In the actual operation of the coffee flower, the production of foam for the flower is particularly critical, this skill training is also the most patient link. We have sorted out the study materials of "how to make milk foam with a coffee machine"!

When operating the steam system of the coffee machine, the degree of steam quality needs to be ensured, which is divided into three times of air spray and one wipe to complete the process operation. After the first air spray removes condensate to get dry steam, the steam volume must be increased at one time when filling the steam, so that the steam can blow the milk in the milk tank to form a vortex. Control the temperature of whole milk and foam, why the effect of foam is not good when the milk temperature is too high? this is because there is a kind of glue in whole milk, which is dissolved at low temperature, and affected by temperature, this kind of colloid will coagulate and change from sol state to gel state. This kind of gel is the skin formed above after boiling the milk.

Steam will affect the effect of milk foam as soon as it produces gelation, so when dispelling milk foam, it should be controlled between 65 and 70 degrees, that is, you should feel the bottom of the vat with your hands and touch it rather hot. but stop the filling of steam when you can hold it for a few seconds, which is why you should use the refrigerator to refrigerate the milk when dispelling the milk foam. It is to increase the time spent in foam, to prolong the heating time of milk, and to control the intake of steam.

The height of the steam pipe mouth from the milk level must be controlled in place, just stuck at the end of the steam pipe mouth engraved position, not too deep nor too shallow. If it is too deep, it will only heat the milk without foam, and if it is too shallow, it will cause the foam to be too big or splash. Also pay attention to the proper lowering of the milk tank as the foam grows, always keeping the mouth of the tube at the same height as the milk. Want to play the ideal milk foam milk selection work is also very important, choose thicker milk, the water content must be small.
