Electric pressure cooker (also known as pressure cooker, pressure cooker, etc. ) is a 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. At high altitude, using pressure cooker can avoid the problem that the boiling point of water decreases and it is difficult to cook food. Electric pressure cooker is an upgraded product of traditional pressure cooker and rice cooker. It combines the advantages of pressure cooker and rice cooker, and adopts new technologies and structures such as elastic pressure control, dynamic sealing, external rotating cover, electric switch with adjustable displacement, fully sealed cooking, continuous pressure adjustment, etc., which completely solves the safety problem of pressure cooker and relieves the potential safety hazard that ordinary pressure cookers have plagued consumers for many years. Electric pressure cooker has incomparable advantages over other cookers, which can meet all kinds of cooking needs and realize all kinds of cooking methods quickly, safely and automatically. Its characteristics of energy saving and nutrition are the direction pursued by modern people.
