Microwave oven

The origin of the microwave oven. When the real cause of the accident, Spain, Sir Percy (Percy Spencer) The employees of Raytheon Company (Raytheon) is a magnetron for use in radar systems. I noticed that Choco bars. Melt chocolate in his pocket while he was in front of the device, the magnetron tube parts are in radar systems. I try not to put any seed corn. Magnetron tube. That is the popcorn.

The next day, the Spanish woman's engineers to test what he had just discovered. By which the raw egg into the pot holes on the side. To see the changes happening within a pot. Then put the magnetron tube near the eggs, raw eggs and then start shaking it up. And when a friend of Mr. Spain's see what they have "egg bombs" full page

This event was so excited to think of a microwave oven at a later time.

2489 Year of Raytheon Company. The patented process uses microwaves to heat food. Later in the year. Fri 2491. Raytheon began manufacturing the first commercial microwave oven, a radar Orange (Radarange) stands for Radar + Range is the first massive oven. With a height of 6 feet (1.8 meters) and weighs 340 kg, using a water cooling system, and are higher than the 3000 watt microwave oven that we use today to 3 times more expensive to five thousand dollars.

Initially, most people who use giant microwave oven is a company dedicated to the military. As a company with expertise in the magnetron. And in restaurants. Rail and marine.

The year 2495-2498. Technology developed by its Japanese name, Tappan magnetron tube can be achieved. And removal system to remove water-cooled. A microwave oven for the considerably smaller size and is available in the household as of the year. Fri In 2513.

The working principle of microwave ovens are different. The oven is electric or gas oven to heat, which causes the heat from the outside to the inside. The microwave oven does not heat the air in the oven. The microwave magnetron inside the microwave and spread of the water molecules absorb this radiation as well.

When microwave radiation is absorbed by water molecules in food. Molecules to vibrate and heat up. If the food consists mostly of water, such as potato or apple pie. The food will heat faster than the outside.

The heat is not uniform throughout, so it may be cooked using the microwave oven to warm the food eating out of hand early. Bacteria could not be destroyed completely, and food poisoning.

Another caution. Is a smooth liquid in the container. Cause the phenomenon of super-heat or high temperature liquid boiling temperature of liquid that when a liquid is not boiling. I took the container out. The cause of the explosion. Then burn your hands or body. The baked eggs or foods packaged in sealed containers may explode as well. Due to the increasing pressure of the steam inside.

Also, be careful to use tin foil. Paper or aluminum foil. And ceramics decorated with metal in a microwave oven. It can cause a fire.
