PURPOSE: To always exhibit the best performance in a rice husker and a rice milling machine by passing exhaust through a rocking sorting devise from the blower of a rubble takeout machine and sucking this exhaust through a sorting air path of the rice husker from an exhaust path by a blower for rice husking and discharging the exhaust to the outside.

CONSTITUTION: A rice husker 6 is provided to the upper part of the inside of a mechanical body 1. The grains of paddy are husked between the husking rolls 2, 2. Sorting wind is sucked by a blower 3 for rice husking and passed through a sorting wind path 4. While the husked grains of paddy are allowed to fall on a sorting shelf 5, these are sorted into unpolished rice and chaff. A rocking sorting device 7 which receives supply of unpolished rice is provided to the downside of the rice husker 6. Air blasting is performed to the rocking sorting machine 7 from a blower 8. While unpolished rice is floated, a rubble takeout machine 9 rocks and sorts both unpolished rice and rubbles admixed therewith by rocking and sorting. Sorting wind is pass ed through the rocking sorting device 7 and exhausted to an exhaust path 10. The terminal side of this exhaust path 10 is faced and provided to the starting end side of the sorting wind path 4. As a result, the rice husker 6 and a rice milling machine always exhibit excellent performance.
