The most basic machine foam diagram:
Insert nipple obliquely into milk jug.
The nipple should be positioned between the rim and center of the jug, and the nipple must be facing a large area of milk so that the milk can be beaten up.
Remember not to insert the nipple too deep, and with the increase of milk foam, slowly increase the height of the nipple, nipple and milk depth always maintain 0.7 cm position.
