Abstract

An apparatus for providing sterilant to a packaging machine is provided. The apparatus comprises a conduit, for a predetermined mix of atomized hydrogen peroxide and air, within a heat exchanger. The heat exchanger is a conduit for steam heat under pressure and comprises and 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 causing the mixture to vaporize. An outlet for hydrogen peroxide vapor is provided at or near a sterilization location in a packaging machine, allowing the vapor to aid in the sterilization of packaging.
