Breaking Down the Differences Between Wiped Film Evaporators and Thin Film Evaporators
Wiped film evaporators and thin film evaporators are two types of industrial evaporators that are used to separate, concentrate, or purify liquids in a variety of industrial applications. While both types of evaporators operate on similar principles, there are some key differences that set them apart. In this blog post, we'll explore the similarities and differences between wiped film evaporators and thin film evaporators to help you determine which might be right for your industrial processing needs. How Do Wiped Film Evaporators Work? Wiped film evaporators consist of a cylindrical vessel with a heating jacket and a rotor fitted with closely spaced blades or wipers. The liquid to be evaporated is fed into the top of the vessel and flows down the inside of the cylinder as a thin film. The rotor rotates at a high speed, which causes the wipers to constantly wipe the liquid film off the walls of the vessel, creating a thin film that is heated by the jacket. The heat causes the li...
