  • the milk pump 6 removes milk from the end unit 4.
  • the output of the milk pump is connected to a non-return valve 7 which only allows flow out of the milk pump and not in the reverse direction.
  • the outlet of the non-return valve 7 is connected via two lines to respective control valves 8 and 9.
  • a first line is controlled by the control valve 8.
  • the valve 8 may be opened or closed.

  • From the teat cups the cleaning liquid passes through the valves 2a - 2d, through the milk meters 3a - 3d and into the end unit 4.
  • the cleaning fluid is pumped by the milk pump 6 from the end unit. Because the control valve 9 is open and the control valve 8 is closed the cleaning liquid passes only through the valve 9. From the valve 9 the cleaning liquid passes back via a connecting line to the source of cleaning liquid 24 where the used cleaning liquid is disposed of.

  • Rinsing may be controlled to take place after each cow has been milked. After a cleaning of the milk unit a rinsing takes place in order to remove traces of the cleaning liquid. In addition, rinsing may take place whenever milking of a cow has not taken place for a predetermined time period.
