AI Technical Summary
Existing rice polishing machines have difficulty effectively separating bran powder from rice during the polishing process, and are not easy to wet, which increases the possibility of rice grain breakage and reduces polishing quality.
A polishing machine comprising a polishing mechanism, a spraying mechanism, and a screening mechanism is designed. Rice is conveyed to the polishing screen by a conveying component, polished by polishing rollers and polishing strips, while the spraying mechanism moistens the rice. The polishing screen separates rice bran from rice, and the screening mechanism collects broken rice and rice bran.
It effectively reduced the breakage rate during rice polishing, improved polishing quality, and achieved effective separation of bran powder and rice, meeting usage requirements.
