Rice cooker is an essential appliance for household, and to pick a good rice cooker, the right inner liner is also very important, so which kind of material inner liner is better to use？
1. Stainless steel liner
Stainless steel liner is currently one of the most widely used materials on the market, it has a high degree of hardness and corrosion resistance, can effectively avoid the problem of rusting iron liner, and will not produce a bad smell.
Stainless steel liner also has good thermal insulation properties, can maintain the temperature and taste of rice, but also to reduce the loss of nutrients in the food.
2. Aluminum inner liner
Aluminum inner liner has the advantage of fast heat conduction and even heating. The disadvantage is that the aluminum inner liner can not be in direct contact with food, it needs to be coated, and the coating is easy to thin out and fall off. It is the main material for mid-range cookware (please replace the anti-stick coating as soon as possible if it falls off to avoid direct intake of aluminum products causing harm to the body)
3. Ceramic inner liner
The smooth surface of the ceramic liner will not react with the ingredients, which can ensure the flavor and texture of the rice.
Ceramic liner also has good heat preservation performance, long service life, can effectively prevent the loss of nutrients in the food.
However, the ceramic inner liner is heavy and fragile easy to break, so you need to pay attention to be careful to carry and put down gently
Ceramic liner rice cooker, suitable for consumers who have higher requirements on the quality of rice.

Inner liner thickness
The thickness of the liner directly affects the heat transfer efficiency, but it does not mean that the thicker the liner, the more material layers, the better the liner, too thick will affect the heat transfer, too thin will affect the heat storage.
Qualified liner thickness should be between 1.5 mm-3 mm.
Ordinary inner liner is 1.5 mm.
The mid-range liner is 2.0 mm.
The superior liner is 3.0 mm.
Lining Coating
The main function of the liner coating is to prevent sticking of the pan and secondly to prevent the aluminum inner can from coming into direct contact with the rice grains, as mentioned above.
There are three common coatings on the market today, PTFE, PFA and PEEK.
These coatings are ranked: PEEK + PTFE/PTFE > PFA > PFA + PTFE
