Abstract
A microwave heating method using a microwave, including: controlling a frequency of the microwave, to form a single-mode standing wave; disposing an object to be heated in a magnetic field region where a strength of a magnetic field formed by the single-mode standing wave is uniform and maximum; and heating the object to be heated by magnetic heat generation by magnetic loss caused by an action of the magnetic field of the magnetic field region, and/or induction heating by an induced current generated in the object to be heated due to the magnetic field of the magnetic field region.
Claims38
A microwave heating apparatus including:
- a cavity resonator being a microwave irradiation space of a cylindrical type or a polygonal tube type where two parallel surfaces face each other with a tube central axis as the center, excluding a tube type whose cross-section in a direction perpendicular to the tube central axis is a rectangle;
- and
- a transfer mechanism configured to supply an object to be heated of a magnetic substance, or a magnetic loss material or conductive material, or an object to be heated of a composite material including a magnetic substance, or a magnetic loss material or conductive material, into a space where energy distribution of a magnetic field in the cavity resonator is uniform in such a manner as to pass the object to be heated through a magnetic field region where magnetic field strength of the cavity resonator is maximum and uniform,
- wherein the object to be heated supplied by the transfer mechanism is heated in the magnetic field region.
