Scale-Up of Drying Processes

As a single-pot processor is often used for highly potent products, or more generally for contained production, it is important that also cleaning of the machine can be executed in a contained, automated fashion to eliminate the risk of operator exposure to the active product. 

Drying of the single-pot processor after the cleaning cycle to prepare the equipment for the next batch can be done using the system s own vacuum-drying system and jacketed bowl, making a separate drying unit redundant. 

A nice case study of an evaluation of a clean-in-place system on a pilot-scale single-pot processor is given in Ref (3). In this study it was proved that a complete changeover from one product to the next can take place in 2 hr.
