Marel recommends the following sanitization procedure:
l Spray the sanitizer on surfaces and leave to work according to manufacturer’s instructions.
Make sure you spray into all corners and hard-to-reach areas.
l After sanitizing, always rinse the controller carefully with cold and clean water before
resuming processing.
l Use chlorine or a comparable sanitizer on the controller once a week after performing the
regular cleaning procedure with a high alkaline foaming detergent.
l Make sure the strength of chlorine, if used, does not exceed 200 ppm.
l On days when chlorine or a comparable sanitizer is not used, use other sanitizers recom
mended for food processing instead.
NOTE
Rotating different sanitizers (for example chlorine, peracid or acid-anionic) in your san
itization program may ensure more effective sanitization.
As chlorine evaporates very quickly, its sanitizing effect will fade soon after it is sprayed on the
equipment. Letting chlorine stay on the equipment will not improve the sanitizing effect, but
only damage the equipment. Quaternary ammonium compounds are considerably more
stable than chlorine and are active for a much longer time. Therefore, the benefit of leaving
QACs on the equipment for an extended period of time is much greater.
Training Staff
It is important that new cleaning personnel receive the proper training and are made aware of
the proper cleaning procedures for this equipment. Demonstrate the cleaning procedures for
new personnel using the instructions in the following sections. Make sure the cleaning per
sonnel are familiar with safety rules concerning the use of cleaning agents.
Final Inspection
After cleaning, quality control personnel should evaluate the result of the cleaning process:
l Using your hands, ensure that places are clean where visual control is difficult.
l Regularly measure cleaning results by counting the microorganisms, for example using
RODAC cups or ATP measurements.
l After cleaning and sanitizing, make sure that all surfaces dry as well as possible.
Special Cleaning Instructions
NOTE
Cross-contamination can easily occur if clean surfaces come in contact with other less clean
surfaces.
