Cleaning must be carried out once the machine has been defrosted and before it’s put back into production. The spiral freezer is cleaned either by automated methods (Full CIP) or manual cleaning procedures:
Automatic Cleaning System:
- Ensure all doors are locked and no personnel are inside the machine.
- Check that external conveyors are clear of personnel.
- Start the belt drive.
- Ensure all water and air supply valves are open.
- Select and start the cleaning program.
- Ensure water is draining properly.
Manual Cleaning:
- Stop the spiral belt.
- Remove or lower external conveyor hoods and trays to clean debris.
- Enter the machine and remove/open/lower conveyor hoods, trays, or belt covers to clean debris.
- Check for and manually clean any large pieces of product or debris buildup on floor levels.
- Refit all hoods, trays and belt covers to their original positions.
- Clean any debris from floors on both levels of the machine.
Water up to 60°C may be used, and a strong detergent with a neutral pH or mild alkaline that doesn’t damage stainless steel and aluminium surfaces should be used.
(CAUTION: Do not use high-pressure water hoses directly onto enclosure joints. Do not stand on the belt).
