1, heat distribution: the spherical design of the spherical kettle liner helps to distribute heat more evenly in the pot. In contrast, ordinary liners (such as straight-arm liners) have the problem of uneven heat distribution, which leads to poor cooking effect of rice.
2. Circulating boiling: the structure of the inner container of the ball pot promotes the circulating boiling in the pot, which helps each rice to be fully heated and improves the cooking quality of rice. However, the ordinary liner can't achieve the effect of circulating boiling, which leads to uneven cooking of rice.
