Abstract
Abstract
The possibility of using a gas discharge plasma for sterilization of freeze-drying products directly in the process of their vacuum packaging for long-term storage is considered. An alternating current electrical discharge was used as a source of sterilizing action. In order to increase the homogeneity of the processing of the products, sound waves were applied to the electrical discharge. The effect of acoustic effects was investigated in the pressure range from 10 to 100 Torr, and the sound frequency from 50 to 400 Hz. A noticeable effect of sound waves on the discharge behavior was identified and optimal conditions were determined for increasing the uniformity of the sterilizing effect on the processed products.
