What is the principle of the heating pack of self cooking hot pot?

The heating package of self-cooking hot pot has different formulas, but in general, it is mainly quicklime, activated carbon, iron powder, aluminum powder and other ingredients, and quicklime and water will release a lot of heat after contact, which is the main heat of the heating package**.

Activated carbon is an adsorbent, which is conducive to the adhesion of various active ingredients, full contact and chemical reaction. Iron powder and aluminum powder can release a small amount of heat by reacting with oxygen, and the heating package is packaged with high-density non-woven fabric, and if there is no flame, it basically cannot reach the state of spontaneous combustion.

Self-heating hot pot uses food self-heating technology, which is also used for self-heating rice. Self-heating hot pot is a sandwich structure, in which the upper lunch box is used to hold ingredients and water, and the lower layer is used to hold the heat pack.

Place the ingredients on the top layer and add water, then remove the heating pack from the sealed plastic bag, place it on the bottom layer and add some water. Then quickly put the upper lunch box and close the lid, open the ventilation hole, and wait for the lower heating pack to take effect, and you can eat in 10 to 15 minutes.

The main components of the self-heating hot pot "heating package are iron powder, aluminum powder, coke powder and quicklime, etc., quicklime is easy to undergo chemical reaction when encountering water, releasing a large amount of heat, and rapid oxidation of iron powder and aluminum powder will also release a large amount of heat.

Experiments were conducted on samples of self-heating hot pots to test their safety. The experimental items include appearance and packaging label inspection, surface temperature of the pot body, gas release from the reaction of the heating package when exposed to water, secondary water addition reaction of the heating package, composition and content of the heating package, etc.

Precautions for using the heating pack of self-cooking hot pot:

Before using self-heating hot pot, you must read the instructions for use of the product and operate in strict accordance with the prompts, especially do not use it in a closed and narrow environment such as a car, and avoid open flames; There is a vent hole on the lid of the self-heating hot pot, if the vent is blocked, it is easy to cause a small **, and even burn people, everyone must open the vent, and it must have a place to relieve pressure; 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 from bursting; Never keep out of reach of children.

In addition, the convenient hot pot garbage after use should avoid a large amount of accumulation or direct contact with water, and be classified in accordance with the relevant provisions of domestic waste management, and the heating package after use should be classified and disposed of according to hazardous waste.

Hello, dear, I am happy to answer for you! Nothing is a problem. Self-heating hot pot can heat water, but in general, cold water is fine.

Self-heating hot pot is the principle that the heating bag composed of coke powder, activated carbon and other ingredients can be heated and boiled when exposed to water, so whether it is cold water or hot water, it has no effect. However, in order to avoid scalding, it is best to add cold water, because the heating bag of the self-heating hot pot can soar to 96 in one minute, and the temperature will rise faster if you put hot water. Therefore, from the point of view of safety, it is better to use it cautiously according to the instructions.

I hope mine is helpful to you! [Compare hearts].

The heating principle of self-cooking hot pot comes from the heating package inside the packaging box. This heating package is widely used, the main ingredients are sodium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime composed of a bag, injected with cold water, it can be heated to more than 150, and the temperature of steam can reach 200, used to steam food.

Self-heating packs are available 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 self-heating pack itself does not come into contact with food, and the ingredients inside are not mysterious, as long as you avoid burns, you can eat it with confidence!

1. The heating package 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 high temperature can be maintained at 15-20 minutes, and the food heating hot pot can be reduced to 100, and it can be reduced to 60 after 60 minutes, which can continue to heat the food to about 120 minutes. The whole set of products will not cause any pollution when heated, and there is no potential safety hazard.

2. The lunch box is made of polypropylene, which is a kind of heating plastic resin made by propylene polymerization. Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer, polypropylene has good heat resistance, and is not deformed at 150 degrees under the condition of not being subjected to external forces.

3. This technology is also used in the military equipment of various countries, and the use of this heating package in foreign countries is very wide. Is it safe to use? First of all, the heating pack is not directly connected to the dish, and this technology has been used in military equipment for many years.

During field training, a heating pack is used to cook food. The country's military equipment is very advanced, so a lot of military equipment is very popular in society.

4. There are such products on the market, such as self-heating rice, self-heating canned food, etc.

The biggest difference between the heating package of self-cooking hot pot and the heating package of warming babies is that there is an extra 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 heating package of self-heating hot pot is generally composed of sodium carbonate, calcined diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime, etc. The main reactant is quicklime.

The heating pack before heating is hazardous waste and contains quicklime that is at risk of heat release.

The heated heating package is dry garbage, that is, other garbage, which refers to other domestic garbage except for the best possible materials, hazardous garbage, and wet garbage.

Heating water has the same effect as adding cold water. The material of the heating package is sodium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, and quicklime to form a bag, and the temperature of water can soon reach more than 150, and the steam temperature can reach 200. The principle of heat generation is that a large amount of heat is released during the reaction of quicklime (CAO) with water to produce calcium hydroxide, and this process is independent of the reaction temperature.

Self-heating hot pot is the use of coke powder, activated carbon and other components of the heating package can be heated and boiled when exposed to water, but in order to avoid scalding, it is best to add cold water, because the heating package of self-heating hot pot can soar to 96 in one minute, if you put hot water, the temperature will rise faster. Therefore, from the point of view of safety, it is better to use it cautiously according to the instructions.

If hot water is added to the bottom of the self-heating hot pot, it will cause the contents of the heating package to react with the hot water, resulting in heat dissipation.

The heating pack at the bottom of the self-heating hot pot heats the water, so that the food on top will heat up faster.
