How does the microwave oven work and how it was invented?

The last century is a century of discoveries andinnovations. It was invented a lot of devices that today firmly entered our life. And one of such inventions is a microwave oven. A completely new approach to the preparation of tasty and healthy food. But how does it work? Strangely enough, but the appearance of the furnace is due to the war industry. It was in radar for the first time that they began using superhigh frequencies to identify targets. In the early 1930s, in one US laboratory, the staff accidentally cooked the first dish with a microwave generator. This dish turned out to be sausages. This is the first mention of the microwave cooking method. And today italy riemini 3 star hotels in which are popular, just awash with microwave ovens from different manufacturers.

And in 1945 the microwave was patented,it really had a completely different look, not quite like the one we used to see. These were huge closets, the heart of which was a magnetron - a special radio lamp that emits waves in the microwave range. Here is a story, if briefly. In fact, the invention of microwave is the work of thousands of scientists. Today, all ovens operate at a dedicated frequency of 2450 Mega Hertz. According to international agreements, the stoves of all manufacturers should work at this frequency, so as not to interfere with radar stations. The basis of any stove is a magnetron, its voltage is about 4 thousand volts. The mains voltage is small, therefore an increase is required, which is due to the use of special transformers. Magnetron, which has a power of 850 watts, necessarily has a radiator and a fan, which when turned on and blows the device.

Radiation from the magnetron enters the chamber of the stoveon a special waveguide. A special design at the door, as it contains a special glass, which includes both plastic and metal mesh. The latter reflects the microwaves and prevents them from moving out of the chamber. Many hotels petrovac montenegro their location, have a large number of stoves,all have the same design. Differences can only be found in small things. Heating food is very interesting going on. Radiation drives the molecules of sugar, water, fats. And movement is the allocation of energy, in addition, billions of molecules hit each other, which is also accompanied by the release of heat. Consequently, food warms itself, and waves only contribute to this.
