White Falling Film Evaporator Distributor / High Speed Rotary Vacuum Film Evaporator

4000 - 12000 ml / h Feed Amount Wiped Film Evaporator for CBD / THC / Hemp oil

—— Design

Wiped Film Evaporators  are horizontal evaporator with wiper basket, gear motors and external condenser.
The vapour nozzle is typically arranged at the upper end of the evaporator in order to facilitate the transfer of the vapours to the external condenser.
Dea offers thin film evaporators from 0.058 to 3 m2 .

—— Particular features

Continuous distillation process.
Low operating pressures (100~10000Pa ,100Pa=1mbar).
Short residence time.
High evaporation rates.
Processing of high-boiling, high-viscosity or crystallizing products is possible.
Can be used as a reboiler for column.
Low fouling on evaporator wall.

Wiped film evaporators (WFEs) are often used in the petrochemical, chemical and food industries to remove a volatile component from a very nonvolatile mixture. Wiped film evaporators provide a short residence time and are often operated under vacuum for temperature sensitive mixtures. The wiped film evaporator utilizes a set of wiper blades or rollers to spread and thin the liquid along the surface of the heated wall. The wipers or rollers also induced convection within the liquid film which promotes evaporation of the volatile compound and enhances mass transfer within the film.
