Lightwave technology combines microwave sterilization applications
1, What is light sterilization ?
Lightwave microwave sterilization sterilization function is actually an innovative enhanced and improved. Light microwave microwave oven is generally more than the upper chamber to set a light generator , both in the use of microwave operation , and light can be heated alone , combination microwave heating can be light . When a combination of microwave heating with light , the light source and the magnetron can be started simultaneously , light emitted from the light focused by the light reflected by the reflector , light and microwave integrated both of 300,000 km / sec rate of a closed furnace chamber at a height of foods from inside to outside , from outside to inside the high-speed cross- heating , so as to achieve a better more thorough rapid bactericidal effect .
2, the oven can really disinfect it ? What is the principle ?
Experts believe that with the microwave oven also has powerful sterilization function , but is also an enhanced microwave . Bacteria generally are killed at high temperature . A microwave absorbability , pyrogenicity , transmittable , when the microwave encounters polar molecules ( such as water molecules in bacterial cells ) will cause the oscillation of the molecular molecular intense heat ( temperature rise rapidly up to 120 ℃, substantially equivalent to high-pressure steam sterilization temperature ) , the microwave energy into heat energy to kill bacteria .
The oven is heated in a microwave oven magnetron original principle, rely on additional special light generator quickly produce a wide wavelength light and heat energy to heat . Studies have shown that bacteria , adults with any biological cells, is composed of water , proteins , nucleic acids, carbohydrates , fats , and inorganic compounds such as complex consisting of a condensed medium . Wherein the water is the main component of biological cells , bacteria, various physiological activities must be carried out in water , and the bacterial growth and reproduction process , a variety of the absorption of nutrients through the cell mass diffusion , penetration and adsorption to complete the . Light microwave and microwave combination through the light at a certain intensity of the microwave field under the action of a variety of insects and bacteria molecules absorb light while microwave energy to heat up. Because they are condensed matter , intermolecular forces exacerbated the microwave energy , light energy converted to heat energy state , so that the protein in bacteria by both polar and non-polar thermal motion of rotating two effects , the spatial structure changes destruction or loss of biological activity , causing bacteria eventually die.
3 , oven sterilization function scientifically validated do ?
There . Many countries around the world have tried for many germs and disinfect the test , concluding that the state 1-6 minutes in the microwave almost all bacteria are not live , in the light of microwave state is more effective. Here are a few examples.
Japan's climate is humid , moldy food preservation is a major problem, sponge cake with 5-10KW microwave irradiation for 2 minutes, temperature rose to 70 ℃, 15 days does not moldy , instead of the microwave treatment within 5 days that moldy .
Professor of the Japanese Red Star Bacillus subtilis, E. coli, Penicillium , Aspergillus and other microorganisms on the respective medium. Then microwave 2800MHz, pulse width 1μs, pulse repetition frequency 2000Hz , power 2KW, irradiation can kill 90 seconds . And the same with boiling water 15 minutes Bacillus subtilis to kill .
1965 Austrian music Mori bread mold with a 2450MHz microwave radiation , heat radiation at 65 ℃ for 5-10 minutes , 21 days continued to show a fresh state. It is believed that such mold Penicillium and Aspergillus spores lethal temperature is 68-71 ℃, but the microwave did not reach this temperature , mold still killed. Analysis: One possibility is to heat radiation in the bread during the bread has not yet heated , the mold body of salt solutions may select the microwave absorbing large, so the temperature may be higher than the bread fungus body temperature and death. Another possibility is that the role of non-thermal effects of microwave allow bacteria to death.
In our country there are a lot of use of microwave disinfection experimental study . Such as bills disinfection, sterilization of food , feed disinfection, soy and milk disinfection, pest control and other trees .
According to the Guangdong Provincial Health and Epidemic Prevention Center test report , Galanz digital oven right foods have significant bactericidal effect: artificially contaminated milk samples of Staphylococcus aureus and Escherichia coli artificially contaminated water samples , heating 3.5 minutes sterilization rate of 100% ; pair of raw pork , raw fish , raw milk and tap water samples naturally contaminated bacteria, heating 3.5 minutes and 10 minutes , the sterilization rate of 100% ; for pork and fish samples artificially contaminated Salmonella, heated for 10 minutes sterilization rate of 100% .
4 , microwave and oven bactericidal effects okay ?
Microwave and oven with superior bactericidal effect , especially the combination of light and microwave , a dual bactericidal function more efficiently.
Take an example left- heating leftovers . Refrigerator energy for food preservation, but it is not safe , the food in the refrigerator , some bacteria such as Escherichia coli , Staphylococcus aureus , etc. but also in which tenaciously survive. Microwave in 1-2 minutes to destroy all the bacteria . The determination of epidemic prevention station , with a 500W microwave oven containing 1923 / g E. coli sausage processing, 30 seconds remaining 260 / g after 60 seconds kill all the same with 1923 / g E. coli smoked fish for processing, after 30 seconds only survived 13 / g after 60 seconds kill all .
Microwave and oven increasingly become a trusted disinfection appliances, foreign and even has a refrigerator, microwave accessory products .
5, with oven disinfected thoroughly to kill bacteria do ? Compared with the ordinary disinfection methods What are the advantages it ?
There a way to kill bacteria is absolutely 100% complete . But compared to other disinfection methods such as hot water , steam , ultraviolet infrared, additives , oven with a more powerful bactericidal effect , the biggest advantage is clean and fast , is the most ideal method of sterilizing a .
According to Peking University First Hospital microbiological experts, currently on the market can achieve sterilization There are basically two types of home appliances , home appliances using one kind of disinfectant, relying on chemical disinfectants to achieve sterilization purposes , this is very dangerous, because disinfectants abuse resistance will produce serious consequences on the human body great harm . Another is oven , microwave , etc., as a physical disinfection methods , they seem safer and more hygienic.
6, the oven has bactericidal effect in addition to the food , what else can be disinfected everyday objects ?
Digital Lightwave use high-temperature microwave heating function , but also in a very short period of time to eliminate cutlery, cups , towels , napkins , masks , gloves , clothing and other household goods on viruses and bacteria , in addition to the scientific method can also be used for usually have the most contact banknotes were disinfected.
7 , how to use everyday objects oven for disinfection ?
Every morning after the individual towels and cups etc. with a microwave oven for heat sterilization , disinfection Alternatively, you can look utensils. Cups and cutlery in disinfection should pay attention to the microwave disinfection can not choose metal containers , including inlaid in Phnom Penh, silver side dishes , you can use glass, ceramic , heat-resistant plastic and glass ceramics and other non-metallic containers . This is because the metal microwave transmission is bad, microwave loss itself is large and will reflect the microwave , and even sparking phenomenon, affecting work efficiency microwave oven for sterilization will have hindered . But the oven on the contrary , you can use metal utensils . For non-metallic utensils , microwave and lightwave combining the functions better.
Need to wear a mask when going out , you should first before using masks wet , place in microwave or oven sterilized within 2-3 minutes. A use of masks for 4 hours, so a mask of day for the best timing for heat sterilization .
Usually wash your hands when not combined with others towel to wipe , preferably with a towel for personal use , and should be regularly carried out on a towel or light microwave disinfection ; every day before going to sleep can be a cup , utensils , etc. and then disinfected to prevent bacteria breeding.
Most contact with the clothes on weekdays , notes , etc. can be disinfected. Paper products heated in the oven cavity is best to put a glass of water at the same time or directly with the appropriate books or wet towel to wrap banknotes , and strictly control the heating time , prevent paper browned ; right clothing and disinfection should be sprinkled some water on clothes , to improve the disinfection of clothing and prevent burning.
