The heat source technology of self-cooking hot pot comes from patented heating bag. This small heating bag contains iron powder, aluminum powder, calcium oxide, coke powder, activated carbon and quicklime, which will react chemically when they come into contact with water. The main reaction principles involved are: CaO+H2O=Ca(OH)2 and a lot of heat 2al+2nNaOH+2h2o = 2nalo2+3H2 ↑ and heat;
For example, quicklime, sodium carbonate and water react quickly to release heat to provide initial heat, and then heat is released through continuous oxidation of iron powder, aluminum powder and magnesium powder. At this time, the heating bag will make the temperature of water reach above 90 degrees Celsius, and the high-temperature steam generated by it will heat the ingredients, so that the food in the self-heating hot pot is cooked, and it will not harm the human body if used correctly.
