The principle of microwave heating
Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .
It can penetrate the inside of the material.atht is to say microwave energy can heat the matrial from insedeto outside at the same time.
The water molecule in medium materials is polar molecule,under the effect of the rapid change of
electromagnetic field,its polarity orientation 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 mudium to rise the temperature of materials.
accomplishing heating ,puffing and a series of physical and chemical processes ,
and so ,mircrowave heating is achieved.
The principle of microwave sterilizing
Mircowave sterilizing is the result of combined action of the thermal effect of eletromgnetic fields and the biological
effect.Thermal effect of microwave on the bacteria denatures the protein of bacteria ,
and make the bacteria lost the condition of nutrition,reproduction and survival so as to die .
The biological effects of microwave on the bacteria is that the microwave electric field changes the potential
distribution of cross
section of the bacterial cell membrane and impacts the concentration of electron and lon around the membrane ,
and changes the permeability of cell membranes ,therefore the bacterium become innutrient and lost normal
metabolism.The structure and function of bacterium fall into disorder ,and theirs growth are inhibited ,
as a result they are dead.Moreover ,nucleic acid genetic(RNA) and deoxyribose acid (DNA),which decide the normal growth and stability of bacterial,are curly-shaped macromolecule made of a number of linked compactly hydrongen bond .
The microwave can be strong enough to make hydrogen bond stack ,rupture and recombine ,
and induce intragenic mutation or chromosome aberration and even rupure.
