Although the hulling and sorting work is carried out as described above,
The brown rice falls from the finishing rice drop port 30 to the finishing rice wind selection path 26 and is air-sorted, but it is dropped from the pressure wind karaki 27 located close to the starting end of the finishing rice wind selection path 26. As a result, the turbulent sorting wind flows into the starting end of the finishing rice wind sorting channel 26, but when it passes through the wind equalizing plate 31, it receives a wind regulating action and is evenly divided over the entire width of the wind channel. The brown rice flowing down from the finished rice falling path 30 on the terminal side of the air-leveling plate 31 can be sorted with a substantially uniform sorting air over the entire width, and the accuracy of the sorting air can be improved. In addition, the grains thrown up by the rotation of the finished rice discharge helix 29 are caught by the air leveling plate 31 and are prevented from being thrown away to the end side of the finished rice air selection path 26. Therefore, it is possible to prevent the sorting disorder in the finishing rice wind sorting path 26.
