Only how to adjust the grinding degree of the coffee grinder can make the taste better.

When adjusting the electronic bean mill, we should first grasp the relationship between the amount of powder and the degree of grinding. Thinking that these two variables change with the change of one variable, we need to constantly adjust and test to achieve the best results. the most difficult part of adjusting the electronic bean grinder is that when you are adjusting the grinding parameters, the distance between the knives will change accordingly. and the change of this distance will directly affect the flour output of the bean grinder, that is, the time of grinding and grinding. If you want to make the grinding degree finer, the distance between the sharpening knives will become closer, and there will be fewer coffee beans passing through the sharpening knife at the same time. On the contrary, the distance between the sharpening knife becomes larger, and the coffee beans that pass through the sharpening knife will become more at the same time. In general, the distance between the correct weight, flattened and powdered pressed powder and the outlet should be 5-6 mm. If the height of pressed powder is not in this range, you should try to adjust the powder output of the bean mill (that is, grinding and pulverizing time). When adjusting the amount of powder, the range of each adjustment should be between 0.2 and 0.3 seconds, and after each adjustment, you need to re-test the quality of the coffee. The ordinary electronic bean grinder adjusts the grinding and pulverizing time of the bean mill according to the pre-set amount of powder (please note that the amount of powder is adjusted by the mill based on time rather than weight). If you are not satisfied with the quality of the coffee, the first thing you need to do is to determine whether there is a problem with the amount of powder or the degree of grinding. the debugging of the electronic bean grinder mainly focuses on two variables, the amount of powder and the degree of grinding. These two variables are mutual, change one, and the other will also change to determine the direction of adjustment you need (finer or thicker). Make sure there are enough coffee beans in the warehouse, and the valve between the warehouse and the sharpening knife is opened so that the coffee beans can fall smoothly into the grinding area.

Turn on the grinder for 10 seconds and discard the coffee powder (these are coffee powders that have not been adjusted).

Use the coffee powder to make a cup of coffee to ensure the accuracy of the steps of serving, flattening and pressing powder. Test the quality of the coffee and the extraction time. Constantly adjust the dial to make the powder perfect. Different bean 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 in the habit of checking the settings of the bean grinder, you only need to make very small adjustments. As long as you move the turntable 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.
