ABSTRACT:
An apparatus for taking out an average sample of milk proportional to the yield from the milking of a cow. The apparatus comprises a primary sampling system and a secondary sampling system. The primary sampling system has a chamber into which milk is sucked during the milking of the cow through a first tube terminating at a distance from a superimposed circular cylinder the bottom of which forms a substantially horizontal circular distributor surface which spreads the milk to form a film. A fraction of the film is caught between a first pair of knives, which are not integral with the distributor surface, and passed through a normally open valve into a collecting cup, while the major part of the milk leaves the chamber through a discharge tube in the bottom of the chamber. The secondary sampling system is adapted on completion of the milking to suck the milk from the collecting cup upwards into the chamber through a second tube extending from the bottom of the collecting cup and terminating at a distance from a superimposed second circular cylinder the bottom of which forms a second substantially horizontal circular distribution surface which spreads the milk to form a film. A fraction of that film is caught between a second pair of knives, which are not integral with the second distributor surface, and led down into a test cup, while the major part of the milk from the collecting cup leaves the chamber through the discharge tube in the bottom of the chamber.
