Steel cylinder rice polisher UltraPoly™

Overview The UltraPoly DRPG from Bühler is a high-throughput rice polisher designed to deliver elevated polishing performance while improving hygiene, energy efficiency and serviceability.

Key benefits

• Designed for easy cleanability: teeth are removable to leave a slot for cam access, facilitating cleaning and improving machine hygiene.
• Energy-efficient polishing: unique sieve design with reverse bends enhances polishing performance while reducing energy consumption.
• Highest-throughput capability: patented sieve, cam and teeth technologies enable polishing at throughputs up to 16 tons of rice per hour.

Highlight features

• Optional extra — Mixing tube: Optional stainless steel mixing tube to add pre-conditioner and reduce bran streaks; includes an integrated flow meter and control valves for precise water dosing.
• Innovative cam and teeth design: Cam teeth are mounted at a 45° angle on the cam periphery, allowing straightforward tooth-height adjustment to achieve the required polish and support higher head rice yield.
• Maintenance: Sieves are firmly locked to extend service life; the cam is split into six parts so only worn sections require replacement; individual teeth are replaceable to lower maintenance costs; feed screw is reversible to use both sides.

Applications Polishing of rice at high throughput where improved energy efficiency, hygiene and serviceability are required.
