Fluidized bed drying of some agro products – A review
Enhancing the gas–solid contacting inside a fluidized bed leads to improved solids drying characteristics. This can be achieved by mechanical vibration, resulting in so-called vibro-fluidized beds. In this study, experiments in a pseudo-2D vibro-fluidized bed setup are performed in order to better understand this improved drying behavior.

A fluidized bed occurs when a quantity of solid particles (generally contained in a holding vessel, most commonly a fluid bed processor) are placed under appropriate conditions to cause the mixture to behave as a fluid. This is typically done by forcing pressurized air, gas, or other fluids through the bed of solid particles.
