Description

Screening equipment for rice processing

technical field

The utility model relates to a screening device for rice processing.

Background technique

Rice is the finished product of paddy after cleaning, husking, rice milling, finishing and other processes. The cleaning process is to use appropriate equipment, through appropriate technological processes and proper operation methods, to remove all kinds of impurities mixed in the rice, so as to improve the quality of the finished rice, and to use magnets to remove iron nails and iron filings in the rice. To ensure production safety. The hulling process is to use a rubber roller huller or an emery huller to remove the chaff of the rice and separate the chaff from the brown rice. The rice milling process is to use a rice mill to grind and rub the brown rice to separate the cortex and endosperm, and then to brush the rice, remove the bran, crush the rice, and dry the rice, so that the rice of the required grade can be obtained. Modern new rice also uses processing technologies such as color sorting, winnowing, germ removal and dust removal, sterilization and pest control, antibacterial, oxygen barrier, enzyme inhibition, bionic packaging, etc. to make the rice more hygienic, safe, delicious and nutritious, with less loss. During rice processing, the organic rice treated by the polishing machine often contains rice grains of different particle sizes, which makes the color of the organic rice worse and affects the selling price of the organic rice; in addition, the fine particles and rice flour contained in the organic rice are Granular or other shapes of rice dirt are formed after encountering water, which affects the taste of organic rice. Most of the rice grading and screening devices in the prior art are pipeline-type multi-stage screening devices with complex structures, many parts and components, and a high probability of device failure, which affects normal production work; There will be a lot of broken rice after husking. At this time, practical vibration equipment is needed to screen the rice and filter out the broken rice.
