Italian Coffee course: a simple Analysis of the reasons why the semi-automatic coffee machine is not dense in milking

A friend asked about the inconsistency of semi-automatic coffee machine, and authentic coffee wrote an article on this problem to make a small analysis. Authentic coffee will analyze the reasons for the inconsistency of semi-automatic coffee machine from four aspects:

Steam head of semi-automatic coffee machine

This first point is mainly written for the household semi-automatic coffee machine. The household semi-automatic coffee machine also has the function of beating milk bubbles, but because of its steam head, the milk bubbles will form big bubbles. It takes a lot of practice to use the household semi-automatic coffee machine to make foam that can pull flowers.

2. Whether the water in the steam pipe is drained before milking

When the steam in the steam pipe of the semi-automatic coffee machine cools, it will become water residue and remain in the tube, so before each foaming milk, please discharge the steam until no water is ejected from the tube. The milk foamed with water will produce large bubbles and make a shrill sound.

Third, the technical requirement of milking is to put the steam head 1ax 2 in the milk instead of all on the surface, which will produce large bubbles.

When foaming milk with a semi-automatic coffee machine, if you do not insert half of the head of the steam pipe into the milk, but foaming directly on the surface of the milk, a large number of large bubbles will be instantly produced, resulting in non-dense foaming of the milk. For the foaming of milk, authentic coffee wants to say that practice makes perfect, and more practice can send out dense milk bubbles.

Fourth, milk reasons

The milk used in the cafe is whole milk, but the quality of milk and milk will be different, and the fat content will be different, so the foaming effect of different milk will be different. Some poor quality whole milk, the foaming effect will not be too good. Now the effect of Guangming milk is also good.

How to solve the problem of non-dense foam produced by semi-automatic coffee machine:

1. Put the pull vat containing milk bubbles vertically and collide with the table, so that the big milk bubbles will burst into small ones. After the big milk bubbles are burst, shake the flower jar horizontally and let the foam rotate and collide, which will also eliminate some large milk bubbles. The dense milk bubbles are as smooth and shiny as the mirror.

2. Use a spoon to scrape off a large layer of milk foam above the foam, leaving the dense foam below.
