Case Study: Muller Dairy Download case study as PDF (English) Download case study as PDF (Deutsch) Muller Dairy the UK's leading yoghurt manufacturer had a requirement to rapidly cool a whole range of palletized product to a dispatch temperature prior to moving to their cold store. They called upon Penmann's services, firstly to establish the optimum cooling method by undertaking product trials. They then were able to design and install a fully automated "in line" cooling tunnel to deal with the high levels of production throughput.

Penmann were also able to incorporate a number of key design features that were required by Mullers. Firstly, the tunnels have a narrow footprint to enable them to fit into conventional food production lines saving valuable production space. They were also designed to allow maximum access for ease of maintenance and also to minimize downtime. They were also designed with key mechanical features i.e. index loading of pallets to minimize air gaps and maximize cooling times and hence achieve maximum efficiency.

A second tunnel was soon required to deal with Muller's increasing output and when Mullers built their new factory a further four tunnels were ordered giving them an approximate cooling capacity of 130 pallets per hour.

Stephen Graves, Factory Engineering Manager stated, "We are very happy with the cooling tunnels designed and supplied by Penmann. All projects have been undertaken in an extremely efficient manner and have been delivered on time and on budget, and we have been particularly pleased with the performance of the tunnels".

Key Features

• Narrow footprint saving production space
• Reverse Air Flow to ensure even cooling
• Ease of access for on-line maintenance
• Indexed loading/static pressure cooling to ensure rapid chill time.
