Key benefits

Modular design
The Rotosort comes in modules, allowing you to assemble your system exactly to the size and production capacity you require for your rice processing.
Speed adjustment
Adjust the revolutions of the screening drum to obtain the separation of rice and paddy you need. Simply adjust the gearmotor to the level you require.
Designed for low maintenance
The Rotosort's nylon gears are designed for a long life. A nylon brush cleans the entire length of the drum, keeping the sieve openings free. Maintenance requirements are kept low due to the slip-free and maintenance-free timing-belt drive.
