Maintenance and calibration of bean grinder-hand coffee grinder

1. The particle size should be uniform.

If it is uneven, the brewed coffee will taste incongruous. The finer the grinding particles, the more coffee ingredients are extracted, and the thicker the particles are, the less ingredients are extracted. In order not to destroy the original aroma of coffee, care should be taken when grinding to make sure that the particles are uniform.

2. Avoid friction to produce heat.

High-speed grinding of coffee beans will generate heat due to friction, which will deteriorate the coffee powder or lose the aroma components of the coffee. Manual bean grinder is especially easy to produce heat, so we should pay attention to slow grinding.

3. Remove fine powder

When grinding coffee beans, it will produce some fine powder, such as mixing it, which will release bitter substances such as tannins when brewing. Fine powder is produced more in the use of electric bean grinder, some electric bean grinder with the function of automatic removal of fine powder, usually can be removed manually. Because the fine powder is lighter than the normal coffee particles, as long as the ground particles are shaken and blown, they can be removed.

In addition to mastering the essentials of grinding, which has an impact on the taste of coffee, it is also very important for the maintenance of the bean grinder; after the grinding is completed, the bean grinder should be cleaned immediately. The above fine powder can be attached to the bean grinder, and the taste of coffee will become worse after repeated use.
