As agricultural and livestock production continues to increase globally, new strategies must be implemented to store food before it is brought to market. According to the United States Department of Agriculture in 2018, nearly all frozen and refrigerated food stocks were up from a year ago. Consumers continue to demand a wide variety of frozen and fresh products, from poultry to pecans. In the United States alone, there are over 800 commercial and public warehouses that store refrigerated products. All frozen and refrigerated food must be held somewhere before it can be put on trucks and brought to local communities. Thus, cold storage is a critical part of the food processing cycle.
Maintaining optimal relative humidity in cold storage is essential to ensuring longevity of food products. Many food products, especially produce, require higher humidity levels while in storage or they suffer from a loss of water volume. Water loss directly affects the bottom line, reducing overall weight and often resulting in a loss of quality through wilting, shriveling and/or changes in texture. In this way, storage facilities lose out on valuable profits. A humidification system allows for total control over the moisture levels in the cold storage facility and can help ensure efficient and profitable storage.
