Cleaning of bean grinder

We introduced the effect of producing fine powder on coffee and some techniques to avoid producing fine powder. Among them, the cleaning of bean grinder is a very important point.

When the bean grinder is grinding coffee, it will produce static electricity, which will make the fine coffee powder and silver dandruff adsorb on the bean grinder, so the bean grinder must be cleaned up after use, otherwise the fine powder attached to the interior will be oxidized for a long time, and it will be mixed with fresh coffee next time. Therefore, the fine powder or silver skin must be peeled off with a brush, and the grease should also be carefully removed.

When grinding coffee to produce abnormal fine powder, you must pay attention to whether the blade of the bean grinder has been worn. The worn blade will cause uneven grinding, subdivision and friction heat, etc. The simple home bean grinder is used with low frequency, so the blade wear is not common.

If there is something wrong with the blade of the bean grinder used in the coffee shop, it will affect the quality of the product (that is, coffee), so a new blade must be replaced.
