Avoid moisture in your cold stores causing frosted products slippery floors, active cold stores are refrigerated warehouses required for dynamic storage applications. These warehouses have frequent movements of products on daily basis. Also various temperature zones are created within the same warehouse for storing different products requiring different temperatures. The application area are ice cream, frozen foods and cold storage of fresh fruits and vegetables.

Moisture Problems In Active Cold Stores

• Wet floors and ice build up on walls, floors and conveyors
• Ice build up on evaporator coils
• Frost build up near the loading docks
• Fog in the loading dock
• Moisture absorption by cardboard cartons causes them to soften and sag. This make them unstable and hazardous to workers as well as un-markable
• Defrosting costs
• Reduced storage space
• Frequent shutdowns
• Mould and mildew growth
• Decrease in the cooling efficiency due to water vapour loads and clogging of evaporator coils

Cold Chain

Cold stores are important elements of cold chains. The cold chain mechanism could involve storing perishable food items for considerable periods of time as well as long-distance transport. In order to prevent deterioration, fruits, flowers, vegetables, milk and processed food are first pre-cooled and thereafter stored in a cold store under conditions of low humidity. Cold stores are utilised even during the transit of the perishables from one place to another under conditions of low humidity. In the entire cycle of the cold chain, cold store serves as a vital link in preventing deterioration of perishables.

The mechanism of cold chain is simple. It involves maintaining food articles under conditions of low temperature for better shelf life and for little or no deterioration of perishables.
