The Royal Duyvis Wiener 5-roll refiners are designed according the latest global standards. Advanced technology and new design details result in a roll refiner of unmatched performance.
The product is transported from pre-refiner (2-roll-refiner) by a conveyor belt in the buffer located at the top of the 5-roll pre-refiner. This buffer acts as a storage centre for a continuous feeding onto the rollers of the fine-refiner. The state-of-the-art rolls work to refine and calibrate all particles in the chocolate batch. The 5-roll refiner is extremely durable, resistant to wear and is executed with specially designed hydraulic controls, gap adjustment and drive technology.
This results in consistently produced fine-refined chocolate batches, ready for the next step – conching.
Particle fineness up to 12 microns is achievable, ensuring maximum product quality. The advanced control unit as well as several safety devices guarantee reliable and traceable production and avoid run dry damage by feeding foreign materials. High quality centrifugal cast composite rolls with an even, hard surface ensure high product quality and an extremely long lifespan.
The 5-roll refiners are suitable for use as a fine-refiner in chocolate processing lines. The equipment guarantees the highest product quality, flexible handling and a long life span. The two temperature controlled rolls pre-refine the sugar and the calibration of the particle size is determined by the gap between the roll and the pressure which is hydraulically controlled. The rolls are standard driven via two geared motors, optional each individual roll can be executed with a separate drive. For greater accuracy, a frequency controller can be installed. The rolls can easily be dismantled and changed. The scraping knives can easily be cleaned and changed, which means a considerable cost saving (less downtime) and improved hygiene.
