IMPROVED DEHYDRATION SYSTEM COMPRISING A REVOLVING SCREEN

摘要

The invention relates to an improved dehydration system comprising a revolving screen, of the type which is used for the dehydration or drying of numerous types of agricultural products. The inventive system is characterised in that it employs: an improved revolving screen (4) comprising a sluice-free decantation unit (16), a mixed hot air generator (6) with two heating stages (8 and 12), and a double ventilating system (11 and 21) in order to improve the circulation of hot air inside the revolving screen (4). The invention affords the advantages of enabling the optimum drying of agricultural products with long fibres, while maintaining a high protein content and providing a significant reduction in the fuel consumption cost, given that low-cost solid fuels originating from agricultural residues can be partially used.
