Description

Technical Field

[0001] The utility model belongs to the technical field of rice polishing devices, and in particular relates to a rice polishing device. Background Art

[0002] Rice is a finished product made from paddy rice after processes such as cleaning, husking, milling and finishing. After shelling, its surface needs to be polished and ground.

[0003] Polishing devices are disclosed in the prior art, such as a rice polishing device disclosed in CN202121206428.3, which includes a polishing roller and a polishing cylinder that can rotate freely. The polishing roller is placed in the polishing cylinder and can rotate freely. The inner wall of the polishing cylinder is provided with power teeth, and the polishing roller is connected with driving teeth and also includes transmission teeth, which are respectively engaged with the power teeth and the driving teeth; a pulley is provided on the outer wall of the polishing cylinder, and the pulley is connected to the driving device through a belt. It has a simple structure, good polishing effect and high polishing efficiency.

[0004] It is undeniable that the rice polishing device disclosed in the patent can indeed achieve the above-mentioned technical effects, but it still has certain shortcomings.
