The principle of the pressure cooker is very simple, because the boiling point of water is affected by the air pressure, the higher the air pressure, the higher the boiling point. On high mountains and plateaus, the pressure is less than 1 atmosphere, and water can boil at less than 100°C. Eggs cannot be cooked in ordinary pots. When the air pressure is greater than 1 atmosphere, the water will not boil until it is higher than 100°C. The commonly used pressure cooker is designed using this principle.
2. The high-quality pressure cooker seals the water quite tightly. The water vapor produced by the evaporation of the water cannot diffuse into the air, and can only be kept in the pressure cooker, so that the pressure inside the pressure cooker is higher than 1 atmosphere, and the water must be higher than It only boils at 100°C, so that a high-temperature and high-pressure environment is formed inside the pressure cooker, and the rice is easily cooked quickly and is quite crisp.

Because of its airtight and high-pressure characteristics, it is easy to be cooked, perishable, time-saving, and the loss of nutrition and flavor is relatively small when processing food.
2. The high-quality pressure cooker is stamped from high-quality aluminum or stainless steel, and its working pressure is 80-100 kPa. When choosing a high-quality pressure cooker, in addition to looking at whether the surface is smooth, whether there are alkali stains, oil stains, and water stains inside and outside the pan, it is more important to check whether there are defects such as pits, collapses, scratches, burrs, and whether the bottom and sides of the pan Smooth, round and tidy, with or without pores and slag inclusions.
