Abstract
Abstract A method and apparatus for humidifying a product in a microbiocidal gas sterilizing process wherein a predetermined amount of water is admitted to the chamber through a capillary tube controlled by a pressure controlled valve, and control system therefor, which is actuated by a decrease in the total pressure within the sterilization chamber below a predetermined value. Once the pressure again rises to said predetermined value, the valve will be closed, thereby permitting a controlled humidity level to be maintained in the chamber.
