Pressure cooker, also called pressure cooker, pressure cooker, is a kind of kitchen cooker. The pressure cooker exerts pressure on water through the physical phenomenon that the boiling point of liquid will rise under higher air pressure, so that the water can reach a higher temperature without boiling, thus accelerating the efficiency of stewing food. It can be used to heat cooked food to above 100℃. At high altitude, the pressure cooker can avoid the problem that the boiling point of water decreases and it is difficult to cook food.
