How to adjust the scale of manual bean grinder

Situation 1:

When the bean warehouse is full of coffee beans, because the amount of grinding beans is as much as it needs, the quantity will stop, which will cause the grinding plate to be filled with unground coffee beans and coffee blocks at any time. If this is the case, then the fine adjustment must be carried out while the grinder is running, otherwise it is possible to forcibly reduce the distance between the upper and lower grinding plates in the presence of coffee beans between the grinding plates, which will undoubtedly damage the adjustment mechanism. over time, the powder becomes thicker and thicker.

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.

Specific operation steps

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 so that the powder reaches a perfect thickness. 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 most difficult part of adjusting the electronic bean grinder is that when you adjust the grinding parameters, the distance between the knives will change accordingly, and the change of this distance will directly affect the powder output of the bean grinder, that is, the grinding and pulverizing time. 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 sharpening knives becomes larger, and more coffee beans pass through sharpening knives at the same time.
