In this state, when brown rice is supplied from the supply gutter 33, the brown rice is raised by the frying spiral 25 rotating in an optimal state,
The surface is initially ground and polished by the grinding rotary mill roll 27,
The brown rice whose surface is damaged is stored in the communication room 41 in the communication tube 34.

In this case, the degree of the initial grinding and polishing is adjusted by an adjustment handle 45 screwed into a vertical cylinder 44 provided on the upper lid 43. That is, when the adjustment handle 45 is rotated, the strength of the spring 49 between the flange 48 and the adjustment handle 45 is adjusted, so that the resistance of the resistance valve 42 is adjusted.
