The microwave dryer is more and more popular nowadays. Microwave energy is converted into direct effects on heat. Microwave has penetrating performance inside and outside the media heating at the same time. Microwave can save drying time and avoid the raw material becoming metamorphism or coking the overheat environment, The drying effect is good for seafood, tea, mushroom, and so on.
What is the advantage of the microwave dryer?
1.Easily control
The whole machine adopts modular design and controlled by PLC system, easy operation.
2.Short processing time
Because the microwave has the penetrating property to heat the inside and outside of the material at the same time, no heat transfer medium, so the heating speed is very fast. Typically it will dry materials in one-tenth the time of the standard dryers.
3.Improve final product quality and extend its shelf-life
Microwave has the effect of disinfection and sterilization to keep product safety and extend its shelf-life.
4.Energy savings
The aqueous material easily absorbs microwaves and generates heat, so there is almost no heat loss in the heating process ensure heating efficiency and energy saving.
5.Uniform heating
The hot air in regular food dehydrators dries foods from the outside. This causes the surface to harden, making it difficult for the water inside to get out and lengthening the drying process. In contrast, the microwave drying machine uses microwaves that reach inside the food, causing the water in it to evaporate. The water vapor is carried away in air currents. This technique results in uniform drying and allows the process to be completed more quickly.
6. Control temperature accurately
The equipment is equipped with the imported infrared thermometer to control temperature accurately, automatically achieve the microwave power adjustment of various materials to meet the microwave energy reach the material inside. The temperature fluctuation range is ≤ 3 °C.
7.Environmental friendly
Microwave drying equipment does not produce "three wastes", because microwave energy is controlled in the heating chamber. There are no radioactive hazards and harmful gas emissions, no residual heat and dust pollution, environmentally friendly.
