Agitated Nutsche Filter Dryers operate on the principle of filtration, washing, and drying within a single enclosed vessel. The ANFD consists of a cylindrical vessel with a conical bottom and a filter support plate. The vessel is equipped with an agitator that can rotate and move vertically to facilitate the mixing, filtration, and drying process.

The water heated up by the steam gets collected in the preheating section of the deaerator. Once the water level reaches the operating level of the tank, then the steam is passed through a steam pipe into this section. This steam bubble ups through the water thereby heating the water and releasing the non-condensable gases.
