2. Look at the inner container of the electric pressure cooker. The material of electric pressure cooker liner is also an important reference standard, mainly depending on the quantity and material of liner. Stainless steel liner is generally made of food-grade stainless steel, which is wear-resistant and safe. It should be the highest end of these materials, but it is not the best choice because of the heating blind area and easy to paste the bottom. The black crystal liner is made of high-strength alloy material, which is bright in color, high in strength, easy to clean and not easy to stick to the pot. Tao Jing liner is a layer of ceramic material attached to the surface of the liner. At the same time, the natural non-stick property, scratch resistance and far-infrared heating property of ceramic materials are used to improve the performance of the traditional liner, and the cooking thermal efficiency is 3-4 times higher than that of the traditional common hard liner. So I generally recommend the combination of stainless steel and Tao Jing.
3. Look at the control mode of the electric pressure cooker. Nowadays, electric pressure cookers are generally very intelligent. From heating to cooking, they are all done with one button, and no one needs to be present. However, considering that there are many elders who use pressure cookers, the choice of control mode is very important. Because of the particularity of the electric pressure cooker, touching the buttons will not have a mechanical feeling, so some people may be more complicated to use. There are two kinds of programs, one is to select all programs with one key, and the other is to directly press the relevant button to start the program.
4. Look at the safety of the electric pressure cooker. As I said at the beginning, the pressure cooker is still a little dangerous from beginning to end, so we should also see what additional functions can ensure our own safety and make ourselves feel more at ease when buying. At present, most of the electric pressure cookers on the market adopt floating sealing structure with the inner pot and the pot cover separated, which can automatically release the pressure when the pressure is too high, such as overpressure, which is quite reliable. Moreover, many control technologies such as pressure control and temperature control are adopted in the control, which can automatically realize the control range and is also very good.
For electric pressure cookers, in addition to understanding the above precautions when purchasing, you should also remember to do more inspections after purchasing. After a period of time, we should pay attention to the wear and tear of various parts, such as whether the apron is aging or not, which will cause trouble when using it. So try to be careful.
