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 machine for hulled grain employs a single horizontally disposed rotating hollow cylindrical body having its interior surface covered with a multiplicity of recesses designed to scoop up individual hulled grains at the bottom and to drop them out near the top. A partition separates the body into two compartments and two troughs containing screw conveyors extend the length of the cylindrical body and an arrangement of longitudinally extending plates are combined with the partition so that in the first compartment one of the conveying troughs brings the grains from a huller to the far end of the compartment while the other conveying trough catches the dropped grains and carries them to the far end of the second compartment and discharges them at that point to the bottom of the cylindrical body for re-sorting while the first conveying trough in the second compartment catches the re-sorted grains as they drop from above and carries them on to be discharged at the far end of the cylindrical body.

Cylinder-type rotary sorting apparatus

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.
