The stove sterilization truth of the light wave: Sterilize and

The stove sterilization truth of the light wave: Sterilize and has not distinguished with the boiled water
First type H1N1 influenza begins to wreak havoc, " the light wave is sterilized " The concept has become hot. The light wave stove is on the occasion of 2003 while just putting out " SARS " ,Borrowed desinfecting concept fire once at that time. By 2009, sterilize the card and stage a comeback again. The light wave stove on the market, add two in the ordinary microwave oven " light wave is in charge of " ,The cost does not exceed 10.

Fig.: Whom some brand introduce can kill the intersection of light wave and the intersection of stove and the intersection of light wave and stove of bacterium, it is said permitted 100% desinfecting, than ordinary the intersection of microwave oven and several hundred at being expensive. In fact, it has just increased two halogenic lights to manage, sterilize and have no differences with the boiled water.

First type H1N1 influenza begins to wreak havoc, " the light wave is sterilized " The concept has become hot. The light wave stove is on the occasion of 2003 while just putting out " SARS " ,Borrowed desinfecting concept fire once at that time. By 2009, sterilize the card and stage a comeback again: " 100% sterilize and kill the poison, the instantaneous temperature can exceed 200 after starting the machine " , " light wave, microwave act on together, sterilize more completely. " Are these statements reasonable?

Kill the anthracia legend

According to the statements of the manufacturer, the light wave stove is the upgrading products of the microwave oven, except used for cooking, have still changed one's identity suddenly and sterilized and sterilized " The healthy bodyguard " . Every large microwave oven manufacturer begins " Do no decent work " ,Catch one's own one " The health card " . Glanz says their light wave stove 100% sterilizes, the beautiful ultraviolet ray microwave oven of the introduction original creation, "part ultraviolet ray, light wave ( Infrared ray) , the microwave is come to sterilize all over. "

In fact the light wave stove emerges and already puts on by oneself " Sterilize and sterilize " Veil. In 2001, Glanz began to first elect the light wave stove to U.S.A.. After being on the occasion of 9 11 incidents at that time, the shade of the terrorist attack of anthrax swept across the whole country, people do not dare to touch mail and parcel mailed. Against the terrific expert of biochemistry Aly and Bick (KenAlibek) Advise people to use the microwave oven or vapour electric iron to kill the anthracia spore. In the a lot of families in U.S.A., the microwave oven is not rare as sterilizing tools. This essence of sterilizing the course, it is to raise the temperature to make the bacterium extremely hot.

When the light wave stove is listed, the trade company starts another sales tactics. Only cook the function and can't already form a brand-new market concept. The light wave stove is not merely a upgrading edition of the microwave oven, but with " completely more desinfecting " Concept smoothly lay American market. Then has the disinfective action of the light wave stove been really upgraded?

Extremely hot germ

The light wave stove is actually very simple, but the microwave oven adds the oven. Said light wave stove on the market, the majority is that " the microwave of light wave makes the stove up " ,That is to say that adds two in the ordinary microwave oven " The light wave is in charge of " Burn the germ to death with the high temperature, the cost does not exceed 10 yuan.

This " light wave tube " Names formal in charge ofing,fill by gas (iodine or bromine generally)s halogenic with each Light in charge of,like ordinary incandescent lamp bulb,Yes let's emit on visible light sum infrared ray. But temperature and luminance that halogen is in charge of are higher, because halogen in the light tube can prevent the evaporation of the filament from lossing. The general bulb will turn black when using long, this is because tungsten of the filament is evaporated and condensed on the glass shell of bulb, but halogen in the halogenic tube can combine and form tungsten halide with tungsten steam ' Tungsten or bromine tungsten) iodination ,Get back to the filament again, is heated and resolved into halogenic vapour and tungsten, remedy the part that the filament is evaporated off. The regenerated course of this cycle, make the life-span that halogen is in charge of 4 times longer than the general bulb, the structure is still relatively simple. When halogen is in charge of to begin to give out light, the infrared ray emitted will heat the food. This course approaches the roasting of the oven even more.

