Extruders are typically used for product degassing. In extruders highly viscous substances are compressed and simultaneously freed of solvents. The vacuum pump used serves exclusively to evacuate low boiling point solvents as well as any air that has entered the material through leaks.
All medicinal products are dried before entering the marketplace. Solvents are removed from the product in a heatable static or dynamic dryer. The advantage of vacuum drying is that the product can be processed at low temperatures. The temperature always corresponds to the vapour pressure of the solvent being used.
Wastewater that is contaminated with solvents must be treated for environmental reasons. The simplest method is vacuum distilling, where the low-boiling-point fraction is evaporated and then condensed. The wastewater is then transported elsewhere for further use.
