How to use the heating pack, how to use the heating pack correctly

When using the heating bag in the self-heating hot pot, first put the food into the upper lunch box, then put the heating bag into the lower lunch box, add an appropriate amount of cold water, and place the upper lunch box. When pouring cold water, it is advisable to use the amount of water that does not pass through the heating pack to avoid excessive water splashing during the heating process.

The main ingredients in the heating package are sodium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, and quicklime.

Quicklime: The scientific name is calcium oxide, which will release a large amount of heat after chemical reaction with water and turn into calcium hydroxide. The process of quicklime encountering water is the main heat in the heating package.

Diatomaceous earth and activated carbon: Roasted diatomaceous earth and activated carbon are typical adsorbents in chemical agents, and their loose and porous structure makes them conducive to the adhesion of various active ingredients, so as to achieve full contact with water and chemical reaction.

Sodium carbonate and calcium chloride: Sodium carbonate and calcium chloride are chemical salts that can absorb trace amounts of water deep into the heating pack, preventing quicklime from failing during the reaction.

Iron powder and aluminum powder: Reacting with oxygen will release a little heat, and form a "galvanic cell" effect with activated carbon, water and salt to achieve continuous heating of the ingredients.

When the heating pack is used, the heat released can be as high as 150 degrees. Do not touch it at this time to avoid being burned.

1 First open the outer packaging of the lunch box, put the heating bag in the box, then put the food and seasonings in another lunch box, add cold water to the box where the heating bag is located, put the food box on the heating bag, cover the lid and wait for about 10 minutes, and the food is completed. Keep in mind that you can't heat the water here, it will cause high temperatures, and the water will boil violently, which is dangerous, so you should strictly follow the steps.

2 When heating, the outside of the lunch box will continue to be hot, do not touch it with your hands, and do not put it on the glass, because the lunch box is very hot after heating, which is easy to cause the glass surface to burst. If it is a wooden table, it is easy to leave some marks and marks on the table surface. spoils the essence of the table, and also affects the aesthetics.

3 After normal heating, be careful when lifting the lid to avoid being scalded by steam. Because the temperature at this time is very high, it is able to cook the vermicelli. It is very important that self-heating lunch boxes should not be placed in the microwave or in the oven.

Therefore, safety is of paramount importance when eating self-heating food.

FeverThe proper use of the package is as follows:

First open the bag and add hot water, and then a chemical reaction will occur.

Put the matching partition layer that needs to be heated, wait for about ten minutes, and then it will be heated, and then open the lid to eat.

1. Unpacking. Place self-heating rice.

Open the box, take out the heating pack, water, vegetables and rice, unpack the heating pack, and put it at the bottom of the box. Rice and vegetables are placed in the upper partition box.

2. Add water. After putting in the heating pack, add the water that promotes heating, using tap water or the water provided in the original package, and then put the rice compartment box that needs to be heated.

3. Heating. Cover and start heating the rice and dishes. It is estimated that the heating reaction will take about 10 minutes to complete.

4. After the heat dissipation is completed, the lid can be opened, and the heat can be dissipated to a suitable temperature, and it can be eaten.

The whole process is actually very simple, the only thing to note is that during the operation, the temperature will rise quickly due to the chemical reaction, use it with care and don't burn it.

When using the food heating bag, tear off the OPP film first, place the heating bag in the high-temperature box, add a certain amount of room temperature water, prohibit the use of hot water, it will slowly heat the water.

Note: When heated, the temperature at the bottom of the package is extremely high, so it should not be placed on the glass to prevent the glass from breaking or leaving marks on the tabletop; When heating is complete, be careful when removing the lid to avoid burning your hands with steam.

The heating package, that is, the special heating package for food, is composed of self-heating materials packaged by non-woven fabrics and OPP films. When using, you only need to tear off the OPP plastic film, place it in a high-temperature box, and operate and use it according to the specific use method.

With the continuous improvement of consumption level and the acceleration of the pace of life, today's self-heating food has derived many categories such as self-heating rice, self-heating hot pot, self-heating vermicelli, self-heating noodles, self-heating snail noodles, and self-heating vegetables. The heating pack is one of the items that can achieve the self-heating condition of self-heating food.

The heating package (also known as the food heating package) is a self-heating material (the main components are calcium oxide, sodium bicarbonate, etc.) sealed and packaged by non-woven fabrics, and finally through the OPP film (the whole package is composed.

The components of the heating package have different formulas, generally speaking, the main components are quicklime, activated carbon, iron powder, aluminum powder and other ingredients, generally speaking, the heating package is relying on quicklime and water contact, releasing a large amount of heat. Generally speaking, the heating pack cannot be used again after it has been used.

During the use of the heating pack, it is not recommended to put it on ordinary glass, which may cause the glass to break. During the use of the heating bag, be sure to open the ventilation hole to discharge the hot air, which can reduce the small ** caused by excessive pressure in the box.

The heating pack must be eaten on a level level to prevent chemicals from escaping inside.

In addition to the heating package used in the self-heating pot, the warm baby is also a kind of heating bag, this kind of heating package will not heat up without tearing off the adhesive, because the warm baby without tearing the package, the substances inside cannot react with the air, so the warm baby has no way to get hot.

The main function of iron powder is to react with oxygen in the air to produce iron oxide, so that after the iron is corroded, it will release heat, which will make the temperature of iron powder rise instantaneously.

Baby warmers generally use porous pouches, and if you open the plastic bag, air will seep into the pouch.

The heating package is made of roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime, sodium carbonate and other materials. The main ingredient is quicklime, the scientific name of calcium oxide, which can produce hydrated lime when it comes into contact with water, and in the process it releases a large amount of heat, which releases heat energy and produces water vapor, which meets the standard of cooking food.

1. One box of self-heating rice and unpack. Remove the rice packet from the self-heating rice.

2. Use the top of the self-contained spoon to cut open the outer packaging of the rice packet.

3. Then the self-heating rice is disassembled, and then we use a spoon to mix the rice to make it soft.

4. Put the heating bag into the plastic box at the bottom of the self-heating rice, and add a certain amount of mineral water. Wait after putting the rice back in place.

5. Cover the outer packaging shell and wait for the heating bag to heat up. There is a gurgling sound when you have a fever, so be careful not to touch it with your hands to avoid burns.

6. Finally, put the vegetable bag under the self-heating rice lunch box and heat the vegetable bag as well.

7. When it has cooled completely, tear off the shell and enjoy the hot rice.

When using the heating package, first tear off the OPP plastic film, place the heating package in the high-temperature box, add a certain amount of room temperature water, prohibit the use of hot water, and then use the heat generated by the water vapor (non-toxic and harmless) generated by the reaction between the heating package and water to heat the food. Pay attention to use the compartment to separate the food from the food when using the heating pack, and do not come into direct contact with the food.

The heating package is a special heating package for food, which is composed of self-heating materials (the main components are calcium oxide, sodium bicarbonate, etc.) sealed and packaged by non-woven fabrics, and finally packaged by OPP film.

The heating bag is one of the items that can achieve the self-heating conditions of self-heating food, and the common self-heating foods include self-heating rice, self-heating hot pot, self-heating vermicelli, self-heating noodles, sail lack of self-heating snail noodles, self-heating vegetables, etc.
