Pre-Infusion - Profitec Ride Bedienungsanleitung

10.3.4 Pre-infusion

Pre-infusion ensures that the ground coffee in the portafilter is completely
moistened once before extraction is carried out at high pressure.
How pre-infusion works
At the start of the espresso extraction process, the pump actively builds
the pressure up for a predefined period of time. Before the pump pressure
has reached 9 bar, the pump interrupts the activity for another predefined
period of time. During this passive phase, the hot water completely soaks the
ground coffee. After soaking is complete, the extraction is started at 9 bar.
Example
Active pre-infusion = 4 seconds, passive pre-infusion = 5 seconds:
Pump activity starts for 4 seconds after the start of espresso extraction.
After these 4 seconds, the pump activity is interrupted for 5 seconds in order
to moisten the ground coffee. After these 5 seconds have elapsed, the pump
starts up again and the espresso extraction is started at 9 bar.
