Why do dishes that are put in the refrigerator need to be cooled before putting them, and is it okay

It is not illegal to put hot dishes in the refrigerator, and there is no explicit rule that it is not allowed.

Whether the hot dish is put in the refrigerator immediately or cooled before being put away, the effect is to reduce the temperature from a higher temperature to a lower temperature, the difference is that the time taken to cool down is different.

People, hot and cold, may catch a cold easily. Leftovers are probably not, so don't worry.

Bacteria in the living environment are everywhere, and they are "grabbing" with us every minute, so the sooner the leftovers are cooled, the sooner the reproduction of bacteria will be inhibited to a certain extent.

In this way, hot dishes in the refrigerator have many benefits, so why is it rumored that hot dishes need to be cooled before they can be put in the refrigerator?

To save energy! Objects with higher temperatures enter the refrigerator, and the refrigerator needs to expend extra energy to cool it down. Energy saving is to save money, and saving money is the last word, so this theory has existed for a long time very domineeringly.

Some people say: it will break the refrigerator!

Pull it down, my grandmother's theory from 30 years ago. At that time, the refrigerator was expensive, thinking that if there was something hot in the refrigerator, the compressor would keep spinning, and I would die of exhaustion. This is too insulting to the "IQ" of the refrigerator.

It's okay, you can put it when you want, just weigh the balance between electricity consumption and nourishing bacteria.

It's okay to be hot, but the refrigerator will consume more electricity after putting it hot, and it is easy to make the refrigerator frosty.

The heat in the dish needs to be "carried" out of the refrigerator by using electricity, that is, the hot dish needs to be put into ice to increase the power consumption.

In addition, if the amount is large, the temperature of the refrigerator may rise, and other items will be affected by heat and increase the possibility of deterioration.

Common sense of life. Hot dishes are easy to rot and not easy to keep fresh when put in the refrigerator, as for why, the reason is very complicated, it is just common sense in life.

It is best to put it in the refrigerator when it is hot, as the food is easy to grow and spoil during the drying process.

It's not that it can't, it's just to save electricity and reduce the chance of frosting in the refrigerator. Not necessarily, just advice.

Two, what do you think about the hot dish? It must be the temperature, and when you put it in the refrigerator, it will produce water droplets or ice crystals when it encounters air conditioning, and then attach to the dishes or float into the refrigerator, causing the electricity to burn out or short circuit...

If the hot dishes are put directly into the refrigerator, the dishes are very perishable and easy to spoil, and even affect the shelf life of other foods in the refrigerator.

If you put hot things in the refrigerator, this will substitute some heat into the refrigerator, and the refrigerator needs to work to cool down the temperature, which requires electricity consumption and also increases the burden on the refrigerator.

Generally speaking, after leftovers have cooled, it is best to wrap them in plastic wrap.

Put it in the refrigerator as soon as possible to prevent leftovers from spoiling. The reason why it is wrapped in plastic wrap is because it can avoid moisture in the condenser tube of the refrigerator.

Frosting can also prevent odor transfer.

The temperature of the meal is generally above 90 when it comes out of the pan, and when it drops to 60, bacteria will start to grow, and it is thirty or forty degrees Celsius.

, it is best for bacteria to grow and multiply in large quantities, so it is best to put food in the refrigerator as soon as possible.

Leftovers in the refrigerator is not completely spoiled, this kind of food should not be stored for too long, otherwise it will also spoil, this kind of food is best eaten as soon as possible the next day, otherwise it is easy to cause deterioration, but also increase the reproduction rate of bacteria, speed up the food spoilage process.

Hot dishes should not be placed directly in the refrigerator.

First, after the hot food is put into the refrigerator, the temperature in the refrigerator will be increased, and the working load of the compressor will be increased, resulting in a shorter service life of the compressor and an increase in electricity consumption.

The second is because there are bacteria in the refrigerator, but the activity is not high, and if the hot dishes are put directly in the refrigerator, it will not only increase the temperature of the refrigerator, causing a large number of bacteria and microorganisms to multiply, but also directly expose the meals to the bacterial environment, which is very unsafe.

Common sense in refrigerator use

1. The refrigerator for storing food should not store chemicals at the same time.

2. Do not put bottled liquid drinks into the freezer, so as not to freeze and crack, the packaging bottle should be placed in the refrigerator or on the door, and it is best to store at a temperature of about 4.

3. The food should not be mixed together raw and cooked to maintain hygiene according to the food storage time and temperature requirements, and make reasonable use of the space in the box, do not put the food directly on the surface of the evaporator, but put it in the utensils, so as not to freeze on the evaporator and make it inconvenient to take out.

4. Fresh fish and meat should be sealed in plastic bags, and vegetables and fruits should be dried on the outer surface when stored in the freezer, and put them at the bottom of the refrigerator and refrigerator, and it is advisable to store them at a temperature above zero.

