Fluid Bed Processing and Formulation

About the 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.

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.


Provisional programme

Day 1. Basic Science and Understanding

  • introduction to fluid bed processing

  • fluidisation basics

  • benefit of mass transfer in the fluid bed

  • particle agglomeration in fluid beds

  • fluid atomisation in fluid beds – basic science mechanisms

  • use and characteristics of twin fluid nozzles in fluid beds

  • importance of powder material properties in fluid beds

These topics will be underlined with three different demonstrations.

Day 2. Applications and Case Studies

  • basics of fluid bed design

  • basic modelling for fluid bed processing

  • fluid bed drying – mechanistic modelling and scale-up

  • how liquids spread, coat or agglomerate in fluid bed processing

  • case studies of continuous and batch operation

  • powder morphology and powder performance – case study food 1: three-in-one coffee mix

  • particle engineering and characterisation of output particles

Three further practical demonstrations will take place on day two and the day will end with a discussion and problem solving forum.

Day 3. Applications and Case Studies continued plus New Developments and Innovations

  • powder morphology and powder performance – case study food 2: thicken-up clear
  • case study on fluid bed granulation modelling and scale-up

  • case study on particle coating and controlled release

  • case study on combining spray drying with a fluid bed

  • innovation example 1 – academic – structured fluid beds: towards more responsive processes

  • instrumentation and control: sensors, soft sensors and control loops

  • innovation example 2 – industry – high gravity fluidized beds
