JTNB - AGITATED NUTSCHE FILTER DRYER

JTNB Agitated Nutsche Filter Dryer is a high-quality equipment designed for solid-liquid separation processes, by filtration under pressure and vacuum drying, can be use for the pharmaceutical, chemical, fine chemical and food industries.

Within the filtering applications, there are products which, due to their special hazardous or toxic characteristics, or prevent cross-contamination, are more desirably treated in a hermetic way during their manufacturing process.

JTNB Nutsche Filter Dryers have been specially designed to guaranteeing the obtaining of pure substances which are free from polluting elements.Designed in accordance with the GMP standards, for all types of pharmaceutical and fine chemical applications. Our machines are validatable in sterile applications and we have special designs to install inside clean rooms.

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 on mother liquid tank.

3、Washing
Washing liquid are used to wash the product cake , The agitator is 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.
