How to Prevent a Pressure Cooker from Exploding

A pressure cooker is a must-have in the kitchen. It cooks food quickly, saves time, saves fuel, and cooks more delicious food, but if used incorrectly, it can be dangerous and potentially explode! Generally speaking, blockage of the pressure cooker vent valve, too much food, and prolonged use may cause the pressure cooker to become a time bomb! Therefore, we must be very careful when using the pressure cooker.

What caused the pressure cooker to explode?

• The pressure cooker vent valve is blocked, resulting in excessive pressure.

• There is too much food in the pot; when cooking porridge, beans and other granular or easily foaming food, the food particles will block the air passage of the pressure limiting valve, so that the high-pressure steam inside cannot be discharged from the pot, resulting in strong pressure in the pot. constant increase. When it exceeds the damage pressure that the pot body can withstand, the pot body will be deformed, resulting in that the pot cover cannot be fixed along the edge of the pot, and the pot cover will fly out under the strong pressure in the pot, resulting in casualties and property losses.

• If the service life is too long, the pot body will age and deteriorate. The aging of the pot body also reduces the pressure that the pot body can withstand, increasing the hidden danger of explosion. During the long-term use of the pressure cooker, due to repeated heating, scratches during cleaning, acid-base corrosion, mechanism wear, etc., the pot body will be scratched and the pressure resistance performance of the pot body will be reduced.

How to prevent a pressure cooker from exploding?

• Before use, carefully check whether the air hole of the valve seat of the pot cover is unblocked and whether the safety plug is in good condition.

• The food in the pot cannot 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, when the steam starts to be discharged from the air hole, the upper pressure valve is closed.

• When heated to the point where the pressure limiting valve makes a loud hissing sound, it should be cooled down immediately.

• If the safety plug is found to be exhausted during cooking, it is necessary to replace the new fusible sheet in time, and do not block it with iron wires, cloth strips, etc.

Precautions for using pressure cooker

• Before use, first check whether the exhaust pipe hole is unblocked, and then put the food into the pot, but the food should not exceed 4/5 of the pot capacity. Then put the lid on, turn the lid in the direction of "close" indicated by the arrow on the lid, until the two handles are completely overlapped.

• After closing the cover, when the steam is stably discharged from the exhaust pipe, fasten the pressure limiting valve on the exhaust pipe. No other weights shall be added to the pressure limiting valve, let alone replaced by other things. cooking time for various types of food,

• Before opening the lid, if there is air pressure in the pot, it should be cooled and depressurized. It can be cooled naturally, or you can pour cold water on the pot to cool it forcibly. Then, remove the pressure limiting valve, and when the exhaust pipe is no longer deflated, turn it in the "open" direction (that is, counterclockwise) as indicated by the arrow on the pot, and open the pot lid.

• When making porridge, when the pressure limiting valve is deflated and lifted, the pot should be removed from the fire immediately to prevent the rice soup from being sprayed.

• 5, easy to dissolve plug holes, to keep clean. When the soluble metal in the hole is taken off, it should be replaced separately and must not be replaced with other things.

• Wash and dry at any time after use. The lid of the pot should be placed on the pot body instead of being combined with the pot body to prevent the sealing rubber ring from being deformed and leaking during use.

• It is not advisable to store alkali salt soy sauce for a long time in the pot to prevent corrosion. The residual food sticks to the pot body, it can be soaked in warm water for brushing. Do not scrub with limestone, etc.

• The pot cover, pot body and pressure limiting valve should be properly kept to prevent bumping so as not to damage the seal of the pot and lose the function of the pressure cooker. When holding the pot, the main and auxiliary handles should be lifted at the same time to reduce the force on one end of the pot handle and prevent the pot handle from being damaged.
