Advantages:
Good heat exchange efficiency
Minimal thermal stress, thanks to low operating capacity
No dead zones, here for overheating prevented and a constantly high product quality guaranteed
Permanent mechanical cleaning of the heating surface prevents incrustations
Scope of application:
Concentration of highly viscous products, polluted liquids, salts solutions, oils, resins etc.
Sludge drainage
High-boiling liquids distillation in high vacuum conditions
Degassing, removal of volatile components (monomers) from highly viscous products, melts and pastes
Process principle:
Thin film evaporator consists of a tubular heat transfer area with an external heating jacket and fast-rotating, inner rotor with flexible or rigid wiper elements.
Under the influence of the rotor scrapers, the solution entering the evaporator is evenly distributed along the walls of the housing in the form of a thin film and flows down under the influence of gravity.
In this case, intensive evaporation of the solvent occurs, which is further intensified by turbulence of the liquid by moving rotor scrapers.
Depending on the application, different types of thin film evaporator have been developed for specific uses.
