In order to maintain good drying effect and […]

Key Points Of This Chapter   The granulation process is actually about finding the balance point between spray and evaporation, as well as the relationship between particle growth and fluidization parameters. This seemingly simple process is not simple in actual application because, as mentioned before, pharmaceutical fluidized bed applications are still in a “blind box”

Key Points Of This Chapter   The selection of the process is based on the characteristics of the API and the properties of the excipients, which must be comprehensively considered through reasonable evaluation methods. When there are many influencing factors, in order to find CQAs more quickly and effectively, it is necessary to conduct DoE
