How to deflate the pressure cooker?

Degassing method:After cooking, it can be cooled naturally at room temperature, if you want to eat immediately, you can use forced cooling method (i.e., drenching with water or immersing in water) to reduce the pressure, after cooling, you can gently put out the restrictor valve, and release the remaining gas.

See the exhaust pipe no vapor discharge, the float falls, you can open the lid in the counterclockwise direction. If the float does not fall, it proves that there is still pressure in the pot, then the air pressure interlocking device will play an insurance role, and it is impossible to open the lid, do not force to open the lid. You should use chopsticks to press down on the indicator valve, so that the remaining air in the pot can be discharged, before opening the lid.

Pressure cooker working principle

Pressure cooker principle is very simple, because the boiling point of the water is affected by the air pressure, the higher the air pressure, the higher the boiling point. In the mountains, plateau, air pressure less than 1 atmospheric pressure, less than 100 ℃ water can boil, eggs with ordinary pots and pans is not cooked. In the air pressure is greater than 1 atmospheric pressure, the water has to be higher than 100 ℃ will boil. People commonly used pressure cooker is designed to use this principle.

Pressure cooker to the water is quite tightly closed up, water evaporation produced by the heat of water vapor can not diffuse into the air, can only be retained in the pressure cooker, so that the pressure cooker inside the air pressure is higher than 1 atmospheric pressure, but also so that the water to be higher than 100 ℃ before boiling, so that the pressure cooker inside the formation of high-temperature and high-pressure environment, the rice is easy to do very quickly cooked, and quite crispy.
