SMS offers its customers a unique range of high viscosity processors and the associated application technology. The program provides tailor-made solutions for process steps with viscous and difficult to treat products. The processors operate over a wide range of viscosities and residence times.

In addition to the longstanding and well-known thin-film processors Filmtruder and Viscon, SMS has developed single- and twin-shaft horizontal, large-volume processors of the types Reactotherm, Reasil and Reacom.

Design criteria that determine which technology is used include:

  • Residence time
  • Viscosity
  • Pressure
  • Temperature
  • Vapor volume
  • Mixing requirement
  • Melt vs. friable solids
  • Capital and operational cost
