Pressure cooker 10 minute is about equivalent to ordinary pot stewing for about 40 minutes. If the ordinary pot used for soup needs to be stewed for two hours, then the pressure cooker usually needs to be stewed for about 30 minutes, and the specific time needs to be determined according to the type and quantity of food.

Pressure cookers exert pressure on water through the physical principle that the boiling point of liquid will increase at higher air pressure, so that the water can reach a higher temperature and the efficiency of stewing food can be accelerated. In high altitude areas, food that is not easy to cook can be cooked by pressure cookers.

Matters needing attention in using pressure cooker

1 Check the pressure cooker before use. Check that there are no indentations and cracks on the pressure cooker, and also check whether the food in the pressure cooker has been cleaned. If there are cracks in the pressure cooker, it will be dangerous. We know that the steam in the pressure cooker can easily burn people.

2. The pressure cooker needs to be cooled and deflated, and the cover should be opened according to the requirements in the manual, because the use methods are different for different pressure cookers with different structures.

3, in the process of heating, never open the lid in the middle, lest the food burst into hot people. Do not remove the heavy hammer or pressure regulating device before the cooling is confirmed, so as not to spray food and hurt people. The cover can only be opened after natural cooling or forced cooling.
