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.
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.
Timer
The presence of a
timer in the design of the coffee grinder — a system that automatically turns off the engine after a certain time. In coffee grinders with different designs of the grinding system (see “Grinding system”), the features of the timer also differ. In models with knives, it actually plays the role of a grinding degree regulator (for more details, see “Adjusting the grind”). Models with millstones have a separate grinding degree control, which is independent of the operating time. Therefore, in this case, the timer plays the role of a kind of dispenser — you can set the coffee grinder so that it does not process the entire volume of the loaded coffee, but only part of it. This is useful given that it is freshly ground coffee that is considered the most delicious, and it often makes sense to prepare coffee for 1-2 portions, rather than large volumes.
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.
