Product description
Description of microwave drying and sterilization equipment
1. Microwave drying equipment, microwave rapid dehydration technology using energy-efficient, will extract on the coneyor belt to scrape a thin layer, quicklt though the microwave heating chamber, low teperature drying of material composition, taste, color is not changed.
2. Microwave frequency is electromagnetic waves of 300 MHz -300 GHz. The water in medium materialsheated 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 ofmolecule. 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.
3. Microwave sterilization utilize the result of combined action of the thermal effects of and biological effects of electromagnetic fields.
4. 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.
5. 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 nutrient not be normal metabolism. The structure of bacterial disorders, and growth is inhibited to be dead.
6. 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.

Feature of microwave drying and sterilization equipment
1. 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.
2. No matter what 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.Beacause of no restrictions on the shape of material heated, there are materials that is even heating and no adust outside or unheated inside.
3.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.
4. 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.
5.The microwave heating work in the heating-room and the waveguide pipe made of metal ,which can prevent the leakage 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.
6. 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.

FAQ
Microwave equipment is how to prevent microwave leakage problem?
According to the International Elctrotechnical Commission(IEC) standard, microwave leakage should be less than 5 mW/cm2, domestic standards follow the IECstanard, and the American UL standard limit is 1 mW/cm2. Shangdong Kehonh microwave energy limited the amount of leakage of microwave equipment under the control of the micro Watt level, in line with American Standard, please rest assured that use.
The leak site of microwave equipment for general observation door and a discharging port(tunnel equipment), using the general observation door with choke microwave shielding door, mainly to ensure that all smooth Kehonh microwave equipment microwave cavity door observation door with reinforced frame, which closely observe the door, prevent micro-blong leakage. Inlet and outlet suppressor by microwave reflector, reflector, absorbing wave material composition, each process strictly in accordance with the requipments of complete, leak detection equipment for leak testing anti microwave strict with advanced microwave factory, fully ensure the microwave leakage within the specified value. In addition discharging tunnel type microwave equipment mouth height effect on microwave leakage, the greater the opening height corresponding to the length of the microwave suppressor, the overall length of the equipment is extended accordingly.
