Claims (1)

[Scope of Claim for Utility Model Registration] A cylindrical sorting net and a grain frying helix having a main helical blade on the outer periphery of a helical shaft fitted inside the sorting net so that they rotate concentrically with each other. A cylindrical grain-receiving portion having a diameter substantially the same as the inner circumferential diameter of the sorting net is installed on a base so as to be located directly under the sorting net, and the grain-frying spiral body is placed vertically in the outer shell. The shaped grain receiving part and the sorting net are arranged so as to fit and rotate into the inside of the sorting net, and have an input port opened on the inner circumferential surface of the grain receiving part and an outlet of the input hopper provided outside the outer shell. In a vertical grain sorting machine connected by a chute, the helical pitch at the lowermost end of the main helical blade is set larger than the pitch in other areas, and the starting end of the main helical blade and the starting end of the main helical blade are set in the pitch enlarged part. is provided with auxiliary spiral blades whose starting ends are at different angular positions to form a locally multiple spiral structure, and a convex portion is provided on the upper surface of at least a portion of the main spiral blade that exists in the sorting area, and the input port is A vertical grain frying sorter characterized in that it is installed almost perpendicular to the rotation direction of a grain frying spiral, and the inner circumferential surface on the rotation direction side at the boundary between the grain receiver and the input port is chamfered.
