Italian fruit farmers store apples for energy -saving caves

[Global Times Comprehensive Report] In order to save energy, Italian fruit farmers store apples in caves.According to Reuters reported on the 21st, in a small town in the Torrenno area in Italy, local fruit agricultural caves as "natural refrigerators" are enough to store about 30,000 tons of apples. It is expected to further expand to 40,000 tons in the future.In the cave, the workers drove a forklift and transported apples, which is no different from the operation in ordinary warehouses.According to local fruit farmers, the existing caves can store 12%-13%of the local apple gains, and the cave comes with low temperature effects, which can save energy.

Before the cave is put into use, it is necessary to cool the rocks of the cave wall with gas, and then the temperature in the cave can continue to maintain 1 degree Celsius.If apples are stored with ground warehouses, apples are installed in the heat insulation boxes made of polyurethane and metal plates; and in the cave, apples can be placed directly in plastic boxes.Before the implementation of the plan, some fruit farmers expressed doubt, but the effect after implementation made fruit farmers generally satisfied.After the actual measurement of last year, the energy consumption of cave storage was 32%lower than that of ordinary storage.
