These machines are generally used for separating white rice by length into several different sizes.
The preliminary grading process is done by screen machines which effectively separates the fine broken and brewers from rice.
The material is fed into the machine through a conveyor into the centre of rotating cylinder.
The grains of shorter size are lodge in the indents and are lifted by the cylinder until they fall out under gravitational force into the internal trough.
The large particles remain in the trough for further separation.
Due to rotating speed and inclination of cylinder, the long grains are separated and are discharged out while the small grains and other crop seeds are discharged out separately with the help of augur or vibrating device fitted with trough.
Power: 2 HP
Operation:
The material enters the machine through the feeding device directly into the centre of the rotating cylinder.
The shorter than required size particles lodge in the indents and are lifted by the cylinder until they fall out under gravitational force into the internal trough.
Large particles not deposited in the indents are retained on the inside surface of the cylinder.
Due to rotating speed and inclination of cylinder, long grains are discharged out and rejects comprising of cut grains, small round grains and other crop seeds etc. are discharged out separately via auger or vibrating device fitted with trough.
