An Agitated Thin Film Dryer (ATFD) is a type of evaporator that dries highly viscous and heat-sensitive materials by spreading them into a thin film and agitating them on a heated surface. This method ensures efficient heat transfer and rapid evaporation of solvents or moisture, leaving behind a dry product. Various industries, such as chemical, pharmaceutical, food, and wastewater treatment, rely on ATFDs due to their ability to handle challenging drying processes with high efficiency and minimal thermal degradation.
