The European Frozen Food business is reported to be in excess of €75 billion* and all indications are of strong continued growth across all the markets. The vast majority of those products, together with those in the Chilled Foods sector, will spend significant time being transported or stored on pallets.
Let´s have a look at how modern automated systems can help ensure these packaged products stay within the required temperature range, from the moment they leave the production line, until they are stacked on a pallet and stored in a cooled warehouse or loaded into a truck.
Typical frozen/chilled product categories:
- Ice cream, dairy products, yoghurts
- Frozen vegetables, french fries
- Frozen bakery products, morning goods
- Red meat, poultry, fish
Focus on advanced tracking and reducing energy consumption
With the need to maintain low product temperatures an absolute necessity, combined with a robust traceability system, the process of securely palletising and conveying these frozen or chilled products created a need for dedicated fault free tracking solutions, both to ensure there is no interruption to the cold chain and to provide full traceability for each product and/or container.
The Scott Multi-line system ensures that there is a zero chance of mixing SKUs as each product batch is buffered and transferred to its dedicated pallet in isolation. Product ID and count are integral parts of the system which tracks each SKU through to the pallet build, pallet wrapping and automatic labelling, displaying the relevant bar coding. The tracking information is then available for transfer to the customers database as part of their traceability recording requirements. This also provides proof that each product has spent the minimum time needed outside the deep freeze for the palletising cycle to be completed.
Such solutions need not only to ensure the quick handling of the products and full pallets, but also reflect;
- Growing pressure on reducing the energy consumption – every m³ to be cooled means significant costs, so the aim is to minimize the space needed for the handling equipment.
- High reliability by keeping sensitive system elements at ambient temperature.
What to consider when planning an automation project
It starts with full understanding of the products to be packed, following the requirements for storing products at the right temperatures in order to ensure the product quality: (deep freeze, refrigerated, cold/cool).
Recommended Techniques:
- Buffer pallet loads: Products buffered in block to keep the products at the required temperature for as long as possible.
- Minimize time outside required temperature zone area to palletise: create pallet in 1 min, stretch wrap and label, transfer back to freezer.
- Sensitive technology such as electronic elements, operator panels, measuring equipment, etc. should be kept outside the freezer.
- Tracking of the pallets loads (full pallets): monitor and record how long outside of required temperature zone.
Multi-line palletiser with pack buffering as a preferred solution
Scott Automation developed a proven answer to this need, with clever Deep Freeze or Chilled Buffering, Product Handling and Multi-line Palletising Systems that maintain the integrity of frozen and chilled food products from the production line, through to low temperature (down to -25 °C) storage warehouses or delivery trucks.
The multi-line palletiser serves several production lines and is located in a separate area outside the freezer at ambient temperature. The packs are buffered on tables inside the freezer, then as soon as there are enough packs ready to fill a complete pallet, the system calls them up and conveys them to the palletiser. The full pallet is then transported quickly back to the freezer again.
Compared to end-of-line systems, this solution requires less space and fewer palletizers (multi-line solutions usually consist of one or two machines). The result is a simplification of pallet flows and a significant reduction in forklift movements. In addition, the real ‘buffer zone’ represented by the accumulation tables, allows the system to guarantee a better output from the production lines. All these factors, combined with a reliable and proven solution, contribute to substantially reduce the cost of ownership.
