True gourmets believe that the quality of an invigorating drink is determined by the time between grinding the beans and making them. To follow this rule, you can’t do without your own coffee brewing device. In the article we will consider the advantages of coffee grinders with adjustment of the degree of grinding.
Story
From time immemorial, a coffee drink represented the culture of different nationalities. Historical facts show how this entrenched tradition lived in the minds and hearts of many people. Initially, the grains were ground in a mortar using a pestle and mallet. The first devices for grinding coffee beans were made of stone and wood. Such options made it possible to prepare coffee only coarse grinding. Ancient coffee makers were used by the Arabs to prepare the drink in an oriental way.
Time passed, and human progress came to such an invention as special millstones for grinding coffee beans. By the way, they are the prototype of the first manual device of the coffee grinder. The design consisted of two millstones, between which a screw was mounted to adjust the distance. A funnel for grains was also located between them. One millstone was fixed in place, and the second was rotated with a handle. The smaller the distance between them, the easier the grinding of coffee was. Some modern gourmets believe that a manual coffee grinder mill is the best device for processing coffee beans.
Currently, electric coffee grinders with integrated millstones are produced. Manufacturers of household equipment offer customers a fairly voluminous selection of electric mills. Roller mills are used for the industrial production of coffee drinks. Now the specialized device is called a mill grinder with adjustment of the degree of grinding. All types of millstone household appliances have this feature.
Types
Like all technical units, coffee grinders are divided into types. They are recognized by the presence of a different internal mechanism serving as a mill. In total, there are three types of household device for grinding grains.
- Millstone. In this model, the yield of ground coffee mass is obtained due to the work of millstones. They are professional and domestic, designed for both small and large quantities of grains. Electric and manual coffee grinder designs are available.
- Knife. This type of device is equipped with rotary knives. Coffee grinders are designed for domestic use and operate on the network. Their design allows you to process a small number of grains.
- Roller. It features a special mechanism in the form of metal cylinders, which are horizontally located inside the case. Notches are made on the surface of the rollers. They are only electric and are exclusively industrial.
Views
First of all, all types of coffee grinders are distinguished by the grain grinding system. The drive of work determines their classification. Coffee grinders vary in electrical and mechanical. Working from the network are millstones and knife.
Coffee grinders with adjustable grinding degree, in particular, are equipped with millstones. From the technical side, this option is found to be more convenient and practical. When grinding the grains, the individual particles turn out to be the same in size, and the total mass looks uniform. This is an important factor in the preparation of espresso, since the slightest deviation in this regard will adversely affect the taste of the drink. The principle of operation of this function is described below.
Grain Grinding Adjustment
Due to the fact that the market for household equipment is periodically replenished with more advanced versions of coffee machines, the need arose to create an appropriate grain crushing system. Technical innovations appeared on sale that allow you to follow the process of grinding coffee. Using modern models, every lover of an invigorating drink can choose and set the optimal grain size.
Knife coffee grinders with grinding adjustment work in automatic mode. After the set time, the shutdown button is triggered. The degree of grinding of grains directly depends on the duration of the device. You can get used to using this function manually and press the shutdown button in a timely manner.
In millstone coffee grinders with adjustment of the degree of grinding, the desired result is achieved by changing the distances between the millstones. These models are equipped with a special function that makes it possible to control this process. In an electric mill with conical or flat millstones, the degree of grinding is set automatically. The control system allows you to get a powdery mass with the desired size of microspheres. This frees you from being attached to time and choosing settings.
For each individual cooking method, a different grinding of the coffee mass is required. The taste of an invigorating drink depends on this, as well as the amount of residual grounds. The processing quality is also reflected in the coffee preparation time - the larger the grinding, the longer the brewing time will last.
Knife
Coffee grinders, in which millstones are replaced with knives, operate on the basis of a blender. Grain crushing occurs with the help of a fast-rotating knife, similar to the propeller blades. The specialized device has two compartments: in the first there is a collector engine, in the second - a container for grains, under which a nozzle-knife is fixed. Knife electric coffee grinder with grinding adjustment, not always able to evenly grind the grains. For this reason, they are used mainly in everyday life. Nevertheless, a good quality of the crushing system in combination with an affordable price is attributed to the advantages of some models of the budget option.
