How to adjust the grinder?

Different models of bean grinder adjustment methods are different, first of all you need to understand the structure of the bean grinder and the adjustment method of parameters. Do not adjust parameters more than 3 mm at a time. If you frequently adjust the parameters of the bean grinder, then the amplitude of each adjustment should not be too large. With the same amount, smoothing and pressing steps, a 3 mm adjustment is enough to fluctuate the extraction time of coffee by 3-5 seconds.

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.

The most difficult part of adjusting the electronic grinder is that when you adjust the grinding parameters, the distance between the sharpeners will change accordingly, and this change in distance will directly affect the amount of powder produced by the grinder, that is, the time of grinding and powder. For example, if you want to make the grind finer, the sharpeners will be closer together. Suppose that the preset grinding and powdering time is 5 seconds, but because the distance between sharpening becomes closer, the total amount of coffee beans passing through sharpening in the same time will decrease. And vice versa, if the distance between sharpeners becomes longer, the total amount of coffee beans passing through the sharpeners at the same time will increase.

Therefore, when using and adjusting the electronic bean grinder, you must deeply grasp and understand the relationship between the amount of powder and the degree of grinding, because once the degree of grinding is adjusted, you must make corresponding adjustments to the amount of powder. The secret to success is to test the quality of the coffee immediately after each adjustment to ensure that the taste is perfectly balanced.
