Description

TECHNICAL FIELD

[0001] The utility model relates to rice processing related field, and specifically, relate to a rice milling and polishing device. BACKGROUND

[0002] With the vigorous development of economy and the significant improvement of people's living standards, the yield of rice also presents a steady growth trend. As one of the important staple foods of human beings, rice occupies a pivotal position in the diet culture. It is not only an indispensable delicacy on the daily dining table, but also the main source of energy and nutrition for people. From paddy to finished rice, it needs to go through many fine and complex processes.

[0003] The existing rice milling and polishing device still has some problems when in use:

[0004] In the traditional rice milling and hulling process, although the suction fan is generally used to suck away light impurities such as rice hulls, it is often difficult to effectively remove larger and heavier impurity particles. These impurity particles that are difficult to be sucked away not only continuously interfere with the normal processing of rice during milling, reducing the milling efficiency;

[0005] And, the existing rice polishing machine relies on manual water spraying during operation to ensure that the rice surface is uniformly watered. This process not only consumes time and effort, but also easily leads to uneven spraying due to human factors, thereby affecting the polishing effect and the quality of the final rice.

[0006] Therefore, we improve it and propose a rice milling and polishing device. UTILITY MODEL CONTENT
