1, fast heating conventional heating such as flame, hot air, electric, steam, etc., are using the principle of heat transfer heat from the heated object external incoming internal and gradually make the object center temperature, called the external heating. To achieve the required temperature of the center, take some time, poor thermal conductivity of objects required for even longer. Microwave heating is to heat the heated material itself becomes the body, called the internal heating, no heat transfer process, both inside and outside heat, so they can achieve in a short time the heating effect. 
 2, uniform heating conventional heating, in order to improve the heating rate, we need to increase the heating temperature, prone to endogenous phenomenon outside the focus. Microwave heating, the object can usually evenly penetrate all parts of the electromagnetic waves to produce heat, so even greatly improved. 
 3, energy efficient heating in the microwave, the microwave energy absorbed by the object can be heated and heat, heated indoor air and the corresponding containers are not heat, so the high thermal efficiency, improved production environment. 
 4, easy to control microwave heating of small thermal inertia. If equipped with computer control, is particularly suitable for heating the heating process automation. 
 5, low temperature sterilization, pollution-free microwave energy itself is not food contamination, thermal effects of microwave sterilization and can double in a lower temperature to kill bacteria, which can provide a more nutritious food to maintain the pasteurization method. 
 6, selective microwave heating properties of different materials have different functions, which is beneficial to the drying operation. Because water molecules absorb the microwave best, so the high water content of the site, low moisture absorption of microwave power over the site of which is to choose the heating characteristics. Drying wood, paper and other products, the use of this feature can be uniformly heated and evenly dry. It is noteworthy that some of the material when the temperature is higher, the better absorption, resulting in a vicious cycle, resulting in a partial rapid temperature rise is too dry, or even charring, microwave heating of such material when heated to pay attention to the development of rational processes. 
 7, safe and sound in the microwave heating, drying, no waste water, waste, and there are no remnants of radiation, the microwave leakage is significantly lower than the state to ensure the development of safety standards, is a very safe and harmless high-tech technology.
