Agitated Nutsche Filter is a closed vessel designed to separate solid and liquid by filtration under pressure or vacuum or in combination of both. The resulting wet cake can be re-slurried and washed thoroughly with water or solvent. The discharge of wet cake is automatic. Drying of wet cake is also possible when drying features are incorporated. The closed system ensures odourless, contamination free and non-polluting working conditions maintaining product purity and hygiene.
This equipment is extensively used in Chemical, Herbal, Pharma, Agro Chemical & Food Industries.
High drying efficiency and low energy costs.
Direct drying and no initial diluting.
Continuous processing with short drying time.
Slurry is fed into the top compartment from where filtrate passes into the lower chamber en route 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. It then seals the cracks in the cake, which develops after most of the filtrate has passed through, by smoothening the top surface of the cake.
The filter 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 separation of solvent/mother liquor and if the cake requires washing, the entire cake can be re-slurried and agitated, so that all the particles forming the cake can be exposed to wash liquor and be thoroughly washed through the specially designed agitator. This improves 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 agitator in the discharge direction. No manual handling is required.
