Milk samples are extracted automatically, the milk yield being held in a collector vessel under vacuum, mixed with air when milking is over, after which part of it is fed to a sampling vessel. The milk is delivered from the latter vessel (20) to an analysing unit (27) for immediate analysis. The milk remaining in the collector vessel (1) is only extracted after analysis is complete, and is fed either to a pipe (16) for usable milk, or to one (17) for non-usable milk, dependent on the result. The first jets of milk when milking starts can be extracted via the pipe for non-usable milk. Before storing milk in the sampling vessel, milk can be directed via the latter into the pipe for non-usable milk, until the preceding sample is displaced. |
