10 facts and myths about the microwave




1. Myth: The explosion of iron plates stubbornly held assertion that the iron plate can trigger an explosion of great power (in fact, in the worst case, it will cause damage to the magnetron due to sparking). Microwave radiation can not penetrate the metal objects, so it is impossible to prepare food in a metal bowl. Metal utensils and metal instruments (spoons, forks), located in the furnace during the heating process, it can withdraw from the system. 2. Myth: the German, the military origin of the microwave first microwave oven, called «Radiomissor», was allegedly developed by German scientists during World War II, she even allegedly used in the current German army, to heat food, but turned out to be unsafe, and to give it up (Russian sites with the link to foreign and foreign - in the Russian research allegedly nonexistent conducted in the Russian cities of Rajasthan and Kinski). 3. Myth: microwave leads to the loss of nutrients in fact any cooking process results in the loss of nutrients and vitamins. Microwave merely heats the food, with the result that there is a loss (decomposition evaporation, etc.) portion substances. 4. Myth: The myth about allergies allergies is: Microwave can cause allergies ... to electromagnetic waves. 5. Myth: microwave radioactive Microwaves are not radioactive. They, as well as the sun and the fire just heated food. Furnaces emit microwaves which cause friction of the water molecules (dipole shear), resulting in heating. 6. Myth: heating food in the microwave takes place inside There is a widespread belief that a microwave oven heats food from the "inside out." In fact, the microwaves go outside to the inside, trapped in the outer layers of the food because warming evenly moist product takes approximately the same as in the ovens (To see this, it is enough to warm boiled potatoes "in uniform", where the thin rind is sufficient protection product from drying out). Misperception because the microwaves do not affect the dry non-conductive materials, which are usually on the surface of foods, and therefore the heating in some cases starts deeper than with other methods of heating (bakery products, for example, are heated is from the "inside", and It is for this reason - the bread and rolls from the outside has dried up crust, and most of the moisture is concentrated inside). 7. Fact: can not be heated in a microwave egg can not be heated in microwave ovens fluid in sealed containers and whole birds' eggs - because of the strong evaporation of water inside them creates high pressure and, consequently, they may explode. For the same reason desirable to warm up much sausage products covered with plastic wrap. 8. Fact: The water in the microwave can overheat warming up in the microwave water should be careful - the water is able to overheat, that is, to heating above the boiling point. The superheated liquid is able to boil almost instantly by a careless movement. This applies not only distilled water but also to any water that contains few suspended particles. The more smooth and uniform inner surface of a vessel with water, the higher the risk. If the narrow neck of the vessel, then it is likely that at the beginning of the boil superheated water will pour out and will burn your hands. 9. Fact: The invention was an accident microwave engineer Percy Spencer American first noticed the ability of microwave radiation to heat products and patented microwave. At the time of the invention, Spencer worked for Raytheon, engaged in manufacturing equipment for radars. According to legend, when he experimented with another magnetron, Spencer noticed that a piece of chocolate in his pocket melted. Stranger Than Fiction: True Stories is that while he would have received a fatal defeat from the microwave, although the wrapper foil can be heated much stronger and the body, and chocolates, and significantly change the temperature before the damage occurred to the body. According to another version, he noticed that the sandwich is hot, put on the included magnetron. Perhaps the reason for the invention was just a burn, but for commercial reasons to spoil the image of the device was impractical. 10. Fact: In the USSR issued a microwave in the USSR from the mid 80s microwaves produced by the plant ZIL (model "ZIL") and Pivdenmash (models "Mriya MB", "Dnepryanka-1" (1990, 32 liters, power 2300 Watt, weight 40 kg, the price of 350 rubles.), "Dnepryanka-2"), but they were used in imported magnetrons Japan.
