A device for rinsing milk pails automatically allows the use of a known rinser that rinse is suctioned into subject to partial vacuum and leaves again subject to atmospheric pressure. Prior to cleaning, a check valve is mounted over the milk-inlet connection and a cap over the air-suction connection to the upside-down milk-pail lid and the milk pail positioned on it with an annular spacer in between. The milk-inlet connection and the air-suction connection are connected to the rinser with hoses. During the initial suctioning stage, rinse is suctioned out of a rinsing tub through the teat cups, which are also connected up, and the pail simultaneously evacuated. When air is allowed into the rinser, part of the rinse flows back into the rinsing tube through the teat cups and the rest is sprayed into the milk pail, which is subject to partial vacuum, through the milk-inlet connection, the check valve, and a spray nozzle. During the next suctioning stage the rinse in the pail is suctioned out again through two channels and the pail is again evacuated. This process is repeated constantly during rinsing.
A device for automatically rinsing a milking pail, for use with a rinser that rinse is suctioned into subject to partial vacuum and that leaves again subject to atmospheric pressure and a milking pail having a lid provided with a milk-inlet connection having a portion projecting out of the inside surface of the pail lid and an air-suction connection that has a check valve, the device comprising:
In a milking system having teat cups and a rinser connected to the teat cups for suctioning rinse into and emptying rinse out of the teat cups immersed in a tub of rinse by alternately subjecting the teat cups to a partial vacuum and atmospheric pressure, the improvement comprising:
In a method of rinsing in a milking system wherein teat cups are immersed in a tub of rinse, a rinser is connected to the teat cups for suctioning rinse into the teat cups by subjecting the teat cups to a partial vacuum and emptying the rinse through the teat cups by subjecting the teat cups to atmospheric pressure, the improvement comprising rinsing a milk pail during the rinsing of the teat cups by inverting the milk pail to dispose the cover at the bottom thereof, connecting the milk inlet and air suction connections in the milk pail cover to the rinser, evacuating the contents of the milk pail during the suctioning of rinse through the teat cups by the partial vacuum and establishing a partial vacuum in the milk pail and providing a spray nozzle at the milk inlet inside the pail, whereby during the emptying step rinse is simultaneously suctioned into the milk pail through the spray nozzle as a result of the partial vacuum in the milk pail.
