Capital outlay will be recouped in just over two years. Beloit Walmsley is involved in the manufacture and refurbishment of paper-making machinery and is a division of the USA based heavy engineering organisation Harnischfeger Industries. The original heat pumps for the Lincoln-based 1950's building had become noisy and unreliable, failing to cope with the modern demands of a factory where 180 staff handle 11 million eggs weekly. The lighting system was also inefficient and expensive to operate, with the heat given out placing further strain on the cooling system. Clean air is supplied at low velocity and low level from special diffusers.
Cool air flows in a pool across te floor, rising to between waist and shoulder height.
Warmth generated by staff and machinery heats the air, causing it to rise. Extraction at a high level completes the cycle, carrying away contaminents and spent air. The close monitoring of temperature control throughout the cool chain' production cycle extends the egg storage lifetime, making air displacement systems ideal for food handling applications. Extensive filtration of the cooled air enables efficient recycling, and the dramatic reduction in air-borne dust has reduced cleaning costs. Daylay Foods Limited is part of Hillsdown Holdings.
