The rotor is supported in the rotor case such that it can be rotatably driven about a horizontal shaft. Each of the blades has a blade end, and each blade end as viewed in elevation has a V-shape which is open to a front side in a predetermined rotation direction of each blade. A member is disposed above the inlet port having a shielding part and two inclining walls which have respective scratcxh-off edges, the two inclining walls opening into a V-shape toward a rear side in the predetermined rotation direction of each the blade, and the shielding part having a V-shape including a rear trip end. The rear tip end of the shielding part protrudes between the two inclining walls toward the rear side from a front central part of the two inclining walls. A bottom surface of the shielding part has a concave portion having a depth through which plural granules can pass. A plurality of air-vent grooves extend in a bottom surface of the member below respective ones of the inclining walls, each of which extend from a front side to a rear side of the member as viewed in the rotation direction.
