Self-heating hot pot meal is a new type of hot pot that has become particularly popular in recent years, belonging to a kind of fast food. The self-heating pot bottom and ingredients are separated, and most of the ingredients have been processed at high temperatures, so they do not need to be cooked for a long time like a traditional hot pot. Therefore, the use of this self-heating hot pot meal is very simple. Some people only need to use boiling water to cook the food. So, what is the principle of self-heating hot pot meals?
Self-heating hot pot meal is a kind of fast food. Self-heating hot pot meal does not use fire or electricity. It mainly consists of ingredients, ingredient pot, pot cover, outer pot, and heating package. After its initial introduction, more and more catering and food companies have joined in. Many companies have started doing business in self-heating mini hot pots, from making hot pot ingredients to setting up chain hot pot restaurants. Although self-heating instant hot pot is delicious and fast, it has certain safety hazards. The heating package of self-heating food is flammable and explosive. Consumers need to be extremely careful when using them, and they are not allowed to be carried on trains or airplanes.
The principle of the self-heating hot pot meals is that quicklime will release heat when it encounters water, producing steam to cook food. The self-heating hot pot meal has two layers. Before eating, only put the ingredients with the bottom material on the upper layer, and then put the heating bag on the lower layer and add cold water. It can produce heat to heat the self cooking hot pot. When the chemical substance in the heating bag reacts with water, the heating will automatically stop.
The main ingredients of the heating bag in the self-heating hot pot meals are calcined diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime, sodium carbonate, etc. Different businesses may have different compositions, but the heating principle of the self-heating hot pot meal is that quicklime will turn into mature lime when it encounters water, releasing heat and producing steam to cook food.
Although the bottom is heated, the self-heating hot pot will not burn because there is water on top, which will lower the surface temperature of the hot pot and prevent the temperature from reaching the ignition point. When the water is heated to a certain temperature, it will be converted into steam and take away more heat, making the self-heating hot pot not burn.
After understanding the principle of the self-heating hot pot meals, it is also important to note that it will not continue to heat. The chemical materials inside will stop heating on their own after reacting, and the remaining residual heat can maintain for about an hour. Once the heating bag encounters water, it will immediately heat up within 3-5 seconds. When using it, be careful not to burn yourself.
