If you want to cook a bowl of delicious rice, it is very important for the rice to be heated evenly, but in addition to having enough firepower, the inner pot of the rice cooker cannot be ignored. The thicker the inner pot of the rice cooker, the better the thermal conductivity and the stronger the heat storage capacity. The heat loss is slow, the rice naturally expands more fully and full, and the bottom of the pot is not easy to burn.

1. Ceramic liner

Ceramic rice cookers mostly use ore and sand as raw materials, which are one of the safe inorganic materials. It is rich in a variety of trace elements such as iron, zinc, and calcium that are beneficial to human health. Cooked food tastes good, and the surface is super hard and wear-resistant, resistant to acid, alkali and corrosion, and has good thermal insulation performance. But the thermal conductivity is worse and the heating is slower.

2. Aluminum inner tank

In fact, at present, the mainstream production materials of domestic rice cooker liner are still aluminum. This is because the aluminum liner contains metal aluminum, which conducts heat evenly and saves costs during production. The appearance is also relatively beautiful, and it can be compounded with other metals or alloys.

3. Stainless steel liner

The stainless steel liner has good thermal conductivity, excellent corrosion resistance, and is not easy to rust. There is no need to worry about the peeling off of the non-stick coating. Overall a good choice. However, we need to note that even stainless steel has advantages and disadvantages. The finished rice cooker made of ordinary stainless steel and 304 stainless steel is very different.

4. Composite multi-layer material liner

As the name implies, it is a liner made of various materials, which combines the thermal conductivity of stainless steel and the overall heat-dissipating effect of aluminum. This composite multi-layer material liner is basically used in high-end products.
