Use Ice Pigging to increase product recovery in the food manufacturing industry
- Ice Pigging regularly exceeds 95% product recovery
- Ice Pigging reduces waste product and spoil
- Ice Pigging reduces chemical in CIP process
- Ice Pigging reduces energy (when applicable)
- Ice Pigging reduces water consumption
Our Nivalis Ice Pigging equipment is integrated into the factory control system and is fully automated to ensure saves time and increases the effectiveness of your system.
We have designed a standard machine for use in food manufacturing called The NIV500.
How does Ice Pigging clean pipes in the food manufacturing industry?
Once the factory’s process has completed and the line is ready for either cleaning or push out, the factory actions the NIV500 Ice Pigging machine to inject ice. The NIV500 automatically pushes ice to the purge valve, with the injection valve closed. This removes any melt which may have occurred to ensure a sharp product interface. Once the purge volume has been delivered the plant stops and alerts the factory that ice is ready for injection.
The machine then injects the correct volume of ice for the selected recipe. Upon completion, the factory receives a confirmation signal and can proceed to the ice propulsion stage.
The Ice pig is then moved along the pipe system under pressure. This task is undertaken by the factory and can be achieved using several methods: water push, or even using the next production run.
Once the Ice Pigging operation is complete [ice has been delivered into the pipe and ‘pushed’ through the pipe system ] the ice slurry will now also contain the waste material. This waste needs to be detected and disposed of (or in some cases re-worked). Detection of the ice pig is usually via a divert valve. This can then direct the ice pig to a separate collection point. Several options are available for interface detection, where possible sensors present in the system can be used. Suitable measurements include density, brix, conductivity, turbidity and temperature.
