A milk extracting system and computer-implemented method of adjusting the vacuum pressures applied respectively at different teat cups for milking the teats of an animal during a milk extraction procedure, where a teat-specific milk flow value is determined for each individual teat during the milk extraction, based on measurements received from respective milk flow meters, each determined teat specific milk flow value is compared with a first threshold limit, and when a determination is made that all of the teat specific milk flow values exceed the first threshold limit the vacuum pressure at each teat cup is adjusted to a high flow vacuum pressure level.

Disclosed herein is a method of milking a cow using a milking cup of the type including a shell and a flexible liner, said liner including a hollow bore for receiving an animal's teat at a top end thereof, and for being connected to a vacuum source at the lower end thereof; the liner and shell being disposed relative to one another to create a pulsation volume between them in which fluid pressure can be controlled in order to control a pressure differential across the liner between its bore and the pulsation volume to thereby control movement of the liner and the application of air pressure to the animal's teat, the method including: Applying a vacuum to the lower end of the liner; Modulating the pressure in the pulsation volume according to a pulsation cycle to cause a milking operation on a teat of an animal that is inserted into the top end of the bore; said modulation including an on phase in which the vacuum applied to the liner bore is less than a vacuum applied to the pulsation volume to thereby enable milk flow from the teat, and an off phase in which the pulsation volume is at an increased pressure relative to the on phase to close the liner bore to thereby stop milk flow from the teat, said modulation including applying positive pressure to the pulsation volume to apply compressive load to the teat wherein the pulsation cycle has a duration of less than 1 second.

The present invention relates to preparing dairy animal teats for being milked, and more particularly to teat preparation, rinsing, and milking that all take place in a milking machine teat cup liner. Such a method includes: applying a teat sanitizer to the teat; injecting air into the liner to force the teat sanitizer toward a waste milk line connected to the liner; pulsating the liner at a first pulsation rate; drawing a rinsing milk from the teat; directing the teat sanitizer, the air, and the rinsing fluid to the waste milk line; pulsating the liner at a second pulsation rate to draw additional milk from the teat; and directing the additional milk to a good milk line.

A method and system for enhancing expression of milk from breast alveoli includes providing a pump that delivers a pulsed vacuum. The pulsed vacuum may be delivered by a vacuum pump employing a rigid piston that operates as a multi-stroke accumulator pump. In an embodiment, a piston head of the rigid piston undergoes a non-linear motion relative to a sidewall of a cylinder of the pump, resulting in an oscillatory impulse on the interior of the vacuum chamber in the cylinder. The vacuum pulse frequency of the pump is applied over a cyclical vacuum frequency that would otherwise be applied had the piston head only moved up and down while maintaining a perpendicular relationship to the sidewall of the cylinder.

A milking system equipped with teat cups each connected to a respective milk evacuation tube, a vacuum pump, a milk tank, vacuum regulators configured to control a vacuum pressure level prevailing in the teat cup, vacuum pressure sensors each configured to measure vacuum pressure level prevailing under one of the teats, an animal identification sensor, a database, a processing device configured to: determine animal ID, extract data of each respective teat from the database, determine a teat specific vacuum pressure level at each teat, and generate a command to each vacuum regulator, to set the teat specific vacuum pressure level at each teat cup.

A three-dimensional camera of an automatic milking system records image data representing an outer surface of a teat of a dairy animal in three dimensions. Based on the image data, a processing unit performs a geometric analysis and calculates at least one size measure of the teat. A user interface presents output data reflecting the size-related classification of the teat.

The present disclosure provides a method of milking a mammal which includes, applying a vacuum to the lower end of a milking cup liner; and modulating the pressure in the pulsation volume to cause a milking operation on a teat of an animal that is inserted into the top end of the bore. The modulation includes an on phase in which the vacuum applied to the liner bore is less than a vacuum applied to the pulsation volume to thereby enable milk flow from the teat, and an off phase in which the pulsation volume is at an increased pressure relative to the on phase to close the liner bore to thereby stop milk flow from the teat. The modulation includes applying positive pressure to the pulsation volume to apply compressive load to the teat.

The invention relates to a device for stimulating an udder during milking, made up of a housing with a first connection (350, 351) and a second connection (352, 353), which housing can be grasped by a hand. The first connection connects the housing to a pulsator and the second connection connects the housing to a teat cup. A throttle valve (305, 306) is interposed between the first connection and the second connection. A control device (309) is housed in the housing and is adapted to bring the throttle valve, after a defined duration, from a partially open to an open position.

A mechanical manifold valve for robotic milking that is designed to operate at varying pressures, and which is operated automatically according to the pressure in at least one of the teat cups, such that the pressure in that teat cup influences the operation of the manifold valve, thereby controlling the pressure in at least one additional teat cup.
