The advantages of the Fluid Bed Dryer, CONTACT FLUIDIZERTM include its compact design, high thermal efficiency and low gas throughput.  

FLUID BED DRYER DESIGN
The rectangular fluid bed dryer system, CONTACT
FLUIDIZERTM incorporates back-mix and plug flow
sections. A rotary distributor disperses the wet feed
evenly over the back-mix section equipped with
contact heating surfaces immersed in the fluidized
layer.

The heating surfaces of this fluid bed dryer are
designed to avoid deposits and obtain a high
heat transfer in the fluidized layer, and they provide
a significant portion of the required energy.

 Fluid Bed Dryer - CONTACT FLUIDIZER
Therefore it is possible to reduce both the temperature and the flow of gas through the system. This is particularly important for heat sensitive products.
Specially designed perforated gill plates allow handling of oversizes and minimize powder holdup by grade changes.

The heating panels can be inspected or cleaned externally.
Cleaning in place (CIP) of the whole plant is often provided.
Subsequent plug flow sections are used for postdrying and cooling, if required.

ADVANTAGES
Advantages of the CONTACT FLUIDIZERTM - compared to fluid beds without heating surfaces, two-stage flash/fluid bed dryers, or rotary dryers - include its compact design, high thermal efficiency, and low gas throughput
