Embodiment Construction

[0027] refer to figure 1 ,figure 2, image 3 As in FIG. 4 , steam generation unit 10 vaporizes the peroxygen solution from solution source 12 and entrains the steam in dry air that has been dried by dryer 14 . Dry air and steam are delivered to a processing chamber, such as isolator 16 .

[0028] In the preferred embodiment, the source of the peroxygen solution is a container or cylinder containing an aqueous hydrogen peroxide solution, which is received at the interface portion 20 of the cylinder. After the barrel is positioned at the barrel interface, it can be connected with the dip tube assembly to extract the solution. While steam from aqueous hydrogen peroxide is preferred, other solutions are also contemplated, such as solutions of peracetic acid and water, solutions of other peroxides in water, solutions of peroxides in ethanol and water, and the like. In a preferred embodiment, the solution of hydrogen peroxide and water contains 35-50% hydrogen peroxide.

Abstract

A hydrogen peroxide vapor generation unit ( 10 ) receives hydrogen peroxide and water solution at an interface ( 20 ) and interconnects with an air dryer ( 14 ) by way of nipples ( 72, 92 ). In one embodiment, the dryer includes a clamping assembly ( 42 ) which is latched ( 74, 94 ) with the nipples and which receives a disposable desiccant cartridge ( 40 ). In an alternate embodiment, a reusable desiccant cartridge ( 40 ') is connected directly to the nipples ( 72, 92 ). When the desiccant cartridge ( 40 ') is saturated, it is removed and placed in a regenerator unit ( 120 ). A regenerated cartridge is installed in its place.

Description

technical field [0001] The invention relates to peroxygen steam treatment technology, in particular to hydrogen peroxide steam sterilization and disinfection. The present invention is specifically applicable to a hydrogen peroxide steam disinfection system, wherein the peroxygen steam is entrained in the dry air that has been dried by a desiccant, and will be specifically described below in conjunction with this point. It will be appreciated that the present invention is applicable to other peroxygen vapors related to disinfection, sanitation, and other treatments. Background technique [0002] Heretofore, solutions of hydrogen peroxide and water are vaporized and entrained in dry air. Steam and air are pumped into the sterilization or other processing chamber. Hydrogen peroxide reacts with microorganisms and other detergents in an oxidation reaction, inactivating them and converting vapor molecules from peroxide to water. To maintain a predetermined concentration of hydr...
