Fluid Bed Drying Myths and Misconceptions: Clearing the ... - Witte

A second common misconception is that a fluid bed dryer doesn’t work well when drying fine, light-weight particles. This thinking likely derived from the fact that achieving fluidization requires a given air velocity and depending on the air velocity and particle size distribution, a percentage of the fine particles becomes entrained in the ...

Transferring Tray Drying to Fluid Bed Drying

Apr 13, 2022 The solids bed exists as a dense bed, with particles resting upon one another, and experiencing no relative motion among them. Depending on the quantity and the type of solvent used, it may take anywhere from a few hours to 24 hours to dry the product. In the case of fluid bed drying, the particles are suspended in a hot gas/air stream.

Principle and Working of Fluidized Bed Dryer (FBD)

Principle and Working of Fluidized Bed Dryer (FBD)

Fluidized bed dryer has a high drying rate and the material is dried in a very short time. Material remains free-flowing and uniform. FBD bags are finger-like in structure to increase the surface area of the drying bed that helps to increase the drying rate and decrease the drying time during the fluidized bed drying process.

One way to improve drying efficiency when faced with fluctuating process conditions is to adjust the time allotted to the material in the drying zone, called retention time. The longer the retention time, the more moisture removal that can occur. This can be done by adding pneumatically operated radius gates called autoweirs.

Spatial Footprint. Rotary dryers are typically larger than fluid bed dryers, and therefore require a larger spatial footprint in the processing plant. Fluid bed dryers are smaller, and have the advantage of being modular, allowing them to be added on to, and making them ideal for situations where there is potential for operational growth.

The high rate of heat and mass transfer achieved with a fluid bed dryer ensures much faster and more homogeneous drying than obtained using other methods; such as oven and vacuum drying. Complete drying is usually achieved in less than 15 minutes, with the exact time for a given sample being very repeatable.
