Fluid bed technology is a core technology of GEA process Engineering. We supply several different fluid beds for application within food and dairy products, chemicals and pharmaceuticals - all applied for drying, after drying or cooling of particles - powders, agglomerates or pellets - and for production of agglomerates and granulates.

Different types of fluid beds

Fluid bed dryers are applied for particles between 50 microns and 5 mm. There are different types of fluid beds:

  • Back mix fluid beds: For powders that are not fluidizable due to high moisture content
  • Plug flow fluid beds: For powders that are directly fluidizable. Here the design is important for achieving the controlled residence time that is the pre-requisite for obtaining the right particle properties. The plug flow fluid bed can be either stationary or vibrating like the GEA Niro VIBRO-FLUIDIZER™.

GEA Process Engineering supplies both types of basic fluid beds designed to fit into the spray drying process or as a stand-alone unit for other processes.
