Large capacity wiped film distillation system
Thin film evaporation are mostly used for first-stage degassing to prevent explosive boiling when entering the main evaporator, especially for the high light component ratio conditions. The HXCHEM thin Film Evaporators normally operate within a pressure range of 1 mbar to 100 mbar.

Details
Single Stage Thin Film Distillation System For Degassing
Introduction
Single-stage thin film distillation is mostly used for solvent recycling, but in multi-stage distillation, thin film evaporators are mostly used for first-stage degassing to prevent explosive boiling when entering the main evaporator, especially for the high light component ratio conditions. In a thin film evaporator(TFE), a rotating wiper system distributes the crude product to a film on the inner surface of a heated surface. The wiping system speeds up the evaporation process by keeping the product film turbulent so that the heat transfer and mass transfer are optimized. The vapour are condensed on the external condenser and the residue are discharged from the bottom of the evaporator.
