Use of pressure cooker

Kim, Secretary General of China Hardware Products Association: The main cause of the pressure cooker explosion is improper use.

Which of the following methods is incorrect?

Secretary-General Jin of China Hardware Products Association: Meat, rice, will block the air hole. Many explosions are due to this.

It seems that cooking in a pressure cooker is too greedy and dangerous. Secretary-General Jin also introduced that if one of the gas holes, pressure limiting valves and relief valves of the pressure cooker is blocked, it would also be dangerous. Because if their function is mainly to keep the pressure in the pot stable, if any of them is blocked, the pressure in the pressure cooker will not be able to relieve pressure, and the pressure in the pot will increase and eventually lead to an explosion. You also need to be reminded that the fire has been burning for a long time, and the pressure generated in the pot exceeds the discharge pressure, which will also lead to an explosion. Finally, we remind you that the use of inferior pressure cookers will also cause an explosion.

It seems that when we use a pressure cooker in the future, we can't be careless. So what is the correct way to use the pressure cooker?

Food and water cannot be too full, preferably less than 2/3; When stamped, the upper and lower three alignment, spin into the tank, until the upper and lower handles alignment, after the fire, when the steam steadily emerges from the exhaust pipe, the pressure limiting valve can be promptly deducted. The pressure limiting valve cannot be pressed against other items, and other items cannot be used to replace the pressure limiting valve. When the pressure limiting valve is lifted by Steam Force and hears the noise, it should immediately reduce the fire until the food is cooked. After the fire is turned off, you need to wait for the pot to cool down and then remove the limit valve, open the lid, otherwise it may be due to the pressure inside the pot is too large and the lid rushed up, there is a risk. If you are eager to eat, warm water or cold water can be slowly poured on the lid to force cooling, but natural cooling is the best.

How is it? Is this how you use a pressure cooker? If not, you must change it immediately.

We also want to remind you that you should not forget to carefully maintain your pressure cooker. We recommend that you carefully clean the air hole, pressure limiting valve, and relief valve after each use of the pressure cooker. So how do we know that the three parts are cleaned and not blocked?

Secretary-General Jin of China Hardware Products Association: This is to prevent congestion. Looking at the sun, the relief valve is pushed by hand. If it can be moved, it means it is not blocked.

The pressure limiting valve you may use a fine stick from these three holes in the past, you can see in the middle of the stick is smooth. There is also the glue ring in the pressure cooker. It is an important part to ensure the tightness of the pressure cooker is good. Don't forget to change it regularly.

When washing the rubber ring, it is best to rinse it with water together with the lid, to clean the residual residue attached to the rubber ring, do not take it down to wash it separately, avoid stretching the rubber ring, sealing is affected.

After talking about the usage and maintenance methods, we will finally tell you how to select a pressure cooker?

1. Check whether the factory name, trademark, model, and executed standard number are complete.

2. check whether there are scars and deformation on the pot body and lid.

3. the rubber sphere shall contain the manufacturer's trademark (or manufacturer's name) and specification.

4. check whether there is a pressure relief device. The qualified device can effectively prevent overpressure explosion of the pressure cooker.

