Abstract: A machine for dispensing a hot infusion beverage having at least one main boiler provided with main heating elements for heating an infusion liquid is provided. An electronic control unit operatively connected to the main heating elements is programmed to control the main heating elements so as to cause overheating of the infusion liquid at a temperature higher than a desired target temperature, for a predetermined time interval.

Abstract: A machine for dispensing an infusion beverage is provided. The machine has a pump group, a dispensing group, a flow adjustment solenoid valve, and an electronic control unit. The electronic control unit is programmed to execute a low-flow phase in which the pump group is activated and, substantially simultaneously, the flow adjustment solenoid valve is commanded to switch into an open configuration. After a predetermined time interval, the flow adjustment solenoid valve is commanded to pass into an intermediate configuration until the end of the low-flow phase, while the pump group remains active.

Abstract: A machine for dispensing an infusion beverage having a pump group, a dispensing group and a flow adjustment solenoid valve is provided. The flow adjustment solenoid valve, fluidly interposed between the pump group and the dispensing group, is suitable for controlling a flow rate of an infusion fluid by use of a shutter, and is configurable in a closing configuration, in which the pump group is inactive and the shutter occludes passage of the infusion fluid, and in a complete opening configuration, in which the pump group is operational and the shutter is fully lifted. Flow adjustment elements regulate the passage of the infusion fluid. Between the closing configuration and the complete opening configuration, the flow adjustment solenoid valve is arranged in an intermediate opening configuration, in which the pump group is operational and the flow adjustment elements allow partial raising of the shutter.
