Abstract
The present invention relates to a technical field of microwave heating, and more particularly to a microwave frequency-selective heating device and a method thereof. The microwave frequency-selective heating device includes: a heating chamber with a microwave feed-in device, and a frequency controller; wherein the frequency controller is connected to the microwave feed-in device. According to the microwave frequency-selective heating device and the method of the present invention, the heating frequency is adjusted by setting the microwave adjusting device, which improves a material heating uniformity while greatly increases a material microwave absorption rate, so as to solve a heating efficiency problem of the conventional technologies. According to the present invention, the frequency for the heated material is intelligently selected by the micro-processor of the microwave adjusting device, and then fed in after being adjusted by the frequency control circuit, which is effective and convenient.
