This invention relates to a device and a method for sampling of milk. The device includes a collecting member (15, 15′) arranged to receive milk samples from a milk line (1), which is arranged to transport milk from one animal (3) at a time, and a passage (8a, 12″, 13) arranged to allow a milk flow from the milk line (1) to the collecting member (15, 15′). The device comprises flow means (11, 19) arranged to provide a milk flow, from the animal (3), through at least a part of the passage (8a, 12″, 13) at least a time period before a milk sample is to be taken in order to rinse at least the part of the passage (8a, 12″, 13) from milk residues from a previously milked animal.

A diaphragm valve for shutting off the milk flow through the claws of a vacuum-driven milking machine, the valve in a preferred embodiment having a lever (5) connected to the outside of the milk flow with a link (6) on the diaphragm (4), thus avoiding any easily leaking sleeves. The lever (5) can be swung by hand to a position that holds the diaphragm off its seat allowing milk to flow. In the self-closing embodiment, the lever is in this case against the bias of the spring (7) and remains at the position when the suction force acting on the diaphragm (4) and connecting rod (6) is sufficient to overcome the bias of the spring (7). In this open position, this is the case where milk flows normally through the valve. When the milking cup is removed from the animal's teat, only air flows through the valve, thereby reducing the suction force on the linkage (6) and allowing the spring (7) to swing the lever away from its valve-opening position to a loose When the diaphragm is in the open position, air suction will pull the diaphragm, sealing it against the valve seat, cutting off the flow of potentially contaminated air through the system. The principles of the invention can also be implemented on a rotating knob (21) which is attached to the diaphragm (4) and interacts with an inclined groove (23) and a spring (24) biasing the knob to Advance to a position where the diaphragm is released when flow is insufficient. This system is especially useful on sheep or goat dairy farms where milking cup assemblies are frequently installed and removed.

The invention discloses a method for quickly dissolving powdered milk. According to the method, firstly, water is sprayed into a water guide seat by virtue of a water discharge mechanism to form eddying current which rotatably flows clockwise or counterclockwise in the water guide seat; secondly, powdered milk is uniformly fed into the water guide seat by virtue of a powdered milk discharge mechanism, and the powdered milk falls down on the edge of the eddying current; thirdly, the powdered milk and the eddying current are mixed completely to form milk, and the milk flows out from a flow restricting port of the water guide seat, meanwhile, the powdered milk which is not completely dissolved is pressurized and dissolved by the flow restricting port; and finally, when the milk dissolving process is completed, the powdered milk discharge mechanism is firstly turned off for stopping feeding the powdered milk, and then the water discharge mechanism is turned off for stopping spraying water. In the method, after the eddying current is formed, the powdered milk is added, so that the powdered milk can be sufficiently mixed with the eddying current, milk residue is prevented, and the milk quality is guaranteed.

Adaptation to animal size and position in the stall is provided with a coarse adjustment of the hose support tree. Finer adjustment for optimizing milk flow and preserving animal health is accomplished by providing a selection of hose positions that also hold the hose in position. Further adaptations include attachment to milking stalls of differing configurations including rotary milking parlors.

The present invention refers to an apparatus (11) and a method for milk filtration and filter regeneration. The apparatus comprises a filter vessel (13); a loose filter material (37) housed within the vessel for filtering out contaminants in the milk; and a grid (31) arranged in front of the milk flow outlet to prevent the loose filter material from leaving the vessel. The vessel includes inner walls (15, 17); a milk inlet (21); a milk outlet (23); a cleaning fluid inlet (23) arranged substantially vertically at the lowermost portion of the vessel, through which a cleaning fluid jet can be injected, and a cleaning fluid outlet (21) arranged at the upper portion of the vessel. The lower portions (17) of the inner walls of the vessel form an angle (alpha) with respect to the horizontal plane, the angle being larger than the angle of repose for the filter material in the cleaning fluid. Thus, the filter material, which is flowed vertically upwards (45) by the cleaning fluid jet, moves substantially radially outwards (45) with respect to the jet to descend downwards (47) and slide back (47) towards the jet by aid of the angled inner wall portions.
