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.
Number of grinding levels
The number of grinding levels provided in the coffee grinder.
For different cases may require different degrees of grind, see “Adjusting the grind” for more on this. The same parameter determines how many fixed settings are provided in the coffee grinder. The more of them, the wider the capabilities of this device, the more accurately you can choose the option for a particular situation.
Note that this characteristic is given only for models with millstones (see "Grinding system") — it is not relevant for knife devices. In the most advanced models, the number of grinding degrees can be in the dozens.
Display
The presence of
a display in the design of the coffee grinder greatly simplifies the work with the device, allowing you to more clearly monitor the process and mode of operation.
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 ground coffee
The presence
of a separate compartment for ground coffee in the design of the device.
In this case, it is precisely the additional compartment into which the finished ground coffee enters. In other words, coffee grinders with this feature have two compartments: one for beans, the second for the finished product.
The convenience of this function is obvious: the finished coffee comes in its own container, it is separated from the unground product, and the user does not need to look for a separate storage container — he can store the ground coffee directly in the coffee grinder. Many models are even equipped with dispensers (see the relevant paragraph) that allow you to measure out small portions of coffee — this is convenient, for example, when filling the holder of an espresso coffee maker directly from the coffee grinder.
The volume of the compartment for ground coffee
The capacity of the ground coffee compartment provided in the coffee grinder.
About such a compartment, see above. On the one hand, capacity affects the amount of coffee that can be ground in one go before filling the compartment, on the other hand, on the dimensions of the compartment and, accordingly, the entire device. With this in mind, in most models this figure is from 100 to 200 g — this is the optimal value in terms by the ratio of capacity and size. At the same time, for domestic use, you can choose a model with a smaller capacity; and coffee grinders with capacious tanks are convenient, for example, for specialty stores where coffee beans can be ground in the presence of a buyer.
