What kind of liner is good to choose when buying a rice cooker, and which kind of liner is the best

The better rice cooker liners are: first, the aluminum liners, which are better to ensure the uniformity of heat conduction; Second, the stainless steel liner has high durability, no coating on the surface, good oxidation resistance and corrosion resistance; Third, the composite multi-layer material liner has good thermal conductivity and is not easy to stick to the pan; Fourth, the ceramic liner can not only bring anti-oxidation and corrosion-resistant effects, but also have a certain degree of thermal insulation.

1.Aluminum lining.

The aluminum liner has good thermal conductivity and is easy to form, and the output heat is relatively uniform, so that the subsequent internal food is heated evenly. The overall appearance of the aluminum liner is also relatively beautiful. When such linings are manufactured, other metals or alloys can be added for compounding.

It is a traditional liner material, which is more suitable for stir-frying. But be careful not to buy pure aluminum liners, try to choose coated ones, so that the service life of aluminum liners will be longer, and there will be no harm to the human body.

2.Stainless steel lining.

The stainless steel liner has high durability, uncoated surface, high safety performance, and also has certain anti-oxidation and anti-corrosion functions. There is no coating, so the coating will not come off in the subsequent heat conduction, and it is easy to stick to the pan. Therefore, everyone should soak it in water after use, and it will be more convenient to clean up.

And it should be noted that the stainless steel liner should be made of 304 food-grade stainless steel, which can meet the food-grade requirements.

3.Composite multi-layer material lining.

This kind of inner tank is a fusion of various materials inside, the outside is composite steel, and the inside is a non-stick coating material, with good thermal conductivity and will not stick to the pan. Due to the different composite materials added, their names are also different, such as the common black crystal liner, Tao Jing liner, etc. , all of which belong to the category of composite multi-layer liners.

For the black crystal liner, the surface of the inner tank is made of alloy materials with higher strength, which will have higher wear resistance and is easier to clean, while the surface of the Taojing inner tank is covered with a layer of natural ceramic material, which is scratch-resistant and wear-resistant.

4.Porcelain lining. Ceramic liner is a natural inorganic material that has advantages in oxidation resistance and corrosion resistance, and has certain thermal insulation properties.

In addition to being used for cooking, it can also be used to make soup, which can effectively ensure the nutrients in the food. Moreover, the cooked food tastes good, is a relatively safe inorganic material, and will not have much impact on human health. Moreover, this material has high hardness and resistance to acids and alkalis.

What rice cooker liner is good.

1. Aluminum liner: aluminum conducts heat evenly, is easy to form, relatively beautiful, and can be compounded with other metals or alloys. It is the main material of mid-range pots. However, in the actual use process, the aluminum liner cannot be directly in contact with food, and the surface must be protected.

2. Stainless steel liner: A good stainless steel liner is made of 304 plate, which has excellent stainless steel corrosion resistance and good intergranular corrosion resistance.

3. 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 a variety of trace elements such as zinc and calcium that are beneficial to human health, and the cooking food has a good taste, and the surface is super hard and wear-resistant, with strong acid, alkali resistance and corrosion, and good thermal insulation performance.

The best and healthiest inner liner of the rice cooker is as follows:

1. Ceramic crystal liner: The rice cooker of ceramic crystal liner is known as a pure natural inorganic, it does not use coatings, will not bring harm to the human body, and has good acid and alkali resistance and strong corrosion, good thermal insulation performance, etc. However, it heats up slowly, has low thermal efficiency, and is easy to break.

2. Composite liner: The composite multi-layer material liner is generally mixed with pure copper, with five layers of different materials from the inside to the outside, which integrates the advantages of each material, has strong thermal conductivity, and is not easy to stick to the pan, but the cost is also relatively high.

3. Black crystal liner: alloy aluminum with a thickness of 2 mm is used, and the oxidation process of aerospace technology is adopted, which not only makes the strength higher, but also greatly improves the wear resistance and non-stickiness.

Rice cooker buying tips.

First of all, according to their own economic strength to choose some excellent brand products, good brands in quality service and after-sales guarantee are good, so that consumers can buy at ease. Secondly, you can choose a rice cooker that combines multiple functions, which can not only save money, but also effectively use the space in your home.

The rice cooker not only has the function of cooking rice, but also can make cakes, and some pressure cookers can cook chicken without water. Mausoleum type.

In terms of material, it is better to have fine iron. In terms of workmanship, it is better to make steel. Which is the best rice cooker liner.

1. The aluminum liner aluminum conducts heat evenly, is easy to form, relatively 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 keep the rim and bottom of the pot at a certain thickness, which saves material and makes the liner look thicker. 2. The popular words "thick kettle" and "thick kettle" liner refer 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" honeycomb liner refers to the thermal effect pattern design of the inner tank in a honeycomb arrangement, which can make the thermal convection more sufficient and improve energy efficiency than the traditional plane liner.

Fourth, the best stainless steel liner is made of 304 plate and slag, 304 stainless steel has excellent stainless steel 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" due to the poor thermal conductivity of stainless steel, in order to make up for this shortcoming, it is necessary to lay a layer of aluminum layer for soaking heat outside the bottom, and then cover a layer of stainless steel as the surface layer, the inner tank with this treatment is usually called "double bottom".

6. Ceramic (purple sand) inner 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, with strong acid, alkali resistance and corrosion, and good thermal insulation performance.
