The invention discloses a rice hulling device. The rice hulling device is composed of a power motor, a machine frame, a transmission system, a feeding hopper, a rice hulling device body, an air blowing device and a rice-bran separating device; the transmission system comprises a driving wheel, a transmission wheel, a transmission belt and a transmission shaft; the lower end of the feeding hopper is provided with an L-shaped feeding pipe, and the L-shaped feeding pipe, the rice hulling device body and the air blowing device coaxially and sequentially communicate with one another, are fixed and are jointly mounted on the machine frame; the transmission wheel is fixed at the tail end of the transmission shaft, the transmission shaft sequentially penetrates through the center of the air blowing device and the center of the rice hulling device body, the front section of the transmission shaft is arranged in the transverse section of the L-shaped feeding pipe, and fan blades of the air blowing device and an impeller of the rice hulling device body are all fixed on the transmission shaft; and the rice hulling device body comprises a cylindrical shell and a valve fixed to the feeding side in the shell, and an annular rubber disc is arranged on the inner side of the valve. Compared with a traditional rice hulling machine, the rice hulling machine has the advantages that manufacturing is simpler, operation is more convenient, the integrity of rice grains can be higher, and the nutritional ingredients of the rice grains can be retained to the maximum extent.
