The time when they chose between manual or electric coffee grinders has passed. Manual coffee grinders are rarely used. Now everywhere use a variety of electric coffee grinders. How to choose the one that is most suitable?
On the device and method of grinding coffee beans, electric coffee grinders are divided into:
- rotary (knife type);
- millstone.
Most of the manufacturers of kitchen appliances produce rotary and grinder coffee grinders: Binatone, Braun, Bosch, Bork, Delonghi, Kenwood, Krups, Moulinex, Saeco, Siemens, Tefal.
When choosing an electric coffee grinder, you need to take into account not only the preferred method of making coffee, but also the size and uniformity of grinding the grains, this is important for such drinks as " mocha ", " espresso " and " cappuccino ".
Rotary electric grinder (knife type)
Such a coffee grinder consists of a plastic or metal casing and a compartment for loading coffee beans, on the bottom of which there is an axial rotary knife made of stainless steel. This container is closed with a removable, most often, transparent lid.
Principle of operation:
Grains are poured into the compartment, the lid is closed. When the machine is turned on, the knives rotate very quickly and crush the grains. The degree of grinding is regulated only by the duration of the operation of the knives. That is, the longer the device works, the smaller the grinding will be.
When choosing a rotary coffee grinder, you should pay attention to such parameters:
- engine power from 100W to 270W, the optimum level is 180W;
- container capacity from 40 g to 120 g, which equals 6-18 cups of ready-made drink;
- the material of the grinder body is plastic or metal.
It should be taken into account that the rotor apparatus is not equipped with dispensers, the amount of coffee to be filled will need to be monitored. There are different models of such coffee grinders: with removable bowls, with the function of protection against overheating, with an additional knife for spices, built-in storage compartment, and more.
Important! The rotary coffee grinder can not be used for grinding other products, because:
- The capacity is not very easy to wash, which means that it will affect the aroma of coffee;
- The coffee grinder can fail (especially if grind sugar or walnuts).
Care of the electric rotary coffee grinder is simple. After use, it is necessary to wipe dry the coffee pot, brush away a bit of old coffee so that it does not spoil the taste of the new portion.
Grinder electric grinder
The electric grinder provides the necessary homogeneous grinding of coffee of a strictly defined size. It consists of a plastic body consisting of three sealed compartments:
- transparent compartment for loading grains,
- opaque compartment of the electric mechanism (engine),
- transparent compartment for ground coffee.
The basis of the mechanism is a conical or cylindrical millstone (most often stainless steel or ceramic), by varying the distances between them, the degree of grinding is regulated. Since millstones are hidden inside the shell, the safety of such a grinder is much higher than that of a rotary grinder.
Principle of operation:
We load coffee beans, turn them on, and millstones grind coffee beans at high speed, small particles are poured into the lower compartment.
When choosing a grinder, it is necessary to focus on such parameters:
- power 250-300W;
- capacity up to 300 g;
- up to 15 grinding modes .
In many mill grinders there is a program for the dosage of grinding. You should know that the grinder can not be turned off before the end of the whole cycle of work. Ground coffee in such a coffee grinder is in a removable bowl, which is hermetically sealed with a lid.
Whatever you choose an electric coffee grinder, the main thing is the pleasure of a drink that is saturated with the aroma and taste.
