Thanks to the Multiboiler Realtime Stability system it is possible to set – for each single distribution group – the temperature of the coffee boilers, in accordance with the blend and/or the single-origin coffee used. The system can guarantee a complete independence between the distribution of coffee and steam, ensuring that the two actions do not affect each other, thus compromising a good outcome. The electronic control unit is equipped with a PID temperature management system, which independently regulates the coffee boilers and the heating of the individual groups. Pre-infusion is the first phase in the extraction of coffee: the powder is wet and prepared for the following optimal extraction. Furthermore, pre-infusion allows to make the powder uniform in order to avoid the formation of preferential routes.
