Abstract
A microwave continuous heating apparatus is provided with a heating compartment having openings at its front and rear portions and a transfer device which carries a to-be-heated object held thereon through the heating compartment, and microwave electric power is irradiated onto the to-be-heated object that passes through the heating compartment to heat the same. Two microwave absorbing compartments, through which the to-be-heated object passes, are connected to the front and the rear portions of the heating compartment, respectively. A plurality of reflecting plates of metal which are spaced from each other in a forward-and-backward direction are transferred by the transfer device. The object to be heated is placed between two adjacent reflecting plates. The reflecting plates are placed on the transfer device so that at least one reflecting plate is positioned in each microwave absorbing compartment, at least during irradiation of microwaves into the heating compartment.
