IPCO’s patented Rotoform solidification process produces consistently sized pastilles directly from the melt to help you maximize competitiveness through improved quality and productivity.

Rotoform granulation for consistent, free-flowing pastilles

The Rotoform pastillation system combines proven Rotoform drop depositor technology with a steel belt cooling line. The result is an environmentally friendly solidification system capable of producing granules of highly uniform shape, stability, and quality.

The IPCO Rotoform was introduced in 1980 and is the original pastillation process. Since then, we have continued to innovate and now have a complete family of systems, with adaptations for almost every type of product.

Whatever you need to solidify, we can help you maximize productivity.

How it works

The IPCO Rotoform principle – proven in over 2500+ installations

The Rotoform drop depositor comprises:

a heated cylindrical stator that is supplied with liquid product
a perforated rotating shell that turns concentrically around the stator

Drops of the product are deposited by the nozzle bar across the whole operating width of a continuously running stainless steel belt cooler.

How it works

Clean, uniform pastillation

An innovative system provides uniform pressure and an even flow across the whole belt width. The speed of the Rotoform is synchronized with the speed of the belt to deposit the liquid droplets cleanly. This ensures the pastilles are precise and uniform.

How it works

Precise and efficient cooling

Heat released during cooling and solidification is transferred via the steel belt to cooling water sprayed underneath. This water is collected in tanks and returned to the re-cooling system. No water comes into contact with the product.

Benefits

Rotoform processing for quality, versatility, and reproducibility

Easy storage, handling, packing, and reprocessing: high-density, free-flowing pastilles with diameters from 0.8–36 mm
Versatile: handles melts with viscosities of 10–40,000 mPas and temperatures up to 300 °C
No need for crushing, breaking or grinding: solidification direct from the melt
Precise processing, with no cross-contamination: no contact between product and cooling water, and dust-free, environmentally friendly production
Minimal vapor/gas escapes: and minimal oxygen contact with the hot product thanks to fast cooling
