<strong>Canadian</strong> <strong>Quality</strong> <strong>Milk</strong><br />

• Clean residue from milk contact services according to guidelines set out by the<br />

service dealer, milk regulatory authority or refer to chart “Troubleshooting Films<br />

and Deposits on Equipment” in Chapter 11.<br />

• Review and revise SOP control measures to avoid a reoccurrence.<br />

• The following procedure can be used to remove the old build-up of fat, mineral,<br />

and protein on your CIP system during the wash cycle:<br />

Step 1.<br />

Step 2.<br />

Let the system go through the hot wash cycle, doubling the<br />

amount of detergent and adding the same amount of<br />

chlorine sanitizer.<br />

Reset the system to a second hot wash cycle, but replace<br />

the detergent by three times the normal acid amount.<br />

If equipment is still not clean, the process may have to be repeated.<br />

Remember: the sanitizer can only be mixed with the alkaline cleaner ⎯<br />

never with the acid.<br />

NOTE: After repeated exposure to high concentrations of detergent, rubber parts<br />

(i.e. liners) may have to be replaced. High chlorine content breaks down the inner<br />

protective coat of the liner.<br />

NOTE: Be vigilant in ensuring that the hot water system can deliver sufficient hot<br />

water to complete the above procedure.<br />

Reminder: All problems that occur regarding equipment sanitation and<br />

the corrective actions taken must be recorded on Record 13 or Record 17<br />

in the Workbook.<br />

See Chapter 7, Section 7.1 for more information on equipment sanitation.<br />

9.4.5 Water Temperature<br />

You must have a written corrective action plan for improper water temperature. Some<br />

possible actions are:<br />

• Check hot water heater to ensure it is functioning (e.g. one element may be<br />

burned out, faulty thermostat).<br />

• Check if the bulk tank was previously washed; thereby, exhausting the hot water<br />

tank and using all of the available hot water. If this is the case, wait and then rerun<br />

the wash cycle and check to make sure the temperature is adequate.<br />

• Check electrical breakers<br />

• Repair or replace hot water heater.<br />

• If the water heater works normally, call an equipment dealer to have the valves<br />

within the washer checked.<br />
