Calibration adjustment of coffee grinder

Calibration adjustment of coffee grinder

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.

Let me tell you the importance of these data. Whenever we adjust the coarseness of the bean grinder to + /-1 scale, the extraction time of coffee will change by 4-5 seconds, and the total weight of coffee will have an error of 10g.

Since we use a large bean grinder, the above changes may not be so obvious on a small bean grinder. But this is enough to prove how important the data is in debugging the bean grinder.

When you do this, most brands of bean grinders on the market will store 60g ground coffee powder. According to our experience, you need to store at least 100g of coffee powder in the bean grinder before you can start debugging the machine, and the debugging effect is more obvious. So, you need to make at least three more espresso before you start debugging the bean grinder, and when you're done, you have to make at least five or more cups of coffee. This is very important! The last thing you want to do is go back to work and retest and debug your machine. If you get the results you want, congratulations! But remember, this is just the beginning. Ensuring the accuracy of the data in the test does not guarantee the perfect quality of your coffee, but it is still a shortcut for you to pursue the best quality of your coffee! If you successfully use this method to calculate the formula for one type of coffee, you can start testing the data needed to make other varieties of coffee, such as drip coffee. Then you will know which data are useful and which are not.
