Then, when the moisture value of the rice, the brown rice, or both the rice and the brown rice reaches a preset moisture value, the dryer stop 18 is performed. These measurements are repeatedly performed until the measured moisture value reaches the set moisture value.

When the automatic operation 14 is NO and the sample inside the dryer is hulled to make brown rice and then discharged to the outside, the discharge shutter 9 is opened and the discharge shutter 9 is opened when the discharge 20 is YES and the discharge 20 is YES. 8 is brought down to the exit side to make it communicate with the outlet shutter 9 to the state shown in FIG. 4 (a), and the rice is hulled by the hulling rolls 4 and 5, and the brown rice is discharged to the outside via the shutter 8 and the outlet shutter 9 for switching the outlet. I do. If the brown rice is used and the discharge 20 is NO, the movable hulling roll 5 is raised to the state shown in FIG. 4B, and the sample inside the dryer is discharged to the outside without being hulled.

If the automatic operation 14 and the external discharge 19 are NO and the external sample supply 22 is YES,
3 is YES, the moisture measurement 6 is YES and the state shown in FIG. 6A is obtained. The external sample is hulled by the hulling rolls 4, 5 to make brown rice, and then the moisture is measured by the moisture meter electrode rolls 6, 6. In addition, when moisture is measured without hulling the external sample, the movable hulling roll 5 is raised to the state shown in FIG. Measure the water content according to 6. When the moisture measurement 6 is NO and the external sample is hulled to make brown rice and then discharged outside, the state shown in FIG. 5 is set, and the external sample is hulled by the hulling rolls 4 and 5, and the brown rice is subjected to the exit switching shutter 8, It is discharged to the outside through the discharge shutter 9.