Millstone electrical devices
Unlike rotary structures, millstones lack a grinding tank. This kind of mill grinds coffee in the millstones and pours it into the bowl provided for the finished powder. The grinding mechanism may consist of conical or cylindrical millstones-nozzles. They are made of cermet or stainless steel.
When you turn on the nozzle begin to rotate quickly, capturing the grain. Here, coffee is subjected to complex processing, which includes a number of techniques carried out on coffee beans. After crushing, cutting and grinding, the microcrumps achieve a given degree of grinding. Coffee grinders with grain size adjustment are best purchased with tapered millstones. Due to their low rotation speed, in such devices the coffee does not overheat, which means that the drink from it will be tasty and aromatic.
The best choice
Let's try to figure out what you need to pay attention to when we choose a coffee grinder with an adjustment of the degree of grinding. The parameters on the basis of which you can consider the kitchen mill as the best option for preparing an invigorating drink will be indicated below. First of all, we dwell on the technical characteristics that are given in the operating instructions. They are usually represented by the following list:
- engine power (W);
- the rotation speed of the grinding system (rpm);
- number of rotation speeds;
- bean bowl volume;
- the number of degrees of grinding;
- coffee yield (gram / min).
Now let's see what you need to consider when choosing a specialized device. Characteristics worthy of analysis include the following: customer reviews, brand reputation, life, quality of the workmanship, apparatus stability, coffee heating level, grinding uniformity, grinding level, versatility of use, additional options, safety in use, cost.
The best coffee grinders with adjustment of the degree of grinding should cope well with significant loads, have metal or ceramic discs, have high-performance technical qualities and provide the user with the most ground coffee powder. Next, we will review some of these options.
DeLonghi KG 79
Model with a plastic and partially aluminum body. Tanks for grains and powder are transparent, square. An automatic apparatus with a power of 110 W and a capacity of 0.12 kg has one degree of grinding, the possible dose of which is from 5 to 120 g. The powder is homogeneous. When the cover is removed, the power button is locked. There are pens on both sides: one sets the degree of grinding, the second - the required dosage. The design on the rubber legs is quite stable, there is a cell for the cord. An electric coffee grinder with an adjustment of the degree of grinding is small in size, easy to operate and has a quiet sound. In addition, she looks very stylish, black. She also has minuses. This is not a very convenient container and coarse grinding.
Atlanta ATH-272

There is a lock on when the lid is open and a place for winding the cord. Capacity capacity - 65 g, power above average - 180 W, can be used for grinding other products.
VITEK VT-1548
Coffee grinder with a choice of the degree of grinding, portion dosage and operating mode. There are four degrees of grinding. For home use, this is enough and you can not overpay for additional functions. The grinding is uniform. Thanks to the impulsive mode of operation, the electric mill will serve you for a long time, since this idea protects the millstones and the engine from severe overheating. The device is not noisy, compact, made originally. Negative sides: it is difficult to extract the finished powder, it is difficult to twist the cord, it is inconvenient to care for the unit. Manual intervention during operation of the device is not allowed.
Mechanical
Manual grinders are usually made of wood or metal, most often with a square body. There are round models for finely chopping grains.
Product grinding is carried out between static and dynamic millstones. By rotating the knob or micrometer dial, the user independently adjusts the required gap between the millstones. To set the degree of grinding, you need to unscrew the screw located on the handle and adjust the nut located under it.
The advantage of a mechanical device is that the resulting mass does not overheat and retains its taste and unrivaled aroma. The disadvantage is low productivity and substantial dimensions. However, this is a special option for gourmets who make the preparation of a coffee drink a tradition.
The following models are distinguished by their strength, ease of use and compactness: Kaiserhoff 0003, Bekker BK-2521, Empire EM-2361. It is worth noting that they are not particularly popular.
