The IPCO Rotoform granulation system combines a Rotoform drop depositor with a steel belt cooler. Molten product is fed to the Rotoform pastillator via a pump and then uniformly deposited – in the form of consistently sized, dust-free granules – across the full width of the steel belt.

The drops are solidified and cooled as they travel along with the belt. Water sprayed onto the underside of the belt removes the heat of the product and ensures cooling of the pastilles.

The solidified product is discharged at the end of the steel belt in the form of hard, uniform pastilles of an optimal shape. The pastilles are free-flowing and virtually dust-free, and are ready for storage or bagging.


Features and benefits

  • Direct solidification from the melt, eliminating the energy and equipment costs associated with subsequent crushing, breaking or grinding processes.
  • Pastilles of a highly uniform shape and stability for dust-free production.
  • Free flowing pastilles, ideal for handling, blending, storage and further processing
  • Higher bulk density and better packing properties than bulky flakes
  • Environmentally friendly production as cooling media as cooling media (water) and product are kept apart – no possibility of cross contamination
  • Fast cooling on the belt means very few vapor or gas can get into the atmosphere and minimizes oxygen contact of the hot product.
  • Melts with widely varying properties can be handled including viscosities from 10 to 40 000 mPas and temperatures up to 300 °C.
  • Pastilles can be produced with diameters from 0.8 – 36 mm.

Different types of Rotoform systems

The Rotoform technology has been developed over many years to meet the different process requirements of a wide range of products. Whatever challenge you need to overcome, whatever your production requirements are, we have the Rotoform system to match.
