PURPOSE:To strengthen dust pick-up and improve the working environment of a rice huller by connecting dust pick-up porous components on the removing section side and selection case side to a dust pick-up fan to suck the dust around a rice huller through an upper dust pick-up passage. CONSTITUTION:A dust pick-up fan 28 is disposed in a support cylinder 27, and a dust removing pipe 20 is connected with an exhaust outlet section 28a of the dust pick-up fan 28, while the terminal side of the dust removing pipe 29 is set next to a dust removing cylinder 6. Slits or small openings 27a, 27a... are constituted on the whole peripheral section of the support cylinder 27, and a dust pick-up inlet 28b of the dust pick-up fan 28 are so constituted as to pass the surrounding air through said slit or small openings 27a, 27a... and flow through therein to improve the working environment. Thus, dust is picked up and removed from a dust pick-up porous component 25 of a rice hull reduction hopper 23 and a dust pick-up porous component 25 of a mixed rice hopper 9 through the mixed rice hopper 9 and a pick-up dust passage 30 provided on the upper side of the bran reduction hopper 23, and picked up to the dust pick-up fan 28 and removed therefrom.
