Falling Film Evaporators: The Ultimate Guide

Nov 20, 2019 · There are also wiped film evaporators which use wiper blades to "smear" the liquid solvent into a thin film onto the walls of a heated tube. This can increase or decrease the residence time in order to speed up or slow down the rate of evaporation. Additionally, there are also climbing film evaporators or climbing film plate evaporators.

Types of Evaporators — Vobis, LLC

These wiped film evaporators are typically called molecular stills or short path evaporators. Advantages: These devices can process extremely viscous (to several million cP), heat-sensitive or crystallizing liquids, as well as slurries.

Evaporation (deposition) - Wikipedia

Evaporation is a common method of thin-film deposition. The source material is evaporated in a vacuum. The vacuum allows vapor particles to travel directly to the target object (substrate), where they condense back to a solid state. Evaporation is used in microfabrication, and to make macro-scale products such as metallized plastic film.