Don't be scared by the explosion in the pressure cooker of Shi qiuju's family. In fact, the pressure cooker has been very secure after many technical updates in recent years. It will not change. As long as we purchase products from regular manufacturers and use them properly, it is a good helper in our kitchen. We hope our program will help you.
==========================================
The pressure cooker is also called a pressure cooker. It has been emerging for more than a decade. It has been popularized to thousands of households with unique functions, greatly shortening the cooking time and saving energy, you can also make a general pot that cannot be made. However, some household accidents that cause improper use and damage and destruction often occur. Here, we summarize the nine taboos in use, hoping to attract your attention.
Avoid improper use. The first is to purchase a pressure cooker selectively. Be sure to select a pressure cooker with a brand name, manufacturer, specification, and qualified quality. Do not purchase fake goods. Pressure cooker from the specification, generally has 20, 22, 24, 26 cm four models. If your family has a small population, you can buy a small number. If you have a large population, you need to buy a large one. But if you consider the thermal efficiency, you 'd better pick a bigger one. Pressure cooker from raw materials, generally divided into aluminum, aluminum and stainless steel. Each of the three types has its own characteristics: light weight, fast heat transfer, low price, and a service life of more than 20 years. However, using it will undoubtedly increase the absorption of aluminum, and long-term use of it will not be healthy. Aluminum alloys are more durable and sturdy than pure aluminum products. Although the stainless steel pressure cooker is expensive, it is heat-resistant, beautiful, not easy to react with acid, alkali, salt in food, and the longest service life, up to 30 years. So, even if you spend more money, you 'd better buy a stainless steel.
Second, do not use it if you do not want to learn it. Someone bought a pressure cooker. If you don't want to learn it, pick it up. This is the most dangerous! When using a pressure cooker for the first time, you must read the instructions for use of the pressure cooker. Be sure to follow the instructions, or ask people who are familiar with it. It can be used without learning.
Do not check before use. During use, you must first carefully check whether the vent holes are smooth and whether the holes under the seat are blocked by residual particles or other food residues. If the food is blocked during use, the pot should be removed from the fire source, forced cooling, clean the pores to continue to use, otherwise the food in use will be sprayed with burns. Check whether the rubber gasket is aging. The rubber seal ring will age after a period of time. The aging rubber ring is easy to leak in the pressure cooker. Therefore, it must be updated in time.
Avoid overlap between the upper and lower handles. The lid handle must be completely overlapped with the pot handle before it can be placed on the stove to cook food, otherwise it will cause an explosion in the pan flying cover accident.
5. Avoid unauthorized pressurization. Some people add weight to the pressure valve without authorization during use, in order to increase the pressure in the pot and forcibly shorten the production time. However, we do not know that the pressure in the pot has strict technical parameters. Ignoring such scientific design is equivalent to joking with our own lives, which will cause serious consequences of People's injury, never take this risk! In addition, if the melting metal slice (plug) on the pot falls off, it is never allowed to be replaced by other metal blocks, and the same kind of new parts should be replaced.
Six should not be full. When using a pressure cooker to put food raw materials, the capacity should not exceed 4/5 of the size of the pot. If it is beans and other foods that are easy to expand, it should not exceed 2/3 of the size of the pot.
Avoid opening the website midway through. During the heating process, you must never open the lid in the middle, so that the food may be hot. Do not remove the heavy hammer or pressure regulating device before the end confirms cooling, so as not to throw food and hurt people. The lid should be opened only after natural or forced cooling.
Do not watch the fire. The use of pressure cookers is very exquisite, especially the fire cannot be spread. After heating, as long as the steam in the pot from the exhaust pipe to a large "hissing" sound, you can reduce the temperature, so that the pressure limiting valve to maintain a light hissing sound until the cooking is complete. This saves both time and fuel.
Jieshierui shovel. The pressure cooker must be cleaned in time after use, especially to check whether there is food accumulation and residue in the safety plug, to keep the appearance of the pot clean, do not use sharp appliances, such as knives, scissors, shovel, etc., to shovel inside and outside the pot, otherwise the pot will easily become convex and concave, or it is shovel out of a horizontal vertical scratch, damage the protective layer.
==========================================
Guide to simple use of pressure cooker:
The pressure cooker is full of fire when it is fired.
After being burned to the Air-jet valve, it is generally replaced with a moderate fire.
Then, please decide based on the specific situation:
Close the valve immediately after the Steam Generator
Converted to fire in about three minutes
That is to say, change to a small fire before the steam is sprayed again.
The fire time is as follows:
Rice porridge for 20-30 minutes
Cook pork ribs for 12 minutes
Boiled corn for 25 minutes
Every time after the fire is turned off
Put the food in a pressure cooker for more than half an hour.
The food made in this way retains its original flavor.
It can make the food worse.
It also ensures usage security.
If not
Don't take down the pressurization valve.
Do not open a pot.
In this way, the food in the pot can be kept fresh for at least 48 hours.
Even in the hot summer.
==========================================
☆Special Note: when using a liquefied gas furnace for comments, boiling water, or other work, always go to the kitchen to check to avoid an explosion accident.
☆Use of pressure cooker: when using a pressure cooker, be careful because improper use may cause an explosion. The usage is as follows:
Wash the food you want to cook and put it in the pot. You must add enough water. The amount of water depends on the amount of cooking. Combine the handles.
Place it on the stove for heating. When the air hole is angry, put the high-pressure valve up, after the sound, to reduce the fire.
The cooking time varies with the cooking time.
The high-pressure valve cannot be opened immediately after the cook is stopped to avoid injury.
After each use, you need to mix clean water with detergent and scrub the pressure cooker (including the pot and outside the pot ).

☆Use of rice cooker: Note: The casing of the rice cooker cannot be washed in water, and only the inner segment can be cleaned with water.
1) wash, add enough water, dry the bottom of the pot with a dry towel, put it in the bread, rotate the left and right, and then cover the lid.
2) connect the power supply. The red light of the cooking will be on. Then press the rice cooker to cook, and the rice cooker will work normally.
3) after the indicator light jumps from the red light to the yellow light, it takes about 15 minutes to turn off the power supply.
4) after the rice cooker is used, take out and clean the rice in the bread, and then dry it with a dry towel.

☆how to use refrigerators:
how to use refrigerators correctly: refrigerators are divided into two layers. Generally, the above is the refrigerating room, and below is the refrigerating room. Refrigerators cannot be shut down or skewed. The distance between things and things is 2 cm. And set the classification. If the refrigerator has Frost, regularly defrost the refrigerator.
for cleaning in the freezer, take out the items first, dry the ice water in the room, scrub them with water, and then dry them with a dry cloth.
for cleaning in the refrigerating room, take out the items first, and clean the room with water. Then, use the water to scrub it again.
the external cleaning method of the refrigerator is the same as that of the refrigerator.
