APPARATUS FOR DECREASING RESIDUAL GRAINS IN DISC SORTER

PURPOSE: To decrease residual grains by erecting resistors between the sorting disks at the point where flow is turned and a fluidized bed is formed by turning of the sorting disks. CONSTITUTION: The paddy in a paddy tank 1 is supplied to hulling rolls 2 and is hulled. The hulled matter is winnowed in a sorting wind path 6, by which chaff and abortive grains are removed. The removed mixed rice of unpolished rice and paddy flows into a mixed rice transporting trough 4 and is lifted by a mixed rice thrower 7, from the top end of which the mixed rice is thrown into a receiving box 17 and is supplied from a dropping port 16 to the supply side of the disk type sorter C. The mixed rice supplied thereto receives the lifting action by pot holes 20 while the fluidized bed P is formed by turning in a direction (a) of the sorting disks 11. The unpolished rice falls into an unpolished rice trough 12 and while the unpolished rice drops into an unpolished rice take-out trough 14, the unpolished rice is subjected to finish winnowing in a winnowing path 15 and is taken to the outside of the machine from the unpolished rice take-out trough 14.
