What is a variable pressure coffee machine? What are the advantages of variable pressure extraction? How important is stress to the espresso machine

Variable Pressure, which means variable stress, is a groundbreaking concept in the field of espresso. Through the pressure control valve, during the whole extraction process of espresso, the pressure can be changed at will and controlled by the operator.

At the brewing head, the new manual paddle switch (Paddle) is used to change the temperature measurement point to the outlet, and a pressure control function is added, so that the pressure of coffee extraction can be adjusted freely between 3bar~9bar, so the following characteristics are produced:

-pressurized prepreg can be carried out and the prepreg time can be controlled.

-the cooking pressure can be adjusted at will, but the temperature remains stable.

-take advantage of the rise and fall of pressure to show different flavors of espresso.

With the change of pressure, the amount of water output per unit time is also different.

It is very interesting to use pressure control valve to extract espresso! Especially in the later stage of extraction, when the pressure is reduced, the sweetness and cleanliness of the whole espresso flavor are very good, or the whole use of low pressure extraction of about 3bar, about 50 to 60 seconds, can get a cup of light concentration similar to the flavor of single coffee.

During the trial, the pressure measuring handle is used to examine the current pressure.

Using low pressure, about 50 to 60 seconds, you can extract coffee with similar single flavor.
