What is the temperature of boiling water in a pressure cooker?

Speaking of boiling water, I believe everyone knows that this is water that has reached its boiling point. Under normal circumstances, the boiling point of boiling water is 100℃ and under normal atmospheric pressure, the highest temperature of water can only reach 100℃. In people's daily life, there are also cases where people use pressure cookers to boil water. Because of its unique function, the pressure cooker can make the air pressure inside the pot higher than the normal atmospheric pressure, so the boiling water temperature will become higher. So what is the boiling water in the pressure cooker?

What is the boiling temperature of water in a pressure cooker?

A pressure cooker, also known as a pressure cooker, can heat food to over 100°C, specifically 111°C to 122°C. Its unique high temperature and high pressure functions greatly shorten the cooking time and save energy. However, a pressure cooker with high working pressure can also cause great damage to nutrition. Currently there are four types of pressure cookers: ordinary aluminum alloy pressure cookers, stainless steel composite bottom aluminum alloy pressure cookers, stainless steel pressure cookers, and electric pressure cookers.

The principle of the pressure cooker is very simple. It is designed based on the principle that the boiling point of water is affected by air pressure. The higher the air pressure, the higher the boiling point. The pressure cooker seals up the water quite tightly. When the water evaporates due to heat, the generated water vapor cannot diffuse into the air and can only remain in the pressure cooker. This makes the air pressure inside the pressure cooker higher than 1 atmosphere, and the water will boil only at a temperature higher than 100°C. This creates a high temperature and high pressure environment inside the pressure cooker, making it easy to cook rice quickly. Of course, the pressure in the pressure cooker cannot be unlimited, otherwise it will become a bomb.

Notes on using a pressure cooker:

1 Before each use, carefully check whether the exhaust hole of the pressure limiting valve is unobstructed and keep the anti-blocking cover clean;

2 Do not fill the pot too full with food, generally it should not exceed three quarters of the height of the pot. For foods that expand easily, the amount should not exceed half of the pot;

3 When closing the lid, align the closing marks on the lid and the pot body and make sure they fit completely. Stop when it is in place, don't use too much force to turn it over;

4. After heating, close the cover and close the pressure limiting valve cover when more steam is seen to be discharged from the pressure limiting exhaust hole;

5. When the pressure limiting valve is working, reduce the fire power to keep the pressure valve moving slightly;

6 Before opening the cover, you must wait until the pressure is completely reduced, that is, the valve core of the protective device drops and resets before you can open the cover. The handle cannot be forced;

7. The usage period should not exceed the safe service life specified for general pressure cookers.
