For example, the optimal granulation process settings of the small fluid bed (10% (w/w) powder bed moisture content at droplet size of 0.9 ) would give the same granule size on the medium fluid bed at the same powder bed moisture level, but at a larger droplet size (around 1.1, see Fig. 7). By scaling the granulation process to the large fluid ...

Fluidized bed - Wikipedia

A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid.This is usually achieved by the introduction of pressurized fluid through the particulate medium. This results in the medium then having many properties and ...
