Abstract

PURPOSE:To make easy improvement, etc., of sorting performance and efficiency and to more easily improve a husking sorting function than heretofore by constituting the husking sorting device in such a manner that the unpolished rice rate or supply rate of return unhulled rice, or hulling rate, etc., are judged in accordance with the output differences of a lower inlet sensor, intermediate sensor and outlet sensor. CONSTITUTION:The start of a husking operation is detected by the input of the shutter sensor, the input of the hulled rice quantity sensor 73 and the input of the photoconductive sensor 74. Automatic control is started by manual setting of the hulling rate. The hulling rate is then computed by the hulling rate sensor input and a hulling rate motor 7 is controlled to maintain approximately the same hulling rate of hulling rolls 3, 4. On the other hand, a supply motor 66 is controlled by the input of the supply sensor 63. The quantity of the unhulled rice supplied from the hulling rolls 3, 4 to a sorting cylinder 22 is adjusted and a sluice motor and sorting motor 24 are controlled by the inputs of the respective upper, middle and lower inlet sensors 56, 57, 58. The opening degree of the sluice plate and the number of revolutions of the sorting cylinder 22 are changed to an adequate state and the husking sorting operation is automatically performed.
