Abstract:
A method for drying a coated material with microwave radiation, the coated material being substantially coated with a solvent, comprising:introducing microwave radiation into a chamber, the chamber comprising:a body, the body comprising an inner surface, the inner surface comprisinga substantially conductive material;a front and rear wall, both the front and rear walls comprising inner surfaces, wherein the inner surfaces of the front and rear walls comprise a substantially conductive material, and wherein the front and rear walls are configured to be substantially reflective of microwaves; andan elongated member oriented in a central portion of the chamber, the elongated member comprising a substantially non-conductive material; andwherein the body, the front wall, and the rear wall together define a cavity, and wherein an interior volume of the cavity and a volume of the elongated member are predetermined such that the interaction of the microwave radiation with the body, the front and rear walls, and the elongated member produces a resonant electromagnetic mode; andpassing the coated material through the chamber at a rate such that the solvent is substantially removed from the coated material.
