(effect) Next, we will discuss the effect.

When unhulled rice is supplied to the supply hopper 2 of the hulling section l, the amount of unloaded rice is adjusted by the loading control valve 3, and the unhulled rice is supplied to the hulling roll 5.5 by the loading roll 4, where it is hulled and wind sorted. The rice husks fall into the chamber 7 and are discharged from the exhaust pipe by the selection air from the suction blower 8 and the blower blower 9, and the immature rice falls into the immature rice receiving trough 13 and is taken out from the immature rice conveyor 11. The mixed rice falls into the mixed rice receiving trough 12, is taken out by the mixed rice conveyor 10, is fried in the hopper 29 by the thrower 16, and from the hopper 29 is transferred to the horizontal shaft rotating cylinder 2 of the dissimilar grain sorting section 18.
Supplied within 0. Since the horizontal rotating cylinder 20 is rotating, the grains are stacked in a flowing layer and are shifted toward the rotating side.The brown rice that has settled to the lower layer is scooped up by the pot hole 19 and taken out to the water receiving gutter 21, where it is used as finished rice. The rice is transferred to the discharge side by the spiral 22, falls into the finished rice take-out gutter 25-H, is transported horizontally by the finished rice conveyor 26, and is taken out of the machine. The unhulled rice remaining in the horizontal shaft rotating cylinder 20 moves in the same manner, and then falls from the discharge side of the horizontal shaft rotating cylinder 20 into the unhulled rice receiving trough 27-1-, is taken out by the unhulled rice recovery conveyor 28, and is sent to the supply hopper 2 by a nuller. returned and reprocessed.

Therefore, a large amount of the unhusked grains that are air sorted in the wind sorting chamber 7 and fall onto the mixed rice receiving trough 12 fall from the left and right center of the receiving trough 12. However.

Since a sample collection tube 15 is provided in the left and right center of the receiving trough 12 near the suction blower 8, a portion of the hulled material that falls in large quantities from the center falls into the collection tube 15 and is not removed. A rate sensor 17 measures the demolition rate.

In this measurement, the average demolition rate is determined by averaging the measured values several times, and the roll gap adjustment device 6 is controlled based on this average demolition rate. Since the rice husk dust is removed by the wind sorting chamber 7, it does not fall into the collection tube 15, and since the sensor 17 is installed in the collection tube 15, there is no influence of the sorting wind at the measurement position, allowing accurate removal. Possible to measure cell rate.

Therefore, in another embodiment, samples of the rice grains falling into the receiving trough 12 are equally sampled from the center, left side, and right side of the receiving trough 12, the dehulling rate of each is measured, and the average Since the roll gap adjustment device 6 is controlled based on the value, it is possible to measure a value closer to the average dehulling rate of all hulled products.
A rice huller having a rice huller l provided with a rice huller, a wind-selection chamber 7 for wind-selecting the hulled material produced by the rice huller l, and a mixed rice receiving trough 12 for taking out the selected mixed rice from which rice husk dust and the like have been removed. In the apparatus, a sample collection pipe 15 is connected to the receiving trough 12, and a demolition rate sensor 17 is provided in the sample collection pipe 15.
7 and the automatic gap adjustment device 6 are connected to each other, and the plurality of sample collection tubes 15 are each provided with a dehulling rate sensor 17.
This is because the automatic gap adjustment device for the hulling rolls in the hulling device is provided in the mixed rice receiving trough 12 at equal intervals in the left and right directions.

a. The sensor 17 detects a portion of the mixed rice flowing on the mixed rice receiving trough 12 to measure the dehulling rate, and the roll gap is adjusted based on this, so the adjustment is accurate.

b. Because the sample collection tube 15 was attached to the mixed rice receiving gutter 12,
Dust, rice husks, etc. do not get mixed into the sample collection tube 15.

Since the C0 sample collection tubes 15 are provided at the left, right and center of the mixed rice receiving trough 12, the detection accuracy of the dehulling rate is further improved.

d. Most of the mixed rice passing through the mixed rice receiving trough 12 is in the central part of the receiving trough 12, and samples in the vicinity are collected several times, so reliability is high.
