How to exhaust the pressure cooker after use, and how to exhaust the pressure cooker when it is used

After the pressure cooker is removed from the stove (or turned off the heat), leave it alone, as the temperature drops, the pressure of the gas inside will gradually decrease. The sealing of the pressure cooker is not air-leaking, it just takes time, after the pressure cooker is removed from the stove, the residual heat will still work, turn off the heat in advance, and also save gas. If you are in a hurry, you can use a wet towel soaked in water and put it on the lid to force it to cool quickly, as the temperature drops, the steam pressure in the pot will shrink and decrease.

No venting required.

Exhaust method after the use of pressure cooker: after cooking, it can be naturally cooled at room temperature, if you want to eat immediately, you can use forced cooling method (that is, drenched with water or immersed in water) to reduce pressure, after cooling, you can gently lift the pressure limiting valve to release the remaining gas.

Key points for safe use of pressure cookers:

1. Do not put rags or other things on the pressure limiting valve, as this may cause the pressure limiting valve to be blocked, which will fail and lead to 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 best not to exceed 2 3 for boiled bean food, so as not to cause expansion due to gas production after cooking, block the exhaust hole, and the food in the pot should not be too little.

No, you don't.

A pressure cooker, also known as a pressure cooker, is a kind of kitchen cooker. The pressure cooker elevates this physical phenomenon by the boiling point of the liquid at higher air pressure, exerting pressure on the water so that the water can reach a higher temperature without boiling, thus speeding up the efficiency of cooking food.

It can be used to heat cooked food to more than 100 degrees, and at high altitudes, the pressure cooker can avoid the problem of low boiling point of water and difficult to cook food.

Features of the pressure cooker:

Ordinary aluminum alloy pressure cooker is light in weight, fast in heat transfer, cheap, has an alumina layer on the surface to prevent corrosion (avoid damage), can be quickly cooled with cold water, and the service life is calculated by 1 hour of use per day, and its service life is 8 years, which is not suitable for induction cooker.

The stainless steel composite bottom aluminum alloy pressure cooker is as suitable for induction cooker as the stainless steel pressure cooker, and at the same time has the advantages of ordinary aluminum alloy pressure cooker.

Stainless steel pressure cooker **expensive: heat-resistant, beautiful, not easy to react with acid, alkali and salt in food, and the service life of one hour a day is about 10 years. It is suitable for induction cooker, easy to change color on gas stove and electric stove, and cannot be quickly cooled with cold water, and is not suitable for torturing traditional Chinese medicine.

It will automatically exhaust when in use, and manual labor cannot actively exhaust it.

Here's how to use it:

First, check whether the exhaust pipe on the lid of the pot is unobstructed, and then cover the lid tightly.

Second, wait until a small amount of vapor is discharged from the exhaust pipe, and then buckle the pressure limiting valve to the exhaust pipe.

Third, do not put anything on the pressure limiting valve to prevent accidents due to the failure of the pressure limiting valve.

Fourth, before boiling, it is necessary to carry out natural or forced cooling. However, it is not possible to force exhaust.

Fifth, especially if you are cooking a thin thing, you can't use the method of removing the pressure limiting valve to deflate it, so as to prevent the thin thing from squirting out and hurting people.

Sixth, when the exhaust pipe is exhausted, the lid must not be opened to prevent food from squirting and hurting people.

Seventh, once the fusible plug is damaged, it should be replaced with a new one in time and cannot be replaced by other things.

After the rice is cooked, if it is a non-liquid food such as rice, you can manually exhaust it to speed up the opening of the lid. If the soup in the pot cooks porridge, do not exhaust, because the liquid food in it will be discharged with the gas, so that on the one hand it is unhygienic and on the other hand, it is easy to burn, at this time you can use a wet towel on the lid of the pot to speed up the cooling, generally more than a minute can open the lid.

It is automatically vented when it reaches a certain pressure.

After the food is cooked, wait for it to cool naturally, and then turn on the pot when the exhaust valve automatically drops.

Don't put it in cold water, pour it with cold water, cover it with a damp cloth or something, it's not safe

Generally, it is not discharged, and there is a little discharge when the pressure is super high.

