Pressure cooker after the use of exhaust methods: after cooking, can be at room temperature for natural cooling, such as to be consumed immediately, can be used to force the cooling method (i.e., water drench or immersed in water) to reduce the pressure, cooling is complete, you can gently put out the pressure valve, will be the remaining gas release.

Points for safe use of pressure cooker:

1, do not put rags or other things on the pressure-limiting valve, which may lead to blockage of the valve, thus failing and causing accidents.

2, before using the pressure cooker, check whether the lid is sealed, whether the exhaust system is smooth and whether the pressure limiting valve is in place.

3, the food in the pot should not exceed 4/5 of the capacity (including the height of the liquid level), and it is better not to cook bean food more than 2/3, so that the food will not be steam-cooked and produce gas that will lead to expansion, and block the vent holes, and the food in the pot should not be too little.

Expanded:

Electric pressure cooker should pay attention to:

1, the pressure control safety device: in the process of use such as exceeding the set pressure can be automatically cut off.

2, pressure relief safety device: when the pressure-limiting safety device fails to pot the air pressure exceeds the safety value, the pressure relief mechanism works, so that the pot around the automatic exhaust pressure relief, to ensure that there will be no accidental pot explosion.

3, pressure-limiting safety device: when the pot pressure increases to the upper limit, the pressure-limiting valve automatically exhaust pressure limit.

4, power failure memory protection device: in the power outage or unplug the power cord and then from the new call, or connect the power supply, can automatically continue to set the function before the power failure.

5. Temperature-limit safety device: when the temperature in the pot rises to the limit, it will automatically cut off the power supply.

6, anti-clogging safety device: to prevent food clogging the exhaust valve, to ensure that the exhaust valve is smooth.

7, open and close the lid safety device: when the lid and the body of the pot is not fastened in place, the air pressure inside the pot can not rise. When the air pressure in the pot is higher than the safety value, the lid cannot be opened.

8, over-temperature safety device: when the pot is empty or the temperature inside the pot exceeds the set safety value, the power supply will be cut off automatically.

Methods to prevent the explosion of the pressure cooker:

1, before use, we should carefully check whether the valve seat of the lid of the air hole is free, whether the safety plug is intact.

2, the food in the pot can not exceed 4/5 of the capacity. When the lid is closed, it must be screwed into the slot and the upper and lower handles are aligned. When cooking, snap on the pressure limiter when steam begins to escape from the air holes.

3. When the temperature is increased to the point where the pressure limiting valve makes a loud hissing sound, reduce the temperature immediately.

4, cooking, such as found in the safety plug exhaust, to replace the new fusible links, do not use wire, cloth and other things blocked.
