PURPOSE:To ensure the discharge of remaining unhulled rice from an unhulled rice conveyance gutter with a screw, by continuing the operation of the screw even after the conveyance of unhulled rice and injecting air up through the bottom of the gutter so that the remaining unhulled rice in the gutter is forced to irregularly rebound on the screw and the bottom of the gutter. CONSTITUTION:Even after the conveyance of unhulled rice, the rotation of a conveying screw 4 is continued. At the same time, a blower 6 is started to send a wind into a blowing chamber 5. The wind jets into an unhulled rice conveyance gutter 1 through the wind holes 7 of its bottom so that the unhulled rice remaining in the gutter is blown onto the conveyance screw 4 and guided in the direction of conveyance by the screw 4 while rebounding irregularly. As a result, the remaining unhulled rice is discharged at 3. Since the unhulled rice is caused to rebound irregularly, it is entirely discharged. |
