Is it good that the rice cooker liner is made of fine iron?

The inner liner of the rice cooker is made of fine iron, which is a better material, and the refined iron is not easy to break, and the strength is high, and the aluminum alloy is not good for health.

The inner liner of the rice cooker is made of fine iron, which is also very good, and it is allowed by the state, so you can use it with confidence.

The advantages of the fine iron liner are: large bearing capacity, suitable for ultra-high pressure use, and the disadvantage is that it is easy to rust. Refined iron liner generally refers to the type of liner of the rice cooker, and also includes space black crystal liner, black crystal energy gathering thick kettle, nano black crystal liner, porcelain crystal liner, citrine liner, hard oxygen liner, stainless steel liner, etc.

Summary. Hello dear, my answer to your above question is this: I personally think stainless steel is good.

Iron has several disadvantages: if the inner tank coating is broken to expose the iron layer, the iron gall is easy to rust if it is not properly maintained, and if the body consumes too much iron oxide (that is, rust), it will burden the liver. Pig iron contains some impurities that are easily oxidized to form other oxides, which may be harmful to the human body.

Hello dear, my answer to your above question is this: I personally think stainless steel is good. Iron has several drawbacks:

If the coating of the jujube liner is damaged to expose the iron layer, the iron gall is easy to rust if it is not properly maintained, and if the human body burns and ingests too much iron oxide (that is, rust), it will burden the liver. Pig iron contains some impurities, which are easily oxidized to form other oxides, which may be harmful to the human body.

Stainless steel liner: The best stainless steel liner is made of 304 special plate, 304 stainless steel has excellent stainless steel corrosion resistance and good corrosion resistance.

The ferroalloy liner rice cooker is good.

The ferroalloy inner rice cooker is a ferroalloy with thick walls that lock water, heat is more uniform, and the heat storage is more stable. The inner tank of ordinary aluminum alloy is easy to melt when exposed to high temperature, and the entire inner tank will be uneven when heated, and the temperature difference will be large.

As the direct contact object of rice, its choice has a certain degree of influence on the taste, so it is very important to choose the right liner, at present, the liner of various rice cookers on the market, according to the material is mainly divided into aluminum liner, stainless steel liner, ceramic liner, iron liner, composite liner.

When choosing a rice cooker, the recommended order of preference for the inner tank is as follows: composite inner tank (wide range of products to choose from) Iron inner liner, stainless steel inner tank (small range of optional products) Pure aluminum (choose carefully).

Introduction of different liners:

1. Aluminum liner.

Although the aluminum liner is a very suitable material for cooking, it has a certain damage to the human body if it comes into direct contact, and there are basically no rice cooker products on the market that directly use aluminum liners, and even if there are, they are aluminum-iron or aluminum composite liners.

2. Iron liner.

The rice cooked in the iron liner tastes better, and the durability is very strong, but it is slightly expensive, and the general high-end rice cookers are made of iron liners, and the more famous fine iron liner products include Supor's ball kettle fine iron liner.

In terms of material and stool quality, it is better to have fine iron. In terms of workmanship, it is better to make steel.

Which rice cooker liner is the best.

1. Aluminum liner.

Aluminum conducts heat evenly, is easy to form, is more beautiful, and can be compounded with other metals or alloys. It is the main material of mid-range pots. However, the aluminum liner cannot come into direct contact with food, and must be treated with surface protection.

Techniques such as thinning and stretching are often used in the manufacture of aluminum liners, which maintain a certain thickness on the rim and bottom of the pan, which saves material and makes the liner appear thicker.

Second, the popular word "thick kettle" of the inner tank

The "thick kettle" inner tank refers to the inner tank made of thick metal materials at the bottom and wall of the pot. Because food is transmitted by the inner tank, under certain conditions, the heat transferred is proportional to the heat transfer area, that is, the heat transfer effect of the inner tank is directly proportional to the thickness of the inner tank.

Only when the thickness of the inner tank reaches 3 4mm, can it fully meet the heat transfer channel required for cooking food, and achieve the "Ding food" effect of "rice meat fragrance" of Zhongming Ding Food House. If the thickness of the inner tank does not reach 3 4mm, it cannot be called a real "thick kettle".

3. The popular word "honeycomb" of the inner tank

The honeycomb liner refers to the honeycomb arrangement of the thermal effect pattern of the inner tank, which can make the heat convection more sufficient, and can improve energy efficiency more than the traditional planar liner.

Fourth, stainless steel liner.

The best stainless steel liner is made of 304 plate, which has excellent stainless corrosion resistance and good intergranular corrosion resistance. Generally, the 4L inner tank is made of left and right plates, and the 5L and 6L inner tanks are made of left and right plates. Slightly worse than the first-class stainless steel liner will be processed with 202 plates, and the anti-rust ability of 202 plates is slightly worse than that of 304 plates.

The lower end of the stainless steel liner is made of 201 plates. Because the dissolution of harmful metals of 201 stainless steel that can be purchased in China is generally difficult to meet the national health standards for stainless steel tableware containers, the rice cooker with a very low price of stainless steel liner must be carefully selected.

Fifth, the popular word "double bottom" of the inner tank

Due to the poor thermal conductivity of stainless steel, in order to make up for this shortcoming, a layer of aluminum layer for soaking heat must be laid on the outside of the bottom, and then covered with a layer of stainless steel as the surface layer.

6. Ceramic (purple sand) liner.

Purple sand belongs to pottery and is a safe inorganic material. The inner tank made of purple eye is rich in natural iron and zinc, calcium and other trace elements that are beneficial to human health, and the cooking food has a good taste, and the surface is super hard and wear-resistant, acid and alkali resistance and strong corrosiveness, and good thermal insulation performance.

Summary. Stainless steel liner: The liner made of stainless steel is stable and harmless to the human body, but the thermal conductivity is poor, which is easy to cause the problem of rice paste, rice sandwiching on the edge, and sticking to the pan.

Generally, a good stainless steel liner is made of 304 plate, which has excellent corrosion resistance. At present, the dissolution of harmful metals in most of the 201 plates is difficult to meet the relevant national standards, so do not choose the most inexpensive stainless steel liner rice cooker. 2.

Composite multi-layer material liner: This is the mainstream material type on the market, mainly made of fine iron, stainless steel, aluminum alloy, copper, liner coating or ceramic coating and other materials according to the characteristics of the product itself.

Can you elaborate on that a little bit more?

Stainless steel liner: The liner made of stainless steel is violently vertical, its performance is stable and large, harmless to the human body, but the thermal conductivity is poor, which is easy to cause the problem of rice paste, edge rice sandwiching, and sticking to the pan, and it is more troublesome to clean. Generally, a good stainless steel liner is made of 304 plate, which has excellent corrosion resistance.

At present, the dissolution of harmful metals in most of the 201 plates is difficult to meet the relevant national standards, so do not choose the most inexpensive stainless steel liner rice cooker. 2.Composite multi-layer material liner:

This is the mainstream material type on the market, mainly made of fine iron, stainless steel, Shenwang aluminum alloy, copper, liner coating or ceramic coating and other materials according to the characteristics of the product itself.
