College Students Invent A Cooling Shed System To Preserve Harvested Produce

September 9, 2010: 02:46 PM EST
Students at a U.S. agribusiness college have developed a way to make their own fruit and vegetable harvest remain fresher longer. The students built two 10-foot-by-10-foot air-conditioned walk-in packing sheds on the 450-acre farm property, providing a sustainable and cool way to preserve the harvest. University and state officials worked together to secure $34,300 in state agriculture enhancement money. The university contracted with an air conditioning firm to build the packing sheds and provide the geothermal method: digging a 6 1/2-inch hole 300 feet into the ground adjacent to the shop facility housing the packing sheds. The method brings a constant 55-degree temperature to the cooling units. “It’s 70 percent more efficient and doubled the lifespan of the cooling unit,” one of the students said.
