Fans of a fragrant and invigorating drink without a coffee maker can not do. Coffee can be prepared in drip (filtration), capsule , combined coffee machines, in espresso coffee machines, French press coffeemakers, as well as in geyser coffee makers. All these types of coffee makers are designed for home use, that is, it is not about the industrial volumes of the drink.
In Europe, almost every family has a geyser coffee machine, which allows you to brew fragrant coffee for a few minutes. Used, basically, ordinary geyser coffee makers for a gas cooker, that is without built-in heating. There is also a more modern version - a geyser electric coffee machine, which differs from the usual one in that it is not necessary to control the process of preparation of a drink. It is enough to pour coffee into the tank, fill with water, plug in the appliance, and after five minutes enjoy the invigorating coffee.
Principle of operation
The very principle of the action of conventional and electric geyser coffee machines does not differ. The drink is brewed due to the repeated passage of boiling water or steam through a layer of ground coffee. In general, the device of the geyser coffee machine is quite simple - it is a metal vessel equipped with special separators separating the ground coffee and water. Problems with how to use a geyser coffee machine will not arise. Water is poured into the lower tank of the device. When it boils, it rises, passing into the upper tank through a layer of ground coffee. In steam models there is a special high tube, through which steam penetrates into the third upper compartment, where it cools down a little, and then condenses. The preparation of a cup of coffee in such a parting takes no more than five minutes.
Regarding the geyser coffee maker for the induction cooker, the operating principle of the device remains the same. The difference is that the material used to make the case must have the properties of a ferromagnet. For induction cookers, aluminum with a ferromagnetic bottom, cast iron and steel geyser coffee makers are used, and ceramic, glass, copper coffeemakers will not work.
Choosing a coffee maker
When choosing a geyser electric coffee maker, pay attention to its power. This indicator can vary between 450-1000 watts. To buy a large-volume device with inadequate small capacity is not worth it, because one single cup of the drink will have to wait a very long time.
Now about the volume. Note that these coffee machines work only at maximum loading, so be guided by the needs of your family in this drink. In addition, portions of coffee in different countries differ. If in our latitudes the traditional portion is 60-80 milliliters, then the Italians drink from 30-40-milligram cups, so when choosing an Italian coffee maker, its volume, indicated in portions, is divided in half.
Pay attention also to the variety of material and the availability of useful functions. So, the heat-insulating handle will relieve you of the need to use a tack, and the glass top compartment
Additional useful functions include automatic power-off mode, the ability to store hot brewed drink for 30 minutes, the presence of a digital programmable timer, a rotating non-heating base, a light indicator and a metal filter. Manufacturers of geyser coffee makers delight caffeines with models with a cappuccino, a drink strength regulator and an adjustable thermostat.
And finally, some useful tips. Coffee for a geyser coffee maker choose coarse grinding to avoid clogging the filter. And when buying the device immediately find out if there will be a problem to find an additional gasket for your geyser coffee maker, because over time, the elastic band wears out.
