30KW carton box paper board microwave dryer

What is Microwave?

Microwave is the frequency of 300 MHZ ~ 300 GHZ electromagnetic wave, it is short radio waves in a limited frequency band, the wavelength between 1 mm ~ 1 m electromagnetic wave, it is generally referred to as the decimeter wave, centimeter wave and millimeter wave. Microwave frequency is higher than general radio frequency, often also referred to as "ultra high frequency electromagnetic wave. As a kind of electromagnetic wave of microwave also have wave-particle duality. Basic properties of microwave usually appears as transmission, reflection and absorption three characteristics. For glass, plastic and porcelain, microwave is almost through without being absorbed. For water and food, etc. will absorb microwave and heating by itself. For metal stuff, it will bounce back the microwave.

Microwave drying principle:

Microwave drying is a new type of drying method. When drying, microwave converted into heat enerLD that can be applied directly to medium, because the microwave has penetrating performance inside and outside the media, heating at the same time, do not need to heat conduction, so very fast heating, the water content below 30% of food, can shorten the drying speed hundreds of times. Regardless of any shape objects, because the object of dielectric heating at the same time, both inside and outside material of inside and outside temperature difference is small, uniform heating, the drying quality greatly improved.

Advantage of the microwave dryer for the carton paper board:

1, Fast drying.

2, Suitable for thick paper board, because of microwave panatric friction heating principle.

3, Auto running.

4, No air pollution, suitable for where seriouse on the environment protection.
