Agitated Nutsche Filtering Dryers Structure




Working Principle

1. Filling:The vessel is filled with a slurry, generally fed from a reactor or crystallizing tank.
2. Filtration:A liquid/solid be separated through the filter plate, filtration(solvent) liquid be collected by the liquid tank.
3. Washing:Washing liquid are used to wash the filter core, the agitators used the re-slurry the solid in a washing solvent.
4. Smoothing:The agitator is used to smooth the wet cake in the filter dryer, to avoid the formation of cracks or preferential paths.
5. Drying and cooling:Agitated vacuum drying consists in applying a vacuum on the vessel, while heating the walls and agitator using thermal circuits. This allows to reach the liquid boiling point and to dry the product.
6. Discharging: The specially designed agitator pushes the product out from sterile discharge valve.
