Technologies That Changed The Coffee Machine

Coffee Maker Machine

 

The espresso machine is used to prepare coffee drinks based on espresso (cappuccino, latte macchiato, infusions). The main functions of the coffee machines like the Delonghi Ecam 23.420 (see the Delonghi Ecam 23.420 review here) are as follows:

  • Water supply at a temperature of 88° to 96° C, ideal for extracting the coffee mixture
  • Water supply at a pressure of 9 bar, which guarantees the triggering of the aromas in the cup.
  • Steam generation for heating and foaming milk for cappuccinos.

Here’s a quick guide to the key technologies to help you decide on a model coffee maker that best suits your needs.

TRADITIONAL COFFEE MACHINES

Traditional machines are usually connected to a coffee grinder, which allows you to use freshly ground coffee. Conventional machines can have single or multiple groups and are divided into semi-automatic or volumetric machines. In the first case, there is a manual button for each group, in the second case a preset dosage that automatically adjusts the amount of coffee.

LEVER CAFÉ MACHINES

In lever machines, the water pressure is generated by a piston connected to a lever. To allow water to be released, the lever must be pulled down into the group with the coffee powder after inserting the filter holder. Consequently, there is no mechanical pump in these machines. These machines require a higher level of user competence and are also characterized by lower productivity compared to conventional machines with several groups.

SUPER AUTOMATIC COFFEE MACHINES

The super vending machines are characterized by the fact that they handle the grinding, pre-infusion, coffee extraction and preparation of the drink fully automatically. The desired drink can be selected via a digital display and a keypad. Durability and reliability depend on the care or quality of the construction.

COFFEE MACHINES WITH PADS (CAPSULE)

Pad or capsule machines are usually small machines that are suitable for use in the home or office. The coffee capsule or coffee pod is inserted into the machine and the extraction is switched on. At the same time, the drink is dispensed.
