The college student ordered the takeaway hot pot, and then it fried ...

/>

On August 19, a major three students called for takeaway, and suddenly the fried pan was spate with the cornea. The classmate said that it would explode in ten minutes after cooking, and it was hot oil everywhere. The staff said that checking the monitoring found that it was because of the bottom material, and then the water, and without stirring, the fried pot occurred. The parties are currently in contact with the parties.

In this regard, netizens hot review

"Hot oil and cold water will definitely explode"

Why "hot oil and water will definitely explode"?

We know that all kinds of liquids have a certain temperature when boiling, and this temperature is called boiling point. Under the standard atmospheric pressure, the boiling point of the water is 100 ° C. Taking the linseed vegetable oil as an example, its boiling point is 287 ° C.

Therefore, it is not difficult to find that if you take out a frozen food and put it directly into the oil pan, the oil in the oil pan will be fried. This is because the water on the outer layer of the food reaches the boiling point into water vapor in advance, the oil pan is immediately "boiling", not only will the oil burst, but the food may also be fried. If the flames happen, the fire will spread instantly.

There is another very important reason that water falls in the oil pan. The density of water is greater than the density of oil. As soon as the small water droplets enter the oil pan, it will sink into the bottom of the pot. When the water reaches the boiling point, the water will turn into water vapor, and the density of the water vapor is much smaller than the oil. It must rise to jump out of the oil surface. Therefore, the water falling into the oil pan will cause severe vibration, make sounds and explosions, and splash oil flowers. So "water will definitely burst into the oil pan."

How to deal with the oil pan on fire?

If the water falls into the oil pan, it will cause explosion

So what should I do if the oil pan is on fire?

Many people are cooking food

Due to improper handling

It's really "exploding the kitchen"

Experts point out that edible oils are organic solvents or internal organic solvents, and the proportion of these solvents is less than water. If the oil pan is on fire, after watering, the water cannot be covered, but it will quickly "run" to them, so it will not beolate the effect of isolation of oxygen. At the same time, watering will also increase the contact area between organic solvents and air, making the fire burning more vigorously. At high temperatures, the water will boil and vaporize quickly, and even splash the combustion organic solvents to the surroundings.

Therefore, when an organic solvent combustion accident occurs, if the combustion is violently deflated, it is best to escape urgently. Do not try to extinguish the fire to avoid burns. If the fire is not large, it is limited to the local area, it is best to use a foam fire extinguisher to play a effective flame retardant role.

In addition, covering pots, wet rags, green vegetables, and fire blankets are also effective.

Cover the hot oil pan with a pot cover so that the burning oil fire cannot be exposed to the air and extinguish it, but do not immediately open the lid.

The large piece of wet cloth on hand covers the fire pan that can be covered, and it can also have the same effect as the use of pot lids. Pay attention not to leave a gap when covered. You can also pour dry vegetables or other cold foods along the edge of the pot. The temperature difference between vegetables and food and fire oil is used to reduce the temperature and quickly extinguish the fire.

Finally, we can also prepare fire blankets at home. The fire blanket is actually a small packaging fire bag. Its biggest effect is flame retardant and can be used repeatedly.

The range hood is also easy to cause fire. When the pot is lifted from the stove, the gas stove should be closed first. Do not let the range hood directly facing the flame to prevent the flames of the waste oil particles above. In addition, do not put paper bags or plastic bags in a microwave oven. This will not only ignite paper products, melt plastic, produce toxic gases, but also get angry.
