度籾摺作用を受けるようになる。 Since the structure of this embodiment is as described above, the working state of the rice huller A is that when paddy is supplied to the hopper 11 from the rice bag, it is removed by the huller C, and the rice that has been removed is removed. It is wind sorted as it falls into the wind sorting device B, and the rice husks and second grains are removed, and the mixed rice of brown rice and paddy falls onto the sliding rice screw conveyor 1 and is bounced by the sliding rice thrower 7. The rice is lifted up and supplied to the right side in FIG. 1, that is, the starting end side, in the upper rotary sorting tube a from the rice receiving trough 16. This rotary sorting tube a is rotating in the direction of arrow (A), and the supplied mixed rice is about to be drawn up into the depression 13, but the brown rice sinks and gets stuck in the depression 13, and compared to paddy. It is pumped upwards and falls in a large parabola. At that time, what is pumped upwards and released is brown rice without paddy mixed in, waste rice, and small grains such as unhulled rice, which fall into the brown rice receiving trough 14. Next, what is pumped up to the middle and released is brown rice with some paddy mixed in, and this falls into the receiving gutter 15 for reelection. Since the paddy cannot be pumped up to that extent, a portion of the paddy flows from the opening 24 into the sluice rice receiving trough 16 together with the brown rice, and is lifted up by the sludge rice thrower 7 and joins the supplied mixed rice. In this way, the rice is separated into a mixture of small grains and brown rice, brown rice with some paddy mixed in, and paddy mixed with some brown rice. And which of these receiving gutter 14, 1
Paddy that cannot be pumped either in 5 or 16 is transferred to the rotating sorting tube a.
It flows out from the terminal end and is returned to the hopper 11 where it is subjected to the hulling action again.

取出される。 The mixture of small grains and brown rice pumped up into the brown rice receiving trough 14 is carried out to the finished brown rice receiving trough 17 housed in the lower rotary sorting cylinder b via the carry-out route 18, and during its carrying out. Linear rice selection device 1
9 to select and remove small particles. In particular, small grains (waste rice, broken rice) are easily pumped up in the upper rotary sorting cylinder a, and because the grains are small, the parabola draws larger from a higher position, making it easier for them to enter the receiving trough 14 located on the most downstream side. . On the other hand, since the amount of brown rice pumped into the receiving trough 14 is small in total and contains many small grains, even the linear rice sorting device 19 with low sorting performance is effective in sorting and removing the small grains. The selected small particles are taken out from the small particle outlet 25.

落下し新たな混合物に合流するのである。 In addition, the brown rice mixed with some paddy that has been pumped into the re-selection receiving trough 15 is supplied by the shutter 20 to the inlet side of the rotary sorting tube b in the lower stage, and is shown by the arrow (b) of the rotary sorting tube b. Indentation 1 due to rotation of direction
Under the pumping action of step 3, the brown rice falls into the finished brown rice receiving trough 17, and from its terminal end it passes through the wind sorting device B.
While falling, the brown rice is screened to remove fine dust, and is transported from the brown rice screw conveyor 2 to the outside of the machine by the brown rice thrower 8. Then, the paddy and some brown rice that cannot be pumped up into the receiving trough 17 fall into the rice-grilling sorting chamber 3 and join the new mixture.

果を奏するのである。 In summary, the present invention has a rotary sorting tube with a large number of depressions formed on its inner circumferential surface, which is horizontally suspended, and a plurality of receiving troughs inside the rotary sorting tube to receive the materials drawn up by the depressions. A rice sorting device is interposed in the carrying out route, and a carrying out route is connected to the terminal end of the receiving ditch which is located on the most downstream side in the rotational direction of the rotary sorting cylinder among the receiving ditches. Since it is characterized by the following characteristics, it produces the effects described below.
