Abstract：The particle growth mechanism is studied in a batch operational fluidized bed spray granulator of bean powder. The effects on growth rate of the fluidized bed temperature,the excess fluidized velocity,the viscosity and flow rate of the feeding solution, the size and quantity of seed nuclens and the sorts of seed nucleus were investigated. The better process operation conditions were obtained.
