ABSTRACT:
A plasma-enhanced vacuum drying method is disclosed. It is advantageously applied in plasma sterilization processes in particular, and represents a significant improvement for general evacuation drying methods. Articles to be sterilized are placed in a sealed chamber and the chamber is evacuated. A plasma of residual gas species is generated in the chamber during an initial evacuation step. This promotes drying of the articles and advantageously allows a desired pressure to be attained more quickly than without the plasma. Sterilizing gas is injected into the chamber, and a second plasma is generated to activate the sterilizing gas plasma, thereby sterilizing the articles in the chamber.
