Abstract
In a dry-processing apparatus, a heat insulating container is interposed between an inner container for accommodating objects to be dried and a condensing outer container which is cooled by a fan. The inner container is made of a microwave transmittable material having excellent heat resistance. The adopted heat insulating container is made of a microwave reflecting material. Microwaves are generated by a microwave oscillator to heat the objects to generate vapor from the objects. The generated vapor contacts the cooled condensing outer container so as to be condensed into water. A temperature sensor is provided at the upper portion of the condensing outer container so as to detect the temperature of the generated vapor to thereby control the heating and drying operation.
