Box Board Books -Basic Knowledge of the Pot Body

1. Which part of the wok is composed of?

    The wok is generally composed of three parts: pot body, pot handle, and pot handle. The pot handles are parts connected to the pot body and the pot handle.

    There are also some stir -fried woks that are directly installed on the pot.

2. What are the composition of the pot material?

The pots of pots around the world are basically the following:

(1), iron pot. It is also subdivided into cast iron pots (commonly known as raw iron pot) and iron -skinned pot (commonly known as cooked iron pot).

  A, cast iron pot.

B. Iron Pork. Commonly known as cooked iron pot. It is suppressed by the tension stretching.

C. Really stainless pot. It is actually a type of iron -skinned. It is pre -oxidized on the surface of the iron plate, so that the surface of the iron cooker forms a layer of "four -iron film film". The film isolates the iron plate from the air, so the iron plate is no longer regenerated.

    However, after the surface of the iron plate has a "four -iron film film", the food cannot be directly contacted with the iron plate, so the traditional iron pot effect no longer exists.

(2) Aluminum alloy pot.

(3) Stainless steel pot.

(4) Stainless steel-aluminum-stainless steel composite pot. It is made of stainless steel plate and aluminum plate. Compared to the aluminum alloy pot, the advantage is mainly the beautiful appearance.

(5) Stainless steel and copper plate composite pot. High cost and rarely use. Compared with ordinary pots, there is no practical advantage except for the beauty.

(6) Magnesium alloy pot. In recent years, there have been magnesium alloy pots in Europe, America, and Japan. The advantages are mainly light weight, but magnesium alloy pots are not the patent of any manufacturer.

3. Is there any kind of wok body in the world consisting of "patent special materials"?

No. Regardless of any kind of metal or alloy pot, no pot factory has the patent right of the pot material.

       Any manufacturer who claims to be a special pot material, please ensure that "the pot body is composed of patent special materials. Otherwise, the pot factory is willing to pay a fine of 10 million yuan and publish 10 apologies to consumers in the national media."

There are no pot factories (including China and foreign countries) in the world dare to write this guarantee! Intersection

Fourth, why are most medium and high -end woks in the world?

   Among the metal materials, the proportion of aluminum alloy is 2.7, and the proportion of iron (including stainless steel) is 7.8; copper is 8.9.

The thermal conductivity of aluminum alloy is 200, and iron (including stainless steel) is 50; copper is 400.

Due to the lightest weight of aluminum alloy, the heat conduction performance is four times that of iron. The comprehensive advantages of density and thermal conductivity, so 80 percent of the world in the world are aluminum alloy pot. The other 20 % is iron pot and stainless steel pot, as well as a small amount of stainless steel and copper plate composite cooker (expensive. However, copper compound cookers are not patents for any pot factory).

  5. Three -dimensional heat transfer issues

   All pot heat transfer is originally three -dimensional. There is no kind of pot only two -dimensional or one -dimensional heat transfer.

6. Why is the temperature of the "thick bottom and thin wall" pot itself more uniform?

     The structure of the pot is divided into "waiting wall pot" and "thick bottom thin wall" pot.

"Waiting for the wall pot" is that the thickness of the bottom of the pot is basically the same. Due to the low production cost, most of the pots on the market are waiting for wall pots. Ambassador, because the wall of the pot is the same thickness, the thickness of the bottom of the pot is generally thin, otherwise the weight of the entire pot will be too heavy. However, the temperature of the pot body is large, and the thermal conductivity is uneven.

"Thick bottom and thin wall" means that the bottom of the pot is thick and the pot wall is thinner. Because the bottom of the pot is thicker, the heating ability in the horizontal direction is relatively strong. Therefore, the temperature distribution of the pot body is evenly distributed. At the same time, the wall of this pot is relatively thin, so the total weight of the pot is not too heavy.

The body of the digital wok is a thick bottom and thin -walled pot that can be uniformly conducting.

7. What is the mineral health pot?

    It is an ordinary iron pot. A new name is the mineral health pot.

8. What is an ecological energy -saving pot?

   It is an ordinary aluminum alloy pot. If the aluminum pot can be counted as energy saving, then all aluminum pots are the same. If the aluminum pot is calculated, then all aluminum pots are ecological.

Nine, what kind of pot is "superconducting ingredients"?

   It is an ordinary aluminum alloy pot. Just a manufacturer gave a new name for the aluminum pot.

  Although the heating coefficient of aluminum is four times larger than iron (aluminum 200, iron 50). But it is far from superconducting materials. In other words, if the aluminum pot is a superconducting material, then all aluminum pots are superconducting campots.

