Perishable food especially fresh fruits and vegetables start to deteriorate as soon as they are harvested because they are cut off from their source of water and nutrition. They lose weight, texture, flavor, nutritional value and appeal. Cooling significantly slows down the rate of deterioration, thereby increasing the storage life of the produce.
ColdHubs, is a "plug and play" modular, solar-powered walk-in cold room, for 24/7 off-grid storage and preservation of perishable foods. It adequately addresses the problem of post- harvest losses in fruits, vegetables and other perishable food. ColdHubs, is installed in major food production and consumption centers (in markets and farms), farmers place their produce in clean plastic crates, these plastic crates are stacked inside the cold room. This extends the freshness of fruits, vegetables and other perishable food from 2 days to about 21 days. The solar powered walk-in cold room is made of 120mm insulating cold room panels to retain cold. Energy from solar panels mounted on the roof-top of the cold room are stored in high capacity batteries, these batteries feeds an inverter which in turn feeds the refrigerating unit.
