1.Flat: the most common powder press with a flat bottom at the bottom.

2.Euro Curve: the bottom of the powder hammer is arc-shaped, and the highest height difference at the edge of the powder hammer is in 3.355MM.

3.C-Flat: it belongs to the combination of Euro Curve and Flat. It doesn't have a curved bottom like Euro, but like Euro, the pink hammer has a height difference, the bottom has a horizontal flat bottom, but the edges are curved, and there is a height difference.

4.Ripple: it's hard to control. The bottom of the powder hammer is wavy.

5.C-Ripple: improved on the basis of Ripple, the pink hammer is made into a flat bottom at the edge, with multiple raised concentric circles in the center, and the pressed powder center is wavy and the edge is horizontal.

6.American Curve: relative to the bottom Radian of the Euro Curve, the height difference between the highest point of the arc and the edge of the powder hammer is reduced to 1.661MM.

Generally speaking, the process of pressing powder can be divided into two steps, first pressing once, gently tapping the edge of the powder bowl, and pressing powder for the second time. This is now a more common way of pressing powder (of course, there are other ways). The effect of pressing powder is that pressed powder is tight, and the surface of pressed powder is flat and horizontal. How can such a result be achieved? In addition to the need for many exercises, the two steps of powder pressing are also required.

The first time you press the powder, you need to press it gently. Some say it is heavy pressure, in order to make the coffee powder compact to form a good pressed powder foundation. First of all, heavy pressure can indeed form a good pressed powder foundation (just like laying a foundation, you must have a good foundation before you can build a solid house). But the heavy pressure also has a downside: if the heavy pressure is not well controlled, the surface of the basic coffee pressed powder is likely to be not flat but inclined, so that no matter whether your second powder pressing is light pressure or heavy pressure, you can not correct such noodles. Second, after the first heavy pressure, only a foundation is formed, but the interior is not the most ideal compact state (otherwise only this time pressing powder is enough, and the rest of the action is superfluous), so if light pressure is used when pressing powder for the second time, it is difficult to exert enough influence on the internal coffee powder, if heavy pressure is used, it will destroy the foundation that has been formed, and is not conducive to meeting the requirements of pressed powder. And the first time to press the powder to take light pressure, will reduce these bad effects. With a little pressure, the coffee powder becomes a little tighter, so that the surface of the coffee powder becomes smooth. The act of tapping a powder bowl between pressing powder. The main purpose of this action is to make the coffee powder adhere to the inner wall of the powder bowl fall down (otherwise, when making the extraction, these powders can easily be soaked and stuck to the inner wall of the outlet head, forming black dirt over time). Some people are used to knocking many times, some people are accustomed to knocking on the lower part of the powder bowl, and some people are used to knocking hard at once, which are all bad. First of all, the coffee powder just adheres to the inner wall and can be dropped by tapping it gently, so there is no need to hit it many times or use a lot of strength. Second, although tapping on the bottom of the powder bowl can also make the coffee powder fall, this action can also have a more serious bad effect-- making the internal coffee powder move. Pressed powder, which has been slightly tightened by light pressure (although it may not be visible on the surface), it is difficult for the powder to correct such a mistake. Therefore, the action of tapping should be gentle, and it is best to control the number of knocks within three times along the edge of the powder bowl.
