Advantages of microwave drying sterilization:
First, the light and vocal. Microwave has the same characteristics as light, mainly in its reflection, linear propagation and clustering. Since the meager wavelength is comparable to or smaller than the length of the radio waves of a radio device and the size of general objects on the earth (such as airplanes, missiles, ships, rockets, cars, buildings, etc.), it is strongly generated when microwaves are irradiated onto these objects. The reflection, based on the reflection characteristics of microwaves, has invented radar systems. Secondly, the microwave can be focused like light to be linearly propagated in space. Therefore, the microwave can form directional radiation through the antenna device, so that the directional transmission or receiving the weak signal transmitted from the space can realize microwave communication or detection. In addition, the microwaves also exhibit characteristics similar to sound, that is, phonological. For example, the microwave waveguide is similar to the acoustic tube in the acoustics, and the antenna is similar to the grading speaker.

Second, penetration. When the microwave is irradiated to the medium, it can penetrate into the inside of the medium and become penetrating. On the one hand, clouds, fog, snow, etc. in the atmosphere have little effect on microwave propagation, which is that microwave energy penetrates these media and is basically unaffected, which lays a foundation for all-weather microwave communication and remote sensing technology. On the other hand, microwaves are the only electromagnetic waves (except light waves) that can penetrate the ionosphere and have penetrating properties. On the other hand, microwave energy penetrates organisms, and this microwave biomedicine lays the foundation.

Third, broadband characteristics. Any communication system must occupy a certain frequency band in order to transmit a certain amount. The bandwidth required to transmit a message. Because microwaves have wide frequency band characteristics, their information carrying capacity far exceeds medium wave, short wave, and ultrashort wave, so modern multi-channel wireless communication works almost in the microwave band.

Fourth, the thermal effect characteristics. When the electromagnetic energy of the microwave is transmitted to the inside of the dielectric body, the accelerated movement of the molecules inside the object to form an equilibrium state is that the molecules inside the object collide and rub against each other, and finally the object is heated, which is the thermal effect characteristic of the microwave.

Five, scattering characteristics. When an electromagnetic wave is incident on an object, scattering occurs in directions other than the incident wave direction. By detecting the scattering characteristics of different objects, the target feature information is extracted from it, and the target feature information is realized, thereby achieving target recognition, which is the basis for realizing research in the fields of microwave remote sensing and radar imaging.

Sixth, anti-low frequency interference characteristics. The noise around the earth is generally in the middle and low frequency regions, and the frequency components of the microwave band are quite different. Therefore, under the barrier of the microwave filter, they basically do not affect the normal communication, which is the anti-low frequency interference characteristic of the microwave.
