In modern life, pressure cookers basically exist in the kitchen of every family. So what are the advantages of pressure cookers that make it so popular?
Nowadays, many people choose pressure cookers because they can save time. All you have to do is put the food into the pressure cooker and wait for it to eat. For example, it takes only 5 minutes to stew beef in a pressure cooker, while an enamel pot takes at least 40 minutes.
2. Cost saving
Less time means less consumption of gas and electricity. Although the price of gas is not expensive at present, cooking is a long-term matter. The effect of saving money will be obvious after a long time.
Safety is the most important thing for many people to consider when purchasing pressure cookers. The pressure cooker is in a high-pressure state during use. If used improperly, it will cause explosion accidents that we often see in the news. Before talking about safety, we should first understand the structure of a pressure cooker.
Generally speaking, the basic pressure cooker consists of a cooker body, a cooker cover, a pressure relief valve, a safety vent, a pressure indicator, a sealing rubber ring, and other exhaust channels.
Nowadays, there is no longer only a single vent hole on the pressure cooker, which is very dangerous once it is blocked. Instead, multiple safety measures are added. For example, the side safety hole can reduce the pressure in the cooker when there is a problem with the pressure relief valve, greatly reducing the probability of an explosion.
In addition, the material of the pot body is also an important embodiment of safety. At present, the pressure cookers on the market are mainly made of aluminum alloy and stainless steel.
The aluminum alloy pressure cooker price is relatively low, but these pressure cookers have low quality and low safety. Even if they are marked with multiple safety measures, it is not recommended to buy them.
Stainless steel is widely used at present. The stainless steel pressure cooker has high chemical stability, heat resistance, and corrosion resistance. It will not react with acid and alkaline food. Generally speaking, the pressure cooker made of stainless steel is more environmentally friendly and practical.
