There must be countless kitchen items in every family, such as microwave oven, induction cooker and other electrical appliances. However, there is still a popular electric pressure cooker, which is a good helper for boiling soup. I believe every family has used it. But for the safety of electric pressure cooker, have you considered it? Do you know how to choose the electric pressure cooker? Do you know how to use it?
There used to be a very common pressure cooker, but now it has been upgraded to an electric pressure cooker. Naturally, the safety problem is not so serious. Ordinary pressure cooker is easy to explode, but the improved electric pressure cooker not only saves material, but also has high efficiency, and can save a lot of time.
First of all, we must choose the pressure cooker with brand, manufacturer, instruction manual and qualified quality. Don't buy fakes. Pressure cooker from the specification, generally 20, 22, 24, 26 cm four models. If you have a small population, you can buy a small size; if you have a large population, you should buy a large one. But in terms of thermal efficiency, you'd rather choose a larger one. Pressure cooker from the raw materials, generally divided into aluminum, aluminum alloy and stainless steel three kinds.
Each of the three has its own characteristics: aluminum is light in weight, fast in heat transfer, cheap in price, and has a service life of more than 20 years. But the use of it will undoubtedly increase the absorption of aluminum, long-term use of it is not good for health. Aluminum alloy is better than pure aluminum products, durable and strong. Although the stainless steel pressure cooker is more expensive, it is heat-resistant, beautiful, not easy to react with acid, alkali and salt in food, and its service life is the longest, up to more than 30 years. So, even if you spend more money at a time, you'd better buy a stainless steel one.
When using, first of all, carefully check whether the exhaust hole is unblocked and whether the hole under the safety valve seat is blocked by residual rice particles or other food residues. If it is blocked by food during use, the pan should be removed from the fire source and forced to cool down before the air hole can be cleaned. Otherwise, food will spray out and burn people. Also check whether the rubber sealing gasket is aged. The rubber seal ring will be aged after using for a period of time. The aged rubber ring is easy to make the pressure cooker leak, so it needs to be updated in time.
After reading the above content, I believe that you will have more experience in choosing and using pressure cooker than before. It is worth noting that TV is a very dangerous thing. The wiring at home must be checked regularly, otherwise it is very dangerous when using electrical appliances. In addition, we must follow the correct instructions when using electrical appliances.
