Abstract:
A milking device for milking a dairy animal is provided with milking mechanism, a control system, a milk pipeline for transporting the milk from the milking mechanism to a milk tank, a milk filter and a cleaning device. The cleaning device includes at least one cleaning fluid holder, a heating device for heating cleaning fluid in the cleaning fluid holder, an additive storage holder for additive, an additive adding device for controlled addition of the additive to cleaning fluid, and a valve system for regulating flows of cleaning fluid and additive through the milking device. The cleaning device is configured for carrying out a cleaning cycle of the milking device with a prerinse with cold or tepid water, a hot rinse with heated water and an acidic or basic additive, a postrinse, and at least between the hot rinse and the postrinse, a counterflow cleaning step by passing cleaning fluid in counterflow through the milk filter. Thus, a milking device is provided that can be cleaned automatically as a whole including the milk filter. In particular, because the counterflow cleansing takes place after the hot rinse step, there is better removal of dirt and milk residues that are softened thereby, in particular from the milk filter.
Abstract:
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.
Abstract:
A milking system includes several milking devices, each having a milk-carrying part, a temporary milk storage vessel, a milk pipe system, a milk storage tank, and a main milk pipe, which connects the temporary milk storage vessel to the milk storage tank. The milking system includes a first cleaning device having at least one first cleaning liquid supply and at least a pump, which cleaning device is configured to clean at least the milk-carrying part of at least one milking device and a part of the milk pipe system which connects the milk-carrying part to the temporary milk storage vessel, by transferring cleaning liquid from the cleaning liquid supply through at least the milk-carrying part of the at least one milking device and through said part of the milk pipe system to the temporary milk storage vessel by pumping. The temporary milk storage vessel includes a main pump for transferring liquid from the temporary milk storage vessel through the main milk pipe in the direction of the milk storage tank. The milking system includes a second, additional cleaning device with at least one second, additional cleaning liquid supply, which second cleaning device is configured to supply additional cleaning liquid from the second cleaning liquid supply in a direction of flow from the temporary milk storage vessel towards the main milk pipe. The second cleaning liquid supply is situated downstream of at least each of the milking devices, viewed in said direction of flow.
Abstract:
A safety valve (10) for a cleaning device for a milking installation for milking milk-providing animals comprises a first block valve (11) having an intake (110), a second block valve (12) having an exhaust (120), a bleed valve (13) having a bleed outlet (130), a piston (25), and a drive unit (28) wherein the safety valve (10) is configured so as to be adjustable to and fro between a blocking position in which the first block valve (11) and the second block valve (12), in order to block the intake (110) and the exhaust (120), are closed and the bleed valve (13), in order to connect the bleed outlet (130) to a connection (14′) is opened, and a throughput position in which the first block valve (11) and the second block valve (12), in order to connect the intake (110) by way of the connection (14′) to the exhaust (120), are opened and the bleed valve (13), in order to block the bleed outlet (120), is closed. The safety valve (10) is configured as a directional valve, the piston (25) being a hollow piston (250).

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.
Abstract:
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.

Abstract:
A milking system includes a milking member for extracting milk from an animal, a transport line, a milk tank, a milk filter unit for filtering the milk with a first filter device and a second filter device, each including a filter container and a filter element, and a valve arrangement to convey milk through the devices, where the valve arrangement communicates with a control unit. The milking system further includes an indication device generating an indication to a user when any one of the filter elements needs to be replaced, which filter of the first and second filter device needs to be replaced, and when the filter element indicated to need to be replaced is accessible for replacement. A method for operating and cleaning the milking system is also provided.
Abstract:
In a milking cluster of teat cups, each teat cup has a port in the form of a nozzle disposed in the head portion of the flexible liner of the teat cup. The milking cluster includes a distributor having a fluid inlet and outlets connected to the nozzles of the cups. The distributor inlet is connected to a delivery line for supplying sanitising treatment fluid, which is utilised to treat the teats and teat cups in a cleansing cycle following the milking cycle, by a second valve operable to maintain the delivery line primed with treatment fluid preparatory to initiation of the cleansing cycle. A safety valve is disposed at the distributor inlet, the safety valve being operable during a milking cycle to open a drain port through which treatment fluid may flow to waste.
Abstract:
A method is provided for eliminating the risk of leakage from a first one to a second one of two fluid systems in an apparatus for handling a fluid for human consumption, with a shut-off device including a cavity and a respective valve element connecting the cavity to each of the two fluid systems, each valve means being capable of preventing any fluid communication from the cavity to the respective fluid system. When the valve element prevents any fluid communication from the cavity to the fluid systems, a fluid is supplied to the cavity and a pressure is provided in the cavity which is higher than one or each of the respective pressures in the two fluid systems, thereby eliminating the risk of leakage from a first one to a second one of two fluid systems in case of failure of the valve element.
