WIPED FILM EVAPORATORS / SHORT PATH EVAPORATORS

Wiped Film Evaporator is designed to handle challenging evaporating requirements with materials that are heat-sensitive, highly viscous, or of low thermal conductivity. This technology involves separating volatile compounds by introducing a mechanical agitated thin film of feed material to a heated surface.

It is recommended for concentrating, separating, refining, decolorizing & deodorizing, & offers broad product development opportunities to the chemical, pharmaceutical, polymers and food industries. Typical products handled include fatty acids, fatty amines, tall oil, fruit juices, esters, plasticizers, rocket fuels, urea, etc.

MATERIAL OF CONSTRUCTION

Stainless steel, Boiler Quality/Carbon steel for product-contact surfaces. The Wipers will be of Graphite.

HOW IT OPERATES
Feed material enters through inlet , passes onto the distributor plate, then through four evenly spaced weirs onto the internal heated wall. Rotating slotted wipers spread the feed material into a uniform thin film and continuously move even highly viscous materials down the heated wall. Vaporized material passes through the entrainment separator and condenses on the internal U bundle condenser. Distillate flows out the distillate outlet and non-condensables flow out through the vapor outlet. The bottom, or residue, continues collector and flows out the residue outlet. Droplets of liquid caught by the entrainment separator flow down and off the separator into the residue collector. Extruder blades , mounted on the bottom of the rotor assembly, mechanically push the residue to the residue outlet.

BENEFITS

Short retention time eliminate product degradation. ▪ Low hold-up ▪ Floating wiper elements maintain thin film. ▪ Vacuum operation improves unit efficiency. ▪ Low maintenance, reduced downtime and optimal running costs. ▪ Energy saving features.
