Remember there was a video on the Internet about heating grapes in a microwave oven? In the experiment, the researcher found that after two grapes were put into the microwave oven, an electric arc was generated.
The microwave oven is so convenient to use that many people don’t pay attention to it. In fact, it is a “temper”!
By understanding the heating method of microwave ovens, we know why microwave ovens are so dangerous.
Unique heating method
Ordinary cooking utensils are used to produce heat and transfer the heat to the food to achieve the heating effect, such as a stove.
However, the microwave oven itself does not produce heat. Instead, it uses its own magnetron to convert electrical energy into microwaves to oscillate food molecules. The molecules oscillate rapidly at a rate of 2.45 billion times per second. The macroscopic performance of this oscillation is the food is heated.
Because of the special heating method, some things must not be put in, which may damage the microwave oven, or cause fire or explosion.
Things that can’t be put in a microwave
1. Eggs
The traditional heating method is from the outside to the inside, while the heating method of the microwave oven is all uniform heating. This makes it a very dangerous thing to heat eggs in a microwave oven.
Because the heat expansion rate inside the egg will be faster than the egg shell, and a lot of water vapor will be generated in the egg. This steam has nowhere to escape, it will boom~~~
2. Metal tableware
Although metals are stable, heat-resistant, and non-flammable under normal conditions, the unique heating method of microwave ovens can make metal molecules vibrate violently and cause metal tableware to ignite spontaneously.
3. Tin foil
Any metal can not be put into the microwave oven, because tin foil contains metal, neither is it.
4. Paper bag
Any paper objects should not be placed in a microwave oven. Microwave ovens can even ignite metal, let alone flammable paper?
5.Milk carton
Most milk cartons are made of paper or plastic, and even lined with tin foil. No matter which material they are, they are banned from microwave ovens.
6.Plastic container
Most plastics are not suitable for heating in a microwave. The only plastic that can be put in a microwave is polypropylene. If you are not sure, for the sake of safety, do not heat the plastic container unless it is marked as heating.
7. Fruit
Some fruits contain salt ions. Under the vibration of the microwave oven, a strong electric field will be generated, such as grapes, blueberries, cherry tomatoes, etc. It is very likely to cause an explosion when placed in the microwave.
8. Pepper
There is nothing wrong with heating chili, but when you open the door of the microwave oven, the chemicals in the hot chili will irritate your eyes and burn your throat. Promise me not to do this, okay?
9. Liquid
When the liquid is heated by the microwave, the water will not flow, but the temperature will rise. It may exceed the boiling point and there is no sign of boiling.
But if there is a slight movement, such as opening the door of a microwave oven, the water inside will boil violently, causing burns.
10. Do nothing
If the microwave oven is left idling, accidents may also occur. Because nothing absorbs microwaves, the magnetron (the main component of microwave ovens) will eventually absorb microwaves and then ignite spontaneously.
In fact, as long as you don’t put things in disorderly, the microwave oven is very safe, and if used properly, there will be magical skills you can’t expect.
Microwave oven tips
1. Peel fruits and vegetables
1. Before peeling garlic, heat it for ten seconds, and then peel it. It’s not too easy.
2. After the potatoes are soaked in water, use a microwave to heat them up, and they can also be peeled easily.
3. Draw a cross on the bottom of the tomato, then heat it, you can also peel it easily.
2. Dry the food
Foods such as biscuits, dried fruits, etc., not only taste bad, but the taste is also greatly reduced when they are damp. But as long as the food has not deteriorated, just put it in the microwave and heat it, and the texture and taste can be restored.
3. Remove odor
Towels, dish cloths, and sponges are stained with peculiar smells, just rinse them with clean water, and then put them in the microwave for heating for half a minute. It can also play a role in high temperature disinfection.
4. Quickly remove the fish from the cutting board
Wet the cutting board, evenly brush with detergent, put it in the microwave, and heat for one minute. Take it out and simply rinse it. At this time, the cutting board has been fully disinfected.
Of course, no matter how easy to use home appliances, you should also pay attention to daily maintenance, or be careful that they suddenly “strike”!
Daily maintenance of microwave oven
1. There is a statement about the placement
The microwave oven should be placed flat, away from the fire and the faucet. The sides of the oven should be placed in a ventilated place, and a distance of 5 cm from the wall should be maintained to facilitate the diffusion of heat.
2. Check the line
Microwave ovens use electricity. Be careful with all electrical appliances. Regularly check the power cord of the microwave oven, around the door, and door locks. If you find damage or poor closure, stop using it to prevent short circuits or microwave leakage.
3. Keep it clean
Don’t put it away in a hurry after using the microwave. Wipe it with a damp cloth. Keep the inside of the oven clean and dry, especially at the door cracks or openings, and the microwave inlet on the right side of the microwave oven cavity. If food residues are spilled on it It is easy to be carbonized, causing microwave reflection and burning out the magnetron.
