Operating Principle

The Combined Fluidisation Technology dryer (CFT dryer) offers an economic process for sticky products. CFT dryers combine the advantages of convective fluidised bed drying with contact drying.
The CFT works with a hot mechanically fluidised bed. The feed material is distributed into this bed. It is fluidised by a rotating paddle system. Inside the fluidised bed the wet product is evenly distributed throughout the dry product. The volatiles evaporate instantly in contact with the hot particles, i.e. new solids are created at the location of evaporation.

CFT dryers allow the handling of products, which cannot be handled in other types of contact dryers. Highly viscous, pasty, sticky, crust-forming phases do not exist.
