Patent ID: 7727464

Claim:
A process for operating a packaging transport system, comprising the steps of: sterilizing objects packed in at least one layer of packaging which is bacteria-impermeable and gas-permeable; placing the sterilized objects packed in at least one layer of the at least one layer of packaging into an evacuable sterilization chamber in the form of a transfer lock; pre-evacuating the sterilization chamber at a speed, wherein the speed of the pre-evacuation is adapted to the flow resistance of the gas-permeable packaging to ensure a gas pressure within the packaging remains above a pressure in the sterilization chamber during the pre-evacuation; applying abruptly a vapor mix consisting of water steam and hydrogen peroxide steam as a condensate layer onto the outer side of the packaging; re-evacuating the sterilization chamber to remove the condensate layer and the uncondensed vapor mix before either the vapor mix or the condensate layer penetrates through the packaging to the objects at an inadmissible level; and transferring the sterilized objects and packaging into a sterile clean room.
