Microwave+Oven

Microwave ovens, once known as a luxury gadget in the kitchen, are now in over 90% of kitchens in America. This once very large counter top hog has been refined to a much smaller unit. Technology made it possible to produce sleek and more modern designs, which have become an attractive part of the modern kitchen. The reduced cost of the microwave oven has added to their popularity. Initially, people were afraid to have microwave ovens in their homes. Radiation poisoning and sterility were among the fears associated with microwave ovens. Fear of the unknown health risks did not help to push sales up in the beginning. In 1967, the Amana Corporation was the first to introduce the original personal microwave. Microwave ovens heat food by dielectric heating. Dielectric heating is accomplished when the heat polarizes molecules that are in the food that is heated by microwave radiation. A turntable inside the microwave can help with more even energy distribution, eliminating dead spots and hotspots. Microwave cooking is not the answer for all types of cooking. Food cooked in a microwave will not brown, leaving an appearance which is not very appetizing. Unlike the conventional oven, the microwave oven does not bake food. The concept of microwave cooking was discovered by accident. In 1945, an employee of Raytheon, Percy Spencer was building magnetrons for radar sets. While working on a radar set, he realized a chocolate bar in his pocket had started to melt after being exposed to radar with the microwaves. Spencer was surprised and decided to experiment by building a metal box, create an electromagnetic field and feed microwave power into the box. This experiment showed how food temperature increases with microwave energy. This was the beginning of the microwave oven. In October 1945, Raytheon applied for a United Sates patient. Radarange produced the first commercial microwave in 1947, which was 5 feet 11 inches tall, weighed 750 pounds and was sold for $5,000. Soon, many other companies entered the microwave market. The early models were for restaurant use. It used three kilowatts of electricity. Today’s microwaves use three times less energy. Other companies introduced commercial microwave ovens and in home use microwaves with little success. Later, technology improved and smaller compact unites were produced. In 1967, Amana introduced a small countertop microwave costing $495.00. By the 1970s, prices became much more affordable for the average American family. In a Chicago trade show, the microwave oven was shown and demonstrated. In 1970, sales in the United States rose to 40,000 and by 1975 one million units had been sold. Microwave ovens were in 25% of American households by 1986. This was the beginning of microwave cooking in the home environment. There are many advantages to using a microwave oven compared to a conventional oven or barbeque. Microwaves turn off when the time that has been entered on the pad runs out. Specially designed, microwave cookware usually does not get hot in comparison to cookware in a conventional oven. Microwave cookware and food cooked in a microwave usually don’t get hotter than 212 degrees Fahrenheit. The lower cooking temperature does not allow the development of carcinogenic like tar and char. Microwave cooking does have some problems. Uneven cooking and heating can be a problem because of the short time needed to heat or cook food. The lower cooking temperature is not hot enough to kill bacterial contamination. Currently microwaves come in a variety of sizes and colors. They can fit into even the smallest kitchen. They are idea for college students in small dorms and provide a safe way of preparing foods. The smallest are called or desktop units. Compact units dominate the market fitting easily in any kitchen. Medium capacity is considered more of a family size microwave. The large capacity microwave can accommodate larger dishes and food and have higher wattage. Build in models are made to mount over a range and some are built into a cabinet. Build in models are usually more expensive. By 2015 throughout North America and Western Europe, the world market is expected to reach 72.5 million. As their products in so many homes are becoming older, the replacement demand increases. Of course, newer models with different features and more modern designs also add to the market. All of these factors will greatly add to the market helping it reach the projected numbers. New market research shows that currently Europe and the Asian market dominate the global microwave oven market. Today, microwave cooking has taken on many different tasks. Reheating and defrosting frozen food is the most common duty of the microwave. Today, many different types of commercially prepared foods can be reheated in the microwave allowing quick and easy preparation of food. The microwave oven has been popular for many years. People have become use to the ease and convenience of the microwave. To most, it has become an appliance we cannot live without. The need for the convenience of the microwave will continue to fill the growth of the microwave over market.
