Coffee machine features

The high popularity of coffee machines stimulates a high level of competition in this segment, forcing manufacturers to constantly improve their models due to innovations and expanding their capabilities. Functionality is one of the main criteria for choosing a coffee machine. Of course, it depends on the technical characteristics of the coffee machine and its type. Today the market offers traditional drip coffee machines, compression (carob) espresso coffee machines and steam coffee machines, each of which has its own features.

The list of basic functions of modern coffee machines.
Automatic decalcification.

The intensity of scale formation depends on the water hardness. It reduces the service life and the device performance. Automatic decalcification is designed to solve this problem.

This function removes the coffee oils and a scale on the walls and on the inner surface of the hoses with the help of the special cleaning tablets.

The screen of some models displays a message about the need for cleaning.

Cup warmer.

Many modern models are equipped with this function that is intended for pre-heating the cups or reheat of finished coffee.

The use of preheated cups enhances, according to experts, the taste and aroma of coffee. The cup temperature of 40 degrees is considered optimal. The cup warmer is usually placed on the top surface.

The implementation of this function in DeLonghi ECAM 25.462 is shown in the video at the end.


This attachment is intended for whipping the milk and cream. It’s divided into mechanical and automatic models. Of course, automatic cappuccinatore is much more convenient. Mechanical models are effective only for whole milk or cream.

Adding the foam in the coffee is performed automatically or manually depending on the model.

Pressurized steam passes through a Panarello Milk Frother and forms the foam into a glass with milk.


Expensive models support the user mode, providing setting the coffee strength, its temperature, etc. These values can be stored in the device memory.

Programmable timer is used for coffee making at the set time. But, all the ingredients must be pre-loaded into the device.

Adjustment of the coffee strength is performed by various methods. It depends on the water temperature, velocity of its passage through the coffee, from ratio between ground coffee and water, etc. Accordingly, companies use a particular technology in their models. For example, E-Plus system adjustments the coffee strength by changing the water pressure.

Water amount in cup can also be used to adjust the coffee strength.

Automatic dispenser.

Some premium models have automatic dosing. The device displays a list and amount of required ingredients for a selected recipe of coffee. This information is displayed on the screen.
