Patent ID: 7431900

Claim:
A peroxy vapor system including: a liquid peroxy solution interface for receiving a source of liquid peroxy solution; a clamping unit which receives and clamps a desiccant cartridge through which air is drawn to dry the air a vaporizer for vaporizing the liquid peroxy solution and entraining the vapor in air; and, a replaceable desiccant dryer removably connected with the vaporizer for drying the air in which the vapor is being entrained, the desiccant dryer including: a tubular chamber with end closures at either end; a desiccant material which absorbs water vapor in the tubular chamber; an inlet a aperture defined in one end closure and an outlet aperture defined in an opposite end closure; annular gaskets surrounding the apertures of the end closures; a piston mounted in one of the end elements, the piston having a sealing face for engaging one end of a desiccant cartridge in a sealing relationship therewith; a means for retracting the piston to facilitate removal of a saturated desiccant cartridge and receipt of an unsaturated desiccant cartridge a screen element at each end aperture for retaining the desiccant material within the tubular chamber; and removable, peel-off, and water vapor impermeable seals closing the end apertures to prevent ambient humidity from being absorbed by the desiccant material before the seals are removed.
