The secret of grinding coffee beans should be the following two points

The grinding tool for coffee beans is a bean grinder. Bean grinders can be divided into three types:

● family uses manual rotary bean grinder. It is suitable for leisure people with small demand, large particles and killing time.)

● household electric bean grinder. It can grind coffee powder of all kinds of particle size, and it can grind out 6 people at a time.)

● specializes in using electric bean grinder. (for commercial use, coffee powder of more than one pound or less can be ground at a time.)

The following two points should be paid most attention to when grinding coffee beans:

● reduces the heat of rubbing. (grinding heat will cause the aroma of coffee to dissipate early)

The size of ● particles is uniform. (uneven particle size will make it impossible to control the brewing time.)

So if you use a family-style manual bean grinder, you should rotate gently so that it does not produce friction heat as much as possible. To sum up, if the quality, quantity, time and convenience of grinding beans are considered, the electric bean grinder used at home will be the best choice.
