Last Updated: 2024/11/08, How to adjust the scale of the Italian bean grinder the debugging of the electronic bean mill is mainly aimed at two variables, the amount of powder and the degree of grinding. These two variables are mutual, and if you change one of them, the other will also change. The ordinary electronic bean grinder adjusts the grinding and pulverizing time of the bean grinder according to the pre-set amount of flour (please pay attention to the basis of adjusting the amount of powder by the mill.

How to adjust the thickness of the Italian bean grinder

The adjustment of the electronic bean grinder is mainly aimed at two variables, the amount of powder and the degree of grinding. These two variables are mutually dependent, and changing one of them changes the other.

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 you are not satisfied with the quality of your coffee, the first thing you need to do is determine whether the problem is with the amount of powder or the degree of grinding.

In general, the distance between the cake and the water outlet after correct weight, smoothing and pressing should be 5-6 mm. If the cake height is not within this range, you should try to adjust the flour output of the grinder (i.e. grinding and flour output 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.

Determine the direction of adjustment you need (finer or coarser). 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.

Turn on the grinder for 10 seconds and discard the coffee grounds (these are unground coffee grounds).

Make a cup of coffee with the resulting coffee powder, ensuring that the weight, smoothing and pressing steps are accurate. The traditional Italian Ristretto method uses a water-to-powder ratio of 1:1 (i.e., 18 grams of ground coffee is used to make 18 grams of coffee) or 1:2 (i.e., 18 grams of ground coffee is used to make 36 grams of coffee), while the regular Italian espresso uses a water-to-powder ratio of 1:2 (i.e.,"Normale"). Test coffee quality and extraction time. Continuously adjust the dial to achieve perfect powder thickness

Different grinders have different adjustment dials, so you should check the model of the coffee grinder and read the instructions carefully to determine the direction and strength of the dial. In general, if you keep checking the grinder settings, you only need to make very small adjustments. Just move the dial scale within 3 mm, you can change the thickness of the powder. Although 3 mm is a very small number, the grinding time of the same coffee beans will change by 3-5 seconds.
