last century - a century of discoveries and innovations.It was invented many devices that are now firmly established in our everyday life.And one of those inventions - a microwave oven.It is a new approach to the preparation of tasty and healthy food.But how does it work?Oddly enough, but his appearance furnace required to the military industry.It is in the radar for the first time began to use ultra-high frequency for detection purposes.In the early 30-ies in a US laboratory workers accidentally cooked the first meal using the microwave generator.This dish turned out sausages.This is the first mention of microwave cooking methods.Today, Italy Rimini 3 star hotels which are popular simply awash microwave different manufacturers.
and in 1945 patented the microwave, however, it had a completely different look, not quite like the one we are used to seeing.It had huge closets, the heart of a magnetron - a special vacuum tube, emits waves in the microwave range.That's the story in a nutshell.In fact, the invention microwave - is the work of thousands of scientists.Today, all furnaces operate on a dedicated frequency - 2450 MHz.According to international agreements, the stove all manufacturers should work exactly at this frequency, so as not to interfere with radars.The basis of any stove - magnetron, its voltage of about 4 thousand. Volt.Mains voltage is small, so you want to increase, which is due to the use of special transformers.Magnetron having a capacity of 850 watts, certainly has a heat sink and fan that when working on and producing blowing device.
radiation from the magnetron into the chamber stove special waveguide.The special design at the door, because it contains a special glass, in which structure there are plastic and metal mesh.The latter reflects the microwaves and does not allow them to go beyond the camera.Many hotels in Petrovac, Montenegro of their location, have a large number of ovens, all of the same design.Differences can be found only in the details.Heating food very interesting is going on.Radiation drives the molecules of sugar, water, fat.A movement - it is the release of energy, in addition, billions of molecules collide with each other, which is also accompanied by the release of heat.Therefore, the food heats itself and the waves only contribute to this.
