General knowledge of espresso machine for making espresso

In 1901, Italian Milan engineer Luigi Bezzera invented the espresso machine. Italian coffee machine is a machine that uses high temperature and high pressure to make coffee quickly.

According to the type of boiler, Italian coffee machine is divided into single boiler heat exchange type, double boiler type and multi-boiler type; according to the mode of operation, it can be roughly divided into: manual, automatic, semi-automatic, fully automatic and so on. Most of the professional coffee shops use automatic and semi-automatic coffee machines, so, as professional baristas, we mainly learn how to use these two kinds of coffee machines. The automatic coffee machine can set the flow rate and time of brewing coffee water through its electric control board, and the more advanced automatic coffee machine can also adjust water pressure, boiler pressure, water temperature and so on. Compared with the automatic coffee machine, the semi-automatic coffee machine needs the barista to control the flow and time of the water used to make coffee, and the World barista Competition (WBC) also requires the barista to operate to control the flow and time of the water used to make coffee, so in the future study, there is no special description of the coffee machine, all refer to the Italian semi-automatic coffee machine.
