Main features of microwave heating
Rapid heating
Microwave heating and conventional heating methods are totally different.Microwave heating do not need the process of heat conduction,which make the material heated itself become a heating unit.Therefore,the materials of poorer heat conduction can also be to reach the heating temperature in a very short period. 
Symmetrical heating
Whichever the shape of each part of objects is, microwave heating is the object that make the electromagnetic waves infiltrating to the exterior and interior of the material heated symmetrically at the same time to produce heat energy. Because of no restrictions on the shape of material heated,there are materials that is even heating and no adust outside or unheated inside
Energy saving and efficient
The material containing water is easy to absorb microwave heat, therefore,there is no other heat loss besides a small amount of transmission loss.So higher thermal efficiency and more energy saving.which is heating energy-saving 1/3 over than the far-infrared heating
Mildewproof\sterilization\refreshing
Microwave heating with thermal and biological effects can sterilize and resist rot under lower temperatures. As the heating speed is faster and time is shorter,the microwave heating can reserve the activity and the vitamin in material heated furthest,and the original color and nutrients.
Advanced craftwork and easily controlled
As long as you control the microwave power, you can realize heat and termination immediately;Because of application of human-computer interface PLC.You can control heating process and heating norms automaticly through programming
Safety and innocuity
The microwave heating work in the heating-room and the waveguide pipe made of metal,which can prevent the liakage of the microwave,radioactivity harmful and discharge of harmful gas.There is no waste heat and dust pollution,so microwave heating neither contaminate food nor pollute the environment.
Principle of Microwave machine heating
Microwave frequency is electromagnetic waves of 300MHz-300GMHz. The water in medium materials heated is polar molecules, under the effect of the rapid change of electromagnetic field, its polarity orienration will alter with the changes of the external electric field with the high-speed, causing the movement and friction of molecule.So that the microwave field energy can be converted to heat energy in medium to rise the temperature of materials. Then materials heated go to produce heat, puffing and a series of physical and chemical processes, and so, microwave heating achieved.
Principle of Microwave machine sterilization
Microwave sterilization utilize the result of combined action of the thermal effects of and biological effects of electromagnetic fields.Microwave thermal effect on the bacterial is to make the protein of bacteria denatured,lost their nutrition, reproduction and survival conditions down to be dead. Microwave on the biological effects of the bacteria is that the microwave electric field changes cross-section of potential distribution of the bacterial cell membrane and impacts the concentration of  lon and electron around the membrane,which can change the permeability of cell membranes,therefore make bacteria innutrient not be mormal metabolism. The structure of bacterial disorders,and growth is inhibited bo de dead.Morover,nucleic acid genetic(RNA) and deoxyribose acid(DNA), which decide the normal growth and stability of bacterial,is curly-shaper macromolecule that made of a number of linked compactly hydrogen bond. The microwave can be strong enough to make hydrogen bond slack,ruptured and recombined,which include genetics to be multational, chromosme to be distortional or ever broken.
