Pressure cooker, also called pressure cooker, is a kind of kitchen utensil. The boiling point of the liquid in the pressure cooker at a higher pressure will enhance this physical phenomenon, so that the water can reach a higher temperature without boiling, so as to speed up the efficiency of stewing food. It can be used to heat the cooked food to more than 100 ℃. In high altitude areas, the use of pressure cooker can avoid the problem of reducing the boiling point of water and making it difficult to cook food.

Pressure cooker, also known as pressure cooker, pressure cooker. The advantage of using pressure cooker is that the cooking time is short, and the cooked food tastes good, especially the meat that is not easy to cook becomes easy to cook and tastes good. However, in the earliest days, the name of the pressure cooker was "Paping Pan", which was invented by a French doctor named Dennis Paping. Paping is not only a doctor, but also a physicist and mechanical engineer. Solid physical and mechanical theoretical knowledge is the reliable basis for his invention of pressure cooker.
