Abstract
A pressure-vacuum purge cycle that is employed in the sterilization of dry goods and especially of wrapped fabric packs employs a positive pressure steam pulse followed by a positive pressure steam displacement of continuously vented air in novel combination with subsequent vacuum pulsing at limited maximum negative pressures to provide improved conditioning of the said goods in respect of the purging of air and moisturizing of the goods and improved economies in time and energy consumption.
