Laboratory Filter-Dryer Enables Scalability
The GFD laboratory nutsche filter–dryer from Powder Systems Limited, originally developed in glass, is available in metal to allow higher pressures. The laboratory- scale unit can be used for feasibility studies and trials before scaling up to a commercial-scale agitated nutsche filter dryer (ANFD). The stainless-steel 316 L or alloy C22 versions allow better replication of the pressures in commercial ANFD. The Mini Lab GFD unit has a total volume of 0.3 L that can filter a cake volume up to 0.1 L and is suitable for laboratory-scale trials. The Lab GFD size includes a removable filtration basket of 0.01-m² for a cake volume of 0.5 L for small-scale synthesis. The Maxi Lab GFD filters a cake volume of 5 L with 0.05-m² filtration area.
