Raw material paddy flows through the downflow gutter 5 and enters the wind selection room 4. In the wind selection chamber 4, air enters through the air inlet 36 by the action of the suction fan 6, and the rice husks pass through the gripping pipe 7 and are discharged from the outlet 8. Immature grains hit the partition plate 11 and are transferred to the immature grain receiving trough 10.
and is taken out by a conveyor. The mixed rice of brown rice and unhulled rice enters the rice receiving trough 9 and is carried by a conveyor to the entrance of the thrower 14, and by the action of the thrower 14 enters the grain sorting section hopper 13 of the grain sorting section 12. The grain enters the rotary separator 17 through the outlet 25 of the grain sorting section hole/<-13.

Brown rice is paddy receiving net 22
The brown rice flows through the bottom of the approximately V-shaped collection spiral receiving trough 20 and is transferred to the discharge trough 21 by the screw conveyor 19, from which it flows down the brown rice flow down trough 15 and enters the rotating drum 18. On the other hand, the unhulled rice falls along the paddy receiving net 22 of the collection spiral receiving trough 20 of the substantially square shape, and is again collected in the four parts 24 of the rotary separator 17 (7). This accumulated unhulled rice is sent to the loading hopper 1 from the unhulled rice outlet 26 of the unhulled rice discharge gutter 16. Adjustment of the angle of the v$v-shaped recovery spiral receiving gutter 20 is performed when there is a large amount of unhulled rice in the mixed rice. The rice accumulates in the four parts 27 of the rotating cylinder and is transferred from the bottom to the top of the rotating drum 18, and accumulates on the top surface of the bottom plate 31 of the screw conveyor 30. The screw conveyor 30 rotates from the rotating shaft 29, and the finished rice drains into the gutter 33. The rice passes through the finished rice flow down gutter 34, passes through this, accumulates in the finished rice flow down gutter 35, and is discharged to the outside by a conveyor. In this way, the recovery rate of brown rice is extremely high, and by providing the paddy catch net 22 of the roughly V-shaped collection spiral catch gutter 20, the unhulled rice is allowed to fall along the paddy catch net, and The angle can be adjusted depending on whether there is a lot of unhulled rice to be added to the mixed rice or not. In other words, the angle θ in Figure 2 is set when there is a lot of unhulled rice (θ is made smaller, and when there is less unhulled rice, θ is made larger, so that the recovery rate of brown rice is improved.
According to the present invention, a rotary separator 17 having an approximately ■-shaped collection spiral receiving trough 20 is provided in the grain sorting section lz of the hulling machine 2 having the hulling chamber 2, the winnowing chamber 4, and the grain sorting section 12.
