How to adjust the coffee bean grinding scale which brand of bean grinder is better
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 reach a perfect thickness.
Debugging of electronic bean grinder
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 for 3-5 seconds to observe the coffee powder. High-quality coffee powder should be powdery and gravel. If the coffee powder is soft, like flour, it means the powder is fine. On the contrary, if the coffee powder feels tough and rough, it means the powder is too coarse. When the coffee bean enters the grinder, the blade in the grinder will crush the coffee bean into powder.
It is inevitable that ground coffee will produce heat, but the heat will vary depending on the mechanism of grinding beans. Bean grinders grind coffee beans in two ways: one is to grind coffee beans with two grinding plates engraved with shallow grooves, which we call parallel grinders, and most manual bean grinders fall into this category. The other is represented by the shredder, and the coffee beans are cut by two sets of rollers with sharp blades that bite perpendicular to each other, which is the so-called tapered blade grinder.
It is generally believed that slow grinding with a manual parallel bean grinder will not produce heat, in fact, on the contrary, the type of friction with a disc blade is easy to produce heat. On the other hand, the tapered bean grinder can minimize the friction heat produced by grinding coffee powder. The reason is that the tapered blade is ground quickly with a longer blade process, and the tapered blade takes less time and has a lower heating rate at the same thickness.
