Apparatus and method for vaporizing oxalic acid crystals to generate oxalic acid gas to treat bee mites

A method for vaporizing oxalic acid crystal comprising the following steps:

• placing oxalic crystals in a chamber of a dispensing module, the chamber having a wall and a first opening through the wall, the dispensing module further comprising an outwardly extending adapter member having a proximal end sealingly attached to a second opening, wherein the outwardly extending adapter member further comprises a distal end and the outwardly extending adapter member has and an aperture extending from the proximal end to the distal end;
• connecting an outlet end of a manually detachable heating module to the distal end of the outwardly extending adapter member, the manually detachable heating module comprising an air receiving inlet and a heating element which heats air flowing from the air receiving inlet to the outlet end and through the aperture to the chamber;
• and
• activating the heating coil to heat the air flowing from the air receiving inlet to the outlet end and through the aperture to the chamber thereby heating the oxalic crystals until the oxalic crystals sublimate into a gas which flows out of the first opening.

An apparatus for vaporizing oxalic acid crystals and dispensing a gas generated from said vaporizing, the apparatus comprising:

• a dispensing module comprising a cylindrical chamber having an wall and a circular top, the dispensing module further comprising an outwardly extending conduit member attached to a front side of the cylindrical chamber, and an outwardly extending adapter member attached to a rear side of the cylindrical chamber, wherein a first end of the conduit member is attached to a first opening through the wall, the outwardly extending conduit member further comprising a second end, the second end comprising a nozzle, wherein the outwardly extending adapter member has a proximal end attached to a second opening through the wall, the outwardly extending adapter member comprising a distal end, the outwardly extending adapter member having an aperture extending from the from the proximal end to the distal end, the dispensing module further comprises a screen member disposed against the wall, the screen member at least partially covering the second opening:
• a manually detachable heating module comprising an outlet end configured to slidingly engage the outwardly extending adapter member, the plastic welder comprising an air receiving inlet and a heating element which heats air flowing from the air receiving inlet to the outlet end;
• and
• a handle member having a first end attached to the cylindrical chamber, the handle member comprising a supporting grip member.
