Statistical evaluation of tablet coating processes: influence of pan design and solvent type
Partially and fully perforated pan coaters are among the most relevant types of equipment currently used in the process of coating tablets. The goal of this study was to assess the performance differences among these types of equipment employing a factorial design. This statistical approach allowed...

Partially and fully perforated pan coaters are among the most relevant types of equipment currently used in the process of coating tablets.
