Filter-dryer working principle
The Nutsche filter dryer comnines two process operations, filtration and drying, in a single piece of equipment. Filtration liquid-solid separation and agitated vacuum drying allow batch manufacturing of chemical and pharmaceutical products.Filter dryer can also be used for other process such as vegetal extraction.
Features
Batch filtration-drying processes can be in the follow steps
1.Filling
The vessel is filled with a slurry(liquid/solid mixture), generally fed from a reactor or crystallizing tank.
2.Filtration
A liquid/solid separation process takes place through the filtration media ,Filtration(solvent) are collected beneath the filter plate.
3.Piston displacement washing
Washing liquid are used to wash the product cake ,Avolume of liquid is displaced through the cake.washing it.
4.Reslurry washing
The agitator is used the re-slurry the solid in a washing solvent.
5.Smoothing
The agitator is used to smooth the wet cake in the filter dryer, to avoid the formation of cracks or preferential paths.
6.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.
7.Discharging
The specially designed agitator pushes the product out towards a side discharge port.
