Coffee Fluidisation Video's at Different Roast Times

These are videos of the coffee bean fluidisation experiments collectively done by Joshua Jose and Cameron Mudley under the supervision of Dr. Neil Stacey at the University of the Witwatersrand. The purpose of the coffee bean fluidisation experiments were to validate the ability of the variable diameter fluidised bed reactor to design model to predict the incipient fluidisation velocities and fluidisation velocities at a speciefied voidage of 0.6.
