1. Please read the instructions before using the gland pressure cooker. According to the instructions, general food and water should not exceed 3/4 of the height of the pot; Boiled beans, dried corn, kelp and other easily expandable foods shall not exceed the height of the pot 1/2. And check whether the vent hole of the upper limit pressure valve on the cover is unobstructed, and clean the anti-blocking cover and safety valve (or explosion-proof fusible piece hole).

2. When cooking porridge and bone soup with a pressure cooker, the heat should be strictly controlled. Don't use too much firepower. When the pressure limiting valve on the top of the pot is steaming, the heat should be reduced to a suitable time. Don't leave the kitchen too far to do other things, so as not to let the temperature of the pressure cooker get out of control and cause accidents.

From the safety point of view, it is best to use the new pressure cooker with three risks. When cooking bone soup and porridge, turn off the fire properly before boiling to avoid overpressure when the pot boils.

3. Before opening the lid of the gland pressure cooker, after natural cooling or forced cooling with cold water, slowly lift the pressure limiting valve cover and hear the "hissing" exhaust sound, and then slowly open the lid after all the pressure in the cooker is discharged.

Some people cook porridge, but quickly open the lid before cooling and decompression. The hot porridge flew out with a bang, and it blistered one hand and one face. Although some people use cold water to cool down forcibly, it is also very dangerous to lift the cover without hearing the "hissing" exhaust sound after removing the pressure limiting valve cover. Sometimes, because the vent is blocked and the pressure is not released, blindly opening the lid is easy to cause burns.

4. Pay attention to the safe service life of pressure cooker. According to the manufacturer's regulations, the safe service life of pressure cooker is 8 years, beyond which it can only be used as an ordinary cooker.

5. After the pressure cooker is deformed, it should not be used as a pressure cooker, but only as an ordinary cooker.

Some people take the deformed pressure cooker back to its original state in order to save money, which is very dangerous. After the pressure cooker is deformed, it has destroyed the strength of the pot body and can no longer bear the pressure. Just like a middle-aged and elderly person, his lumbar spine was unfortunately broken. Although it is connected, he can no longer carry 100 kg as he used to.

For your happiness and safety, please use the pressure cooker safely.
