Haven’t used it; there are fears involved, so I don’t know
170,000 Pa, around 115°C.
Generally, the weight in a pressure cooker is adjusted to achieve a pressure balance of 20 kPa; therefore, the operating pressure of such a cooker is 20 kPa at 105°C.
Is it accurate? Everyone has different opinions
Working pressure levels: 70KPa (170KPa), 80KPa (180KPa), 90KPa (190KPa); higher working pressures cause greater damage to nutrients.
The nominal operating pressure of most pressure cookers is 80 kPa, which corresponds to an operating temperature of 117–118°C.
As far as I know, the nominal operating pressure of most pressure cookers is 80 kPa, which corresponds to an operating temperature of 117–118°C.
Standard answer: I’ve managed to measure it, and it’s generally around 110-115 degrees. As long as what is being cooked inside is not a saturated aqueous solution of sodium chloride or calcium chloride, nor liquor, but rather food, it’s more or less like this.
It’s best for families not to use pressure cookers! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
