One-pot processing is a term that includes any technology that combines different unit operations of a pharmaceutical production process into one machine.

The requirements of a granule drying process haven't really changed much in recent years.

This article describes the use of a one-pot processor for the cleaning and cleaning validation of two drug compounds - water-soluble theophylline and water-insoluble mebendazole. Both substances were produced using wet granulation and microwave drying, after which the processor was cleaned using its clean-in-place (CIP) system. Swab samples were taken from areas considered critical during processing and analysed for remains of active ingredient. It was concluded from the results that the processor's CIP system is capable of removing both moieties to a level well within accepted regulations.
