Microwave dryer

The purpose of microwave dryer is:

Mainly used for paste food, powder food, granular food, agricultural products, and other products that need to be dried by microwave drying sterilization; microwave dryer can be designed and manufactured according to the different needs of different products.


Heating principle of microwave dryer


Microwave refers to electromagnetic waves with frequencies ranging from 300 MHz to 300000 trillion Hz. The water molecules in the heated medium are polar molecules. Under the fast changing high frequency electromagnetic field, its polar orientation will change with the change of external electric field, resulting in the movement of molecules and mutual friction effect. At this time, the field energy of microwave field can be transformed into heat energy in the medium, which makes the material temperature rise, and produces a series of physical and chemical processes, such as heating and expansion, to achieve the purpose of microwave heating and drying.

The characteristics of microwave dryer are as follows:

Microwave drying is an efficient, energy saving, stable, reliable, simple device, easy to operate and new technology. Microwave dryer is characterized by continuous production of equipment, only need electricity, no need for other energy, can quickly dry materials, equipment occupies a small area, pollution-free, simple operation; no need for preheating and no energy loss after shutdown. Less manpower and high product quality. The equipment is highly evolved. It is a new and high technology product which can not be replaced by other devices.
