Abstract
A method of drying an object comprising, providing an object into an RF cavity; applying broadband RF energy to the object in controlled manner which keeps the object within a desired temporal temperature schedule and within a desired spatial profile; and terminating the drying when it is at least estimated that a desired drying level is achieved.
Claims54
A method of drying an object in a cavity using RF energy radiation, the method comprising:
- applying RF energy to the object;
- obtaining a spectral image, comprising input efficiency to the cavity as a function of frequency, based on coupled power between first and second antennas;
- and
- adjusting the application of RF energy based on the spectral image.
1 more element
A dryer, comprising:
- a cavity to receive at least one object to dry;
- at least one RF source configured to radiate RF energy into the cavity;
- and
- a controller configured to:
- obtain a spectral image comprising input efficiency to the cavity as a function of frequency, based on coupled power between first and second antennas;
- and
- control the at least one RF source to dry the object based on the spectral image.
