Abstract

The present invention relates to a method for automatic separation of foremilk and/or milk not suitable for consumption from the milk line system of a milking plant and an apparatus for carrying out said method. A separating device (44) is arranged at the ends of a milk line (52) and a test milk line (56), said milk lines being parallel. The separating device is designed with a damper means (48) attached to a cup (46). When milk is fed through the outlet (16), the cup (46) is filled up and its weight pivots the separating device from a first position, in which the inlet to a milk line (52) is closed by means of the damper mean, to a second position, in which the milk in cup is poured into a test milk line (56) and the damper means is lifted off the inlet (50|) to the milk line (52).
