CIP validation process / Riboflavin testing



Within the food, brewing, drink and pharmaceutical industries there is an ever present risk of product contamination that, if undetected, could result in product recalls, damage to brand names and, in the worst case, serious illness or death to a consumer.

Tests for examination of cleanability play a major role in sterile process technology.  Riboflavin testing provides a solution to validate the effectiveness of the CIP (Cleaning In Place) procedure.

 

Advantages include:

  • Validation of CIP installations in new equipment

Validating the CIP process / installation as part of F.A.T. (Factory Acceptance Test) or upon final installation.

  • Validation of modifications

In the case of modifications being carried out, the CIP validation provides certainty that the equipment is cleanable.

 

Riboflavin testing also provides solutions of what may be causing contamination as testing is the only proven way to efficiently monitor spray coverage, which is needed for a sanitary clean.

Common Issues affecting CIP cleaning

The most commonly issues connected with CIP cleaning:

  • Clogged spray devices;
  • Spray patterns that do not meet complex designs;
  • Damaged / missing spray devices;
  • Incorrectly located spray devices;
  • Design, pressure and flow rate inadequate for the design of the equipment;
  • Modified equipment;
  • Baffles, agitators or other obstructions causing shadowing / difficult to clean areas;

The INDEi CIP validation test is a fast and accurate test to examine the cleanability in new and operating equipment.  A solution containing water and a fluorescent vitamin covers all surfaces within the equipment.  The equipment is then flushed by completing the predetermined rinsing cycle.

Critical cleaning points are visible for the highly trained technicians using state of the art fluorescent equipment to verify the cleanability within the equipment.

  • Localises critical cleaning points that may cause hygienic risks / design flaws.
  • 100% food grade inspection, only using water and a known vitamin as the test solution.
