The radial tarar is used in order to remove particles that are lighter then the grain by means of air. Using the fan that is mounted on the machine, the wheat and foreign materials are separated. The collected foreign materials are carried away by a screw conveyor and exit the system through the discharge spout. The machine is equipped with a pneumatic assembly that cleans the air inlet channels continuously. Since it contains its own fan and cyclone system, the radial tarar does not bring extra load to existing aspiration systems and the investment cost is lower.
