What is the functional structure of the Italian coffee machine? Accessories for an Italian coffee maker?

Make and cook the handle:

The special tea-making handle of the Italian machine can be turned on the other side of the handle, and then the steel ball in the diversion nozzle can be controlled to control the flow. And this kind of handle can not only make tea, but also can be tested and calibrated, and you can test how long it takes to soak tea before it is the best to drink.

A single diversion nozzle can only make one cup at a time.

Double guide nozzles, can make two cups at the same time.

Bottomless, this can be used to test the ability and skill of filling pressure channel and average pressure. When the filling technique is good, you can see that espresso is concentrated in the middle. The following picture shows what bottomless extraction looks like, and it is obvious to observe the extraction process.

Filter or filter cup: there is a difference in the amount of powder, the two on the left and the right can hold a maximum of 14,16g; the second on the left can only hold a maximum of 7g; the first filter cup on the left can hold up to 21g.

Steam pipe, nozzle head: the most important thing is to make milk foam, such as hot milk foam such as cappuccino or latte. Most of the outlet holes of the nozzle head are four-hole and five-hole, such as the upper Expobar Markus is four-hole, while expobar OFFICE LEVA 1GR is single-hole.

Filler: there are many kinds of fillers on the market, the surface of the filler is divided into plane and arc surface, and the arc surface has the difference between sub-European arc and beautiful arc, even now some people do concentric arc surface. In addition, there is a kind of constant pressure filler, which has a larger upper disc and a smaller lower disc, and the large disc will get stuck on the upper edge of the filter cup when filling, resulting in a constant pressure effect. In the end, there are differences in material, weight, grip length, and so on, and in fact, it depends on your personal preference, but no matter how you choose, the key point is to find one that is the most convenient for you. Because only a handy filler can evenly exert pressure and use appropriate strength to complete the filling action, it will not cause the problem of excessive or insufficient extraction.
