Fluid Bed Dryers & Coolers
The CONTACT FLUIDIZER Fluid Bed is the solution for very large-scale fluid bed drying of wet powder chemical bulk products. It has a compact design, high thermal efficiency, and low gas throughput.


Wet powder is introduced into the back-mix section of the CONTACT FLUIDIZER where evaporation starts and the powder becomes directly fluidizable. The proprietary Rotary Feed Spreader ensures the continuous uniform distribution of the wet feed material that is a prerequisite for maintaining the ”homogeneity” of the back-mix section and thereby its performance. The semi-dried powder enters the plug flow section, where the powders' residence time is fully controlled. If, as a final step, product cooling is required, the fluid bed is extended with a plug flow section equipped with internal cooling panels.
The gas required for the fluidization of the powder is distributed by the GILL PLATE, tailor-made for the individual plant, to ensure even gas distribution over the bed, good transport of lumps and effective emptying of the fluid bed at shut-down.
When it comes to thermal efficiency, the heating panels submerged into the fluidized powder layer make the design unique because of its highly effective method of transferring the heat from the panels to the powder through the fluidizing gas.
Whether it’s a fad or the future, 100% vial traceability is becoming an increasingly important consideration in the pharmaceutical freeze drying industry. Keeping a close eye on developments is GEA. We’re investigating possible solutions and, what’s more, we have the experience, expertise and know-how to implement them.
There was a time when the phrases ‘non-alcoholic beer’ and ‘tastes good’ were seldom used together in the same sentence, particularly by consumers. But low-proof and alcohol-free beers have come a long way – many of them now refreshing drinks in their own right – thanks in no small part to technology from GEA.
At GEA, our commitment to engineering for a better world fuels our pursuit of innovative solutions that enhance patient care and safety. One of our most promising ventures in recent years is aseptic spray drying – a technology that promises to revolutionize pharmaceutical manufacturing.
