1. stainless steel liner, good thermal conductivity, no trouble of coating falling off. However, the liner made of this material is easy to stick to the pot when cooking, and it is a bit troublesome to clean.
2. Purple sand liner, purple sand is rich in natural iron, zinc, calcium and other trace elements beneficial to human health. The cooked food tastes good, the surface is super hard and wear-resistant, acid and alkali resistant, corrosion resistant and good in heat preservation. Families who like to stew soup like to use this kind of liner to make soup.
3. Composite multi-layer material liner, different manufacturers will adopt different composite methods, but there is no fixed standard for the number of layers of this composite material, depending on the manufacturer's technology. The thermal conductivity of this composite material and the viscosity of the liner are relatively good.
4. The main advantages of iron liner are high thermal efficiency, uniform heating and good heat storage, which is especially suitable for high-power heating and more original ecology.
5. The all-carbon liner has the advantages of fast heat conduction and good heating performance, which improves the far-infrared emissivity of the liner, enables fine water molecules to directly reach the rice core, fully absorbs water to expand rice grains, and makes the cooked rice softer and more delicious.
