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.
Overheat protection
A security system that protects the coffee grinder from overheating and the associated unpleasant consequences (up to its complete breakdown). When the engine reaches a critical temperature, this system turns it off, preventing the mentioned consequences. This makes operation more reliable.
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.
