A new model for the drying of droplets containing suspended solids after shell formation

Simulation of the influence of surface tension on granule morphology during spray drying using a simple capillary force model

“…However, in the majority of the reports, both experimental [4-7, 2,3] and simulation [9][10][11][12][13][14]17,18], the influence of surface tension has not been studied in any detail. It was part of the idea of this study to close this gap using simulations, but on the other hand, this lack of experimental data makes it hard to carry out immediate validation of the results by experimental data.…”

“…This continuum mechanical approach allows e.g. for distinguishing between wet and dry shell and enables the simulation of shell growth [13] and even provides some insight in the granule morphology [14].…”

Influence of Feed Composition and Drying Parameters on the Surface Composition of a Spray-Dried Multicomponent Particle

“…Depending on drying conditions, various particle morphologies can be created, of which so far only few were modeled [15,16]. The aim of this model is to predict the time of shell formation and to be able to track the component gradients in a droplet because they determine the surface composition of a particle.…”

Simulation of the Spray Drying of Single Granules: The Correlation Between Microscopic Forces and Granule Morphology

“…Another class of models use a stochastic description of the suspended particles based on a population balance. 13 This approach allows, for example, distinguishing between wet and dry shell and enables the simulation of shell growth 14 and even provides some insight regarding the granule morphology, 15 albeit still on an averaged level, that is, without specific details of the microscopic structure and variations in the particle distribution. In summary, none of the above approaches can provide detailed information about the evolution of the granule morphology on the level of solid particles.…”
