ABSTRACT:
A method of drying articles is presented. The method generally comprises fluidizing solid media, contacting the article with the fluidized media for a sufficient amount of time to allow liquid to be transferred from the surface of the article to the solid media. Typically this involves forming a bed of solid material, fluidizing the bed then immersing the article to be dried in the fluidized bed. Using solid media to contact the wet parts, the water, and anything dissolved in it, is wicked away. The parts are dried in seconds with little residue and no heating. The solids used are typically porous and have very high surface area and can therefore be rapidly dried and reused.
