How to stop the self-heating hot pot? What is the principle of the self-heating hot pot?

Modern people love to eat hot pot. Beijing's mutton hot pot, Zhejiang's eight raw hot pot, Hangzhou's "three fresh hot pot", Hubei's "game hot pot", Northeast China's "white meat hot pot", Hong Kong's "beef hot pot", Shanghai's "mixed hot pot", Shandong's "mutton soup hot pot", etc., also have unique flavors. And now a convenient self-heating pot has been invented. So how do you stop the self-heating hot pot? What is the principle of the self-heating hot pot?

How to stop heating the self-heating hot pot

The self-heating hot pot will stop heating as soon as the chemical in the heating pack finishes reacting with water. The amount of chemical in the heating pack and the amount of water poured into the box determine the length of the heating time. The heating pack will start heating 5 to 10 seconds after it comes into contact with water, and the high temperature will be maintained for 15 to 20 minutes. After one hour, it will drop to 60°C, and the residual heat will be maintained for about 1 hour.

The self-heating hot pot will not keep heating. The heating will stop when the chemicals in the heating bag react with the water. The amount of chemicals and water in the heating bag determines the length of the heating time. If you want to stop heating as soon as possible, you can pour a small amount of water to end the reaction as soon as possible, but be careful that if the heating time is not long enough, the food may not be cooked.

The heating pack is made of quicklime, diatomaceous earth, activated carbon, sodium carbonate, salt, etc. It will heat up in 5 to 10 seconds when it comes into contact with cold water. The high temperature can be maintained for about 15 to 20 minutes. After one hour, it will drop to 60°C and can continue to heat food for about 120 minutes.

Hot water can speed up the reaction of the chemicals in the heating pack, but it is easy to cause safety hazards, so it is best not to use hot water for heating. During the heating process, it is best not to open the box to stop heating to avoid accidents. Stopping heating too early will also cause the food to not be fully cooked, which will affect health after consumption.

What is the principle of self-heating hot pot

The principle of the self-heating hot pot is that the quicklime, sodium carbonate, iron powder, aluminum powder, activated carbon, diatomaceous earth and other ingredients in the heating bag react with water to produce a chemical reaction, releasing a large amount of heat to heat the food. Quicklime reacts with water to produce a chemical reaction, releasing a large amount of heat during the reaction, and diatomaceous earth and activated carbon play an auxiliary role in the heating process.

The principle of self-heating hot pot is that the quicklime, sodium carbonate, diatomaceous earth, iron powder, aluminum powder, activated carbon, salt and other ingredients in the heating bag react chemically when they come into contact with water. The quicklime in the heating bag is the source of heat for the heating bag. Its scientific name is calcium oxide. It will react chemically when it comes into contact with water and be converted into calcium hydroxide, releasing a large amount of heat during the conversion process.

Diatomaceous earth, activated carbon and other ingredients in the heating pack are typical adsorbents. Their loose and porous structure is conducive to the adsorption of various effective ingredients, allowing them to fully contact and react. Salts such as sodium carbonate and calcium hydride in the heating pack are mainly used to absorb moisture that penetrates deep into the package, and at the same time play an auxiliary role in the chemical reaction.

Iron powder and aluminum powder are also commonly found in heating packs. They release a small amount of heat by reacting with oxygen. They can also form a primary battery effect through activated carbon, water, and salt to generate heat in the redox reaction.

How to eat self-heating hot pot

Before eating the self-heating hot pot, prepare the ingredients first, add water to the heating bag and put it in the inner layer, cover the lid and cook the food before eating. First open the package, unpack the ingredients and seasonings and pour them into the upper ingredient box, then add an appropriate amount of cold water and stir evenly, put the heating bag into the lower box, add an appropriate amount of cold water, cover the lid and wait for about 15 minutes before eating.

1. Food processing

First, open the package, take out the ingredients and seasoning packets in the upper box, then open the ingredients and put them into the upper box, pour the seasoning packet into the ingredients and stir evenly, and then add cold water, just enough cold water to cover the ingredients, and then stir the cold water, ingredients and seasoning packet evenly.

2. Heating treatment

The self-heating hot pot is divided into two layers of boxes, the lower one is the heating layer. Tear open the plastic outer packaging of the heating pack, put the heating pack into the lower box, add cold water to submerge it, then put the ingredient box on top of it and cover it with the lid.

3. Wait for heating

When waiting for the self-heating hot pot to heat up, be sure to open the vent on the lid to prevent burns. Also, do not place the heating box on a heat-resistant table, such as a glass table, to avoid explosion. After heating for about 15 minutes, the ingredients will be cooked. Open the lid and stir evenly to enjoy the steaming hot pot.

How to fix the problem of self-heating hot pot not being cooked

If the self-heating hot pot is not cooked, you can add some boiling water to cook the food inside and eat it. The self-heating hot pot uses the material in the heating bag to contact with water to release heat, so that the food in the upper layer of the pot absorbs heat and the temperature rises and becomes cooked.

Self-heating hot pot is also called "micro hot pot", "clear boiling hot pot", "self-cooking hot pot", etc.

Self-heating hot pot is an instant food that does not require fire or electricity. It is mainly composed of ingredients, an ingredient pot, a lid, an outer pot and a heating pack.

The heating pack of the self-heating hot pot is flammable and explosive. You must be very careful when using it, and it is not allowed to be carried on trains or planes.
