Abstract:
1. A grain processor for separating grains from accretions accreting to the grains or contaminants intermingled with the grains comprising: a conveyor having holes in a conveying course thereof, wherein the holes are smaller than the grains and are sized optimally for passing the accretions and the contaminants therethrough, and the grains are placed on an upper surface of the conveyor; air-suction means, wherein the air above the surface is sucked downward to a lower side of the conveying course through the holes by the air-suction means; and air-blowing means, wherein the air-blowing means blows air upward from the lower side of the conveying course to the upper side of the conveying course through the holes at a predetermined position in the conveying course so as to apply blowing-up force onto the conveyed grains reaching the predetermined position, wherein an opening of the air-blowing means for blowing air has the same width as the width of the conveying course.
