Claims2
A sterilizing method for sterilizing a sterilization object housed in a chamber, the method comprising:
- a first vapor preparation step of evaporating a first aqueous solution of hydrogen peroxide and filling produced vapor in an evaporator;
- a first vapor injection step of injecting the produced vapor to the inside of the chamber from the evaporator;
- an ozone preparation step of filling an inside of a buffer tank with ozone gas;
- and
- an ozone injection step of injecting the ozone gas filled in the inside of the buffer tank to an inside of the chamber,
- wherein the ozone injection step injects the ozone gas filled in the inside of the buffer tank via the evaporator after the first vapor injection step, thereby forcing a portion of the produced vapor of the hydrogen peroxide remaining in the evaporator into the chamber.
