What is the pressure in the pressure cooker?

The pressure of pressure cooker is determined according to the weight of pressure cap and the strength of spring. When the manufacturer designs, the wall thickness of the pressure cooker can bear the pressure of 2kg, while the weight of the gland and the strength of the spring are mostly designed between 0.5 and 0.8, so the pressure of the pressure cooker is generally 0.5-0.8kg..

The standard air pressure can also be measured by the temperature of the outer wall of the pressure cooker.

100 pressure difference between internal and external walls (MPa)

1 10 0.042 MPa

120 0.097 MPa

130 0. 169 MPa

140 0.260 MPa

150 0.375 MPa

The internal pressure can be known by temperature measurement.

Pressure cooker, also called pressure cooker, pressure cooker, is a kind of kitchen cooker. The pressure cooker exerts pressure on water through the physical phenomenon that the boiling point of liquid will rise under higher air pressure, so that the water can reach a higher temperature without boiling, thus accelerating the efficiency of stewing food. It can be used to heat cooked food to above 100℃. At high altitude, the pressure cooker can avoid the problem that the boiling point of water decreases and it is difficult to cook food. Its advantages are time-saving and energy-saving, but its disadvantages are that improper operation or defective operation may lead to explosion and personal injury.
