In refrigeration-free storage it is often necessary to move cereals from one store to another to ventilate the overheated product. However, the negligible temperature reduction (of 1-2 ° C) is accompanied by a product loss equal to 0.3% of the quantity handled as well as a significant increase in cracks and breakages due to the continuous handling of the product. To this must be added the energy consumption for transport facilities that can be quantified between 1 kWh and 3 kWh per ton of cereals, as well as the availability of one or more free sites for moving the product. With cold storage the need to move the product is completely eliminated.
