How to adjust the grinding thickness of the bean grinder

Step 1: after grinding with a small amount of beans according to the grinding sample, through observation and finger kneading, roughly adjust.

Step 2: then follow the routine operation, keeping in mind that it must be a routine operation, and the method of operation is almost unchanged for filling and pressing powder. This is to avoid excessive errors in human operation, mistakenly thinking that it is a machine problem in the judgment, and making wrong adjustments.

Step 3: need to summarize the advantages and disadvantages of the machine, we do not say much about the good machine, the powerful machine can be skipped, the general business needs to pay attention to whether the electrostatic treatment of the machine is adequate, the grinding process will produce a large number of friction points, transfer to the powder, whether it is the electric control machine or the manual powder plucking machine, it will cause powder spraying and coffee powder spatter when the powder falls into the powder bowl. Then the actual amount of coffee powder in the powder bowl will make it difficult for us to judge, so most teachers will teach students to weigh it. Let's talk about the old and the new in the second relative. In addition to weighing, the best way for an electric control machine is to have the habit of padding powder, that is, to fill the powder bowl and pad it twice, in order to remove static electricity and better judge the amount of powder ground, which needs to be compared, that is, each production needs to master the extraction state of this cup of coffee in hand, to decide whether the next cup needs to be adjusted.

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.

Any coffee adjustment is the growth and decline of one or the other! Because the Italian base (espresso) emphasizes rich, balanced, generous and fast! The essence of coffee is extracted in a short period of 20-30 seconds. In a very short time, we have to increase the extraction of coffee by grinding its fineness. We have found that the fineness of espresso powder is close to the size of flour (just a metaphor). In the process of making light appliances, why is the powder similar to the size of granulated sugar? Have you found that the extraction time of single coffee is basically around 2~3min, which is a little longer! According to the principle of growth and decline, grinding thickness needs to go in a rough direction (these are some general concepts, and I will discuss it with you later)
