There is still residual gas in the pressure cooker after cooking, so it can't be vented immediately. It should cool naturally at room temperature. If you want to eat it right away, you can use the forced cooling method, that is, soak the pressure cooker in water to reduce the pressure, then stir the air outlet of the pressure cooker with chopsticks after cooling, and then slowly discharge the gas inside.

If it is a pressure cooker with pressure limiting valve style, you can gently lift the pressure limiting valve to let off the residual gas. When the float falls, the cover can be opened counterclockwise; If the float does not fall, it proves that there is still pressure in the pot. At this time, continue to press the indicator valve downward with chopsticks to exhaust the residual gas in the pot.

Matters needing attention in using pressure cooker

1, check regularly. Check whether the gasket on the pressure cooker cover is yellow, whether the pressure cooker cover is buckled in place, and whether the pressure limiting valve and float valve are blocked.

2. The weight of food. When cooking food in a pressure cooker, you need to pay attention to the amount of food to prevent too much food from blocking the air valve during cooking.

Don't open the lid immediately after the food is cooked. After the food is cooked, wait until the gas in the pressure cooker is completely released, then take down the pressure valve and open the lid.
