Description

Technical Field

[0001] This utility model relates to the technical field of rice processing equipment, and in particular to a dust removal device for rice processing. Background Technology

[0002] Rice processing is the process of removing the husk and bran from rice grains. Rice grains consist of the husk, bran, germ, and endosperm. The purpose of rice processing is to separate the endosperm from the other parts with minimal breakage, producing rice with better eating quality. Rice processing is divided into three steps: cleaning, hulling, and milling.

[0003] In the prior art, such as the rice processing equipment disclosed in patent publication number CN220590125U, which is used to polish the surface of rice, a polishing machine is included. The top side of the polishing machine is equipped with a feeding end, and the side wall of the polishing machine is equipped with a discharging end. An anti-overflow component is installed inside the feeding end, and an adjustment component is provided inside the discharging end. This utility model reduces the occurrence of rice overflowing from the feeding end when the polishing machine is working by using the anti-overflow component, thereby playing a role in preventing overflow. At the same time, the use of the adjustment component allows the amount of rice discharged from the discharging end of the polishing machine to be adjusted according to the situation, thereby improving the practicality of the polishing machine.

[0004] After the rice is hulled, in order to ensure the quality of the rice, it is necessary to remove the dust from the outside of the rice to make the rice grains whiter and cleaner. Currently, existing dust removal devices generally use a suction mechanism to adsorb the dust attached to the outside of the rice. Although this method can remove the dust, a large amount of dust still adheres to the outside of the rice, resulting in poor dust removal effect. Therefore, it needs to be improved.
