How to adjust the thickness of the bean grinder by hand
The same scale, the same beans, in the case of fine grinding, the powder used overnight has changed? Even after cleaning a large amount of residual powder from the powder outlet at night, there is a phenomenon of increasing extraction time (there is a pressure meter on the machine for reference, and the pressure is really high). Whether the residual powder in the cutter head will have an impact overnight.
The scale is just a reference, different brands have different grinding scales, and the performance of the same model bean grinder of the same brand under the same scale is not exactly the same. it is better to understand it this way: the scale just tells you which direction is thick and which is fine. when you find a suitable powder thickness, the role of the scale will show a little bit. The premise is that only your bean grinder, and can not change the beans, the amount of powder does not change, the strength of the powder can not be changed.
Remember a little trick: when you find the right powder thickness, twist it with your hand from time to time, pinch it, feel it with your body and write it down as much as possible, so that even if you change the bean grinder, you don't have to rely solely on the scale to judge. If you pinch it with your hand, it will be significantly thicker, which can greatly improve your efficiency.
When the coffee bean enters the grinder, the blade in the grinder will crush the coffee bean into powder. The smaller the distance between the blade and the blade, the smaller the coffee beans will be ground into smaller particles. The finer the grinding particles are, the tighter they are, and the more difficult it is for the water to pass through, thus greatly prolonging the extraction time. On the contrary, if the distance between the blades increases, the ground particles will become rougher, the flow of water will be easier to pass through, and the extraction time will be faster.

I never look at the scale, but only adjust the grinding scale according to the grinding degree of the ground powder. Different brands and different grinding scales are different, and the performance of the same type of bean grinders of the same brand under the same scale is not exactly the same.
