How to adjust the bean grinder?

The adjustment methods of different types of bean grinders are different. First of all, you need to have an in-depth understanding of the structure of the bean grinder and the method of adjusting the parameters. Do not adjust the parameters more than 3 mm at a time. If you often adjust the parameters of the bean grinder, then each adjustment should not be too large. In the case of the same steps of weight, flattening and powder pressing, the adjustment of 3mm is enough to allow the extraction time of coffee to fluctuate up and down for 3-5 seconds.

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.

1, grinding speed

To put it simply, the faster the rotational speed, the larger the cutter head, the faster the grinding, that is, the higher the work efficiency, the shorter the exposure time of the coffee powder from grinding to the extraction, and the more benefits to the extraction, but the faster the rotational speed is, the higher the heat, the powder is very fragile in the high heat environment, and the heat is also related to the grinding time, the longer the blade working time, the hotter the blade is. But the faster the speed can reduce the grinding time, which sounds contradictory in the analysis, which leads to another variable, the size of the cutterhead. So the more expensive the grinding, the closer to the trend of "low speed, big knife head", it is not complicated to understand, there is not much description here.

2, the uniform degree of grinding

This has something to do with the rotational speed, the workmanship of the blade, and the amount of beans, and there are many subtle variables, but in general, in the case of a single variable, the more uniform the rotational speed is, the more uniform the axial symmetry of the blade is, and the smaller the change in the amount of beans is, the more uniform the grinding will be. as for how uniform it is, it is something that cannot be quantified numerically, and can only make a difference in comparison.

The scale is just a reference, different brands have different grinding scales, and the performance of the same model bean grinder of the same brand under the same scale is not exactly the same. it is better to understand it this way: the scale just tells you which direction is thick and which is fine. when you find a suitable powder thickness, the role of the scale will show a little bit. The premise is that only your bean grinder, and can not change the beans, the amount of powder remains the same, the strength of the powder can not be changed.
