Fluidized Bed Dryers and Finger Bags – Step by Step
We are going to discuss fluidized bed dryers, their construction, working, FBD finger bags, finger bag MOC, and their features and application in pharmaceutical manufacturing. Drying in pharmaceutical manufacturing involves removing water and other liquid solvents from granules or other materials using heat and a stream of air. A fluid bed dryer is used to dry granules in pharmaceuticals using FBD finger bags.
The principles of Fluidized Bed Dryer (FBD):
Now we look at The principles of Fluidized Bed Dryer (FBD):
In the fluidized bed dryer, hot high-pressure air is passed through a perforated bottom of the container containing the granules to be dried.
FBD finger bag.
The granules are lifted from the bottom and suspended in the air stream, this condition is called fluidized st...
