    • The present invention provides a method and apparatus for sterilizing articles using an ozone-containing gas, where condensation of water from the sterilization atmosphere during the sterilization process is substantially prevented. The inventive sterilization method includes providing a sterilization chamber and placing an article into the sterilization chamber. The sterilization chamber is sealed prior to equalizing the temperature of the article and the atmosphere in the sterilization chamber. A vacuum is applied to achieve a preselected vacuum pressure in the sterilization chamber. Once the vacuum pressure is set, water vapour is supplied to the sterilization chamber. Ozone-containing gas is then supplied to the sterilization chamber and the sterilization chamber remains sealed for a preselected treatment period, where the sterilization chamber remains sealed throughout the whole process. Finally, vacuum in the sterilization chamber is released.
    • 本发明提供一种使用含臭氧气体灭菌物品的方法和装置,其中基本上防止了在灭菌过程中来自灭菌气氛的水的冷凝。 本发明的灭菌方法包括提供灭菌室并将物品放入灭菌室。 在均匀化灭菌室内物品的温度和气氛之前密封灭菌室。 施加真空以在灭菌室中实现预选的真空压力。 一旦设定了真空压力,则向灭菌室供给水蒸汽。 然后将含臭氧气体供应到灭菌室,并且灭菌室在预选的处理期间保持密封,其中在整个过程中消毒室保持密封。 最后,消毒室中的真空被释放。
