METHOD AND APPARATUS FOR VAPORIZING STERILANT HYDROGEN PEROXIDE

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for vaporizing hydrogen peroxide, by which the possibility of diluting vapor-phase hydrogen peroxide from a preset desired concentration is reduced or eliminated and rapid 'heat-up' and a controlled vapor-phase hydrogen peroxide temperature are permitted.;SOLUTION: The apparatus comprises a conduit for a predetermined mixture of atomized hydrogen peroxide and air within a heat exchanger. The heat exchanger is a conduit for a pressurized steam and comprises an inlet for the steam and an outlet for condensation formed by cooling steam. As the pressurized steam surrounds the conduit, heat is transferred to the atomized hydrogen peroxide and air to vaporize the mixture. An outlet for hydrogen peroxide vapor is provided at or near a sterilization location in a packaging machine to allow the vapor to aid the sterilization of packaging.;COPYRIGHT: (C)2003,JPO
