A filter dryer is a piece of process equipment used during the filtration and drying phase of a pharmaceutical, bio pharmaceutical or chemical process for an active pharmaceutical ingredient or other compounds production.Filter dryers are designed for washing and isolating solids with or without integrated containment systems.
Several actions have to be undertaken as part of the filtration and drying process including:
An agitated nutsche filter dryer is one class of such filter dryers that has been specifically designed so all these operations can take place within one vessel.
A Turbo Filter-Dryer is another class of filter dryer which also incorporates the listed operations, but works on a different set of filtration principle.
