Kontinuierliche Wirbelschicht‐Sprühgranulation

Continuous fluidized bed spray granulation. Spray granulation in a fluidized bed can transform originally liquid products (suspensions, melts, solutions) into freeflowing, largely dust-free granular solids. In the ideal case, the process steps of nucleation, drying/crystallization, shaping, and selective exiting of those particles which have reached the desired size proceed simultaneously in a single unit. The present contribution describes the state of the art of this process as presented in the literature.
