The solution of electrostatic flying powder sticking powder in bean grinder how to eliminate static electricity in coffee grinder

I believe that when grinding beans, we will encounter the phenomenon of coffee powder flying around, or sticking in the powder mouth or powder cup. People are also very upset when they encounter this kind of situation, which is mainly due to static electricity and grease. Let's talk about how this happened in the front street.

In a nutshell, let's start with the issue of fat, which often occurs in deep-baked coffee powder. After grinding the deep-roasted coffee, a considerable number of coffee powder will "stubbornly" stick to the powder cup, no matter how can not shake down. The grinding of shallow roasted coffee beans does not have the phenomenon of sticking powder, so we can basically judge the problem of coffee oil.

Deep-roasted coffee bean body expansion is relatively strong, the structure is relatively loose, with the continuous discharge of carbon dioxide, oil also oozes out of the bean surface. So the beans look a little "wet". Some friends think it's water, and the coffee beans are damp, but in fact it's oozing oil from deep-roasted coffee. After the oil-flavored deep-roasted coffee beans are ground into coffee powder, some coffee powder is mixed with oil on the edge of the powder cup, which is difficult to pour out by shaking or slapping. A relatively simple solution is to connect the coffee powder with a powder cup and gently scratch the inside of the powder cup with a small spoon or stick, so that the coffee powder glued to the cup will fall off. The second reason is static electricity. In a dry environment, coffee powder is more likely to produce static electricity. If the powder receiver is not in contact with the powder outlet, the coffee powder will easily fly out of the powder outlet, that is, the flying powder phenomenon, and there will be a lot of coffee powder sticking to the powder outlet and the cup mouth of the powder receiver. So sometimes it is found that the number of grams of coffee powder is less because the coffee powder is adsorbed on the powder outlet of the bean grinder because of static electricity.

Some new electric bean grinding machines are equipped with antistatic tablets, which can effectively slow down the phenomenon of flying powder and sticking powder. But most small electric bean grinders and hand grinders do not exist, such as the small Fuji used in front of the street, the problem of flying powder and eating powder has always existed; the bottom of the knife plate of hand-ground coffee beans is covered with coffee powder. Now you have the same situation when grinding beans, so you can try this simple method, that is, stick some water with a small spoon (stick), and then wait for the spoon (stick) to remain moist but not dripping. Stir the coffee beans with a spoon (stick) and grind them in a bean grinder. This can effectively reduce the generation of static electricity.

Of course, this practice also has risks, for example, carelessly put too much water, it is easy to make coffee powder caking, damp, long-term, will also make the knife head rust. Therefore, Qianjie suggests to use it only when the weather is very dry and easy to produce static electricity, and the amount of water should be properly controlled. As long as the spoon used for stirring does not form water droplets, there will be almost no problems.
