The pressure cooker mainly relies on the pressure generated by the liquid to make the water temperature reach a high temperature without boiling, thus making the food cook faster. It should be noted that according to the different quality of rice and different tastes of everyone, it may be necessary to adjust the cooking time with low fire, but it must not exceed 10 minute, otherwise burnt rice will appear at the bottom of the pot, or you can choose to stew for a while after the valve falls.

Under normal atmospheric pressure, ordinary pot can only boil water to the boiling point of 100 degree, and then even if it is heated again, the temperature of water will not be higher than the boiling point, while the pressure cooker applies the principle that the air pressure is proportional to the boiling point of water.

Matters needing attention in using pressure cooker

1. Before use, check whether the air hole of the pressure limiting valve of the lower pressure cooker is blocked. If it is blocked, you can unclog the pressure limiting valve with a toothpick to keep it clean.

2. When cooking or cooking soup in a pressure cooker, the food in the pot should not be too full, usually 8 minutes is enough, because some foods will swell, especially things like beans, and it is best not to exceed half.

3. When closing the lid, pay attention to the marking line, and use it only after it is completely buckled. Just pay attention to the position, and don't push too hard to avoid damaging the card position.
