Gasifier for sterilizer
To provide an apparatus that can gasify a sterilizer containing hydrogen peroxide to produce a gas having a high hydrogen peroxide concentration. The apparatus can stably produce a gas of the sterilizer containing hydrogen peroxide for a long time. A heating surface of a heating body that gasifies the sterilizer is made of chromium. Alternatively, the heating surface of the heating body that gasifies the sterilizer may be made of polytetrafluoroethylene or perfluoroalkoxy fluorocarbon resin, or a chromium plating impregnated with chromium polytetrafluoroethylene or perfluoroalkoxy fluorocarbon resin.
1. An apparatus for gasifying a sterilizer, the apparatus comprising:
a sterilizer supplying portion that supplies the sterilizer to the apparatus for gasifying;
a sterilizer evaporating portion that is supplied the sterilizer from the sterilizer supplying portion;
a heating surface that gasifies the sterilizer by contacting the sterilizer, the heating surface being an inner surface of the sterilizer evaporating portion; and
a source of hydrogen peroxide as the sterilizer;
wherein the heating surface is made of chromium and has an arithmetic mean roughness (Ra) of 1.0 μm or less and a ten-point mean roughness of 2.0 μm or less.
2. The gasifier for a sterilizer according to claim 1 , wherein the sterilizer supplying portion is configured to spray the sterilizer to the heating surface included in the sterilizer evaporating portion, and wherein the heating surface has a cylindrical shape.
3. The gasifier for a sterilizer according to claim 2 , wherein the sterilizer supplying portion includes a twin-fluid sprayer.
4. The gasifier for a sterilizer according to claim 2 , further comprising a heated air supplying device that introduces heated air provided at an end portion of the sterilizer evaporating portion.
5. The gasifier for a sterilizer according to claim 2 , further comprising a filter provided at an end portion of the sterilizer evaporating portion.
6. An apparatus for gasifying a sterilizer, the apparatus comprising:
a sterilizer supplying portion that supplies the sterilizer to the apparatus for gasifying;
a sterilizer evaporating portion that is supplied the sterilizer from the sterilizer supplying portion;
a heating surface that gasifies the sterilizer by contacting the sterilizer, the heating surface being an inner surface of the sterilizer evaporating portion; and
a source of hydrogen peroxide as the sterilizer;
wherein the heating surface is made of a chromium plating impregnated with polytetrafluoroethylene or perfluoroalkoxy fluorocarbon resin.
7. The gasifier for a sterilizer according to claim 6 , wherein the sterilizer supplying portion is configured to spray the sterilizer to the heating surface included in the sterilizer evaporating portion, and wherein the heating surface has a cylindrical shape.
8. The gasifier for a sterilizer according to claim 7 , wherein the sterilizer supplying portion includes a twin-fluid sprayer.
9. The gasifier for a sterilizer according to claim 7 , further comprising a heater air supplying device that introduces heated air provided at an end portion of the sterilizer evaporating portion.
10. The gasifier for a sterilizer according to claim 7 , further comprising a filter provided at an end portion of the sterilizer evaporating portion.
