1, repeatedly open and close the steam pipe for several times to vent the water and stolen goods in the steam pipe and clean the steam pipe;

2. The milk in the milk tank should not be less than 1/3, otherwise it will not foam, nor should it be more than 2/3, because the volume of milk will increase by about 1 times after it is foamed;

3. Extend the steam pipe into the bottom of the milk cylinder;

4, turn on the steam, the general situation will not be adjusted to the maximum, but the specific situation depends on the amount of milk in the milk tank;

5. Move the milk tank down slowly until you hear a crisp and rhythmic "yi yi" sound in the milk tank;

6. When the milk is heated to about 65 ~ 75℃, that is, when the hand holding the milk cylinder feels that the milk is hot, turn off the steam while lifting the milk cylinder upwards, and then move the milk cylinder away from the steam pipe;

7. Clean the steam pipe immediately to prevent milk fat from condensing. When we send milk bubbles for the first time, we can try to beat clean water several times, and then experiment with milk. Finally, we must always remember that beating milk bubbles is a process of exercise, and we must rely on our hearing to beat the most delicate and dense milk bubbles by constantly moving the milk tank.
