Fluidised bed technology

The fluidised bed process is widely used across a whole host of industries. Its application includes not only heat and material transfer procedures that include cooling, drying and calcination, but also complex multi-phase processes, such as agglomeration, spray granulation and coating.


  • Simple handling of solids
  • Intensive mixing of solids

Basic principle
A static bulk of solid particles is fed in at sufficient speed by a stream of gas and broken up, causing individual particles to float: the solid particles seem to 'flow', giving the appearance of liquid. This process is thus referred to as fluidisation (giving the name 'fluidised bed').

    Use of anti-bearding cap nozzles in fluidised bed systems

    Blocked spray nozzles are a widespread problem in fluidised bed systems in which very fine or tacky products are processed. By using ABC nozzles, the pharmaceutical excipient manufacturer DMV Fonterra Excipients has succeeded in avoiding unplanned downtimes. Düsen-Schlick Anti-bearding cap technology (ABC nozzles) is well-established in the field of tablet coatings.
