Dry Fog Humidity Control for Fresh Produce Cold Storage
Improve shelf life and product freshness with Fogging technology
Humidity Control for Fresh Produce Storage
Cold air is unable to hold as much moisture as warm air, as ambient air enters a cold store the air temperature reduces and the moisture falls out, condensing onto cold surfaces and the refrigeration coils. Although the air has a high relative humidity the actual moisture content is quite low.
The warmer ambient air absorbs moisture from the produce within the cold store which leads to weight loss and in turn financial loss. In addition, a lack of correct humidity results in a poor-quality product with reduced shelf life.
To avoid such a situation the installation of a humidity system controlled by a humidistat within a closed loop would maintain the desired humidity level at all times without over wetting the produce and other surfaces.
One of the biggest problems facing fresh produce producers and suppliers is finding ways to increase the shelf life and freshness of the product, whether it is potatoes or broccoli or carrots and fruits, all without compromising product quality and adding excessive costs.
Our Our ultra-fine fog humidity control system can accurately and economically control the relative humidity of a cold store to up to 99% rh, adding moisture into the atmosphere through millions of airborne water particles as small as 1 micron, but without the wetting of any storage equipment or floors.
The moisture created by the fog allows the product to hold its weight for longer, increase its shelf life and helps reduce the risk of disease. In potato storage it can also protect the potatoes from compression damage which reduces scrap and wasted product.
Our fog and micro-drop nozzles can also be used to dose in chemicals that stop the risk of sprout growth, again helping the products while at the same time controlling the rh. As we design and supply the complete liquid delivery and spray control package, we can offer either the standard humidity control systems, or a system with the added option of a chemical dosing system, meaning a dual purpose spray solution
