Hot food will raise the surrounding temperature, so the refrigerator must run at high power. Moreover, it will produce water vapor, which is easy to freeze when solidified on the cold plate. When the food shrinks, it will also suck in the odor in the refrigerator, making the food lose its original taste.

The surface temperature of hot objects drops, and the internal temperature changes little, which will breed harmful substances. When you put hot things in the refrigerator, you bring some heat into the refrigerator. The refrigerator needs to cool down and consume electricity, which increases the burden on the refrigerator.

Precautions:

Hot dishes should be sealed with plastic wrap or a covered lunch box as soon as possible, and then put in the refrigerator for refrigeration. It can avoid frosting of condenser tube caused by evaporation of water vapor, prevent bacteria in the air from falling into vegetables and prevent odor.

If the dish is too big, it can't achieve the effect of rapid cooling, and the temperature may not drop for a long time. So it's best to pack it into several copies in advance for storage. If you think you can't finish a meal without the pot, put it in different containers immediately, seal it and put it in the refrigerator, so that the bacteria in the dish are the least.
