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.
Pulse mode
Possibility of operation of the coffee grinder engine in
pulsed mode when the motor alternates between short periods of operation with pauses. This mode is useful when working with a full load, as well as when processing especially solid products, when the loads on the motor are high: the alternation of pulses and pauses increases efficiency and avoids jamming.
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.
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.
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.
