This work focuses on the particle properties of sodium benzoate granules, which are produced by fluidized bed spray granulation during different process conditions. The drying process has a decisive influence on the kinetics of the growth rate and thus also on the properties of the particles, like the morphological structure, particle moisture and porosity. This influence has been considered in this project in more detail. In order to compare the produced granules while varying the drying conditions an external product classification is used to achieve a certain product size. The results show that the drying conditions significantly affect the granule morphology and structural properties. Hence, higher spray rates of the suspension and lower drying temperatures lead to higher jaggedness of the product particles.
