The difference between a steamer and a thermos
The duration of the heat preservation is different
The thermal insulation principle of these two kinds of kettles is the same, and the difference between the thermal insulation kettle and the stewed kettle is mainly reflected in the difference in thermal insulation effect and material between the two.
Under normal circumstances, the thermal insulation effect of the thermos can keep the cold drink in the bottle at about 4 degrees Celsius and the boiling water at about 60 degrees Celsius within 12 hours.
The simmering pot is better at keeping warm than the thermos pot. After the pot is poured into hot (ice) water, the shell does not sweat, and the heat preservation (ice) effect can reach more than 24 hours.
Different manufacturing materials
The outer shell of the thermos is generally made of bamboo, plastic, iron, aluminum, stainless steel and other materials. Rubber gasket, there is a bowl-shaped rubber seat at the bottom of the bottle, these are used to fix the glass bladder to prevent it from colliding with the shell.
The thermal insulation material of the stew pot is also better than that of the general thermal pot, which is made of high-quality stainless steel. So it can have a “simmering” effect, which means that the food can maintain the temperature just poured into the bottle for several hours.
Which is better, stew pot or thermos pot
1, the first Round: Appearance
At first glance, there is no big difference between a simmering pot and a thermos pot. They are based on the same principle, which is a derivative of Sir James Dewar’s 1982 study on insulating heat transfer, and the design of the vacuum in the middle of the double shell is the same. But if you have to say that you are ugly, the stew pot is slightly smaller than the thermal insulation pot in appearance. In the first round, the simmering pot seemed to be at a disadvantage.
2, second round: function
in first round Compared with the thermal insulation pot, the simmering pot suffers in size, but when it comes to functions, the simmering pot is definitely not worse than the thermal insulation pot! The thermal insulation pot relies on nothing more than the constant temperature for a long time, but in this aspect, the stew pot is obviously better than the thermal insulation pot in terms of the insulation time and the insulation effect, not only the insulation time is doubled, but also from morning to afternoon. can be kept within a small temperature difference. In addition, the simmering pot also has a skill that the thermal insulation pot does not have, and the simmering pot is also named after this skill, that is, by keeping the temperature in the pot at a high temperature, so that the pot is originally undercooked. The ingredients are simmered and cooked at high temperature. In the second round of the contest on functions, the performance of the simmering pot was really outstanding, and it recovered the defeat in the first round and won a big victory.
3, the third round: performance
Compared with all aspects, the overall performance is undoubtedly better One chip. Looking at the function of the thermal pot only to maintain the temperature, and it seems to be inferior to the stew pot. The simmering pot not only has an excellent heat preservation function, but also has a nirvana that cooks raw food hard by relying on the heat preservation function. This skill can save us a lot of energy, such as electricity and gas, which is in line with the current concept of environmental protection. In the third round of the comprehensive performance contest, the simmering pot that is environmentally friendly, energy-saving and has outstanding functions is better.
What should I do if the stew pot does not keep warm
The stew pot with good thermal insulation effect, after pouring hot water into the stew pot, the shell does not sweat, The heat preservation effect can reach more than 24 hours. If the simmering pot is not insulated, and the shell heats up quickly after pouring hot water, it means that the vacuum layer is leaking, and the simmering pot cannot be repaired without heat preservation.
