In the kneading process, brown rice near the inner wall of the middle part of the kneading cylinder 2 may be accumulated and clamped, as a further proposal of the invention, the surface of the kneading ball 16 is fixedly connected with a stirring rod 32, and the end part of the stirring rod 32 is rotatably connected with a roller 33;

at the in-process of kneading, it can drive stirring rod 32 and rotate to knead ball 16 rotation, and stirring rod 32 can will knead the brown rice stirring in the section of thick bamboo 2, avoids kneading a section of thick bamboo 2 and is close to the brown rice of inner wall and can pile up the card and live, and the gyro wheel 33 of stirring rod 32 tip can carry out preliminary roll extrusion with the brown rice that is close to kneading a section of thick bamboo 2 inner wall, is favorable to making follow-up separation of corn husk more easily.

A method for separating rough rice for processing rice comprises the following steps:

the method comprises the following steps: firstly, starting a rice huller, and then putting the rice huller and the winnowed brown rice into a separator;

step two: then the falling amount of the brown rice can be controlled by the blanking mechanism, and then the brown rice can fall into the rolling mechanism;

step three: the rolling mechanism can fully roll the unhulled brown rice to ensure that the brown rice is hulled;

step four: then the brown rice falls into the separation mechanism to separate the brown rice from the rice husks;

step five: finally, the fully hulled brown rice is obtained.
