Rice bran screening device for rice processing and its working method

Abstract

The invention discloses a rice bran screening device for rice processing and a working method thereof. The device comprises a frame, and the frame is provided with a discharging mechanism, a feeding mechanism, a first screening mechanism, a second screening mechanism and a control mechanism. a feeding mechanism; the discharging mechanism includes a material distribution box, a feeding funnel is arranged above the material distribution box, and a first feeding port is formed at the upper end opening of the feeding funnel; on the left outer wall of the feeding funnel A connecting rod is fixedly connected, the other end of the connecting rod is fixed with a motor mounting seat, a driving motor is installed in the motor mounting seat, a stirring shaft is installed on the right end of the driving motor, and the stirring shaft extends into the material distribution box and It runs through the right side wall of the material distribution box; a stirring gear block is arranged on the left side of the material distribution box on the stirring shaft, and a number of material distribution rods are arranged in the material distribution box on the stirring shaft, and the ends of the material distribution rods are provided with There is a brush; the device improves the screening efficiency of brown rice and avoids the waste of rice bran.

Description

technical field [0001] The invention relates to the technical field of rice bran screening equipment, in particular to a rice bran screening device for rice processing and a working method thereof. Background technique [0002] Rice is the finished product of rice after cleaning, husking, rice milling, finishing and other processes, and rice bran is mixed in rice. Rice bran refers to the brown layer outside the brown rice kernel that is removed during the process of rice processing. Its composition is different, it is composed of pericarp, seed coat, nacelle and aleurone layer. With the whitening process, the rice bran is peeled off the rice germ layer by layer. Rice bran is a by-product of rice rolling, containing 64% of rice. Important nutritional components, the annual output of my country is about 10 million tons, rice bran is an excellent resource with great development value, using appropriate equipment, through appropriate technological processes and proper operation me...

AI Technical Summary

Problems solved by technology

[0003] Rice is obtained through a series of processing of rice. In the process of processing rice into rice, rice bran will be produced from brown rice to polished rice, and then there will be a certain amount of broken rice in the rice bran, and the broken rice will be mixed in rice bran. Not only does it affect the follow-up processing of rice bran, but also because broken rice can be eaten, if broken rice is mixed in rice bran and used as feed, it will also cause food waste, so it is necessary to separate the broken rice in rice bran; however, the existing The separation device is not completely separated, and the structure is complicated, and it is inconvenient to disassemble and maintain
