Abstract: 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.

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 milking device is provided with milking device, a control unit, a milk line for transporting the milk from the milking device 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 surrounding 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 holes, and divides the filter volume into a central inner filter volume and an outer filter volume surrounding the latter. The milk filter is configured to be flushed, in use, with the milk to be filtered from the milk inlet to the milk outlet. The cleaning device is configured to clean the milk filter by passing cleaning liquid through the milk filter in a countercurrent direction in consecutive pulses, in such a way that, in each pulse, during a first pulse stage more cleaning liquid is supplied than is discharged, and subsequently, during a second pulse stage, at least as much cleaning liquid flows from the filter volume as is supplied. As a result thereof, an amount of cleaning liquid always collects in the filter volume up to a liquid level, which surrounds at least some of the plurality of holes. The next pulse makes cleaning liquid collide with the liquid level, which improves the cleaning of the filter.
