Agitated Nutsche Filter Dryer
The Agitated Nutsche Filter Dryer (ANFD) is a versatile, closed-system equipment used for solid–liquid separation, cake washing, and drying in a single, compact unit. Designed for handling toxic, hazardous, or solvent-laden products, the ANFD ensures safe, efficient, and contamination-free operations under vacuum or pressure.
The system consists of a filter plate with a special filter media, a jacketed vessel for heating/cooling, and a multi-purpose agitator. The agitator not only assists in uniform cake drying but also enables reslurrying, smooth cake discharge, and efficient mixing during washing cycles. With vapour-tight construction and optional inertization, ANFDs are ideally suited for pharmaceutical, chemical, and specialty industries where product purity and operator safety are critical.
By combining multiple process steps into one machine, ANFDs reduce equipment footprint, minimize material handling, and deliver superior process efficiency.
