ABSTRACT:
Biocidal gas sterilization methods and apparatus are disclosed in which goods are heated and moisturized prior to addition of the sterilizing gas utilizing repressurization after initial evacuation to provide drive power for the conditioning vapor and improve conditioning efficiency. After initial evacuation to a selected subatmospheric pressure level, the chamber is repressurized with a conditioning vapor comprising steam to a subatmospheric pressure level corresponding approximately to desired sterilizing temperature, then the chamber is held with evacuating and vapor injecting interrupted for a predetermined interval; this sequence of steps is repeated a selected number of times; and, conditioning to various sterilizing temperatures is available. Initial evacuation can be accompanied by intermittent injection of conditioning vapor. No chamber measurement of temperature or relative humidity is required for conditioning control and conditioning vapor injection is free of flow rate control requirements.
