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.
Adjusting the grind
The ability
to adjust the degree of grinding of processed coffee beans (that is, to set how large beans of the resulting coffee are obtained). A number of characteristics of coffee depend on the degree of grinding — in particular, the brewing time (the finer the grinding, the faster the brewing), taste characteristics (the presence or absence of grounds). In addition, different preparation methods and types of coffee machines require correspondingly different grinds.
In models with a knife (see "Grinding system"), the degree of grinding is adjusted by automatic shutdown after a set time — the longer the device operates, the finer the grinding. With a certain skill, you can also adjust the degree of grinding manually, independently monitoring the time.
In models with millstones, the degree of grinding is adjusted by changing the distance between the millstones, which ensures the best quality and independence of the operating time from the selected settings.
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.
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.
Dispenser
The presence of
a dispenser in the design of the coffee grinder. This device is designed to dispense ground coffee in portions. Most often, this portion is 7 g (the standard for one cup of espresso), however, there are models where the volume of the dispenser can be changed at will. Coffee grinders with a dispenser will be useful for lovers of exact recipes, as well as in cafes, restaurants, etc., where both strict accounting of coffee consumption is required, as well as compliance with each portion of the specified standards.
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.
