Rototherm®
The Artisan Rototherm® is a horizontal,
mechanically-aided, thin-film processor
designed to handle a wide range of
evaporation and drying applications.
The bladed rotor creates a centrifugal force
that keeps the feed against the heated
process wall. The turbulent thin-film
between the rotor blade and the process
wall, covers the entire heated section at all
times, regardless of feed or evaporation
rates.
• Reduced degradation of heat sensitive materials
• Improved product quality
• Higher yields
• High viscosity capability (up to 4x106 cP)
• Up to 99% evaporation in a single pass
• High turndown ratio (10:1)
• No dry spots or fouling
• Smaller heat transfer area required
• Easier installation
• Easier to maintain
• Co-current or counter-current operation
• Less solvent required for cleaning
This film is constantly renewed, as the concentrated material is displaced towards the bottom
discharge nozzle, by the incoming feed. As the residence time is generally measured in seconds, the
degradation of heat sensitive materials is minimized.
As a reactor, multiple feed points, multiple temperature zones, controlled residence time and
simultaneous evaporation, offer total flexibility for processing continuous reactions - some powder
applications can also be processed in a single step.
