<p>PROBLEM TO BE SOLVED: To solve the problems that, in a rice milling device which conveys unhulled rice or hulled rice supplied to an input hopper by a spiral bucket (conveyance auger) of an input hopper bottom part, when negative pressure is high in a machine chamber housing a huller or the rice milling device, even if the spiral part of the spiral bucket of the input hopper bottom part is not rotated, supply rice in the input hopper is conveyed by suction negative pressure in the machine chamber, easily causing conveying clogging or a failure, and when the spiral rotation is temporarily stopped in the middle of a running operation, a small amount of supply rice remains in the spiral bucket, causing easy suction conveyance by the suction negative pressure.SOLUTION: In a coin rice milling machine, a suction port 12 for sucking and guiding outside air of a machine chamber 3 is disposed between an outlet 10 of a spiral bucket 5 and an inlet 11 of an elevator 6.</p> |
