Abstract
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.
