How does a hot pot heat up? What is the heating principle of self cooking hot pot?

1. Self-heating hot pot can heat water, but under normal circumstances, cold water is fine. Self-heating hot pot is the principle that the heating bag composed of coke powder, activated carbon and other ingredients can be heated and boiled when exposed to water, so whether it is cold water or hot water, it has no effect.

2. However, in order to avoid scalding, it is best to add cold water, because the heating package of the self-heating hot pot can soar to 96 in one minute, and the temperature will rise faster if you put hot water. Therefore, from the point of view of safety, it is better to use it cautiously according to the instructions. Hello!

The principle of self-heating hot pot:

There is a heating package made of activated carbon, coke powder, quicklime, aluminum powder, iron powder, etc., which will produce a lot of heat after contact with cold water, and the water vapor can be heated for your small hot pot.

How to operate the self-heating hot pot:

1. Open the lid and take out all the ingredients and ingredients. Pour the hot pot base, vermicelli, meat, and vegetables into a small box.

2. Pour warm or cold water into the box, the water can overflow the ingredients, and then stir, stir well.

3. Tear open the bag on the outside of the heating pack, pour cold water into the outer box, and then put the heating bag inside.

4. Put the box with hot pot ingredients into the outer box, close the lid and wait for 15 minutes.

Precautions: 1. The heating package must be placed in cold water before heating.

2. When covering the box lid, you must pay attention to the exhaust hole must be opened.

3. Be careful of hot hands with water vapor and high temperature at the bottom of the outer box.

A hot pot is also a kind of stove, which uses electricity, carbon, and gas. Nowadays, there is more electricity, and the old-fashioned hot pot is burned with charcoal, and the big copper hot pot is filled with carbon inside the hot pot, and after the carbon is drawn, it begins to be heated.

Hot pots, like other heating stoves, rely on heat sources to provide heat energy to heat up. There are many kinds of heat sources, and the main thing is to determine what kind of heat source needs to be used depending on the setting of the pot body.

The hot pot is heated by electricity and heated by natural steam.

It is heated in the same way as any other cooktop.

What is the principle of self-heating hot pot? Why do you get hot so quickly?

When it comes to self-heating hot pot, young people are very familiar with it, it is a kind of fast food, once it is on the market, it has been loved by many people, self-heating hot pot is very convenient to eat, in any place and any occasion, as long as there is water, you can eat steaming self-heating hot pot. In this way, when you are outside, you don't need to eat some other fast food with self-heating hot pot, which is especially suitable for some people who are on a business trip or have difficulty cooking.

The self-heating hot pot contains the ingredients, the heating package and the outer packaging of the self-heating hot pot The principle used to make the substances in the heating package react with the water, and then produce heat, which can make the food in the self-heating pot heated, when using, only need to put the ingredients in the food package in the inner pot of the self-heating hot pot, and then add an appropriate amount of water, and then put the self-heating bag in the outer pot, add a certain amount of water, and put the pot on it, It takes about ten minutes to make a steaming hot pot with the lid on.

Although the self-heating hot pot is very convenient when eating, it is necessary to pay attention to safety, because the substances in the self-heating bag will produce heat if they react with water, once the heat comes into contact with people's **, it may be scalded, sometimes some people eat self-heating hot pot at home, and the natural gas alarm in the home will also remember, mainly because the self-heating package produces some hydrogen, we all know that hydrogen is flammable and explosive, so the use of self-heating hot pot must be on a ventilated and stable tabletop, Avoid the unexpected. After eating the self-heating hot pot, you must pay attention to the handling of the used self-heating bag and the outer packaging of the self-heating hot pot, and do not let the child disturb the self-heating bag to avoid the child eating by mistake, and parents must pay attention.

The principle of self-heating hot pot is to put a packet of activated charcoal underneath, and then heat it to generate heat energy, so you can heat the meal. This is because the activated carbon inside can generate heat when it comes into contact with water, so it heats up very quickly.

Because there is a heating bag in this self-heating hot pot, it is made of quicklime, and after the quicklime and oxygen are together, there is a chemical reaction, and then it will be heated quickly. Because this chemical reaction is relatively fast, the heat generation is relatively fast.

Because there are special substances in the heating pack, it will react with water accordingly, so as to effectively generate heat; Because the heated powder in the heating pack reacts with water, it can be heated quickly.

