Why don t you freeze your hands at all when you take out the steamed buns in the freezer compartment

Because it is a bad conductor of heat. The heat conductivity is slow, and the heat conduction of the hand is lost slowly, so the amount is not felt.

If it's metal, it's miserable. The skin of the steamed bun is evaporated in the high temperature heating, forming a very chewy skin, precisely because the skin has no water, and as we all know, ice is the solid state of water, so there is no water in the freezer and it will not be involved to form ice, so it will not feel cold when you take it out.

In the same way, popcorn and the like don't feel cold when you put it in, but the temperature inside is definitely not high, and if you want to eat it, you still need to let it stand for a while, otherwise your stomach will hurt easily

The main thing is that the steamed bread has less moisture, and it does not freeze when frozen, and it is not cold if it is not frozen, and if it is packed in a plastic bag, it will feel just hard, although it is minus 18 degrees.

Manju is also a bad conductor of heat, and when taken out of the freezer compartment of the refrigerator, although the temperature is very low, it will absorb heat from the hand when it comes into contact with the hand. But the heat is not transferred quickly, the hand does not lose too much heat, and the temperature of the hand decreases only slightly. In the same way, re-steam the cold steamed buns, sometimes, the outside is steamed hot, and the inside is still cold (the feel is soft on the outside and the inside).

On the other hand, the steamed steamed buns, after a little drying, are not hot on the outside, and it is still very hot on the inside when broken, even hot mouth. Some people eat sugar triangle and are burned by sugar, of course, it has the effect of sugar coagulation and exothermy, but the temperature of sugar is still very high is also an important reason.

The heat transfer of people in contact with steamed bread mainly depends on the conduction mode, that is, the heat is transferred along the object. Different objects have different abilities to conduct heat, according to which objects are classified as good conductors of heat and bad conductors of heat. For example, metals are good conductors of heat, and plastics, rubber, paper, wood, etc. are all bad conductors of heat.

Put the metal spoon head in the hot soup and the handle will quickly burn your hands, while the wooden chopsticks will not burn your hands when you put them in the hot soup.

Because the temperature in the room is much hotter than in the freezer.

This is because the temperature of the freezer is not low enough.

The phenomenon caused by insufficient temperature in the refrigerator.

The temperature of the freezer is not low enough.

Because the refrigerator temperature is not enough.

If the temperature is too low, the steamed buns will freeze your hands.

He's just hardened, but there's ice in it.

It may be that there is less moisture in the steamed buns.

Summary. This situation is mainly because the humidity in the refrigerator is large, and the surface temperature of the evaporator on the wall of the refrigerator is very low when working, so the moisture in the air in the refrigerator will gather on the back of the refrigerator and condense into ice beans or frost, when the refrigerator stops working, due to the rise in the temperature of the refrigerator, the ice beans or frost can be turned into water and flow out from the water outlet, so this phenomenon is normal. In summer, due to the high air temperature and humidity, the frost or ice beans in the refrigerator will be relatively heavy.

In order to reduce frosting and icing beans in your refrigerator, please pay attention to the following points in use: 1) Minimize the number and time of opening the refrigerator. 2) After the refrigerator is closed, be sure to check whether the door is closed tightly to prevent air leakage from the door seal.

3) There should be a certain gap for food in the refrigerator, especially the food should not be close to the back wall of the refrigerated liner. 4) Try not to place food with a lot of moisture in the refrigerator, and if you do want to place it, it is best to seal it with plastic wrap. 5) Pay attention to whether the drain is blocked by dirt, if it is blocked, dredge it with a perforated pin or other similar plastic rod.

In addition, if the refrigerator with a low temperature compensation switch is used when the ambient temperature is relatively high, the operating time of the refrigerator will be relatively longer.

This situation is mainly due to the high humidity in the refrigerator room, and the surface temperature of the evaporator on the wall of the refrigerator room is very low during work, so the moisture in the air in the refrigerator room will gather on the back of the refrigerator room and condense into ice beans or state leakage frost, when the refrigerator stops working, due to the rise in the temperature of the refrigerator room, the ice beans or frost can be turned into water and flow out from the water outlet, so this phenomenon is normal.
