The heat source technology of the self-cooked chafing dish comes from the patented heating bag. This small heating bag contains iron powder, aluminum powder, calcium oxide, coke powder, activated carbon and quicklime, and when they contact with water, chemical reactions will occur. The main reaction principles involved are: CaO+H2O=Ca(OH)2 and a lot of heat 2al+2NaOH+2H2O = 2NALO2+3H2.
for example, quicklime, sodium carbonate and water react quickly to release heat, providing initial heat, and then the 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 9 degrees Celsius, and the high-temperature steam generated by it will heat the food in the self-heating chafing dish, so that the food in the chafing dish is cooked thoroughly, and it is not harmful to the human body if used correctly.
