The princiole of FBD Diaries

Numerous organic powders produce electrostatic costs all through drying. To avoid this efficient electrical grounding with the dryer is necessary.

FBD bowl loading: In the tablet producing process, The full Procedure of the Fluidized mattress drier begins With all the loading of wet granular materials within the granulator. The soaked granules to get dried are placed inside the detachable bowl of the vertical FBD.

We'll, thus, encounter loads of problems On the subject of drying sticky components as they don’t shift freely.
