A driving device of sorting cylinders for use in a rotary type rice hulling and sorting device, characterized by comprising a hulling part, a pneumatical sorting part and a rotary type sorting part provided with sorting cylinders rotatably installed therein with one end thereof as the feeding side of rice grains to be sorted and the other end thereof as the discharging side of rice hulled and sorted and having a large number of recesses formed on the internal surface thereof and receiving troughs for taking out the rice grains scooped up by said recesses, said hulling part, said pneumatical sorting part and said rotary type sorting part being integrally constructed and interlocked, and the rotational speed of said sorting cylinders being controllable optionally in no connection with the revolution of said hulling part and said pneumatical sorting part.

Driving device of sorting cylinder for use in a rotary type rice hulling

A rice hulling and sorting machine includes a pair of hulling rolls which drop husked rice grains into a pneumatic sorting compartment which the husks are preliminary sorted from the rice grains; the rice grains thereafter being thrown upwardly into one end of the upper of two horizontally mounted rotating sorting cylinders. The interior surfaces of these cylinders have a multitude of recesses for trapping single rice grains at the bottom of their circumferential paths of movement to carry them upwardly and dropping them into conveying troughs which run the length of the interiors of the cylinders. Rice grains which are not trapped in the upper cylinder are fed back into the hulling rolls while those dropped into the upper trough are fed to the lower interior of the lower cylinder where they are again subject to being trapped in the recesses of the lower cylinder and dropped into the lower conveyor trough. Rice grains which are not trapped in the lower trough are fed back into the pneumatic sorting compartment while those dropped into the lower trough are discharged from the machine. An angularly adjustable plate extends along one side of each trough which controls the location in the circumferential path at which trapped rice grains fall into each trough.
