Agitated Nutsche Filter (ANF)
VOLUME AVAILABLE: up to 300,000L.
Agitated Nutsche Filters (ANF) are designed for operation where maximum percentage of liquid in a slurry is separated through mechanical means. The filter works as a completely closed system preventing cross-contamination, possibility of atmospheric pollution from toxic fumes/obnoxious smell generated from the slurry for API, Herbal Extractions, Chemicals and Food Industry.
- Very high solvent recovery.
- Eliminates Explosion/fire hazard from spillage due to closed system.
- Optimisation of Manpower. All operations can be handled by a single trained person.
- Very effective washing of cake due to re-slurring resulting in thorough particulate washing.
- Reduces number of washes, and volume of wash liquor.
- Possibility of doing reaction, filtration, washing and distillation in the same equipment
- Available in special construction for sterile applications with high standard of particulate purity.
Note: Sizing, selection of configuration, M.O.C’s, methodology of filtration etc. are based on material characteristics and these are used for proper selection and design based on specific application requirements. Magtech has vast experience and Pilot Plant facilities which are offered.

Operations:
Slurry is fed into the top compartment from where filtrate passes into the lower chamber enroute to receiver. Solids are deposited on the filtering media in the top compartment and take the shape of cake of a uniform thickness. The agitator pushes the solid content in the slurry upwards by keeping it under suspension till maximum possible filtrate passes through the filter bed. This reduces time and Increases productivity. It then seals the cracks in the cake, which develop after most of the filtrate has passed through by smoothening the top surface of the cake. It also squeezes out some of the moisture in the cake by slightly pressing the cake uniformly with the help of specially designed blades. After the initial solvent/mother liquor has been separated, sometimes it is necessary to wash the cake. The Agitator has been designed in such a way that after adding wash liquor on the cake, the entire cake can be re-slurred and agitated, so that all the particles forming the cake can be exposed to wash liquor and be thoroughly washed. This improves the quality of the finished products. After washing and removal of wash liquor, the cake can be discharged through a quick opening side discharge door, by rotating and lowering the agitator in the discharge direction. No manual handling is required.
