Mass production of cosmetic products requires industrial quantities of base materials, and easy transport, storage, handling and dosability of these ingredients is essential.

IPCO’s Rotoform system, first used for chemical solidification more than 40 years ago, is capable of solidifying low and high viscous melts (up to 40 000 mPas) at temperatures up to 300 °C. A range of systems enables processing of everything from micropastiiles and small batches of between 10-20 kg/hr (important where small quantities of expensive materials are used), to high capacity requirements of 3000 kg/hr. IPCO can also supply end-to-end solidification solutions in full compliance with GMP guidelines.

The product is delivered to the system in melt form. The Rotoform consists of a heated cylindrical stator and a perforated rotating shell that turns concentrically around the stator. Drops of the product are deposited across the width of a continuously running stainless steel cooling belt.

The rotational speed of the Rotoform is synchronized with the belt to allow gentle deposition of the liquid droplets onto the belt without deformation. Heat released during cooling and solidification is transferred via the steel belt to cooling water sprayed underneath.

The Rotoform process converts the melt into solid beads of a defined and consistent size, a form that is free flowing and ideal for handling, storage, dosing and blending. And their uniform shape, stability and quality can be reproduced precisely, again and again.

While the Rotoform process is inherently clean and hygienic, a GMP-compliant process requires additional properties and features.

These include all-stainless steel framework and piping and the use of food grade lubricants. Other features can include special materials for seals and gaskets, a Rotoform drive with belt instead of chain, and an enclosed belt washing box with hot water or steam spraying nozzles and subsequent jet air for drying.
