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.
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.
