A milking device has milking means, a controller, 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 cleaning the milk filter with cleaning fluid. The milk filter comprises a housing which surrounds a filter volume and has a milk inlet and a milk outlet, and a circumferential filter body. The filter body comprises filter holes and divides the filter volume into an inner filter volume and an outer filter volume. The milk filter is configured to be flushed during use. The cleaning device is configured to clean the milk filter. The filter holes are grouped into a first group and a second group. The diameter of the holes in the first group is greater than that of the second group.

A milking system includes a milking device, and a milk storage system having: a temporary milk storage vessel for temporarily storing milk from a plurality of milking operations, a milk pipe from the milking device to the temporary milk storage vessel, a milk tank for storing the milk from the temporary milk storage vessel, a control unit, a main milk pipe from the temporary milk storage vessel to the milk tank, a pressurized liquid supply which is controllable by the control unit and is provided and configured to supply a pressurized liquid, other than milk, to the milk storage system, a first and a second discharge provided on the main milk pipe, a selection device which is controllable by the control unit and is on the main milk pipe towards the first discharge or the second discharge, wherein the control unit is configured to perform a milk transferring action for transferring milk in the main milk pipe into the milk tank with the aid of the pressurized liquid, wherein the liquid transferring action includes bringing the pressurized liquid supply and the first discharge into liquid connection with the main milk pipe, and breaking a liquid connection of the main milk pipe with the second discharge, allowing an amount of pressurized liquid to flow under pressure from the pressurized liquid supply into the main milk pipe, and breaking the liquid connection between the main milk pipe and the first discharge. Transferring the milk in this way means that it is subjected to less mechanical load and mixed with less air, which benefits the quality. The invention also provides a temporary milk storage vessel and method of this type.

A milk tank system includes a first holder configured for intermediate storage of milk from several milkings of a milking device, and not being a milk glass; a second holder for storage of milk from the first holder; a transport device for transporting milk including a milk line from the first holder to the second holder, via which milk line the second holder may be brought into fluidic connection with the first holder, and a shut-off for shutting off the fluidic connection, in particular from the first holder to the milk line, wherein the transport device has a first operating state which is configured for collecting milk in the first holder, and a second operating state which is configured for transferring the milk from the first holder to the second holder, wherein the milk tank system further includes a control system for switching the transport device from the first to the second operating state when the milk in the first holder reaches a switching milk level which changes over time. Because the pumping of the milk from the intermediate milk storage vessel does not always begin at the same or comparable maximum milk level, but preferably at an ever increasing level, potentially caking milk residue is always rinsed away on a subsequent filling.
