Coffee machine and its features

A coffee machine or coffee maker is an electromechanical device designed to make coffee.

Technique, depending on its type, handles with such tasks as:

• grinding grains;
• brewing a drink of different strengths;
• preparation of several types of coffee;
• portioned addition of sugar, milk or cream to the drink;
• pouring coffee into cups;
• maintaining the required water temperature.

To understand how a coffee machine works, let's first understand what it consists of.

The device of the coffee machine

Dozens of companies around the world produce coffee machines. The most popular brands include:

• De Longhi ;
• Phillips ;
• Bosch.

Devices differ in structure, the number of functions performed, design and size, but the main components and operation algorithms are similar for all.

The most important components in a coffee machine are:

• vessel for boiling water;
• compartment for grains, powder or capsules with ground coffee;
• built-in coffee grinder, but only in a certain type of machine;
• water container;
• apparatus for dosing components;
• custard knot;
• container for waste product;
• department for draining liquid;
• a mini-pipeline through which the liquid moves through the machine;
• capsule holder + filter;
• microchip and electronic control panel in automatic devices.

General scheme of the coffee machine

To understand how to use a coffee machine and learn how to brew a delicious drink, we will consider each type of coffee maker separately.

Types of coffee machines

Coffee making equipment is not only massive units for restaurants and cafes, but also compact models used at home and in the office. They are of the following types:

1. Electric Turk. In its function, it is identical to an electric kettle, but they do not turn off automatically, but outwardly it looks like an ordinary Turk. Models are attracted by their design, the ability to follow the ritual of pouring coffee into cups by hand from a beautiful vessel. But some users are just repulsed by their own intervention: you need to follow the process and turn off the device, carefully pour the drink.

2. Geyser coffee maker. Probably, two decades ago, such a device was in every family. Despite the “age”, and it has already been calculated for centuries, the principle of operation of the technique has not changed. Only the appliance, heated on the stove, was replaced by a coffee maker that connects to the mains. The geyser design is simple:

• compartment for coffee powder;
• water container;
• container for the finished drink.

The preparation procedure is as follows: the heated water, expanding, enters the coffee compartment through the tube, boils, moves up and, under the action of steam, is pushed into the upper reservoir — coffee is obtained.

3. Drip coffee makers. The name of the machine speaks for itself — the Americano drink is obtained by passing a drop of water through ground coffee. The procedure is performed from top to bottom: powder is poured into a special filter, water is poured into a container located at the top of the apparatus. When heated, water expands and evaporates. The steam rises up the tubes, turns into drops, which then fall on the coffee. Gradually, at a temperature of about 95 degrees, the drink is collected in a glass container.

4. Automatic espresso machine. Such a coffee maker contains millstones that grind grains. After grinding the coffee, the grains are compacted into the filter. The drink is formed by passing boiling water under pressure through the filter. Ready coffee flows through the tube from the machine into the cup. The advantage of the device is in the freshness of the drink, a special aroma, ease of use, because it is enough to pour grains, pour water, and the drink will be ready. The downside is the high cost of the machine and expensive repairs in case it fails.

5. Carob coffee maker. In this machine, ground coffee is placed in a cone-shaped container, hence the name of the machine. The powder is tamped into a horn, pour water into a container. The high-pressure steam generated when boiling water passes through ground coffee, and the finished drink is poured into a cup. Coffee brewed using a carob machine is called espresso and is loved for its delicate lush foam. In addition to espresso, you can prepare other types of drink: latte, cappuccino, lungo, etc.

6. Pod coffee maker. The machine is able to prepare coffee from a tablet — a compressed powder weighing 7 grams. The advantage of the device is that you do not need to worry about grinding the beans, there is no noise, the need to fill and tamp the powder into the filter, as is the case with a conventional carob coffee maker. The whole process is maximally automated. Minus — you can not adjust the strength and saturation of the drink, since they are already determined by the manufacturer of the pod, and it is difficult to call the drink from the tablet itself exquisite. Therefore, all pod coffee makers are not only pod, but also carob, that is, in addition to tablets, they can also brew regular ground coffee.

7. Capsule coffee maker. The machine has a special compartment for placing a special capsule — a sealed object with ground coffee inside. During the preparation of the drink, the needle pierces the shell, forming an inlet for water and steam. The powder is heated and mixed with water, resulting in a drink. The advantage of this technique is in the price and cheap repair, and the disadvantage is that coffee in capsules is not as tasty as freshly ground coffee, although its aroma and taste remain in the capsule for a very long time — up to 24 months, so that only real gourmets feel the difference. .

With modern automated machines, the process of making coffee has reached the maximum simplicity. It is only important to carefully read the instructions for the technique or watch a video on how to brew coffee in a coffee machine, and then the procedure will bring only pleasure. Today, with the help of a coffee maker, you can brew up to three dozen different types of coffee drinks, you just need to set the appropriate programme and adjustments in the machine. This is probably why the choice of this very device should be approached as scrupulously as you used to approach the process of making coffee by hand in order to continue drinking the most delicious and aromatic drink in the world.
