A rice hulling machine comprising a rice-polishing section for whitening rice, which comprises a brown rice area and a mixed rice area formed by the brown rice and paddy in the mixed rice being drifted on the board by the rocking action of a rocking sorting plate. The feature is that the spillage is supplied to the rice polishing section and the paddy spilled from the paddy area is returned to the depuffing section.

[0005]

With this configuration, the mixed rice of brown rice and paddy that has passed through the depuffing / selecting section is supplied to the rocking / sorting section, and the rocking / sorting plate swings to cause uneven distribution and rocking. The brown rice layer is generated in the brown rice area, the paddy layer is formed in the swaying paddy area, and the mixed rice layer is formed in the mixed rice area between the brown rice area and the paddy area. Brown rice and mixed rice flowing out from the brown rice area and the mixed rice area are supplied to the rice-polishing section, and the rice-polishing section is supplied with an appropriate amount of paddy.
The paddy is removed at the beginning of the polishing process, and the dehulled rice husk serves as a medium to promote the polishing process to white rice, and the paddy flowing out from the paddy field is returned to the removing wind selection section and is removed again. It is done and is selected.
