High evaporation rates within a single process path
Wiped Film and Thin Film evaporation enable the processing of heat-sensitive, fouling, and viscous products.
Wiped Film and Thin Film Evaporators comprise a cylindrical heating jacket and an inner rotating wiper system, dispersing the product onto the heating jacket as a thin and turbulent film. The turbulence within the wiped film enhances heat and mass transfer, achieving a high evaporation rate with 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.
