First, the microwave heating actual heatable materials are:

1. Food heating. Fermentation, mildewproof, bactericidal, dry, (vegetables, tea, eggs, meat, pasta, etc.), cooked in a microwave oven (steamed, boiled). Thaw and so on.
2. Grain processing. Exterminating and drying.
3. Rubber and plastics industry. Sulfur, foaming, injection molding.
4, leather. Drying and setting processing.
5. Paper and textiles. Dry and dye.
6, wood. Dry, bond, bend.
7, medical. Hyperthermia of cancerous tumors, dehydration and drying of experimental animals.
8. Metallurgical engineering. The steelmaking furnace and the mold are dry.
9, glass. Building foundation rock formations, concrete blocks, etc.
10. Melting. Glass industry and nuclear industry waste.                               
11. Maintenance of asphalt pavement.

What are the advantages of microwave heating compared to conventional heating methods:
1, not only by heat conduction heating, can go deep into the object to heat in a very short time.
2, microwave heating efficiency is high, the traditional heating is from the outside to the inside, and the heating space is wide, consumes inefficient heat energy, so that the thermal efficiency is reduced and the microwave heating penetrates into the deep part of the object, generating heat, heat loss is very small, microwave power conversion The efficiency of heat is up to 80%.
3. Even complex object shapes can be heated evenly.
4, according to different object characteristics can be heated by the selection method.
5. The heating power (ie heating) can be easily controlled.
6, easy to operate.
7. It can be heated in a completely sealed container, or even in a vacuum container or a closed container with other protective gas.
8. Create a good heating environment, such as not generating hot air and noise or discharging harmful gases to form a clean working environment.

    Microwave heating has the advantages of high efficiency and rapid heating; however, if the optimal heating process can be selected, the heating time can be reduced by 70%-80%, and the heating device footprint can be reduced by 1/10-1/5.
    It should also be noted that the microwave heating is not omnipotent. It is necessary to truly understand the microwave characteristics. For example, for a large volume, the heat conduction performance is poor, and when the deep part is not easily heated, it is most desirable to use microwave heating.
    Conversely, for thinner objects, there is no difference between general external heating and microwave heating, but the economy may be different. An example of the use of microwave heating will be described below in conjunction with the following chapters.
