Microwave drying equipment It is a device that uses 915MHZ or 2450MHZ frequency electromagnetic waves to heat materials. Because of the control of microwave frequency band, 2450MHZ (equivalent to the frequency of household microwave oven), 915MHZ and 433MHZ are commonly used in the field of microwave heating in China, especially 2450MHZ microwave.
When purchasing microwave drying equipment, you should first understand the basic principles of microwave heating.
1.1 Principle of microwave heating: microwave heating uses high-frequency oscillations of polar molecules in the microwave field and molecular friction to generate heat, so the prerequisite must be polar molecules. Non polar molecules and covalent molecules are not heated by microwave, and water itself is a polar molecule, which is the main reason why microwave is used to dry water. Of course, besides water, other materials are easy to be heated by microwave, such as carbon materials, silicon materials, metal oxides, etc.
1.2. The relationship between frequency band and heating. The frequency of microwave represents the frequency of electromagnetic field oscillation. The higher the frequency, the faster the oscillation is, and the faster the heating speed is. Therefore, the microwave heating speed of 2450MHZ frequency is fast, so is the efficiency of 915MHZ and 433MHZ frequency low? Of course not. In addition to the frequency, microwave has an important parameter that is wavelength. The higher the frequency is, the shorter the wavelength is, the lower the frequency is, and the longer the wavelength is, the frequency determines the oscillation rate, and the wavelength determines the penetration depth, so what materials are heated, The frequency of microwave to be used depends on the actual situation, and the one suitable for it is good.
