Fluid bed technology – ideal for particle engineering with granulation and coating

A fluidized bed occurs when process air flowing upward lifts a layer of solid particles, fluidizing the particles. The process air is used to generate the fluidized-bed state, and also supplies the required thermal energy for the particle processes at the same time.
In addition to the thermal treatment of solid materials, fluidized-bed processes are used for drying tasks, for forming granules from powders (spray agglomeration) or liquids (spray granulation), and for the coating of particles (spray coating).
All particles are always mixed together so intensively that a uniform treatment temperature is ensured across the entire fluidized bed. This enables not only a drying process that is very easy to control, but also the gentle handling of temperature-sensitive materials.
