The principle of microwave heating

Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .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.

Features and characteristics of microwave clove drying machine

1.save time ,fast

Microwave sterilization is microwave with food , bacteria, and microbial direct interaction, heating and non-thermal effect worked together to achieve rapid warming sterilization purpose, the processing time shortens greatly, the sterilization function of all kinds of material in commonly just need 3 to 5 minutes.

2.Low temperature sterilization keep nutrients and the traditional flavor

Microwave sterilization is through the special heat and non- hot effect,with low temperature and a relatively short period of time to obtain the sterilizing effect. General sterilization temperature in the 75 to 80 degrees Celsius, can achieve the result, moreover, microwave processing food can hold more nutrition composition and color, fragrance, taste, shape and flavor, has the expansion effect. Such as conventional thermal treatment of vegetables keep vitamin C are 46%- 50%, and is 60%- 90% microwave processing; Conventional heating pig liver vitamin A keep rate was 58%, and 84% for microwave heating.

3.Save energy

Microwave is directly on the food, and therefore had no extra thermal energy consumption . In contrast, general , electricity saving 30% -50%. Microwave energy as energy's utilization rate of 75%,Compare with far infrared and steam dry reduce energy consumption by 25% or more.

4. Even completely

Because microwave can through the whole food ,when process the food , the surface and inner can befuncted at the same time, so sterilizing uniform thoroughly.

5. Easy to control

The device can be used when open,no need waiting, which is not hot inertia, convenient operation, the microwave power can adjustable, transmission speed can be adjusted continuously from zero, it is easy to operate.

6. The equipment is simple, the craft is advanced

Microwave heating just have the basic conditions of water, electricity, as long as control power, can realize microwave heating or terminate immediately, use microwave equipment can process automation control of heating process and heating process specification.

7. Improve working conditions, and save cover area

Equipment working environment 's requirement is low, the noise is small, greatly improving working conditions, and a complete set of microwave equipment operation just 2-3 people
