Power
The maximum power consumed by the device during operation. In coffee grinders, productivity is primarily associated with this parameter: the higher the power, the faster the grinder handles with the task (ceteris paribus). The suitability of the coffee grinder for working with solid products also depends on the power — more powerful models are better suited for these purposes.
Buying powerful models for everyday use in life is hardly justified: they are expensive, and the time savings are small. But in the professional sphere (for example, in a cafe), where the speed of preparation is crucial, high-power coffee grinders are very useful.
Removable bowl
The presence
of a removable bowl in the design of the coffee grinder.
This feature is found mainly among knife-type models (see "Grinding system") — it is most relevant for them. Thanks to this bowl, the unloading of ground coffee is greatly facilitated: instead of turning the entire grinder over, it is enough to remove the working container and pour the finished product out of it. Also note that the bowl is usually removed along with the knives — this, in turn, is convenient for cleaning and washing the device.
Additional bowl
Availability of
an additional bowl in a set of delivery of a coffee grinder.
This function, by definition, is only found in models with an removable bowl (see the relevant paragraph). An additional bowl is highly desirable if the grinder is planned to be used not only for coffee, but also for other products — especially if these are products with strong, difficult to remove smell (for example, spices). Also note that the auxiliary container can be equipped with more powerful and stronger knives, which do not grind as thoroughly as the main ones, but can easily cope with large volumes of contents and solid products.
