Abstract: A device for heating an amount of liquid in a container using steam, comprising a steam conduit coaxially arranged in a tubular element which axially extends substantially from the inlet end to the outlet end of the steam conduit from which it is radially spaced thereby forming a first axially-extending annular air gap. Said tubular element is coaxially arranged in a sleeve thereby forming a second axially-extending air gap, said first air gap and said second air gap being closed at both respective axial ends on said tubular element. The steam conduit is made of a polymeric material having a low heat transfer coefficient, the tubular element is made of a metal material and said sleeve is also made of a polymeric material having a low heat transfer coefficient.

Abstract: A wand for dispensing vapor for heating and/or frothing a quantity of milk by vapor being introduced into a container in which the milk is located. The wand is provided with a first end, in the region of which it receives the vapor, and a second end, through which the vapor is dispensed. The second end can be positioned inside and outside the container by means of angular movements of the wand about an articulation to which the first end is connected. The articulation is mounted on a portion of a machine for preparing drinks. The wand further comprises a thermoelectrical sensor for detecting the temperature reached by the milk in the container. The sensor can transmit an electrical signal relating to the detected temperature outside the wand.
