How to choose a coffee grinder for home: manual or electric

Depending on the structure of the mechanism of electric grinders come in mills, or rotational (rotary). To select electric coffee for home use, it is necessary to determine the necessary engine power (speed of the process depends on it), the size of the unit and its capacity.

Manual

Manual coffee grinder will appeal to those who are a pleasure to the brewing process itself.

Not everyone will be pleased to 15 minutes, turn the handle of the mill immediately after you wake up and every time before cooking beverage.

But we must pay tribute to the manual model grinder: Thanks to low speed grinding grains she would not come to them the bitterness inherent in overheated coffee. In addition, chafing releases the essential oils that make up the aroma of coffee, and makes the process of cooking rite, which is so important for the true connoisseurs of this noble drink.

Features and types elektrokofemolok

On the mechanics of a coffee grinder with millstones are not different from the classical manual model. The design of these assemblies comprises two steel disc, between which the crushed coffee beans. In fact, the burr grinder - this Electric mills. The electrical devices of this type may be necessary to adjust the freeness. Electric mills usually have 10-15 grinding modes.

blade-type units have high speed milling and are used not only at home but also in catering. Not all fans are coffee connoisseurs, and is therefore not in a position to appreciate the taste of the drink, prepared according to the rules, why fast and powerful rotary grinder gained much popularity. In such aggregates feedstock processed using knives, seated on the rod. The mechanism is rotated and the knives cut through the coffee beans.

The housing of such devices is made mostly of plastic, some expensive models are made of metal. On top of the device is covered with a lid. The motor is located within the housing, and above - bowl grains. The rotary knife is made of stainless steel with a coating and has the form with two propeller blades. It is located on the bottom of the bowl and is rotated by a motor. blade type devices often have a capacity of not more than 120 g The rotary coffee grinder is not the degree of control the function of grinding. For more fine grinding of knives rotation extend, however, to achieve homogeneity of the coffee fractions in this model is unlikely.

Rotor (knife) grinder

Good rotary grinders have additional features that improve the quality of grinding. To get a more uniform milling and mixing to create a device with a beveled bottom. For the same purpose, a system of pulsating rotation, whereby the rotary grinder grinding becomes more homogeneous. Some grinders have two blades, which increases their speed.

Delonghi company models have several grinding adjustment levels. The review of novelties present types of rotary units equipped with protection against overheating function. If a motor overheating, the appliance is switched off automatically, thus preventing its breakdown. Most modern rotary grinders are protected against operating when the lid is opened, which makes them safe to use. The device can not be turned on until the cover is returned into place.

In some models the grinders have a device for winding the cord. This feature makes the device compact and easier to remove for storage in the closet.

The quality of grinding is dependent on the length and speed of rotation of the blades. The more powerful the motor, the faster will be processed grains. The best power for this kind of devices is 180 watts. The higher the power, the greater the speed milled grain, which may lead to charring and appearance of bitter taste.

Advantages of rotary models:

• grain processing speed;
• low cost;
• ease of maintenance;
• from the inclusion of protection.

Disadvantages:

• irregular grinding grains;
• the absence of the dispenser;
• there is a risk of grain to overcook.

Coffee, grind in a rotary unit, you can cook in Turku. But when using the coffee machine, it is desirable to stop the election at the mill model.

millstone grinder

Grinding, millstone aggregate obtained in essentially uniform and can cook in coffee machines and coffee machines of any type. The housing of the device is made of durable plastic, and the compartments are sealed cover.

The principle of operation of the device:

1. When you turn the device to the network with high speed grinders milled grain. The fines fall into the lower compartment from which they can pour into the cup.
2. Shredding occurs raw material between two rotating surfaces made in the form of cones, cylinders or screw. Uniformity grinding in such aggregates depends on the distance defined between two millstones.
3. The fastest and most productive are cylindrical devices, their speed reaches 1400 rpm. Like the knife grinder, they overcook corn that gives the drink a bitter taste. However, the screw and conical models do not have this disadvantage, since they have the speed 3-4 times lower.
4. Capacity millstone grinders significantly higher than rotary. Such devices may have up to 15 grinding mode, which makes it very homogeneous. Power such grinders ranges from 100 to 1000 W, while the best mode - 250-300 watts.

Pros millstone models:

• You can specify the desired amount of coffee grind.
• Many useful features that make use of comfortable and safe.

Disadvantages:

• the device of this type has a higher price.

Millstone may be made of different materials:

ceramic grinders

Feedback from consumers give high-quality grinding of any degree and long retain quality workers with proper care. But pottery is very fragile, so with such a grinder should be handled carefully, avoiding its fall.

Millstones (corundum ceramics)

These grindstones have high strength, provide fine grinding (for "espresso") durable.

Millstone of stainless steel or cast iron

Stainless steel are inexpensive, durable and lightweight, and sometimes have a titanium coating that increases the term of use. Iron cheap, strong, not fragile, but they are rapidly erased, also absorb odors.

Choosing a coffee grinder for home, better to choose an option with a large bowl of grains. These containers are sealed, so you can safely store them in a grain of coffee, without fear that it will lose its taste and aroma. From time to time should only set the number of the resulting flour.

Expensive and advanced models have additional functions: regulation of the degree of grinding, the timer for cup of coffee produced, over-temperature protection, a dispenser device for winding the cord, and others.

The versatility of rotary millstones and grinders

grinders manufacturers provide them with useful features that make using the machine more comfortable, such as:

• device lock function when the cover is removed, providing a safe operation of the device.
• Rotary machines may have blades with double blades, increasing the speed of processing of the coffee beans.
• The sloping bottom for improved grinding quality and increasing mixing.
• Disconnecting device in case of accidental contact with millstones foreign matter (stones or pieces of wood).
• The rotor models to improve the quality of grinding sometimes pulsating rotation system.
• Off function of the unit when the engine overheats. Solid grains strong roasting require prolonged treatment that may cause motor overheating. In this case, the machine will turn off automatically.
• Soundproofing, ensures quiet operation of the device in the hours when people are still sleeping (night, early morning).
• Timer two types - specifies the number of beverage cups and time spent on the preparation of meals. If the set number of cups, whereas the device itself will measure the required quantity of coffee beans.
• Rubber feet which, unlike plastic supports, give better device stability and adhesion to the surface of the table.
• Before purchasing a device, which has an auto rewind the cord, make sure that it works. Cord Length in some cases is also important, especially with a large kitchen area.

What is the best coffee grinder

To prepare the "espresso" coffee grinders are suitable only to adjust the grinding degree, this is due to in that for the extraction of essential oils grinding grains should be as uniform in size fractions. Zhernovoi view of the apparatus is fully automated. To get started you should download coffee beans and adjust the grinding level. The coffee bean grinders with millstones grinding is 15 degrees (from coarse to dust). This eliminates overheating and burning of coffee while working.

In modern coffee grinder millstone type present a lot of useful functions, for example, you can specify a certain number of beverage cups and spoons device will measure of ground coffee. Such grinders bowl volume is much greater than that of the rotor, and is 200-300 grams against 120. While the single serving of coffee is 6-7 grams of coffee (to cook "espresso" cup you need 7 grams). Burr units are suitable for catering establishments and offices, as designed for large volumes of grinding.

If the amount of coffee drunk per day is low and making coffee takes place in Turku, drip coffee maker or French-Press, the you can use the knife grinder, although in this case, the grinding will be uneven and it is likely to overheat a bit of grain. But for the geyser coffee makers and especially the espresso machine, a non-uniform grinding does not work.
