Pressure cooker, also known as pressure cooker, the original name is called "Papein pot", is a French doctor Denis Papein invented, not initially used to cook food, but a disinfection apparatus. Modern improvement into a kitchen cooking food a pot, we basically know that the plateau region of low air pressure, such as Tibet, the temperature of boiling water for 75-82 ° or so, with the ordinary pot to cook rice out of the rice, so you must use the pressure cooker, and ordinary pressure cooker, such as unfamiliar with the operation, it is easy to cause an explosion or an accidental danger.
Traditional pressure cooker material is better, the product can withstand greater pressure, traditional pressure cooker pressure 100kpa is the basic indicators, and electric pressure cooker to reach 90 are rare. Use characteristics. Because the electric pressure cooker can adjust the cooking time, in what food needs how much time to make a setting on the OK. and its work is completely in a sealed state, electric pressure cooker heat source is electricity, electric pressure cooker insulation is good, and there is no hot water gas overflow, I think it is more energy-saving a cooking method.
When the temperature and pressure inside the electric pressure cooker reaches a certain value, the exhaust valve will automatically close and the flavor will not be lost. The food inside the pot is kept in a safe state of high temperature and pressure, and the various foods boiled are more delicious and can be said to be original. Later, I don't know when, electric pressure cooker appeared in people's lives, and by the public unanimous favorite. The principle of electric pressure cooker and pressure cooker is actually the same, except that one is heated by electricity and the other by open fire.
Chinese people love to cook, like in the pots and pans in the bump in the life, and in the many pots and pans, the pressure cooker is more practical one. As far as we can remember, when people used to stew some kind of food, they had to simmer for a long time before the food would be stewed. If the automatic power failure, the pressure reducing valve failure, the pressure inside the pot increases will be the pot in the body of the gallbladder downward displacement, displacement so that the bottom of the pot the second disconnecting master switch separation cut off the power supply no longer heated to ensure that the pressure is safe.
