Pressure cooker, also known as pressure cooker and pressure cooker, is a kind of kitchen cooker. Through the physical phenomenon that the boiling point of liquid will rise under higher air pressure, pressure is exerted on water to make it reach a higher temperature without boiling, thus accelerating the efficiency of stewing food.
The advantage of pressure cooker is time-saving and labor-saving, but the disadvantage is that improper operation or defects may lead to explosion and personal injury.
Mung bean soup is cooked in a pressure cooker. When mung beans are cooked, it is easy to block the air outlet valve. After the outlet valve of the pressure cooker is blocked, the pressure in the cooker will continue to rise. If the pressure in the pot is too high, there is a danger of explosion. Therefore, it is recommended not to cook mung bean soup in a pressure cooker.
In fact, as long as the operation is proper, the probability of the above explosion is extremely low.
Operation essentials of cooking mung bean soup in pressure cooker;
When cooking mung bean soup in a pressure cooker, be careful that the amount of soup should not exceed half of the capacity. After boiling, simmer 10 minutes and turn off the heat. And when opening the pressure cooker, wait until the pot body is completely cooled and there is no pressure before opening the lid.
At present, there are two kinds of pressure cookers on the market: ordinary energy pressure cookers and electric pressure cookers.
Ordinary energy pressure cookers are not as safe and environmentally friendly as electric pressure cookers, but they have long service life and low price.
The electric pressure cooker is easy to use, slightly expensive, with low working pressure of 50KPa( 150KPa), heat preservation function, and the inner cooker can be disassembled and replaced. Fish can be stewed intelligently, without water, without automatic power failure, and can be heated and kept warm at intervals. The problem of line aging is not as long as the service life of pressure cooker. The shell of the electric pressure cooker can keep warm, and the energy efficiency is naturally higher than that of the traditional pressure cooker. Although gas is not expensive, cooking time above 1 hour is obviously not low-carbon.
Instructions for use of pressure cooker
(1) Before each use, carefully check whether the exhaust hole of the pressure-limiting valve is unobstructed (it can be cleaned with a toothpick) and keep the anti-blocking cover clean;
(2) The food in the pot should not be too full, generally not exceeding four fifths of the pot height. For foods that are prone to flatulence (such as kelp, mung beans, corn, etc. ), do not exceed half of the pot body;
(3) When closing the lid, mark the lid and the pot body and fasten them completely. Stop where you are, don't overdo it;
(4) After the sealing cover is heated, when more steam is discharged from the pressure limiting vent, the pressure valve cover is buckled;
(5) When the pressure limiting valve is working, turn down the firepower and keep the pressure limiting valve inching;
(6) Before opening the cover, the cover can only be opened after the pressure is completely reduced, that is, the valve core of the protection device is lowered and reset. Do not pull the handle hard;
(7) General pressure cookers stipulate that the safe service life shall not exceed eight years.
