Scale-up and Process Transfer of Freeze-Drying Recipes
This paper proposes a simple and effective methodology for the scale-up and process transfer of freeze-drying recipes. Process modeling allows studying in silico product evolution in a given freeze-dryer, and calculating the operating conditions that results in the same product dynamics in a different equipment. Few experiments are necessary to determine model parameters and to characterize the two freeze-dryers. The problem of the batch nonuniformity and the effect of parameters uncertaintydoi:10.1080/07373937.2011.597059 fatcat:hzqj4qa5u5csdp7v7gwsev56xa
