With the development of technology, hot pot, rice, etc. have launched self-heating products. They can be eaten as long as they are heated with a heating pack, which is convenient and fast. Many friends found that the heating pack never heats up when eating self-heating hot pot. What’s the matter? The wordgen heating pack manufacturer will answer for you.
The main substances contained in the hot pot heating pack are quicklime, activated carbon, iron powder, aluminum powder, etc. The quicklime contained in it will release a lot of heat after contacting water, thereby achieving the purpose of heating food. If it is a self-heating hot pot, then it will generally be divided into an upper structure and a base structure, and the heating pack is placed in the base structure. Generally, you only need to disassemble the heating pack and put it in it, and then pour in an appropriate amount of water, so that it can generate heat and steam, and then put the food to be heated on it, cover the lid and it can be heated.

Why is the hot pot heating pack not hot:

1. No water: The main ingredient in the hot pot heating pack is quicklime. This substance will produce lime and release a lot of heat after contacting water, but it will not heat up when it does not contact water.

2. Poor quality: Some hot pot heating packs will add some other substances, such as sodium carbonate, calcium chloride and other salts, to absorb the trace moisture in the package. If the quality of the heating pack is poor or it is placed for too long, the quicklime will gradually lose its function and no longer heat up.

Self-heating hot pot hot water or cold water

1. Regarding the question of whether the self-heating hot pot should be heated or cooled, we mainly need to know the principle of its heating. The self-heating hot pot uses the principle that the heating pack composed of coke powder, activated carbon and other ingredients can heat up and boil when it comes into contact with water, so it can be used normally regardless of whether it is hot water or cold water.

2. In some cases, people will choose to add cold water to the self-heating hot pot. First, it is convenient to use, and second, adding hot water can easily cause scalding. Because the heating bag of the self-heating hot pot can soar to 96°C in one minute, hot water will cause heating faster, thus causing danger.

3. We should use it carefully according to the instructions and be careful to touch it during the heating process to avoid dangers such as scalding.
