"Problems to be solved by the invention" In the above-mentioned conventional technology, the grain is put into the lower end of the sorting cylinder, the inside of the sorting cylinder is lifted up by an auger, and the waste rice is leaked to the outer periphery on the way, Since the unpolished rice was taken out from the upper end side, the grains being lifted by the auger were milled in the sorting tube, and it was easy to generate lumps in the sorting tube, and the sorting tube clogged with lumps and the unpolished rice was scraped. There is a problem that the rice becomes skin-misaligned, and there is a problem that it is not possible to easily improve the sorting accuracy and prevent damage to the smoothed brown rice.

[Means for Solving the Problem] However, in the present invention, a plurality of sorting cylinders are arranged on the same circumference centered on a spindle that stands substantially vertically, and each sorting cylinder revolves around the spindle. In the grain sorting device that rotates the sorting cylinder about the axis of the axis, the upper hopper outlet is communicated with the opening in the center of the upper end of each sorting cylinder, while the waste rice leaked from the middle of the upper and lower width of the sorting cylinder to the outer periphery is received. A scraped rice gutter and a straightened rice gutter that receives the straightened rice falling from the lower end opening of the sorting cylinder are provided at the lower end of the sorting cylinder, and the straightened rice gutter is attached to a lower position than the scrap rice gutter, and the spindle is also attached. It is characterized in that a circular scrap rice gutter inner diameter is formed larger than a circular shaped unpolished rice gutter inner diameter.

[Operation] Therefore, the grains to be sorted in the hopper can be put into the axis of the sorting cylinder through the opening in the center of the upper end of the sorting cylinder, and the grains to be sorted can be dispersed substantially evenly in the inner circumferential direction of the sorting cylinder to improve the sorting accuracy. Not only can it be improved, but a scrap rice gutter is provided on the outside above the plain rice gutter,
