Star Refrigeration and its group business, Starfrost, have successfully worked in collaboration to install a new Helix Spiral freezer at James T Blakeman’s Millennium Way production facility in Newcastle-under-Lyme. Star delivered a cost-effective, energy-efficient and future proof turnkey refrigeration solution.
James T Blakeman & Co is a manufacturer of sausage and meat products, distributing 12,000 tonnes of products per year to clients both in the UK and internationally. An increase in product demand meant that James T Blakeman required a new spiral freezer unit and accompanying refrigeration system in order to facilitate an extension of its production capacity.
The project presented a number of challenges. Firstly, the new freezer installation was only one part of a wider upgrade to the entire facility. Secondly, with Christmas on the horizon and new orders to fulfil, James T Blakeman & Co specified that the cooling equipment need to be installed, commissioned and ready to use within 18 weeks.
The manufacturer also required production to be operational for 20 hours per day, leaving only a four-hour window for defrosting the freezer to ensure its coils were kept clear from ice build-up. The final challenge was that there wasn’t enough water onsite to allow water defrosting.
The customer’s commitment to health and safety determined that Star were to provide onsite support through the secondment of Leeds branch project manager, Luke Walsh, who was based at the Millennium Way site for the duration of the works in order to ensure successful completion of the project.
Star designed a bespoke solution that used all of its industry experience to deliver the best viable refrigeration solution for the customer. Benefiting from Starfrost’s expertise in freezing and chilling for the global food processing sector, Star provided a 50kW Helix Spiral freezer and refrigeration solution.
The combined technology is capable of meeting James T Blakeman & Co’s specifications of variable freezing between 100 degrees Celsius and -180 degrees Celsius with a retention time of 30 minutes, allowing for optimum flexibility. The system uses refrigerant R449A which has a global warming potential (GWP) of 1,397 and offers a cost effective, efficient and low GWP alternative that will ensure the plant remains operational for years to come.
Variable speed EC condenser fans were selected to reduce energy consumption during periods of lower ambient temperatures and to ensure smoother and more stable plant control. The plant also incorporates electronic expansion valves (EEVs) in order to allow the condenser pressure to vary and guarantee optimised performance all year round. To overcome the defrost challenge, Star used its patented four-way valve technology to deliver a reverse cycle defrost, ensuring that the system would be operational for 20 hours a day.
Philip Blakeman, director of James T Blakeman & Co, said: “We were impressed with the quality of the service Star could provide. Their ability to offer a competitive turnkey solution which covered all the bases, alongside the onsite expertise of Luke, gave us peace of mind and allowed us to continue to focus on our business operations.”
As the project progressed, Star’s Manchester branch undertook additional responsibility for the supply, installation and commissioning of two new refrigeration systems at the production hall and loading dock areas within the factory extension. Star also assumed the role of principle contractor and designer to provide a new dehumidification system for the coldstore roof void to tackle the build-up of moisture found on the insulated panels.
Brian Littleton, head of projects at James T Blakeman & Co, said: “From their initial advice and expertise in designing a completely brand-new system, to the rapid installation and capability to take on additional work to ensure the project was successfully delivered, Star Refrigeration have provided an excellent service.
“The team at Star have once again demonstrated their ability to go above and beyond our expectations and will now be helping us with the transition of all our existing R404A systems to a more environmentally-friendly alternative as well as taking on the maintenance contract for our site.”
