Coffee own milled in a coffee grinder, it is considered more fragrant, crisp and useful to create a beverage. There are many subtleties selecting the right model. How to choose the electric type grinder for home, explained in detail below.
Mill electric coffee is considered to be the best option for the home. There are also variants of mechanized mills, but they are less popular because of the number of disadvantages:
To save your time and effort, coffee lovers buy electric coffee grinders model. Although they are less efficient because they require electricity revenues treat them much more convenient. There are two subtypes of electrical equipment:
- Burr. The mechanism of this grinder is based on two millstones, which are hidden in the machine. Such a model is safer and much greater than the second type, but it also has disadvantages, which are discussed below.
- Rotary or knife. The basis of the device - two knives or a knife, which is open are arranged in a cylindrical container. This version of the budget, but it is considered less professional. In rotary grinders far fewer functions.
To select a subtype can consult with a specialist or acquaintances. But it is best to weigh all the pros and cons of their own.
The following characteristics of both subtypes of electric grinders make the right choice.
Burr
Electric coffee grinder millstone type - it is quite a big unit. Most often Burr grinders are made of metal and glass, plus himself Zhernovoi mechanism is more complex, so these models are more expensive. But Burr device considered professional: they are used by many famous barista.
Millstone more thoroughly and evenly ground coffee grinders contents. They just grind grain, and do not cut them, as is done by the device of rotary type. Grinding enables you to reveal the aroma and taste of coffee, because coffee essential oils stand out due to the pressure of the millstones.
The following are the main advantages of millstones grinders.
Security
The grinding mechanism is hidden inside the casing. Children will not be able to get it.
The uniformity of the grind
The grains are ground uniformly, until uniform. With the convenient form of a container into which are poured the grain along the edges of the container does not remain large particles.
Possibility of adjusting the milled particle size
Standard models allow us to transform virtually grain dust and grind them until the medium or large particles. You can buy and more expensive model that offers more variation grind.
Good taste coffee
Millstone in this type of grinders never overheat, plus milled coffee particles immediately enter into a separate container for collection. Due to this the seeds do not burn, and preserve their original bouquet of flavors.
Ease of use
During the grinding is not necessary to monitor the condition of the grain. There is no need to shake the container to distribute the milled grain is not yet close to the grindstone. It is enough to set the desired parameters, then you can be distracted by their own affairs.
Some models allow Burr also display the number of coffees that you want the user. Depending on the exposed figures will change the amount of free capacity. The user does not need to be alone to measure the number of spoons or use a kitchen scale - you can just pour the grain as long as the limit is reached.
Since millstone type of device more functional and comfortable, they are the highest price category compared to the rotor models. This is the main drawback of machines with a millstone. They are 2 and sometimes even 10 times more expensive than the simplified rotary grinder.
Another drawback - unit size. It occupies a lot of space - as much as a medium-sized juicer or a pressure cooker. Therefore it is necessary to allocate a separate place the device on the kitchen countertop.
rotary
Rotary grinder is largely inferior Zhernov. But multiple disadvantages can be explained by the low price. The average cost of a rotary model - 1000 rubles. But worthy Burr grinders are at least 4000 rubles.
Another advantage of rotary devices when compared with millstones - small size and portability. The rotary machine can be taken with you when country trips, because it weighs less than a kilogram. It fits easily into a travel bag. The device is almost no space on the kitchen table. It can be cleaned daily in the kitchen cupboard and get out only when necessary.
However, shortcomings in the knife grinders much more.
uneven grinding
Knives badly crushed grain, and often in a single serving may show quite different particle sizes.
Deterioration palatability grains
If the user is too long grinds grain, they can burn. Knives are heated during continuous rotation for 20 seconds just after heating the calcined grains strongly. This can lead to drink bitter.
The remnants of coffee on the knife and taste these pieces of grinding
If the blades in the device are not removed, they will adhere to the dust particles, remaining after the previous grinding. If time does not remove them (and clean off the dirt with non-replaceable blades is very difficult), oxide particles, who will give the following milled grains bitter taste.
Inability to find a model with adjustable grinding degree
If the millstones models freeness changed by changing the distance between the grindstones, that can not adjust the grinding size when using a knife coater. Regulate it can only be by their own efforts - the longer clamped "Start" button, the finer particles are obtained as a result.
Difficulty in handling
For the device to constantly monitor: check the grind uniformity, shake the device to the large grains were closer to the knives and milled, to switch off when overheated. Many hard to do it in the morning before work.
As a result, rotor model grinder - is a budget option for those who want a few times to save money on buying a device for grinding.
Also knife machines can be called a "camp": if you want a portable device, a rotary grinder buy a battery.
device Characterization
When you select a unit you need to pay attention not only on the type of grinding. It is necessary to pay attention to many other factors:
- manufacturer,
- materials
- power,
- the level of security.
- and other.
A material for manufacturing the knives / millstones
The material of which are made millstone or knives must not resist corrosion and be durable. Optimal - stainless steel. Such details are durable, strong, and not tupyatsya not oxidized.
Power and Performance
It is usually assumed that the greater the power, the better the electronic device. things are not quite in the case of grinders like this:
- If you buy a rotary device, the lower the power, the better. High power can lead to overheating of the grains. The optimal rate - 150 watts.
- When purchasing patterns attritor may prefer a more powerful model - in this case, the grinding power quality is not affected.
- It is important to pay attention to the number of revolutions (or speed of the grinder). The indicator must not exceed 500 rpm. If you buy a model with a higher grinding speed, there is a risk that the particles are obtained non-uniform.
Tank coffee
On the grinding quality is strongly affected by the reservoir. Optimal reservoir characteristics are different depending on grinding mechanism:
- Attritor grinding. In such a device two reservoirs - main, where the grinding, and further wherein the treated particles have accumulated. Additional should be well attached to the device and does not rattle during operation. A main reservoir preferably selected cone-shaped - then milling uniformity is ensured.
- Rotary grinding. Only one tank. It should be inclined to the grinding is uniform.
Most of the customers prefer glass containers. They are considered more environmentally friendly. But if the house children or animals, due to which the device may often fall, better to buy a model with a plastic container.
device Material
Cheaper options are available with plastic housing, expensive - with metal. Metal more durable and robust. If the budget allows, it should give preference to the metal.
Comparison of the millstones, and the rotary grinders
When purchasing be sure to pay attention to the manufacturer. Top manufacturers of grinders - the company's Redmond, Bosh.
If there is a question about the surcharge for additional features, it is better to spend more money, but to get a fully automated machine. Features such as the adjustment of the grinding, the amounts of portions greatly accelerate and facilitate the grinding process.
