  • Patent number: 6025580
    Abstract: A method of drying objects includes the steps of placing the objects into a pressure reduction tank, placing a metallic element having a single or plural number of sharp edge into the pressure reduction tank, subjecting the objects to controlled microwave heating and controlled far infrared heating either separately or simultaneously, detecting an electrical discharge at the sharp edge of the metallic element due to microwave energy, stopping or pausing the microwave heating when an electrical discharge is detected at the single or plural number of sharp edge of the metallic element, continuously measuring the change in reduced pressure at prescribed time intervals after the microwave heating has been stopped or paused upon detecting an electrical discharge due to microwave energy, and terminating the drying process when the measured change in reduced pressure reaches a predetermined target reduced pressure change value determined in accordance with the level of dryness selected and the type of the objects be
