Device for emptying a milk line

The invention relates to a device for emptying a milk line in a pipe milking system, whereby the milk is pumped from a lower milk separator through the milk line into a higher milk tank.

Such a device is known, for example, from DE-OS 25 48 601, where a milk filter lock is provided at the end of the milk line, which is subjected to negative pressure via a separate line and a switching valve after the milking process has ended, thereby draining the milk line against the force of gravity. A sponge inlet nozzle is provided so that the milk column in the milk line does not break off. The sponge pushes the milk column in front of it during the emptying process. However, a film of milk can remain on the inner wall of the milk line, which flows back to the lowest point of the milk line. Complete emptying is then not guaranteed. The installation effort is also considerable for widely branched pipe milking systems.

The invention is based on the object of creating a device with which the milk line can be completely emptied without using a sponge with a milk filter lock and which does not require any additional installation effort.

The task is solved by connecting a drain nozzle provided at the lowest point of the milk line via a first line to a control milking cover mounted on a container, which is connected to a milking line via a second line.

A negative pressure is built up in the container via the second line and the control milking cover and the milk line is thereby drained via the first line. I

parts is not possible. Also, no milk column can collapse, since it is sucked in the direction of gravity.

and therefore no sponge is required.!

Control milking caps with the associated pipes and containers are required in milking systems to examine the milk of individual cows and are usually present in every milking system, so that no additional installation effort is required.

A standard milk transport jug or a bucket milking vessel can be used as a container.

The first line can be connected to the lowest point of the milk line particularly easily if a drain nozzle designed as a milk pipe slide is provided at this point.

An embodiment of the invention is shown in the drawing and is explained in more detail below.

In the drawing, 1 designates the milk separator, _to which the milk flows via the milking line 2. The milk separator 1 is connected to a vacuum line 4 via a safety separator 3. The milk is drawn off from the milk separator 1 by means of a pump 5 and pumped through the milk line 6 into a higher milk tank 7. At the lowest point of the milk line 6, a drain nozzle 8 is provided, which is designed as a milk pipe slide. A milk filter 9 is arranged immediately in front of the drain nozzle 8.

After completion of the milking process, the emptying nozzle 8 is connected via a first line 10 to the control milking cover 11, which is mounted on a container 12.
A second line 13 leads from the control milking cover 11 to the milking line 2, which is under negative pressure. The negative pressure from the milking line 2 is transferred to the container 12 and thereby causes any milk still remaining in the milk line 6 to be sucked out via the first line 10.
Since the milk is sucked out at the lowest point of the milk line 6, its complete emptying is guaranteed.

The arrangement of the milk filter 9 in front of the discharge nozzle 8 also ensures that the remaining milk is filtered.
