Scaling decisions must be closely related to a large
number of parameters including: apparatus related (e.g. nozzle and
fluidisation chamber dimensions), parameters related to the core
material (such as porosity, mechanical properties and more),
coating solution (e.g. viscosity, surface tension, contact angle and
more) and the type of fluid bed, input parameters, operating
conditions including spraying and fluidisation conditions aswell as
processing time etc.
