Thin film evaporators

One of the most modern and universal technologies, suitable for various processes of heat treatment of materials - evaporation, crystallization, drying.

Advantages:

  1. Good heat exchange efficiency

  2. Minimal thermal stress, thanks to low operating capacity

  3. No dead zones, here for overheating prevented and a constantly high product quality guaranteed

  4. 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.
