Cold Store Operation Enhanced at Eyemouth Freezers Through Installation of Localised Dehumidification Air Curtain System (Food Related)
- Build Up Ice and Frost Significantly Mitigated
- Need for Defrosting Cycle Significantly Reduced
- Site Operation and Productivity Enhanced
Roflow have successfully completed the design, manufacture and installation of a comprehensive dehumidification scheme at Eyemouth Freezers; significantly mitigating the rate of frost build up within the cold store. The Roflow system incorporated a Munters Ice Dry 1400 Unit in which delivers a constant localised curtain of dry air over the freezer doorway, reducing the rate of cold store air saturation during daily operation. The saturated air from within the cold store is also taken away and ejected through a cowl to outside, ensuring constant delivery / circulation of dry air within the store itself.
Eyemouth Freezers Ltd are an independent food processing company based in the South-East of Scotland in which specialise in the IQF freezing and packaging of peas; producing 1.2 million packs per month (equating to 220 tonnes per day). Eyemouth Freezers’ 10,000 pallet cold store is a vital component of their operation, and constant cold store defrosting can have a substantial impact on production.
The Munters Ice Dry 1400 was appropriately selected for this application as it is the only dehumidification unit in which has been especially developed for installation inside the tough, cold environment of a cold store. As already mentioned, the moist air from within the store is taken away and discharged outside via a cowl. The reactivation / replacement air is taken from the repack room next door and dehumidified prior to being delivered via a localised air curtain over the cold store opening.
Large numbers of loadings into the cold store means many openings of the doors to outside which allows moist and warm air enter into the freezer and will cause snow and frost formations on refrigeration equipment and sensors affecting efficiency as well as disturb barcode readings and cause packing materials to soften. Ice and frost also build up quicker on the walls, meaning more production disturbing defrosting cycles are necessary to remove the ice.
The installation of this system Significantly reduced the need of a defrosting cycle enhancing their production and cold storing capabilities.
