PURPOSE: A dry milling process of rice flour is provided to provide rice flour powder which has less water absorbing powers due to the damages of the starch and increases in the cost of processing the product such as baked bread after kneading. CONSTITUTION: A rice flour milling method includes a centrifugal process after extra-high voltage processing, tempering, and atomizing water to rice. Tempering atomize rice into 30 weight% and seal for three hours at 40°；C. Roughened rice is performed with extra-high treatment in a super high-pressure device at 40°；C and 100MPa for 1 hour. Centrifugal grinding has a rotary plate gap for 0.3-1.5cm using a centrifugal force pulverizing device.
