So that the gasket and the bottom plate are fully contacted. Then cover the lid, hold the handle of the lid by hand, tighten the lid counterclockwise, and adjust the exhaust valve to a sealed state.
Finally, plug in the power supply, adjust the cooking mode on the control panel, press the start button after confirmation, and the electric pressure cooker will start running.
Improper choice:
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. You can buy a trumpet with a small population; With a large population, it is natural to buy a large size.
But considering the thermal efficiency, you'd rather choose a bigger one. Pressure cookers are divided into aluminum, aluminum alloy and 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.
