  • Prepare a mild cleaning solution as recommended by the manufacturer. This may include a mixture of warm water and a non-abrasive detergent.

  • Use a soft cloth or sponge to clean all accessible surfaces of the EPD Collator.

  • For stubborn residues, use a gentle scrub brush or cleaning tool.

  • Rinse with clean water to remove any detergent residues.

• 5.2.4. Drying:

  • Use a lint-free cloth or allow air drying to ensure all surfaces are dry before reassembling the parts.

5.3. Cleaning the Strip Packing Machine

• 5.3.1. Disassembly:

  • Disassemble removable parts such as the strip feed, rollers, trays, and any other components that come into contact with the product.

  • Follow the manufacturer’s instructions for disassembly and cleaning of the packing machine.

• 5.3.2. Dry Cleaning:

  • Use a dry, clean cloth or an air blower to remove any visible particles, dust, or debris from the machine.

• 5.3.3. Wet Cleaning:

  • Prepare the cleaning solution (mild detergent with water), as per the manufacturer’s recommendation.

  • Clean surfaces, conveyors, and any areas that might have direct product contact using a soft cloth or sponge.

  • Pay extra attention to areas with product build-up, such as sealing zones or feeding sections.

• 5.3.4. Use of Brushes:

  • Use a non-abrasive brush to clean hard-to-reach areas or spots with stubborn residues.

  • Be careful to avoid damaging sensitive components or seals.

• 5.3.5. Rinse and Dry:

  • Rinse thoroughly with clean water to remove any detergent residue.

  • Use lint-free cloths or allow parts to air dry completely.

5.4. Cleaning of Auxiliary Equipment

• 5.4.1. Conveyors and Trays:

  • Clean all associated conveyors and trays with a mild detergent solution and rinse well. Ensure there is no contamination from previously processed material.

• 5.4.2. Control Panels:

  • Use a damp cloth to gently wipe control panels. Ensure no water or cleaning solution enters the electrical components.

• 5.4.3. Other Accessories:

  • Clean any other accessories like bins, bins trays, or chutes, using appropriate cleaning solutions and methods.

5.5. Post-Cleaning Inspection

• 5.5.1. Inspect for Residues:

  • Ensure that no cleaning agents or residues remain on any parts of the machines.

  • Perform a visual inspection for cleanliness and check for any leftover debris or buildup.

• 5.5.2. Reassemble Equipment:

  • Once the machine and parts are completely dry, reassemble all components, following the manufacturer’s instructions.

• 5.5.3. Calibration:

  • Ensure that the machine is properly calibrated after cleaning, especially if the machine uses sensors, feeders, or temperature control.

5.6. Documentation and Verification

• 5.6.1. Cleaning Log:

  • Record the date and time of cleaning, the personnel involved, and any issues encountered during the cleaning process.

  • Document any adjustments made during cleaning and note if any repairs were needed.

• 5.6.2. Post-Cleaning Testing:

  • Perform any necessary testing or sampling to ensure the equipment is functioning properly before resuming production. This may include checking for product integrity, alignment, and machine function.

• 5.6.3. Final Approval:

  • Supervisors must verify that cleaning is complete and that the equipment is safe to restart. Final approval for resuming production must be obtained.

6. Health, Safety, and Environmental Considerations

• 6.1. PPE: Always wear gloves, goggles, face shields, and any other required PPE during cleaning.

• 6.2. Chemical Safety: Ensure that all cleaning agents used are compatible with the materials being cleaned and that they are disposed of according to environmental and safety standards.