Then how on earth is halogen of the light wave stove in charge of killing virus to sterilize the function? The trade company provides such explanation:

"Studies have suggested, the bacterium, adult are like any biological cell, it is a kind of agglomeration attitude medium formed by complicated compounds such as water, protein, nuclear acid, carbohydrate, fat and inorganic matter,etc.. Among them water is principal ingredients of biological cells, various physiological activities of the bacterium must have participation of water to go on, and breed the course in growth of bacterium, the absorption of various nutrients is finished by diffusion, infiltration and adsorption of the cell membrane quality. The microwave oven of light wave is made up through light wave and microwave, under the function of the microwave field of certain intensity, make the molecules of different worms and body of fungus can intensify to absorb the microwave of light wave at the same time. Because they to condense the intersection of attitude and material, effort among the molecule can aggravate microwave, can be transformed to the energy state of heat energy by light wave, function that make inner protein of bacterium's body have no hot movement of polarity at the same time and the polarity rotates two respects, the structure of its space changes or is destroyed and lost the living beings actively, lead to the fact the bacterium dies finally. "

Very strong scientific and technological sense? In fact this passage speaks a thing: The germ is that a quilt is extremely hot. Actually the germ has no difference with scalding very much with the boiled water in the course of this. " the microwave Yes, light wave can be transformed to the energy state of heat energy " That is to say microwave and light wave are all used for heating; " there are not hot movement of polarity and polarity that are rotated " That is to say hot essence is a molecular motion; And " the space structure changes or is destroyed " ,It is the egg that boils the hard simple reason like this of becoming. The germ to be killed outside the human body is actually very easy, heating, alcohol, the sun ultraviolet ray will all do, as for virus being more fragile, can kill in several minutes when heating to above 70 .

So even if light wave stove have disinfecting efficiency really, and general hot water, steam produce same result only too. In addition, it does not mean totally resting assured either to use the light wave stove to heat and sterilize. Because the light wave stove relies mainly on heating the food usually, the residual food causes germs more easily on the oven, if does not wash before using, will cause the secondary pollution instead probably.

Tips: The light wave stove can mean three kinds of different electrical home appliances

1. The microwave of light wave combines the stove

English name: Convectionmicrowaveoven

Operation principle: Add the function of the convection type oven on the ordinary microwave oven, but microwave ovens analyzed in this text. This is the most common light wave stove on the market too.

Misunderstand commonly: The light wave stove can keep more nutrition in food.

Answer: It is certain to destroy nutrition if heat. Compare, the microwave heats the penetrating type to water in the food, heat is more even; But the light wave is from outside to inside " Bake " Food. The light wave function is apter instead to burn the food, cause nutrition to run off. And halogen of this kind of light wave stove is in charge of the power too lightly, it is very difficult to finish roasting and cooking.

2. Desk-top light wave stove

English name: Glass-ceramiccooktop

Operation principle: It is also called the a little brilliant glass stove, uses halogen to be in charge of producing heat too. The infrared ray produced through reflecting light on the board and in charge of halogen gathers, see through the heat-resisting a little brilliant glass panel, conduct heat energy to a pot of bottom to achieve the goal of cooking the food. It looks like the electromagnetism stove, it is in fact the old products with a history of more than 30 years.

Misunderstand commonly: The desk-top light wave stove " There is no radiation in environmental protection " .

Answer: In fact the light wave stove uses the infrared ray to heat. The infrared ray is an electromagnetic wave too, so the desk-top light wave stove will produce radiation too. Moreover, the wavelength of the infrared ray is shorter than the radiowave of the microwave oven, according to the quantum mechanics principle, the greater the photon energy of the shorter wavelength is. If there is danger in radiation, infrared rays are more dangerous than the microwave.

3. Convection type oven

English name: Convectionoven

Operation principle: It is the improvement edition of the oven. The oven uses the red copper heated to be in charge of, produce the infrared ray and roast bread, meat and Pizza, will produce in the part overheatedly sometimes, bake the outstanding position of the food burntly; And the convection type oven increases a convection fan, let the food be heated evenly, efficiency is a little higher than the ordinary oven. The small-scale convection type oven of the family expenses uses halogen to be in charge of too, can be competent at real roasting to cook.

Misunderstand commonly: Convection type 60% of energy-conservation of oven.

Answer: Its really than the oven energy-conservation, but can not compare with the microwave oven, because the microwave oven needn't heat the container, transmit heat on the food directly. (The source of this text: New authors of ceremonies: Zhou MingJie)
