Operational Advice: CIP Cleaning

Operational Advice: CIP Cleaning

The single most important step in keeping your equipment running, is to clean it properly at the end of each process day.  Even with this importance, CIP cleaning is likely the most neglected aspect of operating MicroThermics processors.




In general, a proper CIP cleaning process includes:

  1. Water flush (rinse)
  2. Caustic recirculation (15-20 minutes commonly)
  3. Water flush (rinse)
  4. Acid recirculation (15-20 minutes commonly)
  5. Water flush (rinse)
  6. Inspection to ensure equipment is clean.

Ideally these are all accomplished at flow rates to reach velocities of 5’/second, or the maximum flow rate of the equipment, and at temperatures of approximately 145˚F-160˚F.

However, specific CIP procedures should be developed by the users of the equipment to clean their specific products and equipment.  These procedures should include using the right cleaner for your products, as well as cycling all necessary in-line valves to ensure that ALL product lines exposed to your products are properly cleaned and rinsed.  Finally, at the end of the CIP process, don’t forget to inspect areas of the processor to ensure it has been cleaned properly.

Please note that CIP cleaning is actually something that is designed into a processor, not just something done by the operators.  If a processor is not designed properly, improper heating, low velocities and burn-on can prevent effective CIP cleaning of the equipment.
