Screening device for rice processing

Abstract

The invention relates to a screening device for rice processing. The screening device comprises two symmetrical bases, an angle adjusting mechanism used for pouring rice is arranged above the position between the two bases, a screening mechanism used for screening the rice is arranged above the angle adjusting mechanism, and a rice conveying mechanism is arranged above the screening mechanism. According to the screening device for rice processing, through the arrangement of the rice conveying mechanism, the screening mechanism and a dust treatment mechanism, rice screening is conducted in a closed environment, and therefore the situation that dust generated in the rice screening process is expanded to the outside can be avoided; and on the other hand, the dust diffused in a box body is conveyed into a shell through a dust discharging pipe, the dust generated in the rice screening process is adsorbed and purified through the shell and the like, and therefore the dust can be effectively prevented from being diffused to the outside, and the health of workers and the regional environment are effectively protected.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a screening device for rice processing. Background technique [0002] Rice is food made from rice after cleaning, husking, rice milling, and finished product finishing. Rice is rich in carbohydrates and protein. People in southern my country generally eat rice as a staple food; at present, rice processing generally uses It is operated by machinery, and different rice has different technological processes. The conventional technological process of rice includes raw material processing, rice milling, cooling, bran removal, screening and finished products. Screening is an important step in the rice processing process. It is related to the quality of finished rice; [0003] At this stage, the purpose of screening rice is to remove broken rice and bran powder in the rice, so as to ensure the cleanliness and quality of the finished rice. In the prior art, the screening of rice m...

Problems solved by technology

[0003] At this stage, the purpose of screening rice is to remove broken rice and bran powder in the rice, so as to ensure the cleanliness and quality of the finished rice. In the prior art, the screening of rice mainly uses vibrating screening equipment, namely The rice is screened through the sieve under the action of the vibrating motor, but the existing vibrating screening equipment has the following problems when screening the rice: when the rice is screened, the bran powder and dust in the rice are easily The reason for the diffusion of air under the action of vibration is that, on the one hand, most of the existing vibration screening equipment is an open structure, which does not have restrictions on dust, etc., and dust, etc., easily diffuses from the inside of the equipment to the outside. On the one hand, the existing vibrating screening equipment does not have the structure for processing dust, and cannot promptly and effectively process the dust generated during screening; the diffuse dust not only causes smoke and dust to diffuse in the working environment, but also poses a hazard to the health of the staff (such as causing pneumoconiosis and other diseases), and it is easy to cause regional environmental pollution, so it is particularly important to deal with dust in time during the rice screening process. In view of this, we propose a screening device for rice processing
