The main differences between spherical tanks and spherical tanks are different prices, different advantages and different materials. 1, the price is different. The price of spherical liner is more expensive than that of spherical tank. Spherical high temperature firing, wear-resistant and scratch-resistant. Technically, there are many processes and the input cost is also high. However, the shape of the spherical kettle has changed, and the technological requirements are not as strict as those in Tao Jing, so the price is naturally cheaper. 2, the advantages are different. The bottom of the spherical tank liner is spherical. In the process of cooking, rice and water will form a circular roll, and the rice will absorb enough water and become more fluffy and soft. Tao Jing is a non-stick paint in the liner, which has good non-stick performance and is very wear-resistant. 3, the liner material is different. In Tao Jing, a layer of ceramic material is attached to the liner and surface treatment technology is carried out; The far infrared heating performance of the rice cooker is enhanced. Rich in various minerals, it is suitable for stewing meat and making soup. The food tastes good, but the disadvantage is that it is not resistant to falling, because this Tao Jing liner can promote the concept of health preservation, and now many electric pressure cookers also use this liner. The ball pot simply changed its shape.
