Five Roll chocolate refiner

When you want to produce high quality traditional chocolate, a 5 Roll Refiner gives you complete control of your product quality. For frequent recipe changes, individual roll drives and advanced automation will help you master your process.

Fully automated 5 Roll refining

The 5-Roll Refiner from Royal Duyvis Wiener is the most hygienic 5 roll refiner available. With its fully automated functions, controlled by the PLC buffer, the five-roll refiner maximizes your production up to four batches /hour. Versatility of your production line is ensured, by adjusting the roll’s revolution speed and friction ratio.

Particle size management is the answer when undesired product fluctuations jeopardize your production. Installed on top of the 5th roll, the particle size management device directly measures the particle size at two locations on the roll (center and side), without using an indirect layer thickness. Every 20 ms, the cocoa, chocolate and white mass are measured automatically and at the same time the settings of the 5-roll refiner are controlled.
