How to achieve uniform distribution of powder?

It's actually very simple. After putting the coffee powder into the powder bowl, first gently pat the edge of the powder bowl to make the coffee powder slide to the edge of the powder bowl to achieve the basic cover; then use your fingers or the powder bin lid to move the coffee powder from more places around so that the coffee powder is evenly distributed in the powder bowl.

The use of finger push is more suitable for double-head handles (that is, handles that can make two cups of Espresso at the same time) rather than single-head handles. Because the bottom of the double-headed powder bowl is a flat surface, it requires that the coffee powder should be evenly distributed so that each part of the coffee powder has the same thickness, which is convenient for the control of the pressing power and the overall uniformity. While the bottom of the single-headed powder bowl is not a plane, it is generally a two-step structure from the outer edge of the powder bowl to the center. This makes the central part of the coffee powder thicker than the edge part after the coffee powder finishes forming a plane on the surface, so that although the central part and the edge part are subjected to the same pressure, the compactness is not the same, which has a great impact on the future extraction. Therefore, at this time, it is required that after the coffee powder is evenly distributed, the surface should be slightly concave in the middle (so that the overall thickness of the coffee powder can be kept consistent), and then pressing the powder is easier to achieve a uniform and compact effect. Therefore, it is not suitable to pass by fingers, but it is more suitable to scrape off part of the coffee powder from the middle of the powder bowl to form a concave shape with the lid edge of the powder cartridge.
