PROBLEM TO BE SOLVED: To make it possible to visually confirm an operation of a hulling roll with a simple constitution.;SOLUTION: In a hulling sorter, a hulling roll (8), a sorting part (3) which sorts rice hulled by the hulling roll and brown rice, an operation switch (35) and a hulling roll opening/closing switch (37), and an indicator (38) for displaying a gap position of the hulling rolls during hulling operation are plurally juxtaposed in a longitudinal direction. An opening switch and a closing switch of the roll opening/closing switch are provided on the left and the right of the indicator, and a main motor (39) for driving a hulling part (1) and a load current detection sensor (40) of the main motor are provided. The hulling sorter comprises a control part. When a load current value becomes equal to or more than a set value, the control part performs over load processing control for widening the hulling roll gap by a specified amount and time control for narrowing the hulling roll gap by a specified amount at every set time during hulling operation. When performing over load processing control, a first lighting output for lighting the indicators in order from a closed side toward an opening side is performed, and when performing time control, a second lighting output for lighting the indicators in order from the opening side to the closed side is performed.;SELECTED DRAWING: Figure 7;COPYRIGHT: (C)2018,JPO&INPIT
