Self heating food refers to pre packaged food that does not rely on heating methods such as electricity or fire, but is heated using a built-in heating bag.
When in use, simply place the specially made heating bag at the bottom of the food box and a cup of cold water to make steaming food.
Self heating food comes with a heating package, which increases in temperature when encountering water. The heating package is mainly composed of materials such as iron powder, aluminum powder, coke, activated carbon, and quicklime. By adding cold water for reaction, the temperature can reach 150 ℃ after heating, and the steam temperature can reach 200 ℃. The longest insulation time can be maintained for three hours. If an accident occurs, it can easily cause burns and other hazards.
Self heating food heats products through chemical reactions, and its safety cannot be guaranteed, and the industry lacks national standards.
1. During use, be careful not to let hot water flow out. Heat evenly every 3-5 minutes and be careful of steam burns, as the temperature can reach around 98 degrees Celsius during heating.
2. After the reaction, the heating treasure can be placed in an insulation paper bucket to make two heating treasures to warm up. Fold the mouth well and continuously release 2.8 to 3 hours of heat.
