Key benefits

Our highest-throughput polisher

The UltraPoly features multiple patents and proprietary technologies, including innovative designs for the sieve, cam and teeth. They can deliver a high level of polishing even at high throughputs of up to 16 tons of rice per hour.

Pioneering and energy-efficient rice processing

Our unique design of the sieves with reverse bends helps improve polishing performance and save energy.

Designed for easy cleanability

Bran can accumulate in the shaft during polishing. We have therefore designed the UltraPoly for easy cleaning. You can remove the teeth, leaving a slot where you can access the cam for cleaning, which helps improve the standard of hygiene in the machine.

Highlight features

Optional extra

Improve the quality of your polishing with a mixing tube

You can add an optional mixing tube. You can use this to add pre-conditioner to decrease bran streaks and improve the polishing performance. The mixing tube comes with a flow meter and control valves, allowing you to precisely control the amount of water you need. It is also made from stainless steel to help increase hygiene during processing.

Innovative cam and teeth design

Adjust the cam teeth to the polish you need

The cam teeth are fitted at an angle of 45° on the cam periphery. This allows you to easily adjust the height of the teeth to the polish you need, helping increase your yield of head rice.


Designed to keep maintenance costs down

The sieves are firmly locked in place to improve sieve life. The cam is split into six parts, so you only need to replace the worn parts, not the whole cam. You can also replace individual teeth, helping reduce maintenance costs. The feed screw is also reversible, allowing you to use both sides.
