Static (non-shaking) fluidised bed or fluid bed (dryers and coolers) are used on free flowing fluidised bulk materials that have a narrow particle size distribution. The static fluid bed remains stationary during operation. Static fluid bed dryers can be continuous or batch operation and may be round or rectangular.
The other type of fluid bed dryer is a shaking fluid bed dryer or cooler, where the body of the dryer oscillates, assisting the movement of material through the unit and supporting the fluidisation of the product.
