  • the flow regulator 100 is a constriction, suited to allow the passage from the portion 45 to the portion 46 of the correct water flow rate to be mixed with the sanitizer inside the portion 46.
  • flow regulators 100 suited to allow the passage of different water flow rates towards the portion 46 may be used to regulate the proportions of water and sanitizer flowing out from the outlet mouth 4. In this way, it is possible to use the operation of the unit 1 for washing the dispensing system containing beverages of various type and, therefore, with different sugar content.
  • the fluid line 16 comprises, furthermore, a pair of non-return valves 50, which are interposed along the conduit 42 and are arranged in series one to the other in a fluid manner.
  • each non-return valve 50 comprises, in turn:
  • Each shutter 51 is interposed, along the conduit 42, between the respective elastic element 53 and the inlet mouth 3.
  • non-return valves 50 are configured to allow the flow of water and sanitizer mixture from the inlet mouth 3 towards the end of the conduit 42 opposite to the inlet mouth 3, and to prevent the return flow of water in the opposite direction.
  • conduits 40, 42 and the portion 44 of the conduit 41 extend parallel to the axis A; the portion 45 of the conduit 41 extends parallel to the axis B.
  • valve means 5 essentially comprise ( Figure 4 and 5 ):
  • valve 55 is movable between:
  • the valve 56 is movable between:
  • valves 55, 56 are solenoid valves.
  • the control unit 12 is programmed to:
  • valve 55 in the open position, allows the water to flow from the inlet mouth 2 to the outlet mouth 4 along the fluid line 15, and the valve 56 in the closed position prevents the water from flowing along the conduit 41 of the fluid line 16 towards the inlet mouth 3.
  • valve 55 in the closed position prevents the water from flowing along the conduit 22, and the valve 56 in the open position allows the water to flow towards the inlet mouth 3 and along the fluid line 16.
  • the flow rate gauge 17 is suited to generate a signal associated with:
  • the flow rate gauge 17 is interposed in series and in a fluid manner between the conduit 42 of the fluid line 16 and the conduit 23 of the fluid line 15.
  • the flow rate gauge 17 detects the amount of water flowing from the conduit 22 towards the conduit 23 through the conduit 42.
  • the flow rate gauge 17 detects the amount of water and sanitizer mixture, which flows from the conduit 42 to the conduit 23.
  • the flow rate gauge 17 is, in the example shown, a mass flow sensor.
  • the assembly 11 comprises:
  • the pump 61 comprises:
  • the pump 61 is a peristaltic pump, so as to preserve the sterility of the sanitizer.
  • the control unit 12 is programmed to receive an input signal from the flow rate gauge 17.
