Everything you Need to Know About the Microwave

What is a Microwave Oven?
The microwave oven is a family appliance that has revolutionized advanced home kitchens. It is designed to cook food quickly by using especial electromagnetic radiation that heats objects from within. It is designed and chiefly used to promptly heat foods, and is most commodious for differently time-consuming tasks such as melting butter or inflame water. Unlike traditional ovens, microwaves cook food from the at heart preferably than from the external. While it was primitively used in commercial kitchens, it is now most popular in homes and the workplace .
How a Microwave Oven Works
A microwave works by sending electromagnetic waves at a frequency of 2.24 gigahertz and a wavelength of 12.2 centimeters through food. This in turn causes the water molecules in the food to vibrate, and the resulting friction with other water molecules causes it to heat up. This is how food cooks from the inside in a microwave. It is besides why freeze food and dry food ( such as rice ) doesn ’ triiodothyronine cook as efficiently : freeze moisture and objects lacking in moisture do not respond quickly or uniformly to microwave radiation. To ensure that food cooks more evenly, many microwave ovens feature a rotating home plate to turn the food around during cook .
The microwave oven is the consequence of an accidental discovery made by Dr. Percy LeBaron Spencer, a self-taught electronics engineer working for the Raytheon Corporation. In 1946, while working on magnetron vacuum tubes in pastime of better radar technology, he walked by a vacuum tube and discovered that his sugarcoat bar had melted in his pocket. He realized that the microwaves from the vacuum tubes could cook food, and experimented by putting popcorn kernels in the same location. This resulted in the world ’ sulfur beginning batch of microwave popcorn. In 1947 Raytheon produced the first Radarange microwave oven, which at over 750 pounds and 5 feet in stature, monetary value over $ 2000 and was only used in commercial kitchens. Raytheon authorized the Tappan Stove Company to use microwave oven engineering in 1952, but the first consumer-grade Tappan oven, released in 1955, cost over $ 1000, which priced it out of the marketplace. Raytheon then bought Amana Corporation in 1965, who then released a counter-top Radarange microwave oven in 1967 for $ 600, which still made it quite expensive for households. initially, microwave ovens were more popular in Japan than America, but by 1975 Americans had become comfortable with microwave ovens to the point that they were outselling boast ranges. By 1976 microwave ovens, which were give in 52 million american households, were more popular than dish washing machines .
Microwave Parts and Accessories
All microwave ovens are built using respective basic parts. These include a fuse which is connected to the exponent cord ; this can shut the microwave down in shell of overheating or a bypass. then there is a high-voltage transformer which passes electricity to the future device, which is a magnetron ; these two parts serve to regulate the microwave radiotherapy levels that are needed to cook the food. The microwave radiation created in the magnetron moves through a wave guide device which is located above the oven ‘s cavity where the food is placed. The microwave radiotherapy then passes through a roll stirrer blade and bathes the food, causing it to heat up. The walls of the oven cavity are made of metallic to reflect the radiotherapy inward toward the food. A safety switch exists in all mod microwave ovens ; this shuts off all microwave energy whenever the oven door is opened. Microwaves have timers which mechanically stop microwave after a specify time period of time. Most modern ovens have clocks, digital timers and rotating turntable plates to turn food while it’s cook ; modern ovens can be programmed by keypads. Microwaves can besides have removable racks and sensors that are designed to prevent over-cooking .
Different Types of Microwave Ovens
The counter-top microwave oven was the first to reach the grocery store. Since then, over-the-range ( OTR ) microwaves and cabinet-mounted microwave ovens have besides entered the commercialize. Counter-top microwaves are the cheapest and most mobile ; while they take up cherished anticipate space, the advantage is that they can be taken from one house to another, if necessary. OTR and cabinet-mounted microwave ovens save counter space, but they are more dearly-won, immobile, and may need to be installed by a professional. Convection microwave ovens have heating elements and fans which cook the food in external heat, which cooks the food from the outside a well as the inside.

