If there is no foam, when we pour milk into coffee, they are not immediately evenly mixed with each other. Although in detail there are still micron-sized particles inside the two liquids, these particles are not close to each other, and the particles account for only a small part of the liquid and do not have the stability of foam. Therefore, the interface of the mixing of these two kinds of liquid is not only because the internal liquid flow is very unstable, but also the interface will soon become blurred because of the diffusion. the choice of the pattern milk tank that cannot be made into a flower is mainly the capacity and the shape of the cup mouth, which determines your use and the amount of coffee cup you produce, while the shape of the cup mouth determines whether you need to pull flowers or make a traditional cappuccino. Choosing a milk tank that is easy to use can not only improve the quality of the foam and the appearance of the coffee, but also effectively reduce the loss and waste of milk.

① material

The milk tank is generally made of stainless steel, not only because it is strong and durable, it is not easy to deform, but more importantly, the thermal conductivity of stainless steel is better, so we can know the milk temperature in real time through touch. This is very important for baristas, so we rarely choose milk cans made of plastic, glass and so on.

② capacity

The capacity of the milk tank is mainly 150ml, 600ml, 1000 ml, 2500 ml and other mainstream specifications, of which the most commonly used is 600ml milk tank. The milk tank is too large or too small is actually not good for foam, and 600 ml is an ideal tank capacity. But for some coffee shops with a lot of busy business, a 1-liter or even 2.5-liter milk tank is also a way to improve efficiency.

③ cup mouth shape

The shape of the cup mouth is generally divided into three types: short mouth, long mouth and round mouth, among which the short mouth is the most versatile, suitable for making most of the coffee and flower-pulling coffee, and is the most commonly used shape; long-mouth individuals think it is more suitable for making cappuccino, and flower-pulling also has a good performance, but the premise is that you must be able to get used to that cup mouth shape; round mouth is the rarest, it is said that more levels can be pulled out when pulling flowers.

Choosing a suitable milk tank will sometimes make you get twice the result with half the effort, and sometimes the size of the milk tank even has a lot to do with the size of your palm, so there is no best, only the most suitable.
