A safety valve arrangement and method, having an upstream block valve, a downstream block valve, and a pressure monitored galley between the upstream valve and the downstream valve.

A teat dip fluid manifold and methods for distributing teat dip fluids, and including redundant valve sets and pressure monitoring between valve pairs to determine valve condition.

Methods comprised to clean and/or lubricate fluid encompassing systems and systems' components comprising of a sequence of procedural steps. These systems' and components are susceptible to buildup of contamination and remnants from a chemical agent in this system, which can cause equipment failure if not properly maintained by using an effective method comprised to clean and/or lubricate this system.

This method ensures a chemical agent's physical and chemical and properties are not altered when applied to this system. This method directs a flow of a chemical agent onto the surfaces of this system's components.

After this system is cleaned and/or lubricated using this invention's method, this method's final step removes a chemical agent and/or contamination from this system to prevent consumer(s) from ingesting this chemical agent and/or contamination. This method also ensures no residue and no remnants from a chemical agent and/or contamination remains in this system, which helps prevent equipment failure, corrosion, and buildup within said system.

This method helps maintain and/or improve the functionality of this system, which helps prolong the life span of this system and said system's components.

A cleaning system for an automatic milking system includes a water supply arrangement alternatively serving first and second cleaning arrangements. The first cleaning arrangement is configured, in milking mode, to clean the teat cups of the automatic milking system and/or the teats of milking animals prior to being milked. The first cleaning arrangement includes at least one cleaning module, at least one feed line interconnecting the cleaning module with a tank, and a feed pump for feeding water from the tank to the cleaning module. The second cleaning arrangement is configured, in system cleaning mode, to clean the automatic milking system and includes a detergent supply system connected to the tank for supplying detergent to the tank, and a supply line interconnecting the tank with the automatic milking system allowing the cleaning liquid to be supplied to the automatic milking system.

The cleaning of milk transporting conduit structure involves introducing fluid and an amount of gas into the milk transporting conduit structure, which causes a slug of fluid to be formed in and forwarded through the milk transporting conduit structure. A sensor arrangement measures at least one parameter related to the slug, and repeatedly forwards updatings of the at least one measured parameter to the data processor. Based thereon, the data processor produces an indicator of at least one quality of the cleaning process. The indicator reflects a cross-sectional profile of the slug at at least one position in the milk transporting conduit structure.

Milking clusters for a miling installation have four teat cups, each teat cup having a cup housing and a teat cup liner with a top region and a suction region. A connection for a milk tube is arranged at the cup bottom or at the end of the suction region of the teat cup liner. A mouth portion of a sterile air pressure line is arranged in the top region of the teat cup liner, through which pressure line sterile air is introduced at a volumetric flow rate greater than a fluid aspiration volumetric flow rate at the milk tube, such that a sterile air blanket is established in the top region of the teat cup liner. The milking clusters with the cup liner and sterile air blanket prevent milked milk from being contaminated by contaminants and microorganisms from the shed air, extending storage life for untreated raw milk.

A arrangement for milking animals includes a milking station, a transport conduit, a main milk tank storing milk from the milking station, a connection conduit extending from the transport conduit to the main milk tank, a cleaning liquid arrangement, and a valve arrangement. From the milking station a connection pipe leads to the transport conduit at a connection point. The cleaning liquid arrangement is connected to the transport conduit via the valve arrangement. The valve arrangement is positionable in at least a first position and a second position. In the first position the transport conduit forms a loop such that two flow paths from the connection point to the connection conduit are provided by the transport conduit, and in the second position the loop is interrupted such that one flow path only from the connection point to the connection conduit is provided by the transport conduit.

An automatically cleanable milk filter includes a cylindrical housing with a longitudinal direction and with a cylindrical outer wall, a first end with a first liquid connection, and a second end with a second liquid connection, wherein, during use of the filter, the second end is situated above the first end. A concentric cylindrical filter plate containing a plurality of filter holes with a smallest diameter of between 60 and 100 um and a cylindrical core which is placed concentrically within the filter plate are accommodated in the housing. The filter plate divides the filter volume into a first volume part which is directly connected to the first liquid connection, and a second volume part which is directly connected to the second liquid connection. The second volume part includes a cylindrical part, as well as a top part which narrows at a transition to the second liquid connection. The cylindrical part, viewed in a direction towards the second liquid connection, extends at least a predetermined distance beyond the plurality of holes in the filter plate, and the first volume part, viewed in a direction towards the second liquid connection, does not extend beyond the filter plate. In this way, the stream of cleaning liquid, supplied from above, can develop beyond the top part to form a more turbulent stream parallel to the cylindrical part, and thus a more thorough cleaning of, in particular, the upper filter holes. In addition, a milking device including this milk filter is provided.

A system for cleaning a dairy animal milker unit and applying dip to a dairy animal, the system includes a main control, an air supply, a water supply, a backflush fluid supply, a dip supply, a stall control for receiving the air, water, backflush fluid and dip supplies, and a safety valve that is adjacent to a downstream portion of the milker unit to control backflush and dip fluids being fed to the milker unit.

A milking device is provided with milking means, a control unit, a milk line for transporting the milk from the milking means to a milk tank, a milk filter for filtering the milk passing through the milk line, and a cleaning device for the milk filter with cleaning liquid. The milk filter includes a housing which surrounds a filter volume and has a milk inlet and a milk outlet, and a filter component in the filter volume. The filter component includes a circumferential plate part with filter openings, and divides the filter volume into a central inner filter volume and an outer filter volume surrounding the latter. The filter component includes wire with a unilaterally tapering cross-sectional profile and a frame. The wire is provided in a spiral shape with a plurality of windings or in a series of individual parallel rings or rods.
