60 contains the history of microwave ovens

Microwave ovens are one of mankind's most brilliant invention . Cooking , heating, defrosting , baking , etc. just basic functions , microwaves can be used for vegetable dehydration, restore food crispy , goods long-term preservation , home warmth, brewed medicine, baking gouache and other applications, it is an appliance in the versatile power .
One , Origin: "Century a spray"
September 1940 , for military radar microwave energy research scientist with the British magnetron sample to cooperate with the U.S. Raytheon communicate .
In 1945 the American engineer Percy • Adams tucked in next to a microwave transmitter found in his pocket melted chocolate .
Pocket why chocolate will melt it ? Lisbon plug seize this phenomenon were carefully analyzed and studied . " Is it the role of the microwave ? " So Sri Lanka has the plug on the microwave corn, eggs and other food in the microwave transmitter next to the test, the results of thermal explosion splash him an egg , which is known to believe that the Lisbon plug Microwave heating perspective of the " century a spray" !
It was found that certain wavelengths of electromagnetic waves can indeed cause food hot. On this basis , he was the first to propose the idea of ​​using microwave heating of food .
Second, the pet name " radar " furnace
In Sri Lanka the Se Qite ideas Imagine A new cooking by microwave heating method produces .
In 1946, Raytheon Company and jointly developed with the Andean plug specialized cooking in the microwave , and get to use the microwave to cook food of patent applications , the following year to get the first microwave patents.
In 1947, the world's first microwave oven launched , there is a water-cooled magnetron 1700W , weighing more than 340 kg , a full six feet tall , product testing , only to be placed in the Boston hotel , its price is also very expensive - $ 3,000 . Since its invention inspiration from the radar device , so the first to be called the " radar " stove, later renamed as "microwave oven ."
Adams himself because the plug outstanding achievements won the U.S. Navy awarded the highest civil award " Public Service Award " , and was awarded the prestigious Massachusetts Institute of Technology Honorary Doctor of Science title.
Lisbon plug when doing the experiment I often subjected to microwave baking, but this did not seem to affect his health : he lived 76 years ( 1894-1970 ) , which indicates that microwave hazards of some alarmist.
Third, the 1967 veteran Microwave
In 1964, the Japanese Ogura Qing Zhi improved microwave magnetron , dramatically reducing the microwave oven prices .
In 1965 , George Foster and Adams • The plug is designed with a durable and inexpensive microwave oven , only in the United States has achieved great success.
In 1967, a microwave and finally weight-loss success , and changed people 's views on the microwave oven , petite body and moves quickly , you only need a few minutes to complete in the past may take several hours to complete the cooking. Amana introduced a microwave oven is priced at $ 495 , and began the journey to become the main family kitchen .

          ( Marking the microwave "downsizing " success Amana Radarange microwave 1967 )

Japan's first microwave
In 1961, Japan's first microwave oven , a little big, almost like bakery oven , reportedly was originally used for the cafeteria .

The world's first microwave oven with turntable
Four , microwave in China
1982 China 's first microwave oven was born in Nanjing
September 1992 the first " Glanz " brand was born in the microwave
January 2000 China 's first advent of microwave networks
June 2001 the world's first pocket-sized portable microwave oven Galanz Microwave Research Center American advent of variable frequency , light weight, high thermal efficiency, relatively effective volume increases , which greatly facilitates field work, travel, vacation outskirts of people .
This is the use of mobile power to microwave cooking vehicle , marine microwave ovens, and later launched a portable pocket-sized microwave frequency , which greatly enriched the microwave products , this product is very popular in European and American markets .

