IPC: B02B3/06
Filed: 2011-08-29
Abstract: PROBLEM TO BE SOLVED: To efficiently convey bran powder in a bran removal chamber even under a small volume of air flow.SOLUTION: In a rice polishing machine 10, air in a case 22 is sucked through in an suction cylinder 42 to suck air in the case 22 through an air suction cylinder 40, and air flow is generated from a rice polishing chamber 32 to the suction cylinder 42 side through a bran removal hole 26 and a bran removal chamber 54.
