PROBLEM TO BE SOLVED: To prevent unpolished rice from scattering while eliminating dust from the unpolished rice of an unpolished rice lifting machine by strong sucking air. SOLUTION: A dust collector 36 is attached to the unpolished rice lifting machine 6 discharging the unpolished rice sorted in a mixed rice sorting part 3 to the outside of the lifting machine to eliminate dust from the unpolished rice. The dust collector 36 is connected to the beginning side of a dust collecting passage 37 and the suction part of a sucking fan 16 of a hulled-rice air sorting part 2 is connected to the terminal side of the dust collecting passage 37, and a middle drift part 42 is installed in the middle part of the dust collecting passage 37. An opening/closing valve 46 is installed at the bottom part of the middle drift part 42 which opens at the time of storing the predetermined amount of unpolished rice. The unpolished rice dropped to the bottom part of the middle drift part 42 drops to the unpolished rice lifting machine 6 to be recovered therein by opening of the opening/closing valve 46 if the predetermined amount of unpolished rice stores.
