ABSTRACT:
A portable smoke-generating apparatus particularly useful for creating special effects in the film-making and entertainment industry has a vaporizing unit consisting of a solid metallic block having an elongate interior vaporizing chamber. A solid metallic vaporizing member having a cross-sectional configuration corresponding to the cross-sectional configuration of the vaporizing chamber is loosely mounted in the chamber. The passageway between the interior walls of the vaporizing chamber and the exterior walls of the vaporizing element provides a very narrow conduit having a very very high surface area/volume ratio of at least 500, and preferably at least 1,000, to ensure rapid complete vaporization of the liquid and production of a white, dry smoke having a very small particle size. Heat is supplied to the vaporizing chamber by either electrical resistance heaters or a combustions torch mounted in one or more designated chambers in the block. Use of a nozzle having an orifice with a diameter of 0.35-0.80" provides flow of adequate volume while retaining sufficient back pressure in the vaporization chamber to provide a strong burst of smoke.
