The distinction between Steam Coffee Machine and Pop Coffee Machine
Due to the difference in structure and principle, the Italian coffee machine is roughly divided into two types: steam type and help type (aluminum casting pressure cavity), which can be easily distinguished from the outside. There is a knob on the top of the steam coffee machine, but the help coffee machine does not.
The steam pressure of the steam coffee machine is only about 5BAR, while the Pangpu coffee machine can produce a steam pressure of 15 to 19 BAR. The pressure will affect the quality of the coffee. The higher the pressure, the more ingredients can be extracted, making the coffee more mellow. However, the pressure is also limited, the current professional models can do 15 to 19BAR.
