Legal standard:- Pasteurised white milk must be heated to not less than 72̊C for not less than 15 seconds then immediately shock cooled to ≤4.5̊C. Export Control Orders (Milk and Milk Products) 2005 SC 5 DIV 3 Cl 16.1. Note: For Cheese, Check SC 5 DIV 3 Cl 17.1

• Is this legal standard stated on all White Milk HACCP flowcharts or tables. Diversion to be stated as 73̊̊̊C ( not 72̊C) due to instrument accuracy.

  Yes

• Calibration of thermometers and recording devices, including accuracy of time recording must be conducted every 6 months. Accuracy of thermometers must be +/- 0.5̊C.

  Yes

  No

  N/A

• As well as the diversion temperature sensing device, an indicating temperature device (or reference thermometer) must be installed adjacent to this instrument to enable the product temperature at the end of the holding tube to be observed during plant operation. The maximum deviation when compared to the diversion sensing device is +/- 0.5̊C at or around the normal temperature of operation. <br>If drift occurs both must be re-calibrated. <br>Review controlling and indicating thermometer records on log sheets and ensure corrective action has been taken if the difference is >0.5̊C.<br>

  Yes

  No

  N/A

• The Pasteuriser must not be operated at a faster flow rate than that stated on the 5 yearly Validation certificate.<br>Flowrate on audit day: <br>Certificate flowrate:<br>Date of Validation:<br>

  Yes

  No

  N/A

• Record of diversion valve reaction times must be checked yearly.<br>From temp probe at end of holding tube to PLC signal to valve lifting to full diversion (by feedback) position.<br>This must be recorded on Citec. Double diversion valves must be fitted with both primary and secondary valves diverting simultaneously. <br>After diversion and commencement of forward flow, secondary valve must not return to forward flow for 5 secs after primary.<br>There must be security in place to prevent unauthorised changes to Citect parameters.<br>Can Operators change settings?<br>
