Why does a microwave oven turntable rotate in either direction?
The turntable in a microwave oven is driven by an alternating current motor which may start in either direction at random and continues to travel in that direction until stopping. The reason for using a turntable in a microwave oven is that the microwave energy is not evenly distributed across the oven. The turntable allows the food to receive an equal amount of energy by turning across the uneven microwave field. The microwave energy is turned to heat within the food. It actually does not matter in which direction the turntable rotates in order to evenly cook the food.

Answer . \nYes and no. It cook evenly food needs rotated, a turntable will eliminate the need of rotating 1/2 way through the cooking.. Answer . I've had both, and I vastly prefer the one with turntable. A major problem with microwaved food is heating unevenly. A turntable virtually eliminat…es the problem. Also- put a saucer in your microwave, and put the plate or microwave dish on top of it. It will heat more quickly, and more evenly, because the waves can enter the food from the bottom as well as top & sides. (MORE)

Microwaves have helped Australians the same way they have all others who use them. Use the link to another question here in the forum to find the answers.. Bon appÃ©tit!
Microwave radiation is used in a microwave oven. Microwaves are aform of electromagnetic radiation - radio waves - and the ovenoperates right at about 2.45 gigahertz. That's 2,450,000,000 hertzor cycles per second, if that makes more sense. This non-ionizingradiation works directly on molecules that… have an electric dipole,and it will cause them to try and align themselves with theincoming radiation. This is called dielectric heating, and theincreased energy appears as increased molecular motion, which isexpressed as heat. (MORE)
A microwave oven is a cooking appliance, which is predominantly used for more rapid cooking and heating than some other forms of heating. The heat in a microwave oven comes from the excitement of molecules in the food, primary the water molecules (dielectric heating). The waves emitted from a magne…tron tube ( klystron ) are channeled into a shielded metal compartment, where their energy is absorbed by the food molecules, raising their temperature quickly. The molecules in some foods, especially those containing large percentages of fats or oils, can reach a much higher temperature than the boiling point of water. These can heat rather quickly and may spatter. Popular uses of microwave ovens include heating water for coffee or tea, quickly reheating refrigerated foods, and popping popcorn. The ovens have become a staple appliance in Western kitchens since their invention in 1947. Because the wavelength is the same as early radars, the original microwave from the Raytheon Corporation was called the Radarrange. (MORE)
BECAUSE IN ORDER TO HEAT UP THE FOOD IT NEEDS TO GO SLOWLY TO GET THE TRUE HEAT!
The microwave oven was invented by Percy Spencer. The microwave wasfirst called a Radarange before the name was changed.
I was searching for the same answer & arrived at this. From what I know, microwaves resonate on the same frequency which causes water to gain heat from. Seeing as water loses its liquid state at 100 degrees Celcius, I assume that a microwave doesn't get much hotter than this.
.... Convection microwave ovens combine a convection oven with a microwave oven to cook food with the speed of a microwave oven and the browning ability of a convection oven. Another form of a convection oven is the commercial impingement oven . This type of oven is often used to cook pizzas …in restaurants. Impingement ovens have a high flow rate of hot air from both above and below the food. The air flow is directed onto food which usually passes through the oven on a conveyor belt. Air flow rates can range between 1-5 mÂ³/s. Impingement ovens can achieve a much higher heat transfer than a conventional oven. Like the "impingement oven" a convection oven usually has the radiant elements in view of the food, which improves heat transfer and speeds cooking from initial cold start. Some ovens have the heating elements placed in an outside enclosure and hidden from the food. This eliminates radiant heat from direct contact with the food. (MORE)
A turntable in a microwave oven rotates the food being warmed or cooked, with evenness of heating being the aim. A microwave oven is a sealed box, a Faraday cage, into which microwaves--nonionizing radiation of about 2.45 GHz frequency--are injected. The microwaves are generated by a magnetron and f…ed into the box at only one point via a waveguide. So better ovens will use a microwave stirrer, a turntable, or both to help the microwaves more evenly reach the food. (MORE)
Microwaves are electromagnetic waves that occur on the EMR (Electromagnetic Radiation) scale above radio/tv waves and below infrared and visible light waves. They are used in cooking devices (microwave oven) and as carrier waves for cell phone and other communication devices. In other words, a "m…icrowave" is a type of electromagnetic radiation (like visible light waves, tv waves and so on), and a "microwave oven" is a cooking device that uses microwaves to heat foods by stimulation of the water molecule.

