1, heating time is too long: milk is rich in nutrients such as protein and calcium, and heating time is too long, which will lead to protein denaturation and scaling, thus causing the bottom of the pot to be burnt.
2, the temperature is too high: when the health pot heats the milk, the temperature is too high, which will lead to the reaction of protein and sugar in the milk, forming lumps, leading to the bottom of the pot being burnt.
3, the milk concentration is too high: if the milk concentration is too high, the nutrients inside will react with the bottom of the pot more easily, causing the bottom of the pot to burn.
