PROBLEM TO BE SOLVED: To provide an oscillation screening plate type hulling sorter in which a hulling operation can be carried out from start to finish by a single switch operation.SOLUTION: A controller (55) of a hulling sorter is provided, while a mixed rice upper limit sensor (SE3) detecting that the mixed rice is accumulated in a mixed rice tank (24) more than the set amount is installed and when a single operation start switch (SW1) is operated while respective units of the hulling sorter are being energized, which performs the steps of: turning on a main motor (M1) to start driving the respective units of the hulling sorter, as first actuation; activating an unhulled rice shutter control motor (M4) to open an unhulled rice shutter valve (31), as second actuation; and activating, when the mixed rice upper limit sensor (SE3) detects that the mixed rice is accumulated in the mixed rice tank (24) more than the set amount, a circulation/discharge switching valve control motor (M2) to switch the circulation/discharge switching valve (36) from a circulation state to a discharge state, as third actuation. |
