Definitions

  • the invention relates generally to a milking system arrangement for milking animals, such as cows. Especially, to an arrangement comprising a plurality of milking stations connected to a common milk line and comprising cleaning equipment for cleaning the milk line.
  • Modern milking systems comprise milking stations adapted to milk animals, such as cows, and transfer the extracted milk to a milk storage tank, while waiting for transport to a dairy plant.
  • the milk is a vulnerable food product and it is important to protect it from micro-organisms and prevent chemical reactions.
  • the equipment of a milking system therefore has to be cleaned regularly.
  • a way to clean the equipment is to empty the system from milk and supply a cleaning liquid, by means of a cleaning liquid supply line, to the milking system.
  • the cleaning liquid is then circulated through the system.
  • Such systems both handle vacuum and pressures, raising the requirements for sealing the system and preventing contamination of the milk.
  • the invention provides a method and an arrangement of a milking system that includes milking stations and a milk line, said milk line being arranged for transferring extracted milk to a storage tank.
  • the milking stations have means for transferring liquid, such as milk and cleaning liquid, to the milk line, and return lines for liquid are arranged for conveying liquid from the milk line to each milking station.
  • each milking station can be arranged to clean a section of the milk line.
  • the cleaning of the milk line can be divided among a plurality of milking stations.
  • the milking system arrangement in accordance with the present invention comprises a plurality of milking stations for extracting milk from animals, a milk line and a storage tank.
  • a first milking station of the plurality of milking stations in the arrangement comprises means for transferring milk to the storage tank via the milk line, said transferring means comprising an access conduit arranged to lead milk from the first milking station to a first portion of the milk line, and a second milking station of the plurality of milking stations comprises means for transferring milk to the storage tank via the milk line, said transferring means comprising an access conduit arranged to lead milk from the second milking station to a second portion of the milk line.
  • the milking system arrangement is characterised in that a first return conduit is arranged from the first portion of the milk line to the first milking station so that liquid can be circulated from the first milking station, through the access conduit of the first milking station, through the first portion of the milk line, and through the first return line back to the first milking station, and a second return conduit is arranged from the second portion of the milk line to the second milking station so that liquid can be circulated from the second milking station, through the access conduit of the second milking station, through the second portion of the milk line, and through the second return line back to the second milking station.
  • each milking station and respective milk line portion can be used to circulate a liquid and thereby counteract gathering of milk remains in the milk line.
  • each of the first and second milking stations is adapted to circulate cleaning liquid through their respective access conduit, milk line portion and return line. In this way the milking stations can cooperate in cleaning the milk line.
  • the first portion of the milk line is arranged next to the second portion of the milk line. In this way there is basically no portion of the milk line between the first and second portions, so that the whole milk line that passes the milking stations can be cleaned.
  • each of the first and second milking stations comprise means for providing a cleaning liquid, such as a water supply connection, means for dosing a detergent and means for heating the cleaning liquid.
  • each of the pumps includes a pump.
