The time for cooking porridge in pressure cooker is generally 20 minutes.

The amount and consistency of porridge are different, and there is still a difference in time. As for how much water to put, the ratio of rice to water is generally 1:3. Of course, some people like to drink thin porridge, and some people like to drink thick porridge, so the amount of water can be increased or decreased appropriately.

Matters needing attention in the use of pressure cooker:

First, pay attention to the food storage capacity of the pressure cooker. When cooking, the food put into the pressure cooker should not exceed four-fifths of the pressure cooker body. Too much food is not conducive to pressure cooker cooking, but may block the pressure cooker exhaust hole.

Second, the closure should be strict. After covering the pot cover, the two handles of the pot cover and the pot body should overlap together, and at the same time, check whether the exhaust hole is unobstructed.

Third, buckle the upper limit pressure valve in time. After the pressure cooker catches fire, when the steam emerges from the exhaust pipe stably, the pressure limiting valve should be locked in time. There can be nothing else to pressurize the pressure limiting valve, and there can be nothing else to replace the pressure limiting valve.

Fourth, pay attention to reducing firepower. When the pressure limiting valve is lifted by the steam impulse, the firepower should be reduced and the fire should be slow until the food is cooked.

Fifth, open the lid after cooling. When the food is cooked and out of the fire, take the valve and open it when the pot is cold. If it's not cold, open the lid and eat it in a hurry. You can use cold water to force the temperature to drop.

Sixth, always check the apron of the pressure cooker. It is very important to protect the apron of the pressure cooker. If it is used for a long time and the apron is crushed, it needs to be repositioned. If the rubber ring is aging, it should be replaced in time.

In addition, the service life of the pressure cooker should not be too long. Generally 8 to 10 years. Pressure cookers should not be "out of service" and should be replaced in time after their service life is exceeded.
