The fourth valve n supplies brown rice to the grain sorting device path and removes waste rice by the grain sorting device path only when the lower limit switch 24 is turned on. The good brown rice from which the waste rice has been removed is stored in the good brown rice tank C via the flow path 41, through the good brown rice lift 43. , waste rice tank 6 via relay waste rice elevator I
is stored in

(Effects) Conventionally, a plant is known that is provided with a hulling section that hulls the unhulled rice supplied by a supply conveyor, and a swinging sorting device that swings and sorts the mixed rice hulled by the hulling section.

The known method has a problem in sorting because it uses - number of oscillating sorting devices.

There were also various problems with automation.

Therefore, the present invention includes a hulling section 5 that hulls the unhulled rice supplied by the supply conveyor 2, a first swinging sorting device 319 that swings and sorts the mixed rice hulled by the hulling section 5, and A second oscillating sorting device 4 for further oscillating sorting the brown rice sorted by the second oscillating sorting device 4, a grain sorting device path for finely sorting the brown rice sorted by the second oscillating sorting device 4, and a single grain sorting device. The hopper 6 of the hulling section 5 is equipped with an upper level switch 7.
and a lower level switch 8 are provided, and the upper level switch 7, the lower level switch 8, and the supply conveyor 2 are arranged so that when the lower level switch 8 is turned off, the supply conveyor 2 starts rotating and the upper level switch 7 is turned on. The supply conveyor 2 is connected so as to stop rotating when The rear of the sorting device is configured to supply brown rice to the grain sorting device 36 only when the lower limit switch 24 is turned on, and the upper limit switch δ and the second tank n are connected to the second tank n while the upper limit switch 3 is turned off. Since this is an automatic control device for a hulling device configured to return unhulled rice to two tanks (B), the supply conveyor 2 is rotated by the upper level switch 7 and lower level switch 8 provided in the hopper 6 of the hulling section 5. The plant can stop and supply unhulled rice smoothly, and since the second swinging sorting device 4 is installed outside the swinging sorting device 9 for sorting, there is less burden on the swinging sorting device 9, and therefore the flow is not unreasonable. The second oscillating sorting device has a very low unhulled rice content, so it is difficult to sort it, but an upper limit switch δ is installed in the second tank B of the second oscillating sorting device 4, and the upper limit When the switch δ is off, the unhulled rice is returned to the second tank n, which has the effect of smooth operation.
