【Concept】
Also known as a pressure cooker , it can be heated to cooking food above 100 ℃ .
It features a unique high temperature and pressure , greatly reducing the cooking time , saving energy ;
But the working pressure of the pressure cooker on the nutritional damage is relatively large.
=============================
【Principle term】
The principle of a pressure cooker is very simple, because the boiling point of water affected by the pressure , the higher the pressure , the higher the boiling point .
In the mountains, plateau, less than 1 atm pressure , less than 100 ℃ water can boil eggs cooked with ordinary cookware is unfamiliar .
At a pressure greater than atmospheric pressure , the water is necessary only when at higher than 100 ℃ boiling.
It is now commonly used in the pressure cooker is designed using this principle .
Pressure cooker fairly closely the water closed, the water vapor produced by evaporation heat can not diffuse into the air, can remain in the autoclave , the pressure is higher inside the pressure cooker
1 atm , but also the water to boil at higher than 100 ℃ only , so that the formation of high temperature and pressure inside the pressure cooker environment easily and quickly cooked rice on a .
Of course, the pressure inside the pressure cooker would not be without limits , or to become a bomb.

【Features Terminology】
--------------------
1 [ ordinary aluminum pressure cooker ]
Light weight, heat and fast , cheap, anti-corrosion surface alumina layer ( avoid damage ) , you can quickly cooled with cold water , useful lives used one hour per day basis, the service life of 8 years , not suitable for induction .
--------------------
2 [ stainless steel clad bottom aluminum pressure cooker ]
Like fit cooker with stainless steel pressure cooker , aluminum pressure cooker along with the advantages of common , open flame fires when used bogey , at the bottom to prevent rapid cooling to prevent deformation of stainless steel clad bottom off .
--------------------
3 [ stainless steel pressure cooker ]
Expensive : Heat , beautiful , easy , and food acids, bases, salts react , one day one hour useful life is 10 years or so, suitable for induction cooker, a gas stove, electric stove easy to change color , can not be rapidly cooled with cold water , inappropriate torment medicine.
--------------------
4 [ electric pressure cooker ]
Easy to use expensive , work pressure 50KPa (150KPa) low , with insulation function, you can remove the inner pot replacement . Intelligently anhydrous Dunyu stew, not automatic power-off would have been spaced heat insulation . Related to the aging problem unlike a pressure cooker and long working life . However, electric pressure cooker casing can insulation, energy-efficient than traditional pressure cooker naturally high . Although gas prices are not expensive, but usually more than 1 hour cooking time was not enough carbon .
=============================
【Structure Terminology】
By a steel body and cover , fusible film , bleed hole , safety valve and sealing ring, and other new forms of bleed channels.
Soluble tablets ---
The safety valve fails to prevent the role sky spare fuse , a low melting point which is made ??of aluminum alloy material .
Once the valve fails, the pressure pot is too large , the temperature will be increased when the temperature reaches the melting point of soluble tablets , and then continue heating soluble film begins to melt , the pot begins soluble tablets ejected gas , so that the pot pressure decreases , thereby preventing an explosion accidents.
=============================
【Terminology security risks】
--------------------
1 [ pressure control safety devices ]
During use , such as when the pressure exceeds the set off automatically .
--------------------
2 [ venting safety device ]
When the pressure limiting safety device failure pot pressure exceeds the safety value, the relief agency work, so that the pot around the automatic wastegate to ensure that no accidental blasting pot .
--------------------
3 [ pressure limiting safety device ]
When the pressure was increased in pot limit, limit pressure release valve auto exhaust pressure limiting .
--------------------
4 [ power and memory protection device ]
Unplug the power cord during a power outage or another new call, or connect the power , it can automatically set before the power failure continue to function .
--------------------
5 [ limit temperature safety device ]
When the pot temperature rose to the limit, automatically cut off the power.
--------------------
6 [ attempts to prevent the safety device ]
Exhaust valve to prevent clogging of food to ensure that the exhaust valve open.
--------------------
7 [ opening and closing lid safety device ]
When fastening the lid and the pot is not in place , the pot pressure can not rise . When the pot pressure higher than the safety value, not opening the lid.
--------------------
8 [ over-temperature safety device ]
When the pot or pan air burning temperature exceeds the set safety value , automatically cut off the power.
