“…Comparing these results with experimental investigations on the morphology of spray dried granules, the model reaction on the liquid particle merging threshold can be linked to the binder concentration. Eckhard et al found that the microporosity is increased at elevated binder contents [1]. Moreover, their investigations also indicated an earlier stop of droplet shrinkage with increasing binder content and therefore larger granule sizes.…”

“…During evaporation the retarding solids form a porous particle due to agglomeration of the initially dispersed primary particles. The final product morphology is affected by various factors as, e.g., shown by Eckhardt et al [1]. They experimentally demonstrated that dense as well as hollow granules with varying mechanical properties emerge depending on the one hand on the feed formulation, on the other hand on process parameters.…”

Dedicated to Prof. Dr. Thomas Hirth on the occasion of his 60th birthday Spray drying is a widely used process to obtain solid porous products from a liquid feed. Whereas the product's morphology is important for its further processing, established one-dimensional single droplet models are limited in predicting the final structure depending on drying conditions and functional additives as binders. A novel approach based on a meshfree method is employed to calculate the final morphology from first principles by accounting for physical effects like surface tension and wetting. Generation of dense porous products and buildup of hollow particles with a porous crust can be modelled, depending on the model parameters.
