Who invented the microwave oven? strong> The quickest and easiest way to cook something today is to use a microwave oven. For many years, many home kitchens have an important place due to their ease of use and fast cooking. The movement of microwave radio waves to polarized liquid molecules works with the heat ration resulting from the collision and friction of fast moving molecules with each other.
The Find of Microwave h2>
The engineer working at Raytheon Percy Spencer strong> During World War II, radar was conducting research for vacuum tubes. While experimenting in his lab he noticed that the chocolate in his pocket was warming up. After that he made successful experiments with popcorn and eggs. So Dr. Percy Spencer has discovered by chance that microwaves can be used to heat food.
Percy Spencer strong> studies have shown that high frequency radio waves penetrate certain types of molecules it turned out that they were moving them.
In Boston, Massachusetts, he tested the oven in a restaurant and produced serials. These first bakeries were available for use by hospitals and hospitals as the prices were around $ 5,000.
Raytheon founded a company in 1952 called Tappan Stove for microwave oven production. In 1965, he bought the famous refrigerator maker Amana and produced countertop models of microwave ovens. By the end of the 1970s, many companies began producing microwave ovens strong> for home use, and costs were down. Now, microwave ovens have become a standard home appliance with different designs and features according to their needs. These features have become adjustable cooking power for rotating dishes, digital timers, auto-programming features and de-essing, browning, heating, and many other functions for better cooking.
Diminishing microwave ovens are very popular It has become. In 1986 there were microwave ovens in every four houses in America.
In general, the spectrum is divided into sub-headings according to different wavelengths (frequency) and emission, transmission behavior of the waves. The shortest spectrum from the longest includes electric and radio waves, microwave, infrared radiation, visible radiation, ultraviolet radiation, X-rays, gamma rays and electromagnetic cosmic rays. Microwave frequencies are approximately 0.3 to 30 cm.
Certain features of microwaves allow them to be used in cooking. They can pass through plastic, glass and paper; they are absorbed by metals and by food (especially liquids). A traditional fried dish slowly heats up by sucking up the air surrounding it. Microwaves, on the other hand, heat the food much more quickly because they penetrate all layers at the same time.
The basic microwave oven design is simple, they all work in a similar way. The oven’s electronic motors, relays, control circuits, are mounted in the outer casing where the oven cavity is mounted.
This creates microwaves. Microwaves are transmitted to the rotating fan through the metal waveguide. The fan spreads the waves evenly into the oven. The producers’ designs vary on better distributing microwaves. Some have used dual fans located on opposite walls, while others have created entry gaps that allow microwaves to penetrate both from above and below.
Raw material strong>
Ovens are usually made of single piece folded metal. The inner panels and covers of the oven are made of galvanized or stainless steel and are usually covered with acrylic enamel. The cooking surface is often made of ceramic or glass. The oven contains electromechanical structures and control components.
The feature that distinguishes the microwave oven from other ovens. H2>
In standard heating methods, heat is transferred to the food by heating (the other side is heated by the substance or cismin) a type of heat transfer resulting from the transmission) or radiation.
Thus, a faster heat-up is obtained in the microwave and the processes such as cooking, scalding, drying, pasteurizing, defrosting, sterilization occur more quickly.
Microwave heating is more efficient than other heaters, it has also been demanded by the operators of the mass-consuming enterprises, as it provides advantages. Microwave ovens that make life easier are technological products that always keep their importance as long as they are used correctly.
