A drying device for fertilizer, with a drying chamber (5) and an underlying heat chamber (3), has a condensing unit (20) for condensing the steam and gas formed in the drying chamber. A connection (25, 26, 27) is established between the condensing unit and heat chamber via the heat chamber's burner (4) for combustion of residual gas received from the condensing unit. The connection attaches to the burner's air intake. A ventilation fan (22, 23) is built in to expel steam and gas from the drying chamber to the condensing unit to create negative pressure in drying chamber (5).<IMAGE> |
