the existing bran sifting equipment is insufficient in the process of sieving bran, which may easily cause rice husks to remain in the rice grains, thereby reducing the quality of sieving the rice grains. The sifted rice husks tend to remain inside the screening box, which is not conducive to the collection of the sieved rice husks, which requires manual collection, which increases labor intensity. The dust is easy to inhale into the body, thus endangering the health of the collectors
