We are commonly asked about "wet testing" a milking plant, and the name is also used quite widely, but true wet testing is probably not what most people are referring to when they use that description.
There are actually five types of milking machine tests recognised by Countdown and the IDF (International Dairy Federation):
- Physical measurements are all about the “nuts and bolts” of the milking plant. They include the type and sizing of components and the matching of components to given specifications. This test is done without the machine running.
- The standard AMMTA test or "dry" test is the most common test conducted on milking plants in Australia. It is conducted both with and without the plant running, but without any liquid flowing through the pipelines. This test records air consumption of components, vacuum levels, vacuum reserve capacities and pulsation recordings. It also includes the physical measurements described above. This type of test indicates how the plant performs mechanically, but does not measure how it performs under load when actually milking.
- "Wet" testing of milking plants is where an artificial udder is used to test the plant with both liquid and air flowing through it to simulate milking. This is a good diagnostic and trouble shooting tool, and can be used to give an idea of how the plant is likely to perform at specific milk flow rates.
- True milking time testing is the only way of knowing just how the plant is performing under the load of actual milking with cows and milking staff in the dairy. It is also the best way of measuring the vacuum that cows are actually experiencing during milking.
- Cleaning-time tests assess the cleaning process.
Milking time testing is one of the key components of every Dairy Focus Mastitis Risk Assessment of a dairy and allows fine tuning of milking machine settings, such as the vacuum level, to suit each individual herd and milking system.
Farms enrolled in the Dairy Focus Mastitis Control System have regular Mastitis Risk Assessments - thus their milking system has regular milking time testing in addition to standard AMMTA "dry" testing.
