The brands of the mill are different, and the thickness of the powder ground by the same scale marked by each brand of mill is different, which can only be adjusted from your brewing method. At the same brewing temperature, the extraction time can be longer if the powder is coarser, and the extraction time can be shorter if the powder is finer. Basically speaking, regardless of the variety, siphon, hand made fine granulated sugar size coffee powder is more appropriate, semi-automatic Italian machine is required to grind to flour coffee powder

1. Adjust the thickness. Unscrew the top screws, open the handle, place the marking scale in place, and reinstall the handle and screws. This is required many times debugging, because there is no scale on it, you can use it to label it.

2. Put the coffee beans into the grinding disc

3. Shake the handle at a uniform speed and force

4. Remove coffee powder from drawer.

Special attention is paid to: 1, different grinding speed back to affect the quality of the coffee powder generated.

Grind too slowly, coffee powder and air contact time too long will lose more flavor; grind too fast, too high temperature will volatilize more coffee aroma. Moderation. Moderation.

The specific steps for adjusting the bean grinder are as follows:

1. Adjust the grinding parameters after determining the adjustment direction (coarse or fine). Make sure there are enough beans in the bean bin and that the valve between the bean bin and the grinder is open to allow the beans to fall smoothly into the grinding area;

2. Start the grinder, run for 10 seconds, and discard the ground coffee (all ground coffee without adjustment);

3. Make a cup of coffee, ensure that the weight, smoothing and pressing steps are accurate;

4. testing coffee quality and extraction rate;

5. Repeat until the coffee quality is perfect.

About adjusting the electronic bean grinder

When adjusting an electronic grinder, you need to take into account two variables: the amount of flour and the degree of grinding. Adjust any variable and the latter will change. Ordinary electronic bean grinder will adjust the grinding and grinding time of the bean grinder according to the preset grinding amount (please note that the grinding machine adjusts the grinding amount according to time rather than weight). If the coffee quality is not perfect, the first thing you need to do is determine whether the powder or grind is the problem. In general, the distance between the correctly weighed, smoothed and pressed cake and the outlet should be 5-6 mm. If the cake height is too high or too low, you will need to adjust the grinding machine powder (that is, grinding and powder time). When adjusting the amount of powder, the amplitude of each adjustment should be between 0.2 and 0.3 seconds. After each adjustment, you need to re-test the quality of coffee. If the cake height after pressing meets the requirements, but the extraction time of coffee is still too fast or too slow, then you need to adjust the grinding degree of coffee. When adjusting the degree of grinding, make sure that the amplitude of each adjustment does not exceed 3 mm. After each adjustment, discard the first 2-3 grinders from the grinder to ensure that the grinding degree of the coffee powder used in the test is completely adjusted. After the test, the grinding parameters are continuously adjusted according to the results.
