The high -pressure cooker is also called a pressure cooker, and the pressure cooker is a kitchen pot.The pressure cooker can improve this physical phenomenon through the boiling point of the liquid at high pressure, so that the water can reach a higher temperature without boiling, so as to speed up the efficiency of cooking food.Use it to heat the cooking food above 100 ° C. In high altitude areas, the pressure cooker can avoid the lowering of water boiling point without being easy to cook food.
How to use high pressure cooker
The pressure cooker only shows its advantages and durable in the case of proper use. The pot should be used as follows.
Unused new pots are highly elastic with sealing circles. Please follow the position shown in the arrow, that is, add a small amount of food oil on the top of the pot body and below, in order to facilitate the initial opening and closing.Before each use, clean pot lid, pot body, and handle should be cleaned to facilitate the cover.
2. Put food
When putting food, the food and water must not exceed four -fifths of the pot capacity, and the water or soup must not be less than 400 ml (about two bowls).
(1) Check whether the exhaust pipe is unblocked before the cover, the cover of the block is cleaned, whether the safety valve is intact, and whether the float movement is up and down, and it is in the lower position.
(2) Fix the lid on the pot and fix the pot body, so that the lid is rotated in the direction of the clockwise direction shown in the figure, until the upper and lower handle is completely overlapped. At this time, it is just moved to the working location, and the floating valve has been fully exposed.
After the cover is closed, you can warm the fire. When you see a small amount of vapor discharged from the exhaust pipe slowly, the pressure limit valve is buckled on the exhaust pipe, and then the floating child will rise until the exhaust pipe is "hissing".After qi, you can reduce the furnace temperature appropriately and keep the exhaust until the cooking is complete.
5. Cool, deflation
After the cooking is completed, it can be cooled naturally at room temperature. If you want to consume immediately, you can use the mandatory cooling method (that is, water with water or immerse in water) to reduce the pressure.Lose.
Seeing that the exhaust pipe is discharged without steam, the floating seeds fall, and the cover can be opened in the direction of the counterclockwise.If the floating seeds have not fallen, it proves that the pressure in the pot is still there. At this time, the pressure chain device will play a insurance effect and cannot open the lid. Do not open the lid tough.Apply chopsticks to press down the indicator valve to clear the remaining gas in the pot before the lid can be opened.
Introduction to high -pressure cooker buying points
Should buy new models of well -known brands and high -pressure cookers from the reputable shopping malls; if the parts of the high -pressure cooker are damaged, go to the regular manufacturer for maintenance or replacement; carefully read the instructions before use;, Valve, Circle, Film "5 parts should be well maintained, and the high -pressure cookers that have been used for more than 8 years cannot be used.The biggest difference between high -pressure cookers and other pots is the word "high pressure".Because it has the characteristics of closed and high pressure, it is easy to be familiar, rotten, and time -saving when processing food, and the loss of nutrition and fragrance is relatively small.But as we all know, it is dangerous to heat water in a closed container. Because the steam cannot be leaked, the pressure in the container will be very large, which will easily cause the container explosion.In order to make the pressure in the high pressure cooker is not too high, the "pressure reduction valve" is installed on the high pressure cooker, so that the pressure inside the pot can be leaked from the weakest place set in this artificial setting in time when the regulatory limit is exceeded.
The high -pressure cooker is stamped with high -quality aluminum plates or stainless steel plates, and its working pressure is 80 to 100 kg.When choosing a pressure cooker, in addition to whether the surface is clean, there are alkaline stains, oil stains, and water stains inside or outside the pot., Round, tidy, no pores and residue.
Well, whether it is a good or stainless steel pressure cooker in an aluminum pressure cooker, which mainly depends on the economic strength of the buyer.Because the manufacturing process of stainless steel pressure cookers is difficult, the price is slightly more expensive than the aluminum pressure cooker.However, as far as security performance is concerned, as long as the high-pressure cooker produced by GB13623-92 and GB15066-94 in accordance with national standards can ensure safety.However, one thing must be clear, that is, no matter what kind of high -pressure cooker, the use period must not exceed 8 years, and the consequences of the oversized service must be lost.
According to the annual statistics of the Chinese Consumer Associations complaint department, in 1997, the "quarterly statistical table of major cases of consumer complaints" reported by the provincial and municipal consumer associations in 1997 showed that the high -pressure cooker explosion accounted for more than 20%of the total number of complaints, resulting in 1 death and 7 injuries and large amounts of propertydamage.Statistics of major cases in 1998 showed that the high -pressure cooker explosion accounted for 10%of the total, of which 3 explosions occurred from Sanmen City, Zhejiang.An elderly man named Zhuhe Lilian used a high -pressure cooker to cook porridge. After the rice was put on the fire, it exploded only 8 minutes, causing three fractures and mental disorders in her whole body.A 25 -year -old high -pressure cooker explosion victim was blind because of his eyes and even thought of death.
Comprehensive analysis of the causes of multiple accidents shows:
The pressure cooker is generally the old standard pressure cooker that has been banned from the production and sales of the state, and the pressure cooker of the "over -time service". Of course, there are also cases that users have unclear work principle and safety parts of the pressure cooker.According to the technical supervision department, the design of the old pressure cooker is defective and lacks necessary safe use devices.The old standard (Zby3006-85) has stopped using it since 1993, and enabled new national standards (GB13623-92).However, some pressure cooker manufacturers have not performed according to the new standards, and some have even played new labels on the old pot to deceive consumers.
In a sense, the key to constitute a high -pressure cooker high pressure is the high -pressure cooker glue ring, and the key to achieving pressure decompression is the "pressure reducing valve" and easy melting sheet.
The high -pressure cooker cushion ring is made of rubber as the main raw material, and a variety of additives such as sulfur, anti -aging agent, active agent, filling agent, and color agent were used during processing.In order to reduce production costs, some illegal manufacturers have added some non -food auxiliary agents. During use, they can easily cause food pollution and cause adverse effects on the human body.In order to keep the high -pressure cooker in high pressure, experts suggest that it is best to prepare two rubber rings in the home, one of which is used for cooking oil -based food, which can extend the service life of the other rubber ring by 3 to 5 times.
In addition, during the use of high -pressure cookers, we must pay attention to the performance of the five safety components of "cover, holes, valves, circles, and films".
Cover: The upper and lower handle should be true when the cover is covered, and then open the lid after cooling and cooling.
Hole: Check whether the exhaust holes are unobstructed before use, and the blocking valve should be removed in time.
Valve: The pressure -limited valve must not press heavy objects in use, let alone other items instead.The safety valve exhausted, indicating that the pressure in the pot has been overweight, and the fire source should be turned off immediately or used the micro -fire.
Circle: Wash the pot covering ring after each use, and it should be wet before use. It should be updated immediately when aging, leakage, and deformation.
Film: This is a strictly calculated safety and low melting point alloy tablet. It must not be replaced by any other metal slice; the food residue cannot be attached to the melting tablets to avoid affecting the thermal conductivity.
