Flowsheet simulation offers the possibility to simulate a complete process by the application of suitable short‐cut models. In this contribution a novel model for a spray dryer based on a population balance approach is presented. Furthermore, a dynamic model for a fluidized bed dryer is introduced. Experimental data is used for validation and parameter optimization. The calibrated models are then used to design an industrial drying process of multiple drying stages.A multistage drying process consisting of a spray dryer and fluidized beds is designed using flowsheet simulation. A novel modeling approach is presented for the spray drying. The dynamic modeling of the fluidized bed is based on an adaptation of established models. imageen0009-286X2021812871294Wiley-VCH Verl.https://creativecommons.org/licenses/by-nc-nd/4.0/Dynamic modelingFlowsheet simulationFluidized bedPopulation balanceSpray dryingChemieTechnische ChemieDynamic modelingFlowsheet simulationFluidized bedPopulation balanceSpray dryingJournal Article2021-06-1410.15480/882.361610.1002/cite.20200020710.15480/882.3616Other
