wiped film molecular distillation
Wiped film molecular distillation is an advanced technique used for the separation of high boiling point, heat-sensitive, and easily oxidized substances. It operates on the principle of differential evaporation, where the molecules with lower boiling points evaporate and are then condensed, leaving behind the more volatile components. The main function of this process is to purify complex mixtures without causing degradation, which is crucial in industries that require high purity products. Technological features include a rotating wiper that continually refreshes the surface of the liquid, preventing overheating and allowing for a gentle distillation process. This method is widely used in pharmaceuticals, fragrances, and food processing, where the integrity of the product is paramount.
