How much to adjust the thickness of the bean grinder?-automatic bean grinder calibration

How much is the appropriate thickness adjustment of the bean grinder-automatic bean grinder scale,

Humidity factors play a role not only in sunny and rainy days, but also at different times of the day. Generally speaking, the humidity in the morning and evening is higher than that at noon, so according to the influence of humidity factors, the grinding degree should be thickened in the morning and evening, and finer at noon.

There are many other factors that affect the degree of grinding, including the roasting degree of coffee beans (although coffee beans used by Espresso should use a deeper roasting degree, but sometimes different roasting degrees may be used to roast formula beans for richer taste), blended recipes, and so on. All of the above are the most common and can be mastered by baristas. The previous sections are all about the adjustment of the basic factors in the production process in order to meet that taste standard on the premise of understanding the good taste of Espresso (see the taste of Espresso). There are many places in the world of Espresso that we don't fully understand, and we would like to explore this wonderful world of coffee with you.

Huijia ZD-15 bean grinder in the purchase back, many friends will encounter the problem of the wrong thickness of powder, Chen Lei also encountered, now there are three Huijia ZD-15 bean grinder, if adjusted to the same scale grinding coffee powder thickness is different, for example: the same scale 10, but there are thick, there are fine.

Another situation is that when the scale is set to 1 or 25, the coffee powder grinded from the coffee beans is of the same thickness. The reason is that the grinding plate of the bean grinder is not installed correctly, which may be caused by the fact that we artificially disassemble the bean grinder and fail to install it correctly. The solution to this problem is as follows: even if the bean grinder is installed correctly However, the thickness of the powder still can not meet its own requirements, for example: the powder is adjusted to the minimum, it is not fine enough, or the powder is adjusted to the thickest, not thick enough. The solution to this problem is to remove the dial and screw off the nut in the picture 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. (this passage is transferred from the thickness adjustment of the ZD15 bean grinder of the half Moon Mountain people (a supplement to my playing coffee II).

These two methods can basically solve the problem of coffee powder thickness of Huijia ZD-15 bean grinder. Chen Lei himself has encountered these problems and has been entangled for a long time. Chen Lei sorted out the problem here this time, hoping to be helpful to his friends.
