Course description
Fluid Bed Processing and Formulation
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.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.
