• Maintenance Personnel: Inspect the Mini Roll Compactor for mechanical issues during the cleaning process and address any problems found.

4. Definitions

• Mini Roll Compactor: A machine used for compacting powder or granules into sheets or pellets for further processing.

• Cleaning Validation: A procedure to ensure that cleaning methods effectively remove contaminants from the machine without affecting the quality of the product or the integrity of the machine.

5. Procedure

5.1. Preparation

• 5.1.1. Shut Down the Machine:

  • Power off the Mini Roll Compactor and disconnect it from the main electrical supply to ensure safety during cleaning.

  • Lock-out and tag-out (LOTO) procedures must be followed to prevent accidental activation during the cleaning process.

• 5.1.2. Safety Precautions:

  • Ensure all personnel are wearing appropriate PPE (gloves, goggles, face shield, and lab coat) to protect against cleaning agents and debris.

  • Post safety signs to prevent unauthorized access to the cleaning area.

• 5.1.3. Remove Product and Waste:

  • Remove any remaining product, granules, or powder from the machine.

  • Dispose of any product waste and packaging material as per the company’s waste disposal guidelines.

5.2. Cleaning the Mini Roll Compactor

• 5.2.1. Disassemble Removable Parts:

  • If necessary, disassemble removable components such as rollers, trays, hoppers, and feed chutes as per the manufacturer’s instructions.

  • Handle all components carefully to avoid damage during disassembly and reassembly.

• 5.2.2. Dry Cleaning:

  • Use a dry cloth or compressed air to remove any loose powder, granules, or debris from all machine surfaces, including hard-to-reach areas.

  • Ensure that the air compressor is set at a safe pressure to avoid damaging sensitive components.

• 5.2.3. Wet Cleaning:

  • Prepare a mild cleaning solution using warm water and a non-abrasive detergent as recommended by the manufacturer.

  • Use a soft cloth, sponge, or brush to clean all machine parts that come into direct contact with the product.

  • Clean the rollers, hoppers, and feeding components to remove any residue.

  • Avoid soaking electrical components or areas that are sensitive to moisture.

• 5.2.4. Cleaning the Rollers:

  • The rollers should be cleaned carefully with a soft, lint-free cloth to remove any remaining product build-up.

  • If necessary, use a gentle scrubbing brush for stubborn residues, ensuring that no damage occurs to the roller surface.

• 5.2.5. Rinse:

  • Rinse all cleaned surfaces with clean water to remove any detergent or cleaning agent residues.

  • Be sure to remove any moisture from areas prone to rusting or corrosion.

5.3. Drying and Reassembly

• 5.3.1. Drying:

  • Use clean, dry cloths to wipe down all surfaces of the Mini Roll Compactor.

  • Ensure that all components are completely dry before reassembling them to prevent contamination and corrosion.

• 5.3.2. Reassemble the Machine:

  • Once all components are dry, carefully reassemble the machine according to the manufacturer’s instructions. Ensure that all parts are securely fitted and properly aligned.

5.4. Post-Cleaning Inspection

• 5.4.1. Visual Inspection:

  • Inspect the machine to ensure there are no remaining residues, cleaning agent traces, or debris.

  • Verify that all moving parts are free from blockages and that the machine is correctly reassembled.

• 5.4.2. Functionality Check:

  • Perform a quick operational test to ensure the machine is functioning properly. Check for any unusual noises or issues that could indicate improper reassembly.

5.5. Documentation and Verification

• 5.5.1. Cleaning Log:

  • Document the cleaning process, including the date, time, personnel involved, and any issues encountered during cleaning.

  • Record the batch number and machine status for future reference.

• 5.5.2. Verification:

  • A supervisor should verify that the machine is clean and safe to use before resuming production. Any discrepancies or problems identified during cleaning should be addressed immediately.

6. Health, Safety, and Environmental Considerations

• 6.1. PPE: Always wear gloves, goggles, and any other necessary PPE during cleaning to protect against cleaning agents and residues.

• 6.2. Chemical Safety: Ensure that all cleaning agents used are compatible with the machine materials and safe for handling. Follow all safety data sheet (SDS) recommendations for handling chemicals.

• 6.3. Waste Disposal: Dispose of waste products, cleaning agents, and packaging materials in accordance with environmental guidelines and the company’s waste management policies.

7. Monitoring and Auditing

• 7.1. Audits: Periodic audits should be conducted to ensure the cleaning procedure is being followed and that the machine is properly maintained.

• 7.2. Corrective Actions: Any deviations or issues identified during audits or inspections should be addressed immediately with corrective actions taken, including retraining or process adjustments.

8. Documentation

• 8.1. Cleaning Logs: Retain detailed cleaning logs for auditing purposes, linking each cleaning session to specific production batches.

• 8.2. Maintenance Reports: Document any mechanical issues identified during cleaning and communicate these to the maintenance team for corrective action.
