WFE

Description

A wiped film evaporator (WFE) is a type of heat exchanger used primarily for separating volatile components from a liquid mixture by evaporation. It features a thin film of liquid that is continuously wiped across a heated surface, enhancing heat transfer and evaporation efficiency. This process is ideal for handling heat-sensitive materials, such as oils, solvents, and food concentrates, since the short residence time minimizes the risk of degradation.

The wiped film evaporator is commonly used in industries like pharmaceuticals, food processing, petrochemicals, and biotechnology for applications like distillation, concentration, and deodorization. It operates under vacuum conditions to reduce boiling points and prevent overheating, providing a more controlled and efficient evaporation process
