1. Pressure cooker, also known as pressure cooker, is a kind of kitchen cooker.
2. The pressure cooker increases the boiling point of the liquid at a higher pressure and exerts pressure on the water to make the water reach a higher temperature without boiling, thus speeding up the efficiency of stewing food.
3. It can be used to heat cooked food to more than 100 degree . In high altitude areas, pressure cookers can avoid the problem of lowering the boiling point of water and making it difficult to cook food.
4. Its advantages lie in saving time and labor, while its disadvantages lie in the possibility of explosion and injury in case of improper operation or defects.
