By comparison with fixed bed dryers, fluidized bed dryers operate at higher air velocity, making the product to suspend and become fluidized. This improves greatly the contact between material and hot air, enhancing heat and mass transfer and consequently improving energy efficiency. However, they are rarely used by smallholders in developing countries. That is because the design and construction of fluidized bed dryers are more complex, particularly the fan, that needs to be properly dimensioned to be able to correctly fluidize the product.
Moreover, in developing countries, fuel cost is the main expenditure of processing centres. At those centres, the building where the dryer is located is usually covered with a pitched roof. To reduce the use of fossil fuel, those roofs could be adapted to work as solar collectors and preheat the drying air. Auxiliary heating would still be needed to assure reaching the correct drying temperature and to allow operating under overcast conditions, nevertheless, converting a dryer to a solar-assisted equipment brings great economic and environmental benefits.
