MILKING SYSTEM, METHOD OF CLEANING A MILKING SYSTEM AND MONITORING CLEANING OF A MILKING SYSTEM.

摘要

The present invention relates generally to milking systems and cleaning of milking systems. Especially it concerns the creation of slugs of cleaning liquid in milking systems. The milking system comprises a milk conduit (3), a liquid sensor (4) for detecting the presence of liquid in the milk conduit (3), a vacuum source (7) for applying a suction pressure to the milk conduit and cleaning equipment (12, 13) including means for supplying cleaning liquid into the milk conduit and an air injector (16) arranged to supply air into the milk conduit, said system being adapted to supply cleaning liquid into the milk conduit, apply a suction pressure to the cleaning liquid and supply air so that a liquid slug is created that flushes the milk conduit. The liquid sensor (4) is adapted to sense the presence of cleaning liquid supplied to the milk conduit, and the system is adapted to supply said air based on the detection of the presence of cleaning liquid. The sensing of the sensor (4) is also used for evaluating performance of cleaning operations.
