Main ingredients: sodium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime.

These ingredients are combined into a bag, and water is added to trigger the reaction. The function of this fireless heating is to use the heat-releasing chemical reaction of calcium oxide in lime when it meets water, release heat energy and generate steam, thereby cooking food. The temperature can be as high as 150 degrees or more, and the steam temperature can reach 200 degrees. The stingy hole on the fireless hot pot lid is used to drain the water vapor in the box.

The following heating bag manufacturers introduce you to the use of self-heating hot pot on the market:

1. Put the hot pot base into the bottom of the upper lunch box.

2. Put in vermicelli. Vermicelli and other ingredients need to be cooked longer than other ingredients, so they must be placed on the upper layer of the base, because they are close to the heating bag and are easy to cook soft. Close to the base, it is easy to taste.

3. Add vegetables.

4. Add the meat bag.

5. After the ingredients are finished, add an appropriate amount of drinking cold water to the lunch box. The amount of water should be enough to cover all the vermicelli. Babies who like more soup can add a little more water, but don’t exceed the water level line above the lunch box! !

6. Open the wrapping paper of the heating pack and put the heating pack into a special lower box.

7. Add an appropriate amount of cold water, which must be cold water. The amount of water should be just enough to cover the heating pack. If there is less water, the heating time will be insufficient, and if there is more water, the heating process will overflow.

8. Put the lunch box with the ingredients in it into the bottom box.

9. Cover the lid, the heating pack starts to heat up, and the small hot pot will start to boil. The heating time is more suitable for 20 minutes. Be careful not to heat it directly on the glass tabletop! !

10. After 20 minutes, the fragrance has overflowed. Open the lid, add sesame oil and mix well, and you can start to enjoy it.
