The Wiped Film Evaporator (WFE) is used for concentration, distilling,
stripping, dehydration and deodorisation of products which are heat sensitive or
viscous. The equipment can handle a very wide range of feed compositions ranging from 1%
to over 95% concentration. WFE has several advantages as stated in the table below. The
operation is continuous with a single pass; the self cleaning continuous contact wipers
produce and renew the thin film. Such an operation improves product yield, avoids
residue and colour formation. It has an internal condenser (optional) that minimizes the
pressure drop and maintains vacuum.
