Solids vaporizer
Vaporizer vessels include one or more reagent support panels, serving as dividers of interior space of the vessel, in a vertical orientation such as when filling the vaporizer vessels, and when rotated into a horizontal orientation, the panels support the vaporizable solid materials placed in one or more chambers formed by the panels and interior walls of the vessels and enable transfer of heat to those solid materials. The chambers are such that any or all chambers filled with the vaporizable solid materials provide a void space to allow the solid materials to vaporize and for gas to move through the vaporizer vessels when heated, to allow effective vaporization of the solid materials and further allow the vapor resulting from the solid materials to move to an outlet of the vessels where it can be provided as part of a process.
