Brown rice processing device and processing method thereof

The invention provides a brown rice processing device. The brown rice processing device comprises a peeling device, a feeding assembly and a transfer channel. In order to better control rice grains ina material receiving box to be conveyed to a discharge port and finally flow into a turnover material frame, when the rice grains need to be loaded into the turnover material frame, an auger structure is started to work, and the auger structure enables the rice grains in a containing area to be collected towards a middle area, move towards the rear side direction along the middle area and be discharged into the turnover material frame through the discharge port; and through observation of people or sensing of a weight sensor, after a certain weight is reached, the auger structure stops working, that is, continuous feeding into the turnover material frame is stopped. Therefore, the auger structure plays a role of valve control equivalently, and in the actual production process, the rice grains in the containing ar
