Description
Technical Field
[0001] The present application relates to the technical field of rice polishing machines, and in particular to a rice polishing machine capable of reducing broken rice. Background Art
[0002] Due to the influence of seasonal climate or long-term storage, some rice may have different colors or become moldy, resulting in various grades of rice. As people's living standards continue to improve, their taste for rice has improved. In order to improve the edible quality, commercial value and storage time, rice needs to be polished to remove the bran or debris adhering to the surface of the rice, making the rice grains crystal clear and smooth.
[0003] Currently, a Chinese patent publication with publication number CN216137274U discloses a rice polishing machine capable of reducing rice breakage, comprising a housing, which is vertically arranged. The rice polishing machine, capable of reducing rice breakage, comprises a material dividing and polishing mechanism. When a motor drives a rotating rod to cause a polishing column and a polishing cylinder to polish rice, the rotation of a disc drives two curved plates to rotate in a material guide ring groove, so that the two curved plates effectively control the amount of rice passing through the material control groove, preventing a large amount of rice from entering between the polishing column and the polishing cylinder at the same time, causing friction and squeezing between the rice, thereby solving the problem of a high rice breakage rate during rice polishing. Furthermore, a screening mechanism is provided, in which the rotating rod drives a control rod to rotate using the action of a bevel gear, causing the control rod to strike a screen plate, thereby increasing the screening speed. Furthermore, a material collecting cover is provided to guide the rice to the center of the screen plate, and the top center of the screen plate is positioned upward, thereby improving the screening effect of the screen plate on the rice.
[0004] In actual use, it is found that the existing rice polishing machine cannot feed rice at a uniform speed, which easily causes rice to accumulate during feeding, thereby resulting in the rice not being fully polished, and there is a problem of affecting the polishing quality of rice. Therefore, we propose a rice polishing machine that reduces broken rice to solve the above problem. Utility Model Content
