Pressure cooker working principle is the use of no-boil cooking food, the use of the boiling point of water by the air pressure of this physical characteristic.

Often boiling water at 1 atmospheric pressure, the water will boil at about 90-105 ℃, while the pressure cooker inside the air pressure is generally 1.5 atmospheric pressure, the boiling point of water is generally about 110-130 ℃. This will create a high-temperature, high-pressure environment inside the pressure cooker, and the rice is cooked quickly.

A pressure cooker, also known as a pressure cooker, pressure cooker, is a kitchen cookware. Pressure cookers apply pressure to water through the physical phenomenon that the boiling point of liquids rises at higher air pressure, so that the water can reach a higher temperature without boiling, in order to speed up the efficiency of stewing food.

It can be used to heat the food being cooked to over 100 degrees Celsius, and at high altitudes, the use of a pressure cooker avoids the problem of water having a lowered boiling point that makes it difficult to cook food.

Functions of pressure cooker:

Pressure cooker is divided into ordinary and now popular electric pressure cooker. If it is an ordinary pressure cooker, the function is less, the main function is to stew things. If the electric pressure cooker, the function is more, not only can stew things, but also can cook rice, make steamed meat, braised vegetables, but also can make cake.

Precautions for pressure cooker:

The amount of water filling and sealing. When using the pressure cooker to cook food, the amount of water filling should not exceed the water filling line of the pressure cooker or two thirds of the pressure cooker, otherwise it will easily cause dangerous phenomena such as frying or spraying soup. At the same time, be sure to pay attention to the pressure cooker closed, pot and lid alignment to ensure sealing.
