Why do you put hot things in the refrigerator when they are cold?

Reasons why hot things should be put in the refrigerator when they are cold:

1. Dishes that are too hot cannot be put directly in the refrigerator. The refrigerator itself is an enclosed space, and the temperature of the dishes itself is not necessarily lower than the cooling rate inside the refrigerator when there is air circulation outside. Background:

Most refrigerators in China are directly cooled, and refrigeration is transmitted naturally. The refrigeration speed of air-cooled refrigerators is significantly better than that of direct-cooled refrigerators, which is also the reason for the wind (circulation). Refrigerators are designed based on certain design standards, and most of the domestic climate types are ST type.

18 38, that is, the maximum ambient temperature of 38 degrees Celsius, the refrigerator can operate normally, and the test standard is also room temperature things put in. If you suddenly put in a lot of overheated food, it will exceed this design standard.

2. Changing the temperature inside the refrigerator will affect the storage of other foods. For example, if you suddenly put very hot food in the refrigerator at minus 18, the surrounding temperature will definitely increase a lot, so it is possible that other foods around you are lower than the storage temperature. For example, the storage temperature requirement of high-end ice cream with high milk content is much lower than 0.

3. Damage to the refrigerator refrigeration system: Due to the low temperature in the refrigerator, when the hot food is cold, the moisture contained in it will evaporate sharply and then solidify on the internal evaporator, and a thick frost layer can be formed on the evaporator in a short time. This prevents the evaporator from transferring heat from the inside of the refrigerator to the outside.

The refrigeration effect is affected. At the same time, the thermostat probe is also wrapped in a frost layer, which cannot detect the temperature in the box, so that the compressor stops working. As a result, it cannot be refrigerated.

Only after the frost layer has melted can the compressor work again. The increase in power consumption is obvious.

Hello! There are a few reasons why hot stuff shouldn't be put in the fridge:

1 The inside of the refrigerator should be maintained at about 4 degrees so that the food stored in the refrigerator can last for a long time. When you put something hot in the fridge, the temperature in the fridge will rise. Then you don't meet the condition that "the inside of the refrigerator should be maintained at about 4 degrees".

In this way, the food stored in the refrigerator is prone to spoilage.

2 When you put something hot in the refrigerator, you bring some heat into the refrigerator, and the refrigerator needs to increase the workload to bring the temperature down, which consumes electricity and also increases the burden on the refrigerator.

3 Because the surface temperature of a hot object drops quickly, but the temperature inside drops more slowly, bacteria can grow in this process.

4 Hot food will raise the temperature around you, and the refrigerator will have to run at high power. In addition, it will produce water vapor, which will freeze easily when solidified on the cold plate, and the food will also inhale the odor in the refrigerator when it shrinks.

Reduce the temperature difference, if you put the hot one in the refrigerator, then the original things around him will be affected to a certain extent, and the temperature will rise suddenly, that is, it will not have the ability to freeze temporarily. In addition, it will suddenly put pressure on the refrigerator, which can be regarded as improper use!

Generally above 60, the vast majority of bacteria cannot survive, while below 4, bacterial proliferation is significantly slow. If you choose to let the hot food cool before putting it in the refrigerator, when the meal drops to 60, the bacteria will start to multiply, and the longer it is left at room temperature, the more bacteria will multiply.

The World Health Organization recommends that cooked food should not be stored at room temperature for more than 2 hours, and all cooked food should be refrigerated in a timely manner.

So, the shorter the time before the meal goes to the refrigerator, the better. Leave it at room temperature for one more minute and it's dangerous.

The refrigerator is easy to break, because the refrigerator generally has a freezing layer and a fresh-keeping layer, and the refrigerator operates according to the temperature of the box, such as putting hot objects will make it unbalanced, thereby shortening the service life.

If the amount is not too much, it will not affect too much, because the heat will always be dissipated, and there is no need to consume electricity outside, and the pressure of the Xiaoice box will be reduced.

Try not to put hot things in the refrigerator.

Generally speaking, it is not recommended to put hot things in the refrigerator, because hot things in the slow beat of refrigeration require the refrigerator to take more time to take away the heat, which will increase the burden on the refrigerator, and often this is easy to increase energy consumption, so it is best to wait until the thing is cold before putting it in the refrigerator.

And putting hot stuff in the freezer will increase the overall temperature of the refrigerator, which can cause some bacteria in the freezer to start multiply, increasing the chances of other foods being contaminated.

Precautions for storing items in the refrigerator

1. Pay attention to classified storage: meat, vegetables, condiments, etc. need to be stored separately, and fresh meat and frozen meat should also be stored separately.

2. Pay attention to the refrigeration period: many foods have their own refrigeration period, and the refrigeration period is mainly determined by the optimal storage temperature of the food itself.

3. Pay attention to the separation of raw and cooked food: raw food is often stained with germs, parasite eggs and other dirt. If raw and cooked food are put together, the bacteria on the raw food will quickly contaminate the cooked food, which is not good for human health. Therefore, raw and cooked foods should be stored separately.