Energy Efficiency
Energy custom rates by microwave ovens typically range between 750 and 1100 watts. This is higher than a refrigerator, but lower than a clothes iron. The kilowatt-hour per unit custom ranks at about 200 kWh, which is more than a color television receiver but less than an electric oven. To bring a cup of water to a boil, a microwave oven uses 25 % more department of energy than an electric stove ; however, this dispute amounts to less than a dollar of department of energy use per year. Re-heating food in the microwave, on the other hand, uses 80 % less energy than re-heating in a conventional oven. This confirms the perception that one of the microwave ‘s basal benefits is re-heating food or cooking smaller portions .
Benefits of Using a Microwave Oven
Microwave ovens are faster than conventional ovens for cooking and re-heating. Some vitamins are retained when food is cooked in the microwave than when it is cooked in a regular oven, because longer cooking times destroy beneficial nutrients in food. Microwave ovens entirely use electricity, not gasoline, charcoal or oil, which reduces their carbon paper footprint and eliminates befoulment beyond that which is created in the production of electricity. Microwaves do not brown foods, particularly proteins. dangerous organisms have less prison term to thrive on food that is cooked in the microwave because the food is brought to a high temperature cursorily and can be served good away .
Safety Features
In accordance with US Food & Drug Administration regulations, all modern microwave ovens are designed with excess shut-off switches that stop the microwave march a soon as the door is opened. Some come with sensors that detect steam or temperature levels and stop cooking at a certain point to prevent food from being dried out. Microwaves are besides required to meet a Federal standard which says they can not emit more than 5 milliwatts of radiation per square centimeter beyond 2 inches from the unit ; this prevents any electric potential damage that could be done to pacemakers .
Effects on Food and Nutrients
Microwave ovens can reduce the come of vitamins B, B1, C and E in foods. Microwave ovens can besides damage the protein and amino acid contents in meats and reduce the food ’ s nutritional measure. however it is often better than boiling the lapp foods, which will remove tied more of these nutrients because nutrients are lost through prolong exposure to estrus. It is recommended not to use microwave ovens to warm up bottled breast milk, because it can reduce its nutritional value ; it is advised to heat up summit milk under hot water alternatively .
Microwave Hazards

Microwaves are equally well known for their hazards as they are known for their uses. The Food and Drug Administration has found that microwaving certain foods may result in the creation or collection of acrylamide, which is considered to be a cancer-causing chemical. In summation, other studies suggest that microwaving generates more acrylamide contaminant than frying and higher-powered microwave ovens generate more than lower-powered ones. Water can be superheated in a microwave oven to the point where it will erupt violently and cause burns ; this can happen when water is microwaved in a very placid container with no cracks or scratches. Another known gamble with microwaves is the danger of metallic objects sparking inside the oven cavity, which can lead to damage to the oven. This is caused by microwave energy reflecting chaotically off of metallic surfaces, peculiarly abrupt ones like forks and mismatched surfaces like crumpled aluminum thwart. Properly shaped metal objects such as browning pans that microwave pizzas come packaged in, besides reflect this energy up into the food, which results in a browning effect that is not normally achieved in a microwave oven. mastermind exposure to microwave radiation can cause hard burns, which is why safety mechanisms exist to stop the oven from cooking when the door is assailable. Certain plastic containers can melt and be ruined by microwave ovens .
however, there are besides perceived hazards that either are untrue or are highly improbable to always occur. For example the menace to pacemakers has been all but eliminated due to regulations that restrict microwave radiation sickness end product, and modern pacemakers have besides been designed to be shielded from such emissions. radiation injuries are about impossible due to the safety features of modern microwave ovens, and contrary to some rumors there is no nuclear radiation produced by these devices .
Safety Tips for Microwave Ovens

  • A microwave oven should not be operated if the oven door is damaged or there are problems with closing it securely.
  • Metal objects should not be placed inside ovens unless they are designated as safe for microwaves.
  • Liquids heated inside a microwave oven should be handled cautiously, with protective mitts.
  • Microwave ovens should be cleaned regularly and should not be operated while empty.
