Self-heating chafing dish heats food through the reaction between the lower heating bag and water, and this heating bag will quickly heat up and boil when it meets cold water, providing heat source for the upper food. The correct operation steps are: spread a heating bag on the lower floor and add a proper amount of cold water according to the instructions.

After adding water, wait for the heating package to heat up and start working (usually a lot of steam and heat will be generated in a few minutes). Put the ingredients and seasonings into the upper container, without adding extra hot water or cold water, and the heat generated from the lower layer will be conducted to the upper layer to cook the ingredients. In the self-heating pot, heating water is not needed or recommended in the upper food area, and food is cooked by the heat generated by the reaction between the lower heating bag and cold water.
