What should determine the cleaning frequency of a packaging machine?

• Set frequency by residue risk of product-contact parts: powders/sauces per shift, dry granules weekly.
• Base it on fouling rate of heat-seal jaws, formers and feed tubes; film debris or burnt buildup shortens the cycle.
• Follow product changeover: full CIP or teardown cleaning required for allergen or color switches.
• Adjust per microbiological swab results; exceed TVC limits triggers more frequent validated cleaning.
• Use the OEM manual and CE/FDA hygienic design level to define daily, weekly and monthly cleaning tasks.
