Microwave heating characteristics
    1 heating uniformity, rapid
The heating method is commonly used by the heat radiation and conduction , so that the surface of the object within the first heat and then spread . The microwave energy is directly penetrate inside the object , in addition to large or extra-thick objects can be both inside and outside the outer heating , greatly reducing the heating time. Therefore, the application of microwave heating and drying items can significantly increase productivity, improve product quality.
    2 selective heating
Because the microwave absorption materials are different , it is the greater the loss tangent tanD , the greater the ability to absorb microwaves . TanD various materials in the range of 01001 - 015 , the absorption capacity of the microwave are quite different, which makes the microwave heating of substances having a selectivity. For example, microwave drying of paper , because water can quickly absorb microwave energy , microwave energy absorbed by the wet paper and more, and microwave properties of dry paper more backward , so that the dry part of the absorption of microwave energy is small, so that the paper be uniform drying .
    3 Control timely
Most conventional heating systems, will take a long time to reach the desired temperature . The use of microwave heating , a few minutes to the normal operation of the power to adjust the microwave output power, heating the material to change the situation immediately without inert , facilitate automatic control and continuous production.
    4 . Reduce heating equipment size
Microwave heating in a short time because the energy can be transferred to the object , so the productivity of a given , it can greatly reduce the heating apparatus. Because it is the medium itself heat, so the microwave radiation device itself does not heat, which avoids the environmental temperature, improve the working environment .
    5 thermal efficiency
Microwave heating can achieve high efficiency. Currently , microwave systems to convert alternating current of 50 Hz the thermal material , typically about 50% efficiency , with the efficiency of microwave tube will further increase the efficiency of the microwave heating .
