Therefore, the ancient self-heating food has been favored by young people. people’s thanks.

Self-service hot pot self-heating bags are very versatile. You only need to add cold water to heat them to boiling temperature, and it is possible to boil food. There are different recipes for the heating bags, but they mainly include four types of ingredients.

1. Lime powder, which is likely to form lime after contact with water, will release a lot of heat during the reaction, and is the main source of heat for the heating pack;

2. Ingredients such as attapulgite and charcoal are typical absorbents. It is a porous structure that is conducive to the adhesion of various components and may fully contact and cause chemical changes;

3. Vermicelli and alumina powder may release a small amount of heat by reacting with CO2, and may also have a “battery reaction” effect with water and salt, releasing heat through a redox reaction;

4. Potassium carbonate and mannitol are capable of absorbing a small amount of water in the soaked package, which can effectively prevent the calcium hydroxide from taking effect temporarily and play an auxiliary role in the reaction.

The solid-state quantitative analysis heating pack itself is not in contact with food, so everyone can learn to put it down and use it!

Self-service hot pot self-heating bags are currently very widely used. This method has been used for many years. It is very convenient and popular to use heating bags to heat food during outdoor training.
