It is important to undertake a visual inspection of the equipment to ascertain the current condition of components and the effectiveness of cleaning. The objective is not to assess the performance of the components – although some inferences could be made by their presentation – but rather the ability of their milk contact surfaces to stay ..
Flow through the cluster Check to see that cleaning solution is flowing through every milking unit (cluster). The flow should be turbulent and similar between clusters. Lack of turbulence despite apparently good flow may indicate a blocked/restricted air bleed in the cluster. Check and clear if necessary. Air leaks between the liner mouthpiece and the ..
Ensure PPE is worn. A chemical test kit is required to assess whether the chemical characteristics comply with the requirements for effective cleaning. The test should be conducted on cleaning solutions that have been made up but not used. The tests to conduct are given in the Table below. Chemical test parameters for cleaning solutions ..
Water Sources Identify the (current) sources of water that supply both the hot water service(s) and cold water taps. Be mindful that different sources may be used for different cycles of the wash. For example, bore water may be used for the pre-rinse cycle and rain water used for all other cycles. Water Quality Results ..
Make notes of recent changes to: Milking equipment – recent upgrades, replacement of components (e.g. vacuum pump), repairs or breakdowns, major services. Flooding of the system – during milking or during cleaning. Cooling equipment – changes to cooling equipment, changes to temperature of the milk entering the bulk milk tank, plat cooler pump issues, water supply issues, cooling ..
Clearly describe the problem as it currently presents. Has the investigation been initiated by a high Bactoscan result, Thermoduric count, other factors (e.g. visible cleaning failure) or a combination of all? Provide plenty of details about history, circumstances, and what the objective(s) for the investigation might be. Provide the latest Bactoscan/TPC and Thermoduric test results. Test ..