No, there is a dedicated exhaust hammer.

Turn off the fire of the high-pressure boiler first, and wait for the internal pressure of the pressure cooker to naturally decrease to 0, generally speaking, you need to wait for about 10-15 minutes.

Gently turn the vent valve on the pressure cooker to slowly release the residual steam from the pan. When deflating, keep your hands at least 10 cm away from the vent valve to avoid being scalded by the high-temperature steam sprayed. Wait until there is no steam coming out of the pressure cooker stool, then gently open the lid of the pressure cooker with a spatula or other tool, and carefully pour out the food or water inside.

It should be noted that do not force open the lid of the pressure cooker or use sharp objects to deflate when there is still pressure inside the pressure cooker, as this will cause serious safety accidents. The correct deflation method can ensure that the pressure inside the pressure cooker is effectively released and ensure safe cooking.

Precautions for using a pressure cooker

1. Choose the right pressure cooker: Choose the right pressure cooker according to your own needs and frequency of use, generally speaking, a high-capacity pressure cooker is suitable for home use.

3. Do not add too much water: When using the jujube pure pressure cooker, the amount of water should not be too much, and the water level should not exceed the maximum marking line of the pressure cooker, otherwise accidents may occur.

4. The size of the ingredients should be uniform: When using a pressure cooker, the size of the ingredients should be uniform to ensure that the ingredients can be evenly heated and avoid uneven cooking or boiling of the ingredients.

5. Ingredients should be pre-treated: When using a pressure cooker, some ingredients need to be pre-treated, such as meat needs to be cut into small pieces, and beans need to be soaked in advance to ensure that the ingredients are easier to cook.

After the pressure cooker is ready, the first step is to immediately turn off the fire, and the second step is not to remove the pressure limiting valve immediately, be careful of burns! If you want to turn on the pressure cooker immediately, you can put the pressure cooker under the faucet, turn on the faucet to cool down, the faucet should not be too big, avoid splashing outside the pool, and just flush with water for a while. If you gently open the valve a little and still spray out, it means that the air pressure in the pressure cooker is too great to open it yet, and you have to continue to flush.

Wait until you don't spray to open it to avoid burns.

After the pressure cooker is cooked, it should not be exhausted immediately, and it can only be exhausted after a certain period of cooling down, otherwise, it will be easy to burn the heat immediately!

1. Choose a rag and cover it over the pressure cooker.

2. Rotate the pressure relief valve of the pressure cooker by hand to let the steam be discharged from the pressure relief valve. Covering with a rag will not only prevent burns caused by excessive steam, but also prevent water from spilling out of the pressure cooker.

3. It is expected that after putting it out, the rag can be removed.

5. After the pressure is released, you can rotate the lid of the pot, open the pressure cooker, and see the finished food in the pot, you can take it out and eat.

When operating a pressure cooker, the safety valve always vents automatically, which is normal:1. Cooking food in a pressure cooker, with special heat, will evaporate and expand the water in the pot when the temperature reaches 100.

If the steam cannot be discharged, the pressure in the pot will rise, exceeding the compressive strength of the pot, and ** will occur. To ensure safety, the pressure cooker is equipped with a variety of protection devices, of which the safety valve is the most important protective element. 2.

When the pressure reaches the design value, the gas will be automatically discharged from the safety valve to ensure that the pressure in the boiler is within a safe range. Therefore, when heating continues, the exhaust valve will continue to vent until the heating stops.

Manual venting of a pressure cooker is a very dangerous operation, and it is best to physically cool down to reduce the pressure. It is to cover the lid with a wet towel, or directly pour water on the lid of the pot, which is faster than manual exhaust and depressurization.

The steps to do it correctly are as follows:Ingredients: pressure cooker, wet hunger rag.

1. Unplug the power of the pressure cooker.

2. Put a rotten rock wet rag on the deflating valve.

3. Rotate the tail of the vent valve to deflate the pressure cooker.

4. Rotate the lid of the pressure cooker clockwise by hand to the opening and closing opening.

5. Lift the lid of the pressure cooker upwards.
