Patent ID: 7690328

Claim:
A milk conveyer device for a milking arrangement having a milk storage reservoir; and at least one milking unit comprising: a milking attachment for attaching to an animal to be milked; and a main milk conduit, coupled to the milking attachment and the milk storage reservoir, for conveying milk from the milking attachment to the storage reservoir; the milk conveyer device comprising: an analysis element for analyzing at least one selected characteristic of an analysis milk sample generated from a milk analysis quantity; and at least one sample unit comprising: a sample element for extracting sample milk quantities from the milk of the main milk conduit; a sample reservoir coupled to the sample element for collecting the sample milk quantities to generate the milk analysis quantity; an analysis conduit, coupled to the sample reservoir and operable to be coupled to the analysis element, for conveying the milk analysis quantity from the sample reservoir to the analysis element; an outlet valve between the sample reservoir and the analysis conduit, the outlet valve being operable to be closed during collection of sample milk quantities and opened during conveying of the milk analysis quantity to the analysis element; and a conduit inlet gas valve coupled to the analysis conduit towards the outlet valve and operable to open when the outlet valve closes thereby providing a gas exerting a pressure on the milk analysis quantity in the analysis conduit; wherein at least part of the milk analysis quantity provides a cleaning effect of at least the analysis conduit thereby reducing residues of a previous milk analysis quantity conveyed to the analysis element through the analysis conduit, and wherein a pulsating open/close signal is provided to the conduit inlet gas valve so that a flow profile of the milk analysis quantity is controllable.
