Webwere fluidized at three different dryer positions: vertical bed (0° inclined), 15° and 30° inclined beds with drying air temperatures of 55°C, 60°C and 65°C and air velocities of 1.1 ms-1 and 1.6 ms-1. The blower was switched on and air mass flow rate and velocity were adjusted by means of a gate valve installed in the air flow pipe.

Rotary Disc Dryer Indirect Steam Dryer - TG MACHINES
WebMar 28, 2006 · Abstract. The wake of a disk at an angle to a stream contains marked periodic motions which arise from the regular shedding of vortices from the trailing edge. The vortices are in the form of a chain of irregular rings, each one linked to the succeeding one, and they move downstream at about 0·6 of free-stream velocity. WebThe HUBER Disc Dryer RotaDry® convinces by its compact design, which allows the dryer to be installed even on a small footprint or to be integrated into existing plants. The many years of successful use of disc dryers in combination with sewage sludge incineration plants demonstrate the robust technology of the process.
