The change of humidity is also one of the factors affecting the degree of grinding. When the humidity is relatively high, the wet speed of the ground coffee powder is very fast, and there is already a slight humidity when filling the powder and cloth powder. If a fine grinding degree is used, the coffee flavor components have already reacted with the air with high humidity and become messy and impure, while the coffee powder is easier to be compacted and the extraction process is longer, which makes it easier to extract the bad taste and make the overall coffee taste muddy. Therefore, in the case of relatively high humidity, it is not suitable for a finer degree of grinding, it will be better to use a slightly thicker degree of grinding. On the other hand, in the case of relatively low humidity, coffee powder is ground out after contact with the air, the speed of oxidation reaction will also be accelerated, if the coarse grinding degree is used, then the coffee powder oxidation and flavor composition changes together make the extracted coffee taste will be less, lack of depth and mellow feeling, so the degree of grinding should be adjusted appropriately. Of course, after adjusting the degree of grinding, it is necessary to adjust the strength of pressing powder accordingly.

Remove the dial and screw off the nut shown above clockwise. Take off two gaskets (one with a handle) and turn the grinding core: turning clockwise is thickening and counterclockwise is fine. Be careful not to adjust too much. This is a rough tune. And install it. The nut is tightened counterclockwise. It has to be tight. Usually make espresso with a scale between 8 and 12. Of course, you can adjust it to between 2 and 5. Then, when the scale is 25, you may grind the hand punch and the French pressing powder. If it's not thick enough, adjust it outside the scale. The symptom of this problem is that even if the bean grinder is installed correctly, the thickness of the powder still can not meet its own requirements, such as: the powder is adjusted to the minimum, but still not fine enough, or the powder is adjusted to the thickest, not thick enough. The solution to this problem is as follows: the Huijia ZD-15 bean mill is purchased. Many friends will encounter the problem of the wrong thickness of the powder, Chen Lei also encountered, now there are three Huijia ZD-15 bean grinders, if adjusted to the same scale grinding coffee powder thickness is different, for example: the same scale 10, but there is thick, there is fine.

Another situation is that when the scale is set to 1 or 25, the coffee powder from the coffee bean grinder is the same thickness. The reason is that the grinding plate of the bean grinder is not installed correctly, which may not be installed correctly when it leaves the factory. It may also be caused by the failure to install the bean grinder correctly after we have taken apart the bean mill. The solution is as follows.
