Background

The micro-pressure cooker is a cooking utensil for heating food at a speed between that of a pressure cooker and that of a common cooker. The pressure cooker can heat food quickly by increasing the pressure in the cooker, but the liquid temperature in the cooker is higher in the process of heating food, which easily causes damage to the nutrient content of some food, so the pressure cooker is not suitable for heating food which is easy to lose its nutrient content under high temperature condition, and if the pressure cooker is not operated properly, the pressure in the cooker is higher, which may have a certain safety hidden trouble. However, if a common pot is used for heating food, the defect of too low heating speed generally exists. Therefore, in order to not damage the nutrient components of the food in the pan, not influence the heating speed of the food and eliminate the potential safety hazard, the micro-pressure pan can be used for heating the food. The atmospheric pressure in the pressure cooker is generally lower than 1.2 atmospheric pressure when the pressure cooker works, namely lower than the atmospheric pressure in the pressure cooker when the pressure cooker works, under the atmospheric pressure, the pressure cooker can heat food more quickly than a common cooker, and the liquid temperature in the pressure cooker is not too high to cause the loss of food nutrient contents.