Hot in the refrigerator. When the temperature of the food drops below 60 degrees, the bacteria begin to multiply. The temperature of the food quickly drops to about 7 degrees, and most of the bacteria go into a dormant state.

It is recommended to cover the hot dishes in the refrigerator or rent plastic wrap in the hall, so that the evaporated water vapor of the hot dishes will not affect the condenser tube of the refrigerator. It can prevent various foods from smelling each other. The food taken out of the refrigerator must be heated thoroughly, and the overall heat of the leftovers is to 100 degrees Celsius and keep it for more than 3 minutes.

In this way, most of the bacteria will be destroyed.

1.Hot dishes need to be cooled before they can be put in the refrigerator for refrigeration, because hot dishes will increase the temperature in the refrigerator, which will affect the preservation effect of the food in the refrigerator.

2.At the same time, the water vapor from the hot food in the refrigerator will also condense into water and freeze, making it necessary to clean the refrigerator frequently.

When food is cold, don't put it in the refrigerator. If you want bacteria to multiply more slowly, it's best to put food in the refrigerator while it's still warm. The process of cooling food is actually the fastest process for bacteria to multiply!

Once cooled, place the food in the refrigerator. It's not the food that keeps it fresh, it's the lots of bacteria! Zen: What's the point of this?

Therefore, to achieve the purpose of keeping the food fresh, it is best to put the food in the refrigerator while it is warm. At this time, the bacterial reproduction of food is inhibited by temperature! If you quickly close the lid or put plastic wrap in the refrigerator, the food is the freshest and the nutrient loss is not too great!

Of course, it's best not to eat leftovers! You can cook a little less per meal so that if you eat all the dishes and vegetables from each meal, there will be no problem with leftovers, and you don't have to worry about whether the leftovers will spoil or be nutritious. Nowadays, most families will develop the habit of not having leftovers, and that's right!

After the leftovers are heated twice, the nutrients are basically exhausted, and the human body cannot meet the nutritional needs.

Green leaves. If the leftovers are rice, steamed buns, dumplings, etc. , if it is pork ribs, fish, etc.

There's nothing wrong with saving them for the next meal. Do not heat thoroughly before eating. and green leafy vegetables such as spinach, leeks, rape, etc.

If you can't finish it, it's best to throw it away and don't save it for the next meal! Because there is a substance in green leafy vegetables, this substance can be harmful to the human body after being reheated. Don't let the small be the big!

Gastric cancer. Why is the incidence of gastric cancer high in rural areas? After an investigation by experts, it was found that rural people are very fond of eating leftovers, and they are not stored properly when storing, resulting in a high incidence of stomach cancer!

Therefore, we should place a high value on leftovers. Proper storage is one aspect. It's best not to eat leftovers!

If you want to save food for your next meal, it's best to put it in the fridge while it's hot! This ensures that the bacterial reproduction of leftovers is minimal!

It is recommended to let the dish cool before putting it in the refrigerator.

The refrigeration principle of the refrigerator is "handling temperature", and the temperature of hot food is higher, directly putting it in the refrigerator will affect the temperature in the storage space, increase the load of the refrigerator, and the water vapor emitted by the hot food will condense into water mist, frost, etc. when cold, increase the thickness of the ice layer inside the refrigerator cabin, if it condenses on the surface of the food, it will also affect the taste of the food, but this does not mean that the food containing surface heat can not be put in the refrigerator, but it is not recommended to do so.

Excessive maintenance is a waste, the main role of the refrigerator is to keep fresh and refrigerate food, if you are in a hurry to go out, you can put it in the refrigerator while it is hot, if you have enough time, it is okay to put it in the refrigerator after cooling, it is not recommended and can not be two different things.

Precautions for use of refrigerators

1. Location: The refrigerator should be placed in a cool and ventilated place, avoiding direct sunlight and away from heat sources. When arranging, keep the bottom of the refrigerator stable and avoid tilting.

2. Plug connection: The refrigerator should use an independent power socket, and the plug and socket should be tightly connected to avoid loosening. Attention should be paid to the insulation at the connection between the plug and the power cord to prevent leakage.

3. Food storage: Raw and cooked food should be stored separately in the refrigerator to avoid cross-contamination. Cooked food should be placed on top and raw food should be placed on the bottom. At the same time, food should be arranged closely without leaving gaps to reduce the loss of cold air.

Leave the dish cold and put it in the refrigerator. The temperature in the refrigerator is maintained at about 4, and when something above this temperature is put in, the refrigerator needs to run to lower the temperature, which not only consumes electricity, but also increases the burden on the refrigerator. And if you put something with high temperature in spring, the water will evaporate sharply, forming a frost layer on the evaporator, which will block the evaporator from transferring the heat in the refrigerator to the outside, resulting in a decrease in the service life of the refrigerator.

Notes:Raw meat, seafood, eggs and other food raw materials are not recommended to be left at room temperature for more than 2 hours. If it is hot and the temperature is above 32, this time must be shorter, i.e. it must be put in the refrigerator earlier.
