The better liners of rice cookers are: first, the aluminum liner is better to ensure the uniformity of heat conduction; Second, the stainless steel liner has high durability, no coating on the surface, and 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 pot; Fourthly, the ceramic liner can not only bring oxidation resistance and corrosion resistance, but also has certain heat insulation.

1. aluminum lining

The aluminum liner has good thermal conductivity and easy molding, 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 beautiful. When making this kind of lining, other metals or alloys can be added for compounding. It is a traditional liner material, which is more suitable for cooking. But be careful not to buy pure aluminum liner, try to choose coated one, so that the service life of aluminum liner will be longer and it will not harm human body.

2. Stainless steel lining

The stainless steel liner has high durability, no coating on the surface, high safety performance and certain anti-oxidation and anti-corrosion functions. There is no coating, so the coating will not fall off in the subsequent heat conduction, and it is easy to stick to the pot. Therefore, everyone should soak in water after use, which will be more convenient to clean up. Moreover, it should be noted that the stainless steel liner should be made of 304 food grade stainless steel, which can meet the food grade.

3. Composite multilayer lining

This kind of liner is a fusion of various materials inside, with composite steel outside and non-stick coating material inside, which has good thermal conductivity and will not stick to the pot. Due to the different composite materials, their names are different, such as the common black crystal liner and Tao Jing liner. All these are composite multi-layer gaskets. For the black crystal liner, its surface is made of alloy material with higher strength, which will have higher wear resistance and be easier to clean, while the surface of Tao Jing liner is added with a layer of natural ceramic material, which is scratch-resistant and wear-resistant.

4. Porcelain lining

Ceramic liner is a kind of natural inorganic material, which has advantages in oxidation resistance and corrosion resistance, and has certain heat insulation performance. In addition to cooking, it can also be used to make soup, which can effectively ensure the nutrition in food. Moreover, the cooked food tastes good, which is a relatively safe inorganic material and will not have much impact on human health. Moreover, this material has high hardness and acid and alkali resistance.
