Abstract: A milking system includes a milking device, a milk line, and a sampling and analysis device for milk from the milk line, that includes a control unit, a carrier with reagent pads to detect a substance in the sample, a dosing device to dose a sample onto a reagent pad, an sensor device to detect radiation from that reagent pad, and to analyse the detected radiation to indicate a presence or concentration of said substance. The dosing device includes a nozzle with a supply line, a pump for pumping liquid to the nozzle, a flat wall part, and a mover to press the flat wall part and the nozzle against each other to close the nozzle. In this way, the nozzle can be filled completely to a known level and without bubbles. Thereafter, the sample pump can provide a sample droplet with known volume, which enables better control over the sample supply process.

Abstract: A milking system includes a device to sample and analyse a milk sample, a sample supply line connected to the milk line, a pump to control the sample flow, an optical radiation source, and an optical sensor device to detect and analyse optical radiation coming from the reagent pad with said sample, to provide an indication of a substance in the sample, a tape mover to move and unwind the tape from the tape reel, and a pump drive releasably operably connected to the pump device for driving the pump device. The sampling and analysis device also includes a cassette with a sample receiving line to receive the sample from the sample supply line, a tape reel with a tape that includes a base tape layer and a series of separate reagent pads, and a dosing device to provide a droplet of the sample onto a reagent pad.

Abstract: A sampling device for taking a representative milk sample from a milking device. The milking device includes a milking means, a milk jar, a milk hose, a milk tank, a milk line, a milk pump for pumping the milk, a milk meter for determining the quantity of milk milked, and a control unit. The sampling device includes a sample line with an input connection to the milk jar, the milk pump or the milk line, an output to a sample collection receptacle, and a control device controllable by the control unit based on the quantity of milk determined by the milk meter in order to direct, during pumping, a sample quantity of milk through the sample line. The control unit knows how much milk must be pumped and can take precisely enough milk samples distributed over the pumping operation such that an accurate representative sample is obtained.

Abstract: A milking system with a milking device, a milk line, and a sampling and analysis device to sample and analyse the milk are disclosed. The sampling and analysis device includes a control unit, a tape wound on a tape reel, and including a base material with a series of reagent pads arranged to provide a detectable response in the presence of a substance in the sample, a tape mover to move and unwind the tape, a dosing device to provide a part of the sample onto one of the reagent pads, and an optical sensor device to detect optical radiation from said reagent pad with said sample, and to analyse the detected optical radiation to provide an indication of a presence or concentration of said substance. The dosing device includes a displaceable nozzle with a supply line for supplying the sample to the nozzle. The nozzle is arranged for supplying the sample upwardly to the reagent pad. The dosing device further includes a nozzle mover to move the displaceable nozzle towards and away from the tape, and an overflow device, or cup, including a wall that surrounds the nozzle. An overflow space is provided between the wall and the nozzle, and further includes a discharge. The overflow device can collect excess fluid, both when sampling and certainly when flushing. Herein, gravity helps in collecting fluid, but importantly, also in supplying the sample, since the sample droplet cannot break off the nozzle unexpectedly.

The sampling and analysis device also includes a cassette with a sample receiving line, releasably connected to the sample supply line by a liquid connector, and arranged to receive the sample from the sample supply line, a tape reel with a tape that includes a base tape layer and a series of separate reagent pads, and a dosing device to provide a droplet of the sample onto a reagent pad. The dosing device includes a nozzle in fluid connection with the sample receiving line, and a nozzle mover arranged to move the nozzle in at least a longitudinal direction. The cassette is replaceably received in the milking system. Hereby, a large number of parts that are subject to wear and contamination by milk residues are exchanged regularly, which improves measurement reliability and accuracy.