Because quicklime is placed in the heating bag of the self-heating hot pot, this quicklime will automatically heat up when it encounters water, so it heats up very quickly.

This kind of hot pot is divided into two layers, before eating, you only need to put the ingredients with the base into the upper layer, and then put the heating package composed of coke powder, activated carbon, salt, quicklime, etc. into the lower layer, and add cold water, which can immediately generate heat to heat the ingredients in the upper layer, make the soup boil, and keep it warm for 1 to 2 hours.

Chemical reactions generate heat.

Generally, there are diatomaceous earth, calcium carbonate, aluminum powder, activated carbon, quicklime and other substances to form a heating package, which will produce a high temperature of about 120 150 degrees Celsius when exposed to water, and cook food.

01 First of all, open the package of self-heating hot pot, take out chopsticks, vegetable packets, powder packets, open the middle compartment, and take out the hot pot base packet and heating packet. Open the hot pot base, vegetable packet, and powder packet in turn and put them into a small plastic pot, tear open the plastic bag of the heating bag, put it at the bottom of the pot, and add an appropriate amount of water. Put the top layer of plastic pot on top, cover and wait for the heat, wait for about 15 minutes to open the lid and enjoy the self-heating hot pot.

The detailed heating method of self-heating hot pot is as follows:

1. First of all, we need to remove the packaging of the self-heating hot pot, and then take out the self-heating bag and water.

2. Check whether the lid of the self-heating hot pot is intact to avoid air leakage and heat dissipation during heating.

3. Then empty the bottom of the container of the self-heating hot pot, and put the self-heating heating source and heating bag into the pot.

4. Then pour in the water that promotes the chemical reaction of the heating pack, and add it to the prompt line.

5. Finally, put on the hot pot and dishes, cover and boil.

The heating principle of self-cooking hot pot comes from the heating package inside the packaging box. This heating package is widely used, the main ingredients are sodium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime composed of a bag, injected with cold water, it can be heated to more than 150, and the temperature of steam can reach 200, used to steam food.

Self-heating packs are available in different formulations, but broadly include four types of ingredients.

1.The main thing is quicklime, the scientific name is calcium oxide, which can produce hydrated lime after contact with water, and the scientific name is calcium hydroxide. In this process, a large amount of heat is released, which is the main heat of the heating pack**.

2.Secondly, the heating package contains components such as diatomaceous earth and activated carbon, which are typical adsorbents. Its loose and porous structure is conducive to the adhesion of various active ingredients, full contact and chemical reaction.

3.The heating package usually contains salts such as sodium carbonate, calcium chloride, magnesium sulfate, etc., which are mainly used to absorb the trace amount of water that penetrates into the package, prevent the gradual failure of calcium oxide, and play an auxiliary role in the chemical reaction.

4.In addition, iron and aluminum powders are also commonly found in heating packs, which can release small amounts of heat by reacting with oxygen. It can also form a "galvanic cell" effect with activated carbon, water, and salt, and release heat through redox reactions.

The self-heating pack itself does not come into contact with food, and the ingredients inside are not mysterious, as long as you avoid burns, you can eat it with confidence!

1. The heating package is composed of roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, etc., which will be heated up in 5-10 seconds after cold water, and the high temperature can be maintained at 15-20 minutes, and the food heating hot pot can be reduced to 100, and it can be reduced to 60 after 60 minutes, which can continue to heat the food to about 120 minutes. The whole set of products will not cause any pollution when heated, and there is no potential safety hazard.

2. The lunch box is made of polypropylene, which is a kind of heating plastic resin made by propylene polymerization. Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer, polypropylene has good heat resistance, and is not deformed at 150 degrees under the condition of not being subjected to external forces.

3. This technology is also used in the military equipment of various countries, and the use of this heating package in foreign countries is very wide. Is it safe to use? First of all, the heating pack is not directly connected to the dish, and this technology has been used in military equipment for many years.

During field training, a heating pack is used to cook food. The country's military equipment is very advanced, so a lot of military equipment is very popular in society.

4. There are such products on the market, such as self-heating rice, self-heating canned food, etc.

Our self-cooking technology ** has a heating package with an invention patent. This multi-purpose heating package is mainly composed of sodium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, and quicklime, adding water, the temperature is as high as above, and the steam temperature is up to it, which is used to steam food, and the temperature is kept for 20 minutes and drops after 60 minutes.
