The problem with aluminum pressure cookers, why are pressure cookers all aluminum alloyed?

Fill the pot with one-third vinegar of any kind (white vinegar or fruit vinegar, cheap is fine), add two-thirds of the proportion of water (must cover the blackened part), cover and boil for five minutes, soak overnight, and gently scrape with a cream knife or spoon to remove the blackened bottom.

Mix vinegar or dish soap with water and cook it over low heat for half a day, so that the water is warm but not boiling, and use a wooden spatula or chopsticks to scrape the bottom of the pot regularly, and try a few more times to gradually reduce. If you can't do it, you can use this to steam the rice a few times, so that the rice gradually absorbs and softens the greasy and dregs of the meat, making it easier to wash!

This seems to be really difficult, try it with vinegar, it should be able to heat it, don't forget to slowly plug it with an iron rag.

In terms of raw materials: it is generally divided into two types: aluminum alloy and stainless steel.

Aluminum alloy is more affordable, the surface oxide layer should not be damaged, and it can be quickly cooled with cold water; Ordinary aluminum alloy pressure cooker.

Light weight, fast heat transfer, cheap, alumina layer on the surface to prevent corrosion (avoid damage), can be quickly cooled with cold water, and the service life is calculated according to 1 hour of use per day.

The construction of the pressure cooker:The pressure cooker consists of a pot body, a pot cover, a fusible sheet, a vent hole, and a safety valve.

and seals, as well as other new forms of bleed channels. The fusible sheet is installed to act as a backup safety in case the safety valve fails, and it is made of aluminum alloy material with a low melting point.

Hello dear, the aluminum alloy pressure cooker Wu Lao is very good. Because the weight of the aluminum alloy pressure cooker is relatively light, it can be said that it is easy to carry, and at the same time, it is more labor-saving for women. Moreover, aluminum alloy is a material that conducts heat faster than others, so that we will be faster when cooking, which is conducive to improving efficiency.

Of course, any product has advantages and disadvantages, such as the disadvantages, there is a layer of oxide layer on the surface, which is easy to be scratched and scratched, and the service life is relatively short, generally about eight years. At the same time, you are reminded to wipe the inside of the pot with a dry rag after brushing, keep it dry, and do not use sharp cleaning tools. At the same time, you are reminded to avoid bumps that affect the integrity of the appearance.

Finally, I wish you a happy life and a smooth work in the year of the orange.

Pressure cookers are generally made of alloy materials, and there will be no outflow of aluminum metal, and the impact is very small, so you can use it with confidence.

Boiling water is sterilized at high temperature, just pay attention to be especially careful when boiling water with aluminum alloy pressure cooker, because the pressure cooker is unstable, this air pressure is particularly high, and it is very dangerous when opening the lid, so you should pay more attention to it at ordinary times. If you can, you should go to the hospital for a check-up, and you don't need to worry too much.

Excessive aluminium intake is harmful

Aluminum is a metal element with low toxicity, although it will not cause acute poisoning to the human body, but if the aluminum intake exceeds the standard, it will still cause some harm to the human body.

According to Shenzhen News Network, only 10 15 can be excreted into the body after the human body ingests aluminum, and most of it will accumulate in the body, combine with a variety of proteins, enzymes and other important components of the human body, and affect a variety of biochemical reactions in the body.

The U.S. Food and Drug Administration has determined that the intake of aluminum 5 g (kg·d) is safe, and long-term intake will have a certain effect on calcium ion homeostasis, other active elements, and have certain toxicity to liver, kidney, bone, and nerves.

Hello, it is better not to use an aluminum alloy pressure cooker. Aluminum pressure cookers are harmful to the body and may affect your health. In the process of boiling in an aluminum pot, it may cause aluminum to dissolve in the soup, and there may be poisoning after eating, and people with more serious symptoms may also have nausea and vomiting, so try not to use aluminum pressure cooker in daily life, which can reduce the degree of harm to human health. 

There are several reasons why it is not recommended to use an aluminum pot as a pot...

1.Aluminum is not as thermally conductive as other metals, so it takes longer to reach the doneness of the food when cooking.

2.The chemical properties of aluminum are reactive and can be easily oxidized to form alumina. In an acidic or alkaline environment, aluminium will be silvered and understated, resulting in easy damage to the aluminum pot and not as durable as Fengshan.

3.When using aluminum pans for cooking, food may contain too much aluminum, which is potentially harmful to human health, especially if the aluminium pan is used for a long time.

4.Aluminium cookware is soft and easy to scratch, making it unsuitable for holding or heating some hard foods.

5.After aluminum is absorbed by the human body, it is not easy to be discharged, and long-term accumulation may cause harm to bones, nervous system and other health.

To sum up, although aluminum pots are lightweight and affordable, it is not recommended to use aluminum pots as pots and pans for health and durability reasons.

1. The thermal conductivity of aluminum is not as good as that of other metals. If you stir-fry, in order to avoid destroying the nutrition of the food, you need to heat it quickly, so you generally do not use an aluminum pot.

2. Chemical properties of aluminum.

Very lively. It is easy to be oxidized to generate Al2O3, which will react in an acidic or alkaline environment, so on the one hand, it will destroy the aluminum pot and make the sodium sodium mine not durable, and on the other hand, it will make the food contain a large amount of aluminum compound branches, destroying the trace elements in the human body.

In recent years, due to the publicity of aluminum poisoning, many people are worried that the aluminum in the aluminum pressure cooker will run out and be harmful to the human body. Let's talk about this today.

Pressure cookers have existed for many years as the kitchenware we are familiar with, although in recent years the saying that "you can't cook with aluminum pots" has prevailed, but aluminum pressure cookers have not withdrawn from the market, but continue to occupy an irreplaceable position in the kitchenware industry. There are two reasons for this:

First, the aluminum alloy pressure cooker must go through strict national standard inspection before it is listed, and only those that meet the production standards are allowed to be listed. On the basis of this, the quality of aluminum alloy pressure cookers produced by regular manufacturers must be relatively more guaranteed.

Second, the inner wall of the aluminum alloy pressure cooker has a dense oxide film, which will not dissolve the aluminum under normal circumstances. Regarding this layer of oxide film, the aluminum melting network intends to explain in detail: the aluminum alloy pressure cooker must be anodized after forming, so that the aluminum alloy surface forms a layer of oxide film with a very dense structure, although the thickness of this film is not large, about 10-20 microns in the range, but its hardness is relatively high, as long as the use of bamboo, plastic rice shovel will not destroy the aluminum oxide film, with a flat and smooth metal shovel at the end, as long as it is not deliberately scraped hard, there is no big problem, will not lead to the dissolution or fall off of aluminum.

Therefore, when we use it, if we don't deliberately destroy it, the normal use of aluminum alloy pressure cookers is still very safe.

Maybe you want to ask, can this oxide film still be used if it is destroyed? We learned in middle school that aluminum has a chemical property, aluminum is an extremely active element, and it will be oxidized in the air immediately to form a hard alumina film, thus protecting the aluminum body from continuing to be oxidized, which plays a good protective role. In this way, under normal circumstances, very few aluminum ions run out, so it can be used with confidence.

In the past, pressure cookers were made of aluminum, and stainless steel pressure cookers came later. In terms of strength, stainless steel is higher, but in terms of thermal conductivity, aluminum pressure cookers are much better than stainless steel pots. Both aluminum and stainless steel pressure cookers cannot store seasoned meals for a long time, because salt, vinegar, etc. have an effect on the pan.

The aluminum of the aluminum pot and the chromium and nickel of the stainless steel pot will melt into the meal, and it will have a bad effect on people for a long time.
