Principle of automatic heating lunch box
You can eat hot meals by putting food in a self-heating lunch box. The reason is that the self-heating lunch box is filled with water bags and non-woven packaging heating agents. There is a small rope on the water bag, which is exposed outside the lunch box. As soon as the rope is pulled, the water bag will break, and the heating agent will react with water to produce high heat, which will heat the food for a period of time. The heating agent is mainly quicklime, and the scientific name is calcium oxide. When lime meets water, it releases heat and produces strong alkali reaction, so you can heat the food by yourself.
Main characteristics of military self-heating lunch box
1, just pour about 100ml of water into the lunch box, and you can enjoy steaming meals in just a few minutes.
2, no open flame, safe and reliable, and it is not limited by place and time when eating.
3. The surface temperature of food can reach about 98℃ after water is poured in.
No matter how clean or dirty the water is, you can heat the food, and the canned food comes with its own water bag.
5. The calories of food can meet the needs of moderate or above military labor intensity.
6. Variety and nutrition are rich, which can meet the different needs of north and south tastes.
7, the weight is enough, each serving can be eaten by 1-2 people at the same time.
8. The special production process of munitions products will never add preservatives.
9. The lunch box can not only heat itself, but also keep warm for more than 3 hours.
10, the heater has the advantages of small volume, high thermal efficiency, long heat generation duration, no environmental pollution and no harm to human body.
How to use the automatic heating lunch box
1. Before heating the lunch box, be sure to open the exhaust cover, because the food in the lunch box will generate steam after heating. If the steam in the heated lunch box increases without opening the exhaust cover, the product will be deformed and cannot be used normally.
2. When the meal is hot, turn on the power, and the power indicator light will be on, and the meal will be hot.
Note: the heating time depends on the amount of food, the degree of heat and cold and the ambient temperature.
① At the ambient temperature of 25℃, the practical effect can be achieved by electrifying at room temperature for about 30 minutes.
② When the ambient temperature is low and the food is refrigerated, the power-on time should be appropriately increased.
③ Unplug the power cord before eating.
