Compared with stainless steel liner, ceramic liner is better.

Strong and durable, ceramic-coated rice cookers are made of sophisticated materials and are generally made of some kind of ceramic material that is not afraid of temperature differences between hot and cold. The physical properties of some glass ceramic pots can withstand heat temperature differences of up to 500°C. They can be put directly into ovens, gas stoves, and microwave ovens through refrigerators without being deformed, cracked, or broken, and without losing the glaze and gloss.

The inner pot material is chemically stable and does not easily react with ingredients. There is no odor when cooking rice and soup; the cooked food is more authentic; the rice cooker with a ceramic inner pot has a good stewing effect, and it is equivalent to buying a ceramic rice cooker. Yu bought a rice cooker + a ceramic electric stew pot, which is more cost-effective; it can also save kitchen space for other kitchen utensils.

Conventional liner materials

1. Stainless steel

Mostly used in cheap models, the advantages are wear resistance, high hardness, and cheapness. The disadvantage is that the thermal conductivity is poor, which greatly increases the cooking time and the heat preservation is also relatively poor. Moreover, the stainless steel inner pot is generally uncoated, and it is easy to stick to the pot, making it very troublesome to clean. If you buy a stainless steel liner, try to choose food-grade 304 stainless steel Q material.

2. Aluminum liner

The aluminum liner is also relatively cheap, has the advantages of good thermal conductivity, good thermal insulation performance, and is heated relatively evenly. Because aluminum will release aluminum substances when heated for a long time and under acidic conditions, which can easily enter the human body with food. Therefore, the surface of the aluminum liner is generally coated to prevent direct contact with food. However, long-term consumption may cause coating The layers peel off.

3. Composite material liner

As the name suggests, it is an liner made of a variety of different materials, such as steel, aluminum, titanium, iron and other different alloys as the main body, and then combined It is made of coatings made of silicon crystal, PFA and other materials. The composite liner has the advantages of good thermal conductivity, strong thermal insulation ability, corrosion resistance, wear resistance, uniform heating, and easy cleaning.
