The principle of microwave heating

Microwave frequency is electromagnetic waves of 300 MHz -300 GHz. The water in medium materials heated is polar molecules, 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 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 bacteria 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 Ion and electron around
the membrane, which can change the permeability of cell membranes,therefore
make bacteria innutrient not be normal
metabolism. The structure of bacterial disorders, and growth is inhibited to be
dead. Moreover, nucleic acid genetic (RNA) and deoxyribose acid (DNA),which
decide the normal growth and stability of bacterial,is curly-shaped 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 induce genetics to be
mutational,chromosome to be distortional
or even broken.
