ABSTRACT:
A milking system having a substantially stable continuous vacuum level through a milk claw and milk hose. The milking system includes a milking apparatus for connection with an animal's teats to apply a controlled vacuum thereto to remove milk therefrom at various milk flow rates. A milk claw is operatively connected to the milking apparatus to receive and pass the milk. The milk claw includes an outlet having side walls and a predetermined cross-sectional area selected to be in the range of a minimum cross-sectional area for maintaining, at a all milk flow rates, a substantially uniform laminar flow of milk therethrough and for concurrently providing a stable continuous vacuum in a vacuum channel between the laminar flow of milk and the interior side walls of the outlet and a maximum cross-sectional area equal to about 1.5 times the minimum cross-sectional area. A milk transportation conduit includes a milk hose formed of a semi-flexible material and any intermediate control devices operatively coupled between the inlet and outlet of the milk claw to transport the milk from the milk claw to a milk line. All intermediate control devices have a predetermined cross-sectional area substantially equal to the predetermined cross-sectional of the outlet of the milk claw.
