The process of solid formation during spray drying has been described many times in the literature, however, a detailed mathematical description of the time‐dependent process concerning the structure of the particles as a function of substance and process parameters is still not available. In the present work, a time‐dependent and local modeling of the mass and energy transport processes during solid formation inside the droplet was carried out. The model was validated against reproducible experiments performed in a vertical pipe with single drop generation.
