If someone who has used a household Italian machine comes across a commercial coffee machine in the workplace, he may find that apart from the difference between the boiler and the heating method, which makes the steam of the steamed milk bubble much stronger, the number of holes in the steam sprinkler is also different from the shape. Most commercial machines, sprinklers are probably in the form of four holes scattered outward, while the household more professional heat exchange coffee machine is mainly two holes, some are designed into two holes concentrated, but also have a scattered design. A little more advanced machine, a steam machine heated by a heating block, is usually a single-hole sprinkler.

The design of steam sprinkler needs to be considered to 1. The output of steam is 2. Strength of steam

The output of steam will affect the heating rate, and the strength of steam will affect whether the milk foam can be evenly mixed and dense. Generally speaking, the steam output and strength of commercial machines are relatively strong, so the number of holes in the sprinkler can be increased. Even if there are four holes sprayed in four directions, there will be no lack of steam intensity, so that the milk can not tumble evenly, and increasing the number of nozzle holes can also increase the steam output at the same time, so that the heating efficiency of milk bubbles is better to improve work efficiency.

As for the difference between decentralized and centralized, it can be seen from the structure of the steam pipe. Steam is usually sprayed straight to the middle, so in order to spray steam evenly into each hole, it is generally designed to be dispersed, and there are no holes in the middle of the sprinkler, so that the steam can be uniformly directed around. As for the general more professional household machines, the output and intensity of steam are not as sufficient and strong as commercial machines. Therefore, the number of holes must be reduced to concentrate steam output, so that the strength can be increased, so that dense milk bubbles can be steamed, but in this way, the heating efficiency will be lower and the steaming time will be longer. As for centralized and decentralized design, I subjectively think that decentralized design will be easier to use. The dispersed angle is relatively wide, which is beneficial for the air to enter the fresh milk to coat the protein, because it has been reduced to two holes, and there is no need to worry about the strength of the steam.

Professional-grade household machines, in the decentralized two-hole and three-hole use are good, in the steam strength and output can meet the standard, the choice of two holes, you can get strong steam, which is conducive to foam. If you choose three holes, you can get more steam output at the same time and increase the heating efficiency. As for the initial heating block steam engine, in order to smooth the foam, it has to be designed into a single hole, so that the fresh milk has enough strength to tumble. In addition, there is a kind of sprinkler with a hole in the center and a hole around it, which is not recommended because the steam is concentrated in the middle and the surrounding steam is weak. Above the steam output, it is the same as the general dispersion of four holes, but the uneven steam intensity seems to be difficult to control for the tumbling of milk bubbles.
