Background The household rice mill is used as a convenient small household appliance, and can directly dehulling and processing the harvested grains into edible polished rice or further grinding and processing the brown rice so as to improve the taste and meet the requirements of consumers on fresh rice. In the rice milling process, grain shelling and brown rice grinding are two core processes, and the requirements of the two processes on the processing rotating speed are obviously different. The husking of the grains needs a moderate rotating speed, so that the shell is broken and separated, the rice grains are prevented from being broken, and the brown rice is ground at a higher rotating speed so as to sufficiently remove rice bran layers, and the polished rice with fine taste is obtained. However, there are significant drawbacks to the design of existing household rice mills. The motor usually runs at a fixed rotation speed, and the same rotation speed is used for husking grains or grinding brown rice, so that the processing effect is poor. If the rotating speed is lower, the grain husking is not thorough, the polished rice after the brown rice is ground has more residual rice bran and has rough taste, and if the rotating speed is higher, the broken rice rate is high when the grain husking is performed, and the brown rice is excessively ground, so that nutrition is lost. The design of the fixed rotating speed can not adapt to the requirements of different processing stages, and the processing quality and the user experience of the rice are seriously affected.
