Can I put water into a thermos cup and put it in the refrigerator for quick freezing? Will the thermos cup be damaged?
See what kind of thermos cup it is.
After water is frozen into ice, the more it freezes, the more it expands, and the glass will burst. Metal cups are better, and generally they will not break. However, the heat transfer of the thermos cup is poor, and the freezing speed is slow, so the purpose of quick freezing cannot be achieved. Better to use another container.
Can the thermos cup be stored in the refrigerator?
It is not recommended to put the thermos cup in the refrigerator. The biggest use of the thermos cup is to prevent the loss of heat energy, and the temperature of the water in the thermos cup cannot be lowered even if it is placed in the refrigerator. The principle of the thermos cup is the same as that of the boiling water bottle. It uses the principle of vacuum to prevent cold air from entering the hot water. Putting the thermos cup in the refrigerator for a long time will affect the insulation effect of the cup and affect the service life of the refrigerator and the cup.
Will the stainless steel thermos cup be broken in the refrigerator?
meeting. Put the thermos cup into the refrigerator to freeze. In fact, doing so will greatly damage the original structure of the thermos cup, and it will easily cause distortion. If there is a problem with the vacuum layer, the heat preservation effect will be greatly weakened. The main purpose of the thermos cup is to prevent heat dissipation and provide considerable protection against thermal expansion. If the thermos cup is placed in the refrigerator to freeze, it will be affected by the cold shrinkage, and the thermos cup will not be able to withstand the cold pressure, which will cause the inner structure of the thermos cup to bend. Deformation makes the thermos cup unable to exert its thermal insulation performance. In addition, the thermos cup is to delay heat convection, even if it is to be frozen, the temperature should not be too low, and at the same time, the cover should be unscrewed or loosened.
Although the thermos cup has the ability to resist falling, compressing, heat, and cold, if it is not used properly, even the imported brand thermos cup will destroy its own characteristics. For example, the cup cover is made of plastic, which can prevent heat conduction. The vacuum layer has the effect of preventing thermal contact and cooling.
Finally, when using the thermos cup, first understand how to use the thermos cup. Do not put the thermos cup in the refrigerator to freeze, but use it reasonably.
Can thermos cups be stored in the refrigerator? Can warm things be stored in the refrigerator?
Put the thermos cup in the refrigerator, from a safety point of view, there will be no potential safety hazards. However, from a practical point of view, there is almost no cooling effect. The function of the thermos cup is to keep the temperature of the water in the cup, so it can achieve the effect of heat insulation. If the lid is tightly closed and put in the refrigerator, of course it will have no effect. If you just want to cool, you can use a thermos cup to hold water without covering the lid, but this is very unsanitary, and the refrigerated water may have a peculiar smell.
Warm things can be stored in the refrigerator. It’s just that it takes longer to achieve the effect than putting it in cold, and it consumes more electricity and consumes more of the refrigerator. If you are in a hurry to refrigerate, of course you can put warm things in the refrigerator, but if you are not in a hurry, from the perspective of energy saving, it is recommended to let things cool before putting them in the refrigerator.
Can the thermos cup be stored in the refrigerator?
Do not put the thermos in the refrigerator when there is water in it, and put it in the refrigerator when it is empty.
The biggest use of the thermos is to prevent heat loss, and the temperature of the water in the thermos cannot be dissipated even if it is placed in the refrigerator. The principle of the thermos cup is the same as that of the boiling water bottle. The principle of vacuum is used to prevent cold air from entering the hot water. Putting the thermos cup in the refrigerator for a long time will affect the insulation effect of the cup, so it is not recommended to put the thermos cup in the refrigerator.
There should be no liquid water in the thermos. The volume of liquid water will expand when it freezes, which may damage the thermos bottle. The temperature of the thermos bottle made of glass cannot change sharply. For example, if a hot bottle suddenly cools down, it may burst. How long it takes to thaw depends on the temperature of the environment (generally refers to the temperature set by the refrigerator). If the temperature is higher, it will be faster, and if the temperature is lower, it will be slower.
It is not recommended to put juice in the thermos bottle. The airtight environment of the thermos cup is more conducive to the growth of bacteria. Putting in juice, the thermos cup will soon be occupied by bacteria. Juice is recommended to be squeezed and drunk immediately, try to drink it within 1 hour, because the bacteria will increase in size and metabolism will be active after the juice is stored for 1-4 hours, and it is easy to produce toxic metabolites, and the number of bacteria will increase logarithmically in 6-8 hours. into a mass breeding period.
If watermelon juice and other juices need to be stored, it is recommended to refrigerate them as soon as possible, but refrigeration can only inhibit the reproduction of bacteria, but cannot freeze pathogenic bacteria to death, and even some germs can still reproduce and grow in the refrigerator.
