What is the heating principle of lazy spicy hot pot?

Self-heating hot pot is a convenient food that is heated by heating the heat pack and fully heating the ingredients in the pre-cooked food package and the bottom of the pot.

The self-heating bag is composed of roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, etc., which will be heated up in 5-10 seconds after cold water, and the temperature can rise to about 85 to heat meals or steam food, and can be kept warm for more than 2 hours.

Self-heating packs come in different formulations, but broadly include four types of ingredients:

1.The main thing is quicklime, the scientific name is calcium oxide, which can produce hydrated lime after contact with water, and the scientific name is calcium hydroxide. In this process, a large amount of heat is released, which is the main heat of the heating pack**.

2.Secondly, the heating package contains components such as diatomaceous earth and activated carbon, which are typical adsorbents. Its loose and porous structure is conducive to the adhesion of various active ingredients, full contact and chemical reaction.

3.The heating package usually contains salts such as sodium carbonate, calcium chloride, magnesium sulfate, etc., which are mainly used to absorb the trace amount of water that penetrates into the package, prevent the gradual failure of calcium oxide, and play an auxiliary role in the chemical reaction.

4.In addition, iron and aluminum powders are also commonly found in heating packs, which can release small amounts of heat by reacting with oxygen. It can also form a "galvanic cell" effect with activated carbon, water, and salt, and release heat through redox reactions.

The heating principle of lazy spicy hot pot is as follows: the biggest difference between the heating package of lazy hot pot and the heating package of warm baby is that there is one more quicklime. Because the warm baby is heated by the redox reaction caused by oxygen infiltration after the protective film is removed, the materials in the material package are mainly designed to form a galvanic battery to achieve continuous heating.

The heating pack of lazy hot pot is based on the addition of water to initiate the reaction, and the principle of galvanic battery is also used to provide a continuous and stable reaction.

The main ingredient of the lazy hot pot heating pack:

Sodium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime.

Ordinary hot pot generally uses the principle of electromagnetic heating. Electromagnetic heating refers to the addition of a certain amount of electrical energy to an object to generate heat inside the object, thus heating the object.

When the current passes through the magnet, a magnetic field will be generated, and the electromagnetic induction generated in the magnetic field will produce heat energy, which will heat the boiler on the base, and then heat the food.

Of course, there are also hot pots that are heated with electricity, and their heating principle is that after the electricity is energized, the resistance inside the electricity will generate heat, and the heat will be transferred to the bottom of the middle core pot, so that the bottom of the pot pot will become hot.

The heating principle of self-cooking spicy hot pot is to quickly release heat through the reaction of quicklime, sodium carbonate and water in the heating package to provide the initial heat, and then release the heat through the continuous oxidation of iron powder, aluminum powder and magnesium powder.

The heating pack brings the temperature of the water to more than 90 degrees Celsius and heats the ingredients through the high-temperature water vapor it produces.

Self-cooking spicy hot pot is dangerous in the heating process. Therefore, the following points should be paid attention to when eating self-cooked spicy hot pot:

1. There is a ventilation hole on the lid of the convenient hot pot. If the vent is blocked, it is easy to cause small ** and even burn people.

2. Be sure to use the heating package in strict accordance with the instructions, and pay attention to opening the ventilation holes during the heating process to avoid accidental injury.

3. If you use a glass dining table at home, it is best to add a heat insulation pad under the self-heating food to avoid the glass bursting.

4. The food is a dangerous goods in aviation, when taking the plane, do not carry or check in such food, in addition, do not put it out of the reach of children, to prevent children from blindly using the heating package to cause danger.

It is not dangerous, it does not need fire if it is not plugged in, and it is as safe as the army is equipped with a heating pack and food. I ate the Ba Ding red lazy self-heating hot pot, and the heating bun does not come into contact with the food.

It is the same as the food principle that the troops on field missions are equipped with fever kits, so it can also be proved that the fever kits are not harmful to the body and are very safe. And the Ba Ding Hong lazy self-heating hot pot I ate is all heated without contact with the food, and it will not damage the ingredients.