10. What is a healthy food pot?

    It is an ordinary aluminum alloy pot or ordinary iron pot. Except for the name new, nothing else has changed.

Eleven, what's the matter with no coating pot?

The most primitive pots were originally no coating. Therefore, the simple coating pot is just the most primitive pot.

Because there is no non -stick performance on the surface of the coating pot. Therefore, there were non -stick pots with Tellon coating and non -stick pots with ceramic coatings. That is, there is a coating pot.

However, because the biggest defect of the coating cooker is the short life of the coating layer, it usually falls off slowly from a few months.

Therefore, Tianjin's good intention company launched the "no coating without sticky pot". Not only does it have no coating, but it also has ultra -long non -stick performance, and its service life can reach more than three times that of the coating pot.

Twelve, what is the multi -layer pot?

The current multi -layer pots in the market are true and false.

(1) Multi -layer pot refers to a pan for composite the metal plates of more than two layers. Divided into two -layer pot, three -layer pot, five -layer pot or more layer of pot. The two -layer metal plate is suppressed by the two -layer pot; the three -layer metal plate is suppressed by the three -layer pot; It should be explained that the multi -layer metal plates are produced by a special metal plate factory (it is a multi -layer board for the factory). Essence

The suppression technology of multi -layer pots is generally mastered by hundreds of pot factories in China.

The second-layer pot is generally a "stainless steel-aluminum" composite pot. There are two types of "internal aluminum and outer steel" and "inner steel and outer aluminum".

The three-layer pot is generally "stainless steel-aluminum-stainless steel" composite pot. The pot is characterized by: the surface of the stainless steel is relatively bright and beautiful, and the aluminum thermal conductivity in the middle clip is good. Therefore, to a certain extent, it overcomes the shortcomings of the pure aluminum pot, while the stainless steel pot thermal conductivity has poor thermal conductivity.

The five-layer pot is generally "stainless steel-aluminum-stainless steel-aluminum-copper" composite pot. The outermost layer is copper plate with a special color of copper, which is more beautiful. At the same time, the copper plate is also weak (because the copper plate of this pot is very thin) to improve the uniformity of thermal conductivity. Because the effect of multi -layer pot is only for the lack of thermal conductivity of the appearance and make up for stainless steel (but its thermal conductivity is far less than the aluminum alloy pot. Because it is the layer of thin aluminum in the middle, it improves heat transfer, and it clips it The thickness of the aluminum plate is not as thick as the aluminum plate of the aluminum alloy pot). So it has no particularly magical features, and it is not high -tech.

■ There is also a five-layer pot, which is "stainless steel-aluminum-aluminum-aluminum-stainless steel". This kind of pot is not the first patent; the second is not practical to improve thermal conductivity (because the middle and three layers are aluminum, and the composite of the three layers of aluminum plates is not better than the same thickness of the same thickness).

(2) Fake multi -layer pot. There are still some pot factories, just made a few coatings on the surface of the aluminum pot, and then it is preached that its pot is a multi -layer pot. The role of the coating layer is to improve the non -dipping performance of the aluminum pot, and there is no other effect. (And there are problems that slowly fall off within a year. In particular, it is emphasized that the pot factory does not produce paint, and its coatings are bought. And any coating factory including the United States, Japan, and South Korea did not dare to dare to dare to Make sure the paint does not fall off!

It is particularly pointed out that some international brand -name woks preach that it has a multi -layer of "foreign patents (US or Germany)". According to the Chinese Patent Law: Foreign patents are invalid in China! Intersection Intersection

   The real multi -layer pot is not a high -tech thing. There are no magical functions such as fast heat transfer, slow heat dissipation, and non -dipping pot.

  Thirteen, aluminum alloy pot surface treatment technology is divided into two categories: coating and no coating:

(1) There are coatings. It is also subdivided into organic coatings and inorganic coatings.

● Organic coating is commonly known as Teflon. This is the so -called Korean marble pattern pot, which is also this.

● Inorganic coating is commonly known as ceramic coating. Spray ceramic coatings on the surface of the pot.

※ There is no pot factory in the world to produce coatings. The coatings of the pot factory are all bought.

(2), no coating. It is divided into non -stickless and non -coating, and hard oxidation without coating.

● Hard oxidation without coating has no non -stick performance, which is characterized by low cost. This technology is found by general manufacturers. The coating -free aluminum alloy pot sold on the market is basically this.

● Non -stick coating is a special surface treatment technology. It not only has no coating but also has the characteristics of non -stick pan. The biggest advantage is that the service life is more than three times longer than the coating pot.
