The working principle of the microwave dryer is mainly to use the penetrating heating of microwaves to increase the temperature of the material, so that the water in the material vaporizes and evaporates, thereby achieving the purpose of drying. Specifically, microwaves are a kind of electromagnetic wave with penetrating, refractive and wave-absorbing properties. When microwaves act on the material, polar molecules such as water molecules in the material will absorb microwave energy and generate high-frequency friction under the action of microwaves to generate heat. This heat causes the water temperature in the material to rise and vaporize, and then the evaporated water vapor is discharged through the dehumidification system, thereby achieving the drying of the material.

In addition, the microwave dryer also has the following characteristics:

1. Fast drying speed and high efficiency: Since microwaves can directly act on the water molecules inside the material, the drying speed is very fast and the efficiency is also very high.

2. Environmental protection and energy saving: The microwave dryer does not need to burn fossil fuels, so it does not produce harmful gases and pollutants. It is an environmentally friendly drying method. At the same time, since the energy consumption of microwave heating is low, it also has the advantage of energy saving.

3. The material is heated evenly: Microwaves can penetrate the material evenly, so that the water molecules inside the material are heated at the same time, so the material is heated evenly, and it is not easy to have problems such as burning or uneven drying.

However, microwave dryers also have some disadvantages, such as complex equipment, expensive price, and high unit energy consumption. In addition, since microwaves are selective in heating materials, different materials have different absorption capacities for microwaves, so in practical applications, they need to be adjusted and optimized according to the characteristics of the materials.

In general, the working principle of a microwave dryer is to use the penetrating heating of microwaves to increase the temperature of the material, so that the moisture in the material vaporizes and evaporates, thereby achieving the purpose of drying. It has the advantages of fast drying speed, high efficiency, environmental protection and energy saving, but there are also some disadvantages that need to be paid attention to in practical applications.
