Wiped film and thin film evaporators consist of a cylindrical heating jacket and an inner rotating wiper system, distributing the product on the heating jacket as a thin and turbulent film. The turbulence in the wiped film increases the heat and mass transfer to achieve a high evaporation rate at short residence times, often within a single processing pass. The separated vapors are either condensed on an external condenser or further separated in a fractional column. Wiped film and thin film evaporation allow the handling of heat-sensitive, fouling and viscous products.

Testing at VTA test center?
VTA delivers package units in laboratory, pilot and industrial scale. Package units are skid mounted, pre-assembled systems for wiped film
and short path distillation, rectification and thin film drying.
All core components, like evaporators, condensers, vessels and piping, are manufactured in modern manufacturing facilities by highly qualified
workers either by VTA or within the STREICHER group.
All engineering services are performed entirely inhouse at VTA. By minimizing the interfaces, a smooth project execution is ensured.
