Bean compartment capacity
The maximum number of coffee beans that the grinder can hold and process at one time, without "refilling". Note that we are talking about the maximum capacity — a smaller amount of coffee can be loaded into the grinder.
The standard portion of coffee per cup is 5-7 g, and the capacity of a pack of coffee is 100 g. Accordingly, it is worth choosing a model according to capacity, taking into account how much coffee you need to grind at a time. For domestic use, a capacity of 100-200 g is considered quite sufficient, but in professional models designed for coffee shops, bars, etc., this value can reach 1.5 kg or even more. There are coffee grinders that allow you to grind only part of the coffee loaded into them.
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.
Compartment for cord
Compartment for placing the power cord directly in the coffee maker. This feature greatly simplifies storage: when the device is not in use, the cord can be hidden inside the case, and it will not get tangled and interfere. Some models may have devices for uniform winding of the wire, which prevents bending and possible fractures.
