Fluid Bed Processing and Formulation

About the course

Please note that due to Covid-19 we may be unable to run hands-on, face-to-face lab demonstrations during this year’s Fluid Bed Processing course.

Fluidised beds are widely used in industry due to their characteristic fluid like properties of good mixing and heat transfer. Applications of fluid beds range from combustion in power stations, catalytic reactors to the engineering of particles via methods such as low density agglomeration and encapsulation.

This new course focuses on the use of fluid beds in particle engineering area and covers:

  • the basic principles behind fluidisation

  • the importance of particle properties

  • the impact of bed design on the structure and optimal operation of fluid beds, both batch and continuous.

The course is grounded in practical experience gained across numerous industrial sectors by a range of speakers from academia, equipment manufacturers and end users. The scientific principles of fluid bed operation will be reinforced by a number of practical demonstrations which show the theory in practice.

Expected outcomes
On completion of this course you’ll be able to:

  • apply an understanding of how material properties, operating parameters and equipment design can have an influence on product properties
  • manipulate operating parameters to influence materials properties and quality parameters
  • recognise how fluid bed processes can be scaled up and appreciate the challenges in start-up and shut down
  • understand how scientific principles can be applied to the processing of real industrial products for better performance, quality and economics
  • learn from how challenges are tackled across different industries
  • choose and design appropriate equipment for fluid bed processing
  • learn from extensive academic and industrial experience, demonstrations, theory and real industrial case studies
  • and, importantly learn from attendees what others are doing in the field of fluid bed processing

Who should attend?

This course is suitable for you if you’re:

  • a R&D scientist working in industries such as pharmaceuticals, detergents, foods, agrochemicals or specialty chemicals and need a broad overview of the subject of fluid bed processing

  • a scientist or chemical engineer who would value a deeper understanding of how science can be applied to real fluid bed processing problems

  • a process technologist, plant manager, involved in R&D or a process technician who needs a thorough practical grounding in the subject of fluid bed processing and how it can influence the properties of the final product

  • a university researcher who requires a deeper insight into real industrial problems, unmet needs and potential new research themes.
