A system that attached to mechanized milking equipment allows its automation that solves the subclinical mastitis by “differentiating” among each individual mammary quarter the time when teat cups must be removed after the milk is over, in an asynchronous and independent manner from other teat cups. Minimize the negative consequences of over-milking as a results of not removing teat cups on time after the milk flow has stopped; reduces economic, financial and productivity problems arisen as a result of subclinical mastitis mainly caused by over-milking; thus improving the product quality and amount. Mastitis produces somatic cells in milk, the greater the amount of these cells the lower the price received by the producer. Damage to the mammary gland may be permanent resulting in the loss of the gland and may be contagious.The system includes teat cups, tubes, collector, discrete flow sensor, vacuum sensor, command control, software comprising as a part thereof the mammary quarters with physiological and anatomical characteristics thereof.

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.
