Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice milling machine. Background Art

[0002] Rice milling is a process of peeling and whitening rice. The mechanical force generated by mechanical equipment is used to peel and whiten the rice. The mechanical equipment used is called a rice milling machine. The rice milling machine mainly uses the collision and friction between rice and rice sieve to make it rough and white.

[0003] Chinese Patent 202321590717.7 provides a rice milling machine for rice processing, including a box body, a feed hopper is arranged on the top of the box body; the rice milling assembly is arranged in the box body and corresponds to the position of the feed hopper; the sub-screening assembly is arranged below the rice milling assembly, including a sub-screening frame slidably arranged in the box body, a filter plate arranged at an angle at the bottom of the sub-screening frame, a discharge port is arranged on the side of the sub-screening frame close to the inclined lower end of the filter plate, and a driving member is arranged on one side of the sub-screening frame to move the sub-screening frame repeatedly. The utility model solves the problem of poor separation effect of rice husk and rice grains in the prior art. By setting a sub-screening assembly, the sub-screening frame moves repeatedly and its bottom is inclined, the rice husk falls into the bottom of the box body after being filtered by the filter plate, and the rice grains slide out of the discharge port to complete the separation of rice grains and rice husk. Compared with the use of a fan, the rice husk will not slide out with the rice grains and can directly fall into the bottom of the box body, thereby improving the separation effect of rice husk and rice grains.

[0004] However, although the above rice milling machine can separate rice grains from rice husks when processing rice, the effect is poor, and the separated rice grains are often mixed with a lot of dust. Therefore, a rice milling machine is proposed to solve the above problems. Utility Model Content
