WIPED FILM EVAPORATION
Wiped film evaporator
Increase of turbulence
• increased heat transfer by turbulent film
• short residence time
• wiping of viscous and solidified films possible
• achievable pressure 1 mbar

SHORT PATH EVAPORATION
Short Path Evaporator
- short residence time due to turbulent film - very small pressure drop for vapors - achievable pressure 10 -3 mbar
but:
- limited viscosities, no solidifying products distillable
