Method and apparatus for cleaning a milk line system

A method of determining the extent to which a milk line system is rinsed by a fluid containing hydrogen peroxide comprising maintaining said hydrogen peroxide containing fluid at a selected temperature and measuring it in one or more places in the milk line system to determine the electric conductivity of said hydrogen peroxide containing fluid as it is flowing therethrough, and determining the purity of said hydrogen peroxide containing fluid at said one or more places in the milk line system based on the electric conductivity of said hydrogen peroxide containing fluid as so measured.

A method of cleaning and rinsing a milk line system which in series comprises a rinsing fluid line, a plurality of separate rinsing fluid supply lines receiving a rinsing liquid from said rinsing fluid line, a rinsing jetter in each of said rinsing fluid supply lines, a plurality of teat cups, each of which is disposed to receive said rinsing liquid from a corresponding rinsing jetter, a discharge line from each said teat cup, a receptacle receiving liquid flowing from said teat cups through said discharge lines, and a liquid passage connection between said receptacle and said rinsing fluid line that completes the circuit for the flow of liquid in said milk line system, the method comprising equalizing the flow of said liquid from said rinsing jetters through each of said teat cups, circulating cleaning fluid in said circuit to remove milk residues from milk line system, flushing water through said milk line system to remove cleaning fluid residues from said milk line system while measuring the flows of ionic electrical current between electrodes provided in said discharge lines to determine the completeness of the removal of said cleaning fluid residues therefrom.

A method of cleaning elements for cleaning the teats and udders of milk producing animals that are milked by automatic milking systems wherein the animals are milked by robotic mechanisms which automatically apply cleaning elements to clean the animals' teats and udders and remove said cleaning elements thereafter to be automatically cleaned, the method comprising conducting water through a conduit, selectively adding a disinfectant to said water while said water is flowing through said conduit, cleaning said cleaning element with the resulting mixture of cleaning water and disinfectant, measuring the electrical conductivity of said water before adding disinfectant thereto and transmitting measurements so obtained to a computer, and measuring the electrical conductivity of the mixture of the cleaning water and the added disinfectant and transmitting measurements so obtained to said computer.

A method of cleaning a dairy farm milk line system wherein the cleaning fluid used for cleaning said milk line system comprises hydrogen peroxide.

A method of cleaning a dairy farm milk line system by causing a cleaning fluid to flow therethrough, said cleaning fluid being composed of peracetic acid as an equilibrium product obtained by mixing hydrogen peroxide with a acetic acid.