Seven , Microwave Basics
Microwave is a very high frequency electromagnetic waves, usually refers 300-30000 MHz electromagnetic waves. Microwave is a use of electromagnetic waves to cook food in the kitchen utensils .
[1] Principles
The external structure consists of a microwave cavity , the control of panel components. Internal structure of the power supply unit , the magnetron unit , furnace chamber section , the door section composed of four parts . The whole machine is the use of microwave ovens Heart - magnetron , the resulting 50 million times per second, 2.4 billion ultra-high frequency microwave fast shocks in food protein, fat, food categories, such as water molecules , the molecules between collision, extrusion , friction rearranged . In short, both by internal friction heat the food to cook principle .
[2] classification
Microwaves from the function is generally divided into common type, with grill function and other types
Microwave up points from the operating mode is generally divided into mechanical and computer-style
   [ 3] Characteristics
    Microwave is a high-frequency electromagnetic waves, a reflective , penetration and absorption three characteristics .
Reflex : Microwave touch the metal will be reflected back , so the use of specially treated steel plate wall , according to the microwave reflection effect caused by the inner wall , the microwave back and forth through the food , to enhance thermal efficiency. But the furnace not use metal containers, otherwise it will affect the heating time , and even cause the furnace discharge ignition.
Penetrating : Microwave on general ceramics, glass, heat-resistant plastic , wood, bamboo and other penetrating effect, it is best used in microwave cooking utensils .
Absorbent : all kinds of food can absorb microwaves , resulting in food molecules through shock, friction and heat generated . But its penetration of a variety of foods depending on their quality and quantity of the size, thickness factors vary.
[4] Technical Parameters

    Rated frequency : 50Hz
    Microwave frequency : 2450Hz
Door anti-leakage device: door surrounded 1/4λ short-circuit devices. Door interlock safety device prescribe agency , the door opens automatically cut off power
Door open times : more than 100,000 times
[5] functions
    With fried , boiled, grilled , baked , braised, stewed , steamed, braised, reheating and defrosting a variety of cooking methods .
    High thermal efficiency, low power consumption , cooking fast, economical , time-saving than traditional cooking .
    Keep the food original color, smell, taste and nutritional ingredients , so you can play a great chef .
    Can quickly thaw food, and keep thawed food and fresh water .
    Food can be uniformly heated . Hot meals are served without wasting any residue .
Placed in containers or heat-resistant food packaging bag can be heated in a microwave cooking are . Such as ceramics , microwave cling paper , microwave can be answered through , so a bowl of rice, a plastic bag of bread can be heated .
Rarely smoke and hot air, so the kitchen was spotless , forever a clean environment.
[ 6] The main factors affecting microwave cooking
Microwave cooking, heating time control of food is the biggest learning using a microwave oven , use a good chef can also reach the level . Early users , if the time has not yet mastered control , you can try it first with a short period of time , check the cooking effects, such as not cooked , and then increase the heating time , so as to avoid over- cooking , can not be remedied .
Additional heating time is affected by the following factors:
    Food initial temperature : the lower the initial temperature of the food itself , needs to be heated longer .
    Food size: small pieces of food cook faster than large pieces . Therefore, to shorten the cooking time , the best food into less than 5cm square pieces , so that all aspects of microwave energy through its center .
    Food Shape : Food same shape , more uniform cooking . Usually sliced, diced better.
    Quantity of food : the amount of food , the more the longer the cooking time .
    Food Density : microwave energy penetration depth of food within the food according to the different molecular density differences , porous high density food than food by microwaves can penetrate more easily .
Food and water content: water molecules absorb microwaves can be so high water content food cooking better.
Containers : general use round, shallow mouth, and penetration rate of less endothermic container heating works best , if the amount of food a lot , using a large depth of container, stirring heated transit country to avoid uneven heating .
[7] According to family circumstances choose the right microwave oven model
    What to buy what type of microwave oven , depending on the specific circumstances of different families to decide, generally working-class family , home, children and the elderly to use , you can choose simple mechanical-type , while , according to the size of households , choose a different power , such as the three homes, should choose 700 , six or more people should choose 800 ; course also depend on how fast paced life of a family to be, you can choose fast-paced high-power hungry, intellectuals , well- single-family homes as well as young couples should choose a computer model , this model features more, the price is higher , therefore suitable for a knowledge-based economy is relatively wealthy family ; terms of style , luxury and mechanical computer-based remote type , it is also suitable for exquisite style of young families. In addition, like to eat barbecue feature microwaves, better economic conditions , you can choose stainless steel liner type , it is not only luxury , as well as easy to clean and so on.
