Fluidised Bed

Fluidised Bed

In the fluidized bed, the drying energy is brought in and the fluidization is achieved by a cross flow of hot gases through a product layer. The fluidized beds can be designed gas-tight for inertization or solvent recovery. Additional contact exchangers may be installed within the product bed to increase the performance per volume. Designs with two or more drying temperature areas, or for final cooling of the product are possible.


Processes: Drying, cooling, heating, calcining or roasting.

Applications: free-flowing bulk solids, from fine powders to thick grain or short fibers which require a short to medium residence time.

Advantages: High evaporation rates with relatively short residence times, careful mechanical treatment, and absence of moving pieces (in static fluidized beds), flexible and adaptable design.
