Beef Carcass chilling

A multinational food company specialising in the production of beef products awarded Seward Refrigeration Ltd a prestigious project to upgrade their existing NH3 plant to cater for an increase in beef production to hold in excess of 700 cattle, with energy efficiency and minimal product weight loss at the forefront of the project.

The additional plant consisted of an inverter driven Grasso reciprocating compressor, packaged surge vessel, replacement evaporative condenser to take care of the THR of the new and existing compressors, control panels and numerous evaporators/controls for the following areas:

Area 1	Area 2	Area 3	Area 4	Area 5	Area 6	Area 9	Total Load
Beef Chill N°4	Beef Chill N°5	Hot corridor/Weekend chill	Beef Chill N°6	Tripe Chill	Tripe Packing	Chilled red offal
216kW	136kW	272kW	216kW	25kW	17kW	40kW	922kW

A new discharge line de-superheater was installed for the two existing screw compressors and one new Grasso V1100 compressor, providing 405kw of heat during full load conditions raising the water temperature from +25°C up to +35°C for the warm water processes on site.

The new beef chilling evaporators installed were specifically designed for the process and through complex evaporator control via a detailed control strategy Seward Refrigeration Ltd have ensured a minimal product weight loss at less than 1.5%.

“The deserts project was a moveable feast being designed and procured very much on a just-in-time basis. The refrigeration package was awarded to Seward following a competitive tender process. As always, budget was the primary concern and Seward were proactive in providing solutions that suited the constraints of the programme and site as well as the Client’s finances.”

I can safely say up to that point I had not received such a professional, knowledgeable and effective service and was extremely happy with the whole installation, from initial scoping to the final sign off and commissioning.”
