Schematic Fluid Bed Dryer Isolators 22LRSchematic Engineering Industries design and manufacture barrier isolators with integral Fluid Bed Dryers (FBD's).

Fluid bed dryers are extensively used in the pharmaceutical industries to reduce the moisture content of pharmaceutical powder and granules.

The equipment works on a principle of fluidization of the feed materials

The fluidization process works with hot air introduced at high pressure through a perforated bed of moist solid particulate. The wet solids are lifted from the bottom and suspended in a stream of air (fluidized state).

Heat transfer is accomplished by direct contact between the wet solid and hot gases and the vaporized liquid is carried away by the drying gasses.
