The invention relates to the
microwave heating technology, and discloses a
microwave mode exciting and stirring heating method and a heating device thereof. According to the technical scheme of the
microwave mode exciting and stirring heating method, N
energy feedback ports are divided into M sets and feed back energy to a heating cavity in turn. The microwave mode exciting and stirring heating device comprises the heating cavity, the N
energy feedback ports, a microwave source and a
control system. The microwave source is connected with the
energy feedback ports, and feeds back the energy to the heating cavity through the energy feedback ports. The
control system is used for controlling the feedback energy of the heating cavity. The N energy feedback ports are divided into the M sets and feed back the energy to the heating cavity in turn, wherein N and M are positive integers, N is larger than or equal to 2, and M is larger than or equal to 2. According to the microwave mode exciting and stirring heating method and the heating device thereof, by switching the energy feedback ports feeding back the energy to the heating cavity, the microwave excitation
modes in the heating cavity are changed, the different microwave excitation
modes can excite different
electric field modes in the heating cavity, namely, the number of the
electric field modes in the heating cavity is increased, and the uniformity of
electric field distribution and the heating uniformity are improved. The microwave mode exciting and stirring heating method and the heating device thereof are suitable for industrial heating application of microwaves.
