Milling characteristics of cutting type rice milling machine (I) – Characteristics of milling in accordance with blowing velocity

Abstract This study was to identify proper blowing velocity conditions to remove rice bran during milling. The milling characteristics were measured at four levels of blowing velocity 20, 25, 30, 35 m/s. The rise of grain temperature of milled rice was the lowest, 16.9 °C at 35 m/s. The differences of cracked ratio and broken rice occurrence ratio between before and after milling were found to be slightly lower at 35 m/s than other blowing velocities. Turbidity was decreased at high blowing velocity, and showed the lowest value at 35 m/s.
