Passive pulley by motor of grain mill X and grain mill Y
By rotating 14, the vertical rotation main shaft 10 is rotated, and the friction rotary milling roll 15 and the downward feed milling roll 16 are rotated at a rotation speed suitable for the friction rotation. Further, the passive pulley 26 is rotated by the motor, and the hoisting spiral 25 and the grinding rotary milling roll 27 are rotated at a rotation speed suitable for the grinding rotation.

More suction, and a suction cylinder inside the bran discharge chamber 35
Suction from 36.

In this state, when brown rice is supplied to the supply gutter 33 of the grain milling apparatus X, the brown rice is raised by the milling spiral 25 that rotates in an optimal state, and the surface is primarily 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 primary grinding and polishing is adjusted by an adjusting 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.

The brown rice that has undergone the primary grinding and milling flows into the cap 23 and is lowered by the lower feeder roll 16. The lowering by the downward feeding and feeding roll 16 is also performed in a suitable state, is subjected to secondary friction polishing by the friction milling rotary roll 15, and is sent out from the sending roll 17 to the white rice discharge port 18 to be taken out. The degree of secondary friction polishing is adjusted by the resistance valve 51.

The rice grains subjected to the second friction milling are supplied to the supply gutter 33 of the grain milling device Y by the elevator for communication 53, rise by the milling spiral 25 rotating in an optimal state, and have a surface of 3 by the grinding rotary mill roll 27. The brown rice that has been ground and polished and the surface of which has been scratched again is stored in the communication room 41 in the communication tube 34.

In this case, the degree of tertiary grinding and polishing is adjusted by an adjusting handle 45 screwed into a vertical cylinder 44 provided on the upper lid 43.

The brown rice that has undergone the tertiary grinding and milling flows into the cap 23 and is lowered by the lower feeder roll 16. The lowering by the lower feeding and feeding roll 16 is also performed in a suitable state, and is subjected to the fourth friction polishing by the friction milling rotary roll 15, and is sent out from the sending roll 17 to the white rice discharge port 18 to be taken out.

Also, when the switching valve 54 is switched, the tertiary grinding and polishing are not performed.
Next, we grind the rub.
