Some melts remain liquid even when cooled below their melting point and are known as subcooling melts. The reason they refuse to crystallize and solidify is the lack of the crystal nuclei needed for these actions to take place.
However, a supercooling process has been developed to solidify these difficult subcooling melts by producing a homogeneous suspension of crystal nuclei in the melt. This process enables the melt to be crystallized on the steel belt in a very short time and can be used to produce the desired product form – such as pastilles, micropastilles or flakes.
Since developing this innovative system, we have designed, supplied and installed more than 50 supercooling plants. Each has been a turnkey system, incorporating everything from the precrystallizer to the Rotoformer, steel belt cooler and measurement and control equipment.
Pastillation directly from the melt for the following applications:
- Photo chemicals
- Plastic additives
- Rubber chemicals
