To provide a method for producing rice flour preferable for applying as a raw material for rice flour bread and as a food material applicable to a small production apparatus in accord with local characteristics, to provide an apparatus for producing the rice flour, and to provide a method for producing rice flour for rice flour bread, making soaking constant and the apparatus minimized, suppressing increase of rice temperature due to powdering heat in a milling step and capable of finishing the powdered flour to have a constant moisture, and to provide an apparatus for producing the rice flour.

The method comprises continuously washing material rice with a rice washer 1, soaking the washed material rice in water with a continuous soaking conveyor 2, dripping water from the material rice, adjusting moisture of the material rice to about 28-34% with a tempering conveyor 3, finely milling the material rice with a vortex pulverizing mill 4, and drying the finely milled material rice with a flash dryer 5 to adjust moisture to be 12-14%.
