What are the precautions when grinding with a coffee grinder

What are the precautions when grinding with a coffee grinder? This is one of the concerns of many coffee grinder users.
1. After the grinding scale is determined, do not adjust it frequently, because each adjustment requires about 20g of beans to "wash and grind". Over time, the wasted bean money is almost the same as the money to buy a new grinder. Moreover, if it is an unskilled novice, each adjustment may have to be tried many times to adjust the appropriate fineness. Moreover, it is difficult for a single mill to perform well in both the single product and the Italian grind. If you drink both Italian and single products at home, it is recommended to buy a few more mills.
2. Pay attention to cleanliness. The cafe makes a lot of coffee every day. The problem of residual powder does not affect the quality of coffee very much. However, if you make it at home, especially if you only make a cup in one or two days, the residual powder after grinding will greatly affect the quality of the next product. At the same time, pay attention to drying in time when cleaning, otherwise the mold inside can only be replaced. The cleaning method of milled rice circulating on the Internet is also undesirable. The hardness of the rice is too high, which is very abrasive to the grinding disc. The newly bought mill can first grind a few coffee beans for cleaning.
3. Whether the grinding is good can't be observed by naked eyes only, the key is to try it. Sometimes it may seem that the A mill is more evenly ground than the B mill, but the actual coffee made by the B mill is better.
4. Do what you can. It is best to suit you.
