How to make self-heating rice from self-heating rice What is the principle? The principle is that self-heating rice contains a kind of self-heating rice in the heating package. The rapid heating of self-heating rice in the heating bag is provided by the reaction of quicklime, sodium carbonate and water, and provides the initial heat. Then alkali metal, calcium oxide, iron oxide powder and electrolytic aluminum powder react with water, releasing a lot of heat and generating combustible gas. The steam temperature can reach 200 degrees Celsius in a short time, and the heat preservation time can last up to 3 hours.

Composition of self-heating rice heating bag: multi-purpose self-heating bag, mainly composed of roasted diatomite, iron powder, aluminum powder, coke powder, activated carbon and salt. After kneading, it can be heated to 60℃ and used for heating in winter. Adding quicklime, sodium carbonate and water can raise the temperature to 120℃ to heat meals or cook food.

After 20 minutes of heat preservation, the temperature is reduced to 65438 000℃, and after 60 minutes, it is reduced to 60℃. The materials used for heating and hot compress in winter can be used repeatedly, and can still be mixed with quicklime and sodium carbonate after use, and then water is added to heat the food.

Once the plastic strip is pulled apart, the water bag will burst. At this time, the heating agent will react with water, so that the heating agent will radiate heat evenly and generate heat as high as 120℃. After 5-8 minutes, when the temperature of the food reaches 55℃ and 70℃, you can eat delicious food. After the heating agent reacts with water, the steam produced is non-toxic and harmless, and it is safe to eat.
