What problems can dead zones inside a packaging machine cause?

• Dead zones trap product residue, breeding bacteria and failing FDA/CE hygiene certification.
• Residual material absorbs moisture and cakes, clogging the discharge path and lowering weighing accuracy.
• CIP/SIP cannot reach dead zones, forcing manual teardown at every changeover and extending changeover time.
• Corrosive residue stagnates in dead zones, accelerating pitting corrosion and shortening machine service life.
• Require a sanitary design drawing at FAT confirming no dead zones, full drainability and cleanability.
