Description

TECHNICAL FIELD

The typical rice milling process mainly has cleaning, separation of husked rice, rice milling, rice rubbing and the like several processes.

[0003] After searching, it is found that the application No. for CN202121196134.7, the name is a dust removal device for rice production, the application puts forward that the processing machine will have dust after long-term use, the rice will also contain dust after processing, and the dust removal of rice is also one of the important processes, but the dust removal process of rice is relatively complex, and the dust filtered out is not treated by absorption and discharged, which will cause environmental pollution. The problem, by setting a dust removal pipeline between the two frame bodies, the dust removal pipeline includes a dust removal pipe and a static dust collection rod arranged in the dust removal pipe, so that when the rice falls into the dust removal pipe, the static electricity generated by the static dust collection rod will attract the dust carried on the rice. This not only greatly reduces the complexity of rice dust removal, but also avoids directly discharging the dust in the rice into the air environment, greatly improves the environmental friendliness of the whole equipment, and is conducive to large-scale production. However, the application uses the static dust collection rod for static dust removal in actual use, the dispersion degree of rice is low when passing through the static dust collection rod, and the dust or dust is difficult to pass through the rice and contact with the static dust collection rod due to the mutual shielding between the rice, resulting in low dust removal efficiency. At the same time, the rice particles are not large and the quality is also light, which can also be easily absorbed by the static dust collection rod, so as to cause poor dust removal and separation stability of the rice, affect the working efficiency, and the static dust collection rod also needs to be frequently powered off and cleaned. The working continuity and simplicity are not good, and further improvement can be made.
