During this fluid transfer, the brown rice in the sliding rice falls one by one into the recesses 15 and falls from a high position, and enters the brown rice receiving trough 17.
After the rice that has been rubbed in the sorting tube increases in the ratio of paddy as it is transferred in the axial direction, it becomes almost only paddy on the discharge side of the sorting tube, and is returned to the paddy supply hopper 10 in the hulling mechanism C and recycled again. The shupu is performed.

On the other hand, the brown rice receiving trough 17 in the upper sorting tube
The coarsely sorted brown rice enters the supply side of the lower sorting cylinder, and as it repeatedly flows through the sorting cylinder and is transferred to the discharge side forming a fluidized bed, only the brown rice is transferred to the receiving side. After being carefully sorted to enter the gutter 17, the brown rice thrower 13
While being taken out of the machine, the scraped rice discharged from the discharge side of the lower sorting tube joins the scraped rice conveyor 2 and is subjected to the sorting operation again.

When the hulling work is completed, both operating rods 2
By pushing down the wheels 8 and 29, both wheels 26 and 27 protrude from the lower surface of the machine base 20, and the entire huller sorting machine A is tilted. Since the groove-shaped drop openings 33 of the brown rice receiving gutter 17 and the fallen rice transfer gutter 19 are opened, all of the residual brown rice in each of the brown rice receiving gutter 17 and the fallen rice transfer gutter 19 is transferred to both the brown rice receiving gutter 17 and the fallen rice transfer gutter 19. It is discharged all at once into a separate cylinder.

On the other hand, both sorting tubes in the rotary sorting mechanism D,
Due to the overall inclination of the huller sorter A,
Since the discharge side is inclined to be lower than the supply side, by continuing the rotational drive by the motor M for a while in this state, the residual brown rice in the lower sorting tube of both the sorting tubes is removed. The residual brown rice discharged into the lower sorting tube is sent from the discharge side of the lower sorting tube to the sliding rice conveyor 2 as the lower sorting tube rotates, and then transferred to the sliding rice conveyor 2 into the upper sorting tube. The residual brown rice thus transferred to the upper sorting cylinder, the residual brown rice in the upper sorting cylinder, and the brown rice receiving gutter 17 in the upper sorting cylinder and for transporting the fallen rice. All the residual brown rice discharged from the gutter 19 is quickly discharged from the discharge side to the paddy supply hopper 10 in the hulling mechanism C as the upper sorting cylinder rotates.
