Electric pressure cooker is an upgraded product of traditional pressure cooker and rice cooker, which combines the advantages of pressure cooker and rice cooker, completely solves the safety problem of pressure cooker, and relieves the safety hidden trouble that ordinary pressure cookers have plagued consumers for many years. Its thermal efficiency is over 80%, saving time and electricity.
The working principle of electric pressure cooker is that the boiling point of water rises with the increase of pressure, that is to say, the temperature when water boils under normal pressure is higher than 100℃, so the cooking time will be shortened when the temperature when water boils in the cooker is higher than 100℃.

The first thing is to buy pressure cookers selectively. We must choose pressure cookers with brands, manufacturers, instructions and qualified quality. Don't buy fakes. Pressure cookers are divided into four types: 20.22.24.26 CM.
Generally divided into aluminum, aluminum alloy, stainless steel. They have their own characteristics: light aluminum, fast heat transfer, low price and service life of more than 20 years. But using it will undoubtedly increase the absorption of aluminum, and long-term use is not good for the body.
Aluminum alloy products are better, more durable and stronger than pure aluminum products. Although the stainless steel pressure cooker is expensive, it is heat-resistant, beautiful, difficult to react with acids, alkalis and salts in food, and has the longest service life, which can reach more than 30 years. Therefore, even if you spend more money at a time, you'd better buy stainless steel.
