Abstract

The purpose of this study was to optimize the granulation process of sodium percarbonate in a top spray conical fluidized bed. Granular particles are obtained by coupling fluidized particles with a solution of sodium percarbonate, and the physical properties of the granules, such as particle size and their distribution, can be increased. The variables studied in
the design of experiment were the fluidization air temperature (T), the spraying pressure (P), the amount of soluble solvent (M), and the concentration of the binding solution (C). Response surface methodology (RSM) was carried out using Design Expert 7 software. The results showed that by increasing the fluidization air temperature and the spraying pressure, the particle size decreased and the particle size increased with increasing solubility and binding concentration. RSM method is able to determine the range for the best production conditions for an acceptable granule size. In this study, an experimental correlation was presented for the size of the granule, in terms of the variables.
