Patent ID: 10292526

Abstract:
A professional coffee machine includes a supporting frame; a boiler; a preheater to prepare a coffee infusion having a first heat exchanger with the boiler to heat the supply water crossing the first exchanger to a first temperature T1 close or substantially equal to a second temperature T2 corresponding to the optimal temperature for a coffee infusion; a dispensing unit of the coffee infusion having a thermo-controlled heating element that brings the water released from the preheater to the second temperature T2 if T1 is lower than T2; a thermal insulator that mechanically constrains the dispensing unit to the frame; a heater for preparing a tea infusion or the like having a second heat exchanger with the boiler to heat the supply water crossing the second heat exchanger up to a third temperature T3 corresponding to the optimal temperature for preparing a tea infusion or the like.
