Hand bean grinder scale thickness which is good, how to clean, which brand is good to use

The specific steps for adjusting the bean grinder are as follows:

1. Start to adjust the grinding parameters after determining the adjustment direction (coarse or fine). Make sure there are enough coffee beans in the warehouse, and make sure that the valve between the warehouse and the grinding knife is opened so that the coffee beans can fall smoothly into the grinding area.

two。 Start the bean grinder, run for 10 seconds, and throw away the ground coffee powder (these are unadjusted coffee powder)

3. Make a cup of coffee to ensure the accuracy of the steps of serving, smoothing and crushing.

4. Test the quality and extraction rate of coffee

5. Repeat the above steps until the quality of the coffee is perfect.

About adjusting the electronic bean grinder

When adjusting the electronic bean grinder, you need to consider two variables: the amount of powder and the degree of grinding. Adjust any variable, and the latter will change accordingly. The ordinary electronic bean grinder adjusts the grinding and pulverizing time of the bean grinder according to the preset amount of powder (please note that the amount of powder is adjusted by the mill based on time rather than weight). If the quality of the coffee is not perfect, 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. 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 too high or too low, you need to adjust the powder output of the bean grinder (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 you need to re-test the quality of the coffee after each adjustment. If the pressed pressed powder is highly qualified, but the extraction time of the coffee is still too fast or too slow, then you need to adjust the grinding degree of the coffee. When adjusting the degree of grinding, make sure that the range of each adjustment does not exceed 3 mm. After each adjustment, throw away the first 2-3 pulverized by the bean grinder to ensure that the grinding degree of the coffee powder used during the test is fully adjusted. After testing, continue to adjust the grinding parameters according to the results.

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. For example, if you want to fine the grinding, the distance between the sharpening knives will become closer. Suppose the preset grinding and pulverizing time is 5 seconds, but as the distance between the sharpening knives becomes closer, the total amount of coffee beans passing through the sharpening knife will be reduced at the same time. And vice versa, if the distance between the sharpening knives becomes longer, the total amount of coffee beans that pass through the sharpening knife will increase at the same time.

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