Brief introduction of microwave heating principle
Microwave is a very short wavelength electromagnetic wave, which belongs a electromagnetic wave like radio waves, infrared, visible light and ultraviolet light .Its frequency range from 300MHz to 300kMHz, that is, the wavelength from 1 meter to 1 mm range.
The principle of microwave heating: microwave heating is to use microwave as a kind of energy,using of microwave field to achieve the material's own heating; Under the action of microwave field, material molecules produce polarization, orientation, friction and collision, absorb microwave energy and turn microwave energy into heat energy to raise their own temperature. Microwave heating means that the object heats itself after absorbing microwave, and the heating is carried out from the inside and outside of the object at the same time.
Microwave heating features:
☆ Rapid heating: Microwave energy spreads in the object at approximately the speed of light (3×1010cm/s), and the microwave energy can be converted into the heat energy of the object instantaneously (about 10-9 seconds), without the heat conduction process.
☆ Fast response ability: can quickly start, stop and adjust the output microwave power, simple operation.
☆ Uniform heating: both inside and outside heating, the overall temperature of the object is uniform.
☆ Selective heating: The medium loss is larger, the absorption of microwave energy is more, the temperature rises higher, and the heating is faster; Vice versa.
☆ High heating efficiency: Because the heated object absorbs microwave heating itself, there is no heat conduction process, no heating environment, almost no heat loss.
☆ Simple to use and operate, hardly affect the ambient temperature, improve working conditions.
