The things about the powder hammer-why use a powder press
The powder press is a small appliance that every barista needs to use. The above is a powder press for Viagra personal collection and use.
The powder press (or powder hammer) is one of the most commonly used tools in espresso. So the question is, why use a powder press?
Baristas know that when using an espresso machine, the hot water brewed has a pressure of about 9 atmospheres (of course, this is not a fixed value, there are also 12 atmospheres or higher), the pressure is very high, and when the water penetrates the coffee cake, the water is inert. What is inert is that water will penetrate through the weakest part of the coffee cake, not through the thickest part. Therefore, if you do not use a coffee press to compact and flatten the coffee (to make the coffee powder density in the powder bowl as uniform as possible), the essence of the coffee will not be extracted, or some parts will be over-extracted. That is to say, the main purpose is to flatten the coffee powder in the handle, tamp it, form a flat horizontal plane, better let the hot water extract through the coffee powder, and also to make the coffee powder withstand the huge pressure generated during the extraction of the coffee machine. The force of pressing powder should be determined according to the thickness of coffee powder grinding, and the reference is based on the flow rate of coffee during extraction (extraction time 25±5 seconds). If the flow rate is too fast, the powder pressing force is too light; if the flow rate is too slow, the powder pressing force is too heavy, which will directly affect the taste of the finished espresso and coffee. In addition, everyone's application strength will be different, and there will be a big difference between boys and girls, so it is also necessary to adjust the corresponding strength according to the actual extraction effect. What you need to pay attention to is that powder pressing is only one of the links. There are many factors affecting extraction, such as powder amount, powder thickness, powder cloth and powder pressing. These need to be considered comprehensively. Don't hold on to one point.
The main difference is the shape of the base of the hammer.
Flat: The most common powder press, the bottom is flat 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 3.355MM.
3, C-Flat: belongs to the Euro Curve and Flat synthesis, it is not like Euro's bottom arc, but it is like Euro powder hammer is a height difference, the bottom is horizontal flat bottom, but the edge is arc-shaped, there is a height difference.
Ripple: It is difficult to control, the bottom of the powder hammer is wavy.
5. C-Ripple: On the basis of Ripple, improvements have been made. The bottom of the powder hammer is made into a flat bottom at the edge. There are multiple convex concentric circles in the center. The center of the pressed powder is wavy and the edge is horizontal.
6. AmericanCurve: The arc at the bottom relative to Euro Curve becomes smaller, and the height difference between the highest point of the arc and the edge of the powder hammer drops to 1.661MM.