4. Be careful not to overfill: don't put the refrigerated food too densely, leaving a gap will be beneficial to the cold air circulation, so that the food cools down faster, reduces the number of times the compressor runs, and saves electricity.

Here are some reasons why hot stuff can't be put in the refrigerator:

1.Food leakage is easy to spoil: Putting hot things in the refrigerator will cause the temperature in the refrigerator to rise, affecting the preservation of food, and easily causing food to spoil.

3.Breeding of harmful substances: Putting hot things in the refrigerator will change slowly, which is easy to breed bacteria and harmful substances, affecting the quality and safety of food.

Therefore, in order to avoid the above problems, it is recommended to wait for the food to cool down before putting it in the refrigerator.

Hot things should not be put in the refrigerator right away, as this will raise the temperature inside the refrigerator and cause the quality of other foods to suffer. In addition, hot food will produce a lot of water vapor when it is placed in the refrigerator, which will lead to an increase in humidity inside the refrigerator, which will increase the possibility of bacterial growth. The best course of action is to leave hot food at room temperature and allow it to cool naturally to room temperature before putting it in the refrigerator. Swift Sky.

5. Due to the low temperature in the refrigerator, when the hot food is cold, the moisture contained in it will evaporate sharply and then solidify on the internal evaporator, and a thick frost layer can be formed on the evaporator in a short time, blocking the evaporator from transferring the heat in the refrigerator to the outside. Thus reducing the service life of the refrigerator.

Placing hot stuff directly into the refrigerator may negatively affect the performance of the refrigerator and may affect the preservation of the food detached in other refrigerators. Here are some reasons why hot stuff shouldn't be put straight in the fridge:

1.Damage to the refrigeration system: Putting hot food directly into the refrigerator can cause the temperature inside the refrigerator to rise rapidly, which can damage the refrigerator's refrigeration system. The refrigerator takes longer to re-reach the set temperature, wasting electricity.

2.Affect other foods: Hot food can increase the temperature inside the refrigerator, which can affect the freshness of other foods. This can lead to premature spoilage of food, affecting the taste and nutritional value of the food.

3.Increase refrigerator noise: Placing hot food directly into the refrigerator may cause temperature fluctuations inside the refrigerator, which can increase the noise of the refrigerator. This noise may affect your daily life and rest.

4.Reduced refrigerator life: Putting hot food in the freezer frequently may shorten the life of the refrigerator. This is because frequent temperature fluctuations can lead to fatigue and damage to the internal parts of the refrigerator.

To ensure the performance of your refrigerator and the freshness of other foods, it is recommended that you allow hot food to cool until it is warm before putting it in the freezer. You can place the food in a large bowl, add some ice cubes and water, and place the bowl in a cool, ventilated place to let the food cool gradually. This ensures that the food has been cooled before being placed in the refrigerator and reduces the impact on the performance of the refrigerator.

There are several reasons why hot food cannot be put in the refrigerator: first, putting hot food in the refrigerator will cause the temperature of the refrigerator to rise, which will accelerate the deterioration of other food in the future1; Secondly, when you put hot things in the refrigerator, you will bring some heat in, increase the burden on the refrigerator, and increase power consumption2; In addition, when hot food is cold, the moisture contained in it will evaporate sharply and then solidify on the internal evaporator, preventing the evaporator from transferring heat from the refrigerator to the outside, which will affect the service life of the refrigerator to a certain extent3. Therefore, in order to ensure the storage of food and the normal use of the ice cover box, we should first cool down the hot food before putting it in the refrigerator.

Allow the food to cool naturally before storing it in the refrigerator for a longer period of time. Instead, you can't put hot food sources directly in the refrigerator. So why can't you put it in directly?

For this problem, the main reasons for this problem are 4 points, you can take a look. In fact, there are two main aspects to consider this problem: the first is the impact on food, and the second is the impact on the refrigerator itself.

If you put hot food into the refrigerator, it will be able to damage the refrigerator, because in the repeated refrigeration process, the refrigerator will run faster and the refrigeration speed will be accelerated, so the service life of the refrigerator will be faster.

Try not to put hot food directly in the refrigerator, wait for it to cool to room temperature before putting it in the refrigerator.

There are three reasons why:

1.The inside of the refrigerator should be maintained at about 4 so that the food stored in the refrigerator can last for a long time. If you put hot things directly into the refrigerator, the temperature in the refrigerator will rise, and the condition of "the inside of the refrigerator should be maintained at about 4", and the food stored in the refrigerator is easy to spoil.

2.When something hot is put into the refrigerator, some heat is brought into the refrigerator, and the refrigerator needs to work to bring the temperature down, which consumes electricity and also increases the burden on the refrigerator, which will reduce the lifespan.

3.Due to the low temperature in the refrigerator, when the hot food is cold, the moisture contained in it will evaporate sharply and then solidify on the internal evaporator, which can form a thick frost layer on the evaporator in a short time, blocking the evaporator from transferring the heat in the refrigerator to the outside.

If you follow the refrigerator instruction manual, it will definitely not work. However, put a cup of hot water and a cup of cold water of the same quality in the refrigerator at the same time, and the hot water freezes first. You can try.
