Microwave continuous heating apparatus

A microwave continuous heating apparatus 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, whereby the object to be heated is irradiated with microwave electric power during passing through the heating compartment to heat the same, comprising
• microwave absorbing compartments connected to the front and the rear portions of the heating compartment so that the object to be heated can pass therethrough;
• and
• a plurality of reflecting plates of metal which are spaced from each other in a forward and backward direction and which are transferred by the transfer device, wherein the object to be heated is placed between two adjacent reflecting plates, and 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 microwave electric power in the heating compartment,
• wherein the to-be-heated object and the reflecting plates are supplied onto the transfer device in the vicinity of an entrance of the microwave absorbing compartment provided at the front of the heating compartment, and are removed from the transfer device in the vicinity of an exit of the microwave absorbing compartment provided at the rear of the heating compartment, and
• wherein the reflecting plates are made integral with a jig on which the to-be-heated object can be placed, at a front end or a rear end, or both the front and rear ends of the jig.

• shutters provided at the front and rear openings of the heating compartment;
• and a plurality of reflecting plates which are arranged in a line with the objects to be heated, in a transfer section between the vicinity of an entrance of the microwave absorbing compartment provided at the front of the heating compartment and the vicinity of an exit of the microwave absorbing compartment provided at the rear of the heating compartment, wherein the front and rear shutters are opened when the frontmost to-be-heated object or the reflecting plate of the line reaches the vicinity of the shutter, and are closed when the rearmost to-be-heated object or the reflecting plate of the line passes through the shutter, wherein the reflecting plates are secured to a jig on which the object to be heated can be placed, at a front end or a rear end, or both the front and rear ends of the jig.
