FACMA’s dryers ES series offer a simple, cheap and necessary solution for the drying of woody shell products like hazelnuts, walnuts, almonds, chestnuts, etc. and has a capacity of 2,3m³ until 30m³ depending on the model.  The dryers can be loaded by conveyor belt or bucket elevator. The desiccation is obtained by the forced ventilation of hot air, which the heat-exchanger sends to the ventilator, which at the same time pushes it inside the body of the dryer. The product, continuously ventilated, is mixed by a central Archimedean screw and it can be ventilated also with non heated air. When the grade of humidity of the product is the requested one, the same product is extracted, by gravity, from the inferior part of the storage bin through the shutter and it is moved away by an adequate transport system. This process permits to considerably reduce the drying cycle, to maintain the product’s organoleptic qualities unchanged, assuring at the same time the worker’s safety in obedience to the laws in force.
