A sterilizing apparatus includes an enclosure defining an interior chamber and a door for accessing the interior chamber. A fluid source communicates with the chamber to supply a working fluid thereto. A heater heats the fluid in the chamber and a pump moves the fluid in the chamber by the heater. A valve communicates with the chamber and with the exterior of the chamber and is configured to vent the fluid in the chamber to the exterior at a pressure of approximately one atmosphere. Such provides superheating and concentrating of the working fluid in the chamber. A method of sterilization includes introducing a working fluid into an interior chamber and circulating the fluid through at least one recirculation loop having a heater for heating the fluid to an operational temperature suitable for killing microorganisms. The method further provides for killing of very high temperature resistant microorganisms.

Apparatus and method for sterilizing items

A sterilizing apparatus () includes an enclosure () defining an interior chamber () and a door () for accessing the interior chamber (). A fluid source () communicates with the chamber () to supply a working fluid thereto. A heater () heats the fluid in the chamber () and a pump () moves the fluid in the chamber () by the heater (). A valve () communicates with the chamber () and with the exterior of the chamber () and is configured to vent the fluid in the chamber () to the exterior at a pressure of approximately one atmosphere. Such provides superheating and concentrating of the working fluid in the chamber (). A method of sterilization includes introducing a working fluid into an interior chamber () and circulating the fluid through at least one recirculation loop () having a heater () for heating the fluid to an operational temperature suitable for killing microorganisms. The method further provides venting of the fluid from the chamber () so as to maintain the pressure at approximately one atmosphere. The method further provides for killing of very high temperature resistant microorganisms.

An apparatus () for generating superheated steam capable of reducing or eliminating microorganisms associated with an item () includes a gas heater () for heating a gas, a steam generator coupled to the gas heater () and having a reservoir () for supplying water, wherein the heater () heats the gas such that when water is combined therewith, a mixture of superheated steam and gas capable of reducing or eliminating microorganisms is discharged from the apparatus (). The generation of the steam-gas mixture may be done at one atmosphere of pressure and the mixing may be done prior to expelling the fluid from the apparatus (). The apparatus () may be configured as a hand-held device, A method of treating an item () for microorganisms includes generating a superheated steam at approximately one atmosphere of pressure, directing a flow of the steam onto the item (), and reducing or eliminating microorganisms using the steam.
