Microwave operation principle
This microwave source adopts continuous microwave magnetron as its microwave oscillation source. The continuous magnetron is a kind of cross-field microwave radio tube, the direct current field and the stationary magnetic field are vertical. The anode of the magnetron is a complex system of resonance.
The anode block consists of many little resonant cavity. Between them there is inductance coupling, so the anode block is the crossover network of microwave. The electron eradiated from the cathode of the magnetron will firstly be affected by the direct current field and curl like an angle.
While the electrons are moving from the cathode to the anode, the contrail of their movement is like a swing vibration. Under the condition of synchronism between high frequency field and electron cloud, the electron contrail will rise toward the anode direction and form electron spoke. Among the spoke, while the electrons are carrying through synchronistically, they will change the potential energy into high frequency energy and increase the high frequency breadth.
After the magnetron is started, the direct current which is instored in the resonance cavity will be changed into super-high frequency energy, finally, microwave source of enough power will exported through wave-guide.
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.
Microwave drying and sterilization features
1. Microwave drying sterilization drying time is short, strong fragrance products, uniform, bright color; has expanded by microwave drying effect on the subsequent smash much help.
2. Microwave is a direct function of the materials were, without intermediate conversion of other links which no additional heat loss, and the corresponding air furnace will not heat the container, so the high thermal efficiency, the production environment is significantly improved compared with the far-infrared heat Can save more than 30%.
3. Easy to control, advanced technology. Compared with the conventional method, which means that the use of equipment; no thermal inertia, operational flexibility; microwave power adjustable, the transmission speed is adjustable. In the microwave heating and drying, sterilization, no waste water, no gas and other produce, is a safe and sound tech.
4. Improve product quality, economic benefits. The working environment and equipment, low temperature, noise, greatly improved the working conditions, but also saves floor space, and easy removal.
5. Low-temperature sterilization to maintain nutrition and traditional flavor. Microwave sterilization is through to be special and nonthermal effects of heat sterilization, compared with the conventional heat sterilization can be at a relatively low temperature and shorter time to obtain the necessary disinfection and sterilization effect.
6. Practice shows that the sterilization temperature is generally 75 ~ 80 °C will be able to achieve the desired effect, in addition, microwave processing of food to retain more nutrients and color, smell, taste, shape and other flavors, and there is puffed effect. Such as conventional thermal processing of vegetables to retain the vitamin C is 46% to 50%, while the microwave treatment is 60% to 90%; conventional heating liver vitamin A retention was 58%, while the microwave heating is 84%.