A microwave is a form of electromagnetic radiation in the frequency range between 300 MHz (or 0.3 GHz) and 300 GHz. A microwave is also the "shorthand" name we give to a common appliance called a microwave oven. Are they the same? Whether or not microwave ovens are the same as microwaves depends …on the application of the term. Microwave ovens are called that because they contain a microwave generating device and direct the radiated electromagnetic energy (the microwaves themselves) into a cooking space (called a cavity) to heat drinks or food, or even to cook things. Say an appliance salesman is saying to his/her junior helpers, "Arrange the microwaves on the shelves." This refers to the microwave ovens. It's not about electromagnetic energy called microwaves. Take the case of an electronics teacher saying to his/her students, "The microwaves are reflected off the metal screen that is used in the construction of the dish." This does not refer to microwave ovens, but the electromagnetic energy itself. (MORE)
According to a document from the Sharp Corporation (refer to the link below; n.b., it is a huge PDF document!): . "1966 R-600 Turntable Microwave Oven Sharp developed the world's first microwave oven to use a turntable, introducing it as Japan's first consumer model." .
It is possible to stack appliances as suggested, but there is a caution. Here it is.. Both units generate heat, and the microwave actually has air moving through it and exiting at an elevated temperature. The installation instructions for both machines must be reviewed and sufficient space made… between and around both machines (including behind them) for the appliances to operate without inordinate heating. If the instructions are not clear and/or your have doubts, you will be wise to consult an appliance technical professional. Note that all these machines have definitive installation instructions.. Should you ignore warnings and "wing it" with the installation, you risk (at minimum) damaging the unit or units. Additionally, a fire can result, and property damage could be considerable. Lastly, people die ever year from the affects of smoke inhalation because they are trapped (or sleeping) inside a burning structure. You may kill yourself and/or a family member, or a friend or relative who is staying over. (MORE)
Microwave energy is electromagnetic (EM) radiation, and microwaveovens use energy at a frequency of about 2450 MHz (2,450 millioncycles per second). This energy is in the microwave band offrequencies, hence the term microwave oven. The frequency is a goodchoice, because it is quite effective in caus…ing dielectricheating in molecules in the food. This is because there are alot of molecules within the food that will respond to the microwaveenergy. These molecules, because they have an electric dipole, willattempt to align themselves with the passing electromagnetic wave.They will be trying to turn back and forth at that 2450 MHz, andthis generates heat, which warms/cooks the food.

"microwave" is technically a slang term for "microwave oven," so there isn't any difference.. If you really want to get technical, a microwave is a little bit of radiation, and a microwave oven sends out the radiation to cook food.
Yes, microwaves can leak out of a microwave oven. The microwaves are directed into the cavity (the cooking space) of the oven, but they can leak around the seal provided by the door. The door seal is the most probable and common place for leaks to appear. (Most of the rest of the cavity construction… does not lend itself to "breakdown" and microwave leakage.) It's not a good idea to slam the door of a microwave oven shut. Shut it gently. And never lean on the door, not when it's shut, and never when it's open. You and the other users of the appliance have control over how it is treated. If you have doubts about the integrity of the door of your oven, call a repair center in your area. Ask about checking for leaks, and they'll give you the scoop. It is cheaper to take a unit in for a leakage check than to have someone come out. Additionally, the meter used by the professional to do this costs a ton of money and has to be calibrated at least annually. (That's why there's a fee associated with the check.) If you (and others) use your oven per the manufacturer's instructions and take care of it, leaking microwaves should not be an issue. But anything that damages the door may affect its seal, and a check is in order. (MORE)

No, a microwave oven isn't considered a revolving oven. A revolving oven is an item of bakery equipment which contains a mechanism that rotates (revolves) trays - a bit like a ferris wheel - of bread, buns, bagels, and so on, ensuring even baking. Many microwave ovens contain a revolving circular… tray which ensures even penetration of microwaves and makes frequent stirring or rearranging of foods during cooking unnecessary; stirring becomes necessary only at regular intervals, and most microwaveable products don't need turning or rearranging when cooked on a revolving tray.

