Overview
The Rotosort™ drum grader DRGA grades rice, paddy and other granular products into two fractions. Designed for low maintenance, the machine features changeable sieves and an adjustable drum speed to optimise separation for rice processing lines.

Key benefits

• Low-maintenance components: nylon gears for extended service life, a full‑length nylon cleaning brush that keeps sieve openings clear, and a slip‑free timing‑belt drive that reduces upkeep.
• Adjustable separation: configure the gearmotor to change drum revolutions and obtain the required separation between rice and paddy.
• Modular scalability: available as modules so you can assemble a system sized to your production capacity.

Highlight features

• Quick screen changes: shaftless drive and interchangeable screens with large openings enable fast, easy screen swaps.
• Continuous cleaning: the rotating nylon brush cleans the drum during operation to minimise product residues and support food‑safety standards.
• Flexible applications: suitable for rice and paddy and also effective for cereal grains, oilseeds, nuts, coffee and cocoa beans.
