The principle of self-heating hot pot is to quickly release heat through the reaction of quicklime, sodium carbonate and water in the heating bag to provide heat, and then release heat through continuous oxidation of iron powder etc.

The heating pack does not come into direct contact with food, and the containers holding food will not migrate and release toxic substances at high temperatures, so it is food safe

.

Self-heating hot pot is a kind of instant food. Self-heating hot pot does not require fire or electricity. It is mainly composed of ingredients, ingredient pot, pot lid, outer pot and heating pack. The heating principle is to use the material in the heating pack to contact water to release heat, so that the food in the upper ingredient pot absorbs heat and the temperature rises. In addition to "self-heating hot pot", it is also called "micro hot pot", "clear boiling hot pot", "self-heating hot pot", etc.

Although self-heating instant hot pot is delicious and fast, there are certain safety risks. The heating packs of self-heating food are flammable and explosive. Consumers should be very careful when using them, and it is dangerous to take trains and airplanes. No carry-on allowed.

The main ingredients of the heating pack in the self-heating hot pot are roasted diatomite, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime, sodium carbonate, etc. Different merchants may have differences in ingredients. , but the heating principle of self-heating hot pot is that quicklime turns into slaked lime when it meets water, thereby releasing heat energy and generating water vapor to achieve the function of cooking food.

Although the bottom is heating, it will not cause the self-heating hot pot to burn because there is still water on it. The water will lower the surface temperature of the pot so that the temperature will not reach the ignition point, and when the water is heated When it reaches a certain temperature, it will be converted into water vapor and evaporate, taking away a lot of heat at the same time, so the self-heating hot pot will not burn.

The self-heating hot pot will not heat all the time. After the reaction of the chemical raw materials in it is completed, it will stop heating on its own, and the remaining waste heat can be maintained for another hour or so. Once the heating pack encounters water, it will heat up immediately within 3 to 5 seconds. We should also be careful not to burn ourselves when using it.