Like many of today's great inventions, the microwave oven was a by-product of another technology. It was during a radar-related research project around 1946 that Dr. Percy Spencer, a self-taught engineer with the Raytheon Corporation, noticed something very unusual. He was testing a new vacuum tube …called a magnetron (we are searching for a picture of an actual 1946 magnetron), when he discovered that the candy bar in his pocket had melted. This intrigued Dr. Spencer, so he tried another experiment. This time he placed some popcorn kernels near the tube and, perhaps standing a little farther away, he watched with an inventive sparkle in his eye as the popcorn sputtered, cracked and popped all over his lab.. The next morning, Scientist Spencer decided to put the magnetron tube near an egg. Spencer was joined by a curious colleague, and they both watched as the egg began to tremor and quake. The rapid temperature rise within the egg was causing tremendous internal pressure. Evidently the curious colleague moved in for a closer look just as the egg exploded and splattered hot yolk all over his amazed face. The face of Spencer lit up with a logical scientific conclusion: the melted candy bar, the popcorn, and now the exploding egg, were all attributable to exposure to low-density microwave energy. Thus, if an egg can be cooked that quickly, why not other foods? Experimentation began... Dr. Spencer fashioned a metal box with an opening into which he fed microwave power. The energy entering the box was unable to escape, thereby creating a higher density electromagnetic field. When food was placed in the box and microwave energy fed in, the temperature of the food rose very rapidly. Dr. Spencer had invented what was to revolutionize cooking, and form the basis of a multimillion dollar industry, the microwave oven. (MORE)
There should be a bar or lever to press at the base of the digit pad. Some older ovens have a spring-loaded catch that only needs a sharp tug.
The microwave generating component of a microwave oven is called a magnetron . The magnetron is actually a vacuum tube (a vacuum diode, actually) that has an associated set of magnets. This tube (the magnetron) is a type of microwave cavity resonator, and it will "ring" electronically at microwave …frequencies when it is powered up. The microwaves generated by the tube are coupled out of the cavity of this device and directed via a waveguide into the cavity (the cooking space) of the oven. (MORE)
It will still heat the food. You may want to stop halfway through the cooking and rotate the food 90 degrees.
Yes. Stir water or any other liquid after heating in the microwave to disperse any spatters. Second answer: Yes. Microwave ovens are specifically designed to heat water molecules.
The microwaves themselves won't kill anything directly, but if you cook something until it boils, then yes the heat will kill the microbes.
The Reason for these is because Some Plastic Can Not Stand the heat that The MicroWave Oven melt produce therefore when you put a unstsble Plastic in the Microwave oven it Will melt Another Response: Certain types of plastic may be recommended for use in microwave ovens because they allow the …microwaves to pass through them. In this way the food inside the plastic container is cooked while the container stays cool. Not all plastics are microwave safe; some will melt. Metal cannot be used in microwaves. Some types of ceramic dishes, which may have metal elements in their glaze, are not safe in microwave ovens. Consequently some companies such as Tupperware, Rubbermaid and Pampered Chef produced lines of plastic cookware specifically for microwave ovens. More recently, studies suggest that molecular particles from some types of plastic migrate into food when heated in microwave ovens. While manufacturers maintain that their products are safe, some medical experts advise using only glass or safe ceramic cookware in microwave ovens. (MORE)
No. Microwave ovens cannot cause or transmit any illness. However, when purchasing or using any 2nd hand appliance, it is wise to clean and disinfect it thoroughly to insure it is sanitary for cooking purposes.
Yes, bacon can be cooked in a microwave oven. There are many, many posts that will tell you how, and you'll find a couple of links below.
Yes, at least up to 275 degrees Fahrenheit. That is all I have tested so far.
it depends on the recipe that you are using, some may call for microwave, others may call for oven
Microwave ovens can sometimes heat food to quickly, too severely, or too unevenly, causing the outside to be cold and the inside too hot. Also, sometimes things can explode inside a microwave oven, so it's good to be careful with what you put in there.
Microwave ovens were used commercially before entering the home cooking market. Raytheon and Litton Industries Inc., both defense contractors, tried to sell microwave ovens in the United States without much success
It is known that mostly everything can be put in a microwave and have the heat on. But on the other hand it can be very dangerous things can explode or even catch fire! So can escargo be cooked in a microwave oven I would say that you probaly could but it would not be as good.
A)Microwaves are electromagnetic waves. The microwave oven generates these and directs them into the cavity where food is placed. The microwaves act on the water molecules in food, and because the water molecules are polar, they will attempt to orient themselves according to the passing micr…owaves. Because the microwaves are waves, they have crests and troughs, and these will cause the water molecules to "flip" continuously. This generates heat, and the heat warms the food. (MORE)
Yes, items in a microwave oven can be said to absorb microwaves. The microwave energy causes what is called dielectric heating, and this activity takes energy from the microwave beam.
No one discovered microwave ovens. They were first used in 1837 or so when a high school dropout discovered that microwaves emitted heat (or something). He noticed this as he reached into his pocket for his chocolate bar, only to find it had melted. He had been working in a lab full of microwaves (t…he radiation type, not the oven). The next time, he brought an egg and some popcorn. The egg exploded, having being cooked from the inside. Later, popcorn was popping everywhere. That was the discovery of microwaves being a potential cheaper use of ovens. Sorry, but that answer is totally i correct. People didn't know how to harness electricity in 1837... it was 1945, and the person whose chocolate bar melted was Percy Spencer of Raytheon (who only went to grammar school). He realized that microwaves heated the chocolate, then tried popcorn. Heat applied for a patent for heating food. After that, he and others at Raytheon worked at designing an oven that could be used for cooking. The result was something that looked like a 5 foot high refrigerator and weighed 600 - 700 pounds. It was in the 1960's that the first table top units were produced. (MORE)
No - you will get food poisoning - do not heat quiche in a microwave oven - use a conventional oven & heat thoroughly
The glass part? Surprisingly, no. The plastic or metal might melt or burn but nothing will happen to the glass part. See, microwaves heat up by sending micro-waves (obviously) that flip the water molecule. Essentially, glass doesn't have any water content so nothing will happen to it. I wouldn't con…sider trying it though. This is assuming you were talking about eye glasses. (MORE)
