After the milk foam is finished, there is no rush to pull flowers, but pour the milk in the milk jar into another milk tank, and then carry on the flower drawing production! This is a scene that we can see in many coffee shops.

And there is a technical term for this scene in the industry, which is often shared in the front street-"da cylinder".

What is the effect of dumping the cylinder? Like the production of most products, the coffee flower also pays attention to the quality of the material and the skill of operation, and the action of turning the cylinder can not only improve the quality of the material at some time, but also help the pattern to take shape more easily. Let's talk about the quality of the materials in front of the street! Since it is a pattern drawn with milk foam, then the material here naturally refers to milk foam!

The so-called milk bubbles are essentially numerous small bubbles formed by the protein of milk (mainly) wrapped in steam. Technology aside, the more delicate and slippery the foam we use when drawing flowers, the easier it is to draw exquisite and complex patterns! But very often, because of some mistakes, the milk foam is not delicate enough to make a good-looking pattern! For example, there are mistakes in the process of operation, resulting in bad foam, many big bubbles, and the whole is very rough; or it is too thick, resulting in poor mobility; or it is placed for too long after discharging, resulting in milk foam caking, layering with milk, can not be used!

So at times like these, reversing the cylinder will be a very good choice! Because the inverted operation will have an impact, the existence of this force will bring three optimizations to the milk bubbles: first, the milk bubbles will be brought into the milk and re-integrated; second, the impact will cause a lot of rough bubbles to be broken, leaving only solid small bubbles; third, caking, hardened milk bubbles will be washed away.

After optimization, milk bubbles can restore fluidity, and because of rough bubbles, caking bubbles disappear, the whole is more delicate, simply not too suitable for flower pulling!

Why can inverting the cylinder reduce the difficulty of flower drawing? From a literary point of view, flower drawing is a process of painting on a "canvas" called grease using milk foam as a pigment. But if you want the foam to float on the grease surface and form lines, then the cylinder must be tilted to a certain extent, so that the nozzle is infinitely close to the liquid surface, so as to reduce the impact and let the foam float on the surface. In other words, the flower jar plays such a role as a brush in this "studio".

In addition to tilting the flower jar, increasing the amount of milk during fusion to make the liquid level rise is also a skill commonly used by baristas. As long as there is more fusion and the liquid level has an appropriate height in the cup, then even if you do not need too much tilt to pull the vat, the cylinder nozzle can be close to the liquid level. However, this technique can only be satisfied with the production of some basic patterns! If it is some need for embossing or more complex combination patterns, then we can not blend too much, because this will reduce the space to draw! So at a time like this, cylinder reversing will be very worthwhile to apply! Because we can maximize the tilt angle of the milk tank by limiting the amount of milk and using a large milk tank to make a more complex flower pattern! Many friends may ask, why not just use a large-capacity flower jar to pass away the milk? Isn't it easier to do that?

That's true, but a large-capacity milk tank will need more milk because of the increase in space. However, the amount of milk we need to pull flowers is far less than that needed by a large milk tank, so it is a way to have the best of both worlds by pouring it into a large milk tank after it has been disposed of in a small one. But what we need to understand is that the action of reversing the cylinder also needs to be fastidious! For example, it should not be too high, or it will produce extra bubbles; it needs to be put into use soon after pouring, because its defoaming speed will be faster!
