1, aluminum liner: aluminum has uniform heat conduction, easy molding and beautiful appearance, and can be compounded with other metals or alloys. It is the main material of mid-range cookware. However, in the actual use process, the aluminum liner can not directly 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 corrosion resistance and intergranular corrosion resistance.
3. Ceramic (purple sand) liner: Purple sand belongs to pottery and is a safe inorganic material. The inner container made of purple taro is rich in natural iron, zinc, calcium and other trace elements, which is beneficial to human health. The cooked food tastes good, and the surface is super hard and wear-resistant, acid and alkali-resistant, corrosion-resistant and good in heat preservation.
Matters needing attention in the use of rice cookers
1, rice cookers belong to a class of electrical appliances. In order to ensure the safety of use, 250V, 10A single-phase three hole socket must be used for power supply, and its grounding electrode should be equipped with reliable grounding wire.
2. The power plug of the rice cooker is special. For convenience, users should not replace the two-wire plug. If the electric cooker leaks electricity, it will lead to an electric shock accident.
3. Don't use the rice cooker on wood products and flammable materials to avoid accidents.
4. The bottom, edge and electric heating plate of the inner pot cannot collide. The space between the bottom of the pot and the electric heating plate should be kept clean, and no foreign matter can be involved.
5. Before putting the inner pot, dry the water at the bottom of the pot with a dry cloth and put it in the center of the electric heating plate. Do not tilt, otherwise it will cause poor contact between the electric heating plate and the bottom of the pot, which will affect the use effect. In severe cases, it will cause the electric heating element to burn out.
6. The inner pot is specially used for support, and it is not allowed to be heated by other stoves, nor should it be taken away from the pot body to hold rice to prevent the bottom of the pot from being deformed.
