1. Avoid improper selection when buying a pressure cooker
The first is to purchase pressure cookers selectively, and be sure to buy them from a qualified pressure cooker manufacturer. Do not purchase counterfeit goods.
If considering the thermal efficiency, it is appropriate to choose a larger one. Pressure cookers are divided into raw materials, generally divided into aluminum and stainless steel. Aluminum is light and heat dissipation is fast. However, using it will undoubtedly increase the absorption of aluminum, and long-term use is harmful to health. The stainless steel pressure cooker is superior to the aluminum pressure cooker, and it is strong and durable.
Although stainless steel pressure cookers are slightly more expensive, they are heat-resistant, beautiful, hard to react with food acids, alkalis, and salt, and have the longest lifespan. Therefore, even if you spend more money, it is better to buy stainless steel pressure cooker.
2. Remember to read the instructions after buying a pressure cooker
Some people buy a pressure cooker without asking or learning, this is the most dangerous! Be sure to read the instruction manual when using the pressure cooker for the first time. Do as required, and you must learn how to use it.
3. Check after buying the pressure cooker
When using it, first carefully check whether the exhaust port is unobstructed and whether the hole under the safety seat is blocked by rice or other food residues. If it is blocked by food during use, it should be taken out of the pressure cooker, forced to cool, and can be used after cleaning the air vents, otherwise scalds may occur during cooking.
Also check whether the rubber gasket in the stainless steel pressure cooker is aging. Rubber seals will inevitably age after a period of use. The aging gasket is easy to make the pressure cooker leak, so it needs to be updated in time.
