Thin film distillation

Thin film distillation

Thin film distillation, also known as molecular distillation, is a separation technique that involves the evaporation and condensation of substances based on differences in molecular movement properties. It is particularly effective for the separation of heat-sensitive and high-boiling-point compounds. The process works by creating a thin film of the liquid mixture on a heated surface, typically a cylindrical or conical evaporator. As the liquid travels down the heated surface, it quickly evaporates, and the vapor rises to a condenser where it is cooled and collected as the distillate. This method allows for the separation of components with close boiling points and achieves high purity and efficiency due to the short residence time and reduced exposure to heat.

A wiped film evaporator is a specialized type of thin film distillation equipment that enhances the efficiency and performance of the distillation process. It is designed with a rotating wiper system that constantly replenishes the liquid film on the evaporator surface, improving heat transfer and preventing product degradation. The wiper blades or rollers create a thin and uniform film that maximizes the surface area for evaporation. The high shear force generated by the wiper blades helps maintain a turbulent flow and minimizes the residence time, leading to faster evaporation rates and improved separation efficiency. Wiped film evaporators are widely used in various industries, including pharmaceuticals, chemicals, and food processing, for the purification and concentration of heat-sensitive compounds.
