However, according to the present invention, the wind tunnel 2 having the wind turbine 3 provided in the fixed case 1 for blowing the wind upward, and the swing frame 12 provided at the upper portion of the wind tunnel 2,
A sorting net 18 stretched over the swing frame 12 through which the wind blows upward, and an elevator 3 for supplying scrap rice onto the sorting net 18.
And a swinging mechanism for reciprocally swinging the sorting net 18 in a slanted vertical direction. The sorting net 18 has one side in the front-rear direction and one side in the left-right direction on the other side. The side is rocking upper side 21 and the other side is rocking side 22 into a substantially rectangular shape,
The supply side 19 is higher than the discharge side 20 and the swaying side 21 is higher than the swaying side 22 and is tilted in both directions, and the upper net 2 is formed on a punched perforated plate 25 in which numerous directional air holes 24 are formed.
Since it is a sorting device for extracting brown rice from double-structured waste rice obtained by polymerizing 3, the wind of the windmill 3 is blown through the air holes 24 of the punched perforated plate 25 and the eyes of the upper net 23. As it goes up, it becomes a soft wind and acts slightly on the light scrap rice and blows up to a position that is neither high nor low, so that the scrap rice can be smoothly drifted to the swaying side 22, which is not obtained in the known example. The separation effect that cannot be exhibited. Further, in the above apparatus, since the upper net 3 is a sorting device for taking out the brown rice from the scrap rice formed by the fine wire woven mesh, the brown rice is moved to the upper side 21 by the frictional resistance of the uneven surface peculiar to the woven mesh. It can be swung smoothly.
