The principle of the heating package is nothing more than a chemical reaction. If you want to heat a lot of meals in the steamer, it depends on 1. Is it enough to react 2. Will the pot itself join the reaction? This requires knowing the composition and specific principle of the heating package. The main components of the heating package are quicklime, calcium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt. The principle is mainly that quicklime reacts with water to exothermic and primary battery reaction.
The reaction time depends on the specific ingredients. The safety of the pot will involve the primary battery.
If the inner wall of the pot is a metal surface, it is not safe. It is likely to form a primary battery with carbon, iron, magnesium, sodium ions-hydroxide and ions-chloride ions, and react with itself. Damage to the pot is a small matter. If the reaction time is long, the pot will leak and it will be broken. If the concentration of sodium hydroxide is high, it may also corrode yourself.
If the inner wall of the pot is well covered with a coating that does not reflect those things, such as Teflon, it may be better. As long as the heating pack does not leak, nothing will scratch the coating.
How to use the heating pack?
1.
Unpack and open the food with the heating bag
2.
Place the heating bag on the bottom layer of the box, remember to pour in cold water! Do not pour hot water.
3.
After the heating bag encounters cold water, it will gradually heat up in about 5-10 seconds! Please cover the lid of the food well! The temperature will rise all the way to about 85 degrees Celsius, which can be kept warm for about two hours
4.
After the heating is completed, pay attention to remove the lid to avoid scalding your hands by steam. The heating bag is simple and convenient. The food heating bag uses the heat generated by the hydrogen gas generated by the reaction between the heating bag and water to heat food. Due to its simple operation, it is favored by many young people
