The invention relates to a device and method for milking animals, in which the milk which is removed is conveyed through a filter element. Any material which is deposited on the filter element is detected and, if appropriate, identified. After detection is complete, the direction of flow through the filter element is reversed, so that the filter material is rinsed clean. The invention also comprises a contamination meter for user in the device and method mentioned above.

1. Device for milking animals, comprising a milk line which runs from a milking cup to a storage tank, means for conveying liquid, through the milk line in a direction of flow, a filter element (7), which is positioned in the milk line, for filtering a flow of liquid (F1F2) which is flowing from the milking cup to the storage tank, and means (5, 6) for detecting material which has been deposited on the filter element, characterized in that there are means (10, 12) for reversing the direction of flow of the liquid through the filter element (7) while the direction of the fluid flow through the device remains in the same direction. 2. Device according to claim 1, characterized in that the means for reversing the direction of flow comprises a rotatably mounted filter element (7). 3. Device according to claim 2, characterized in that the filter is attached to a displacement means for rotation of the filter and which comprises a rotatable pin (10) and a drive (12). 4. Device according to claim 1 characterized in that the means for detecting material which has been deposited on the filter element (7) comprises a detector (6) for detecting radiation and a radiation source (5) for irradiating the filter element. 5. Device according to claim 4, characterized in that the detector (6) is positioned outside the milk line, and the milk line is provided with a window (3) for transmitting radiation from milk material deposited on the filter. 6. Device according to claim 1, characterized in that upstream of the filter element (7) there is a buffer chamber (15) for the buffered storage of liquid which is to be filtered. 7. Device according to claim 6, characterized in that there is a bypass line (17) between the milk line upstream of the buffer chamber (15) and the milk line downstream of the filter element (7). 8. Device according to claim 1, characterized in that means are provided for identifying animals which have been milked, as well as means for establishing the part of the udder from which detected material originates. 9. Device according to claim 1 further comprising a plurality of storage tanks at the end of said milk line, characterized in that said liquid is milk, and the milk line is provided, downstream of the filter element (7), with second storage means for storing milk for each milking operation, and with switching means for guiding milk from said second storage means to said plurality of storage tanks. 10. Device according to claim 9, in which said filter element is positioned in said the milk line between said second storage means and said plurality of storage tanks. 11. A method for milking animals with an apparatus having a milk line which runs from a milking cup to a storage tank and uses means for conveying liquid such as milk through the milk line with a direction of flow and in which a filter element is positioned in the milk line to filter the flow of liquid as it flows from the milking cup to the storage tank, a device to detect material which has been deposition the filter element characterized in that the direction of flow through the filter element (9) is reversed after each milking operation while the direction of the fluid flow through the device remains in the same direction. 12. Method according to claim 11, characterized in that after each milking operation and before the direction of flow through the filter element (9) is reversed, data concerning the contamination is detected and data representative of the source of the milk is stored in a control unit and is then linked to the identity of the animal from which the milk was taken. 13. Method according to claim 11, characterized in that after each milking operation and before the direction of flow through the filter element (9) is reversed, data concerning the contamination and the source of the milk is stored in a control unit and is then linked to the identity of the animals from which the milk was taken.
