www.bryair.com Cold Storage Systems Cold storages can be divided into two main categories: Passive Stores � Built for storage of perishable goods for medium to long term period. � Typical Application Area - storage of fresh fruits and vegetables. Active Stores � Refrigerated warehouses required for dynamic storage applications. � Frequent movements of products on daily/ regular basis. � Various temperature zones are created within the same warehouse for storing of different products requiring different temperatures. � Typical Application Area – Ice Cream, Frozen food etc.
www.bryair.com Current Situation in India Passive Cold Stores � India has many passive cold storages for fresh fruits & vegetables as part of cold chain. To further support distribution of fresh fruits and vegetables these capacities are being created all across India. � At present no sorbtion technologies are being applied in these cold stores. Active Cold Stores � At present very little active cold storage capacity exist in India. � Limited only for special products and in metros. � With the distribution of various food products requiring cold storage facilities, this capacity will increase.
www.bryair.com Humidity Problems in Cold Stores
www.bryair.com Typical Problems in Active Cold Storage � 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 cartoons etc which causes cartons soften and sag making them unstable and hazardous to workers as well as un-markable. � Extra cost for defrosting and frosting.
