Abstract: 963,950. Drying in electric fields. BADISCHE ANILIN- & SODA-FABRIK A.G. Oct. 9, 1962 [Oct. 17, 1961], No. 38112/62. Heading F4G. An apparatus for the continuous drying of powdery or granular materials in an H.F. field comprises a tube of insulating material mounted between H.F. electrodes and having a feeder drum of larger diameter at the feed end and means for rotating the tube and drum in a substantially horizontal position, the material passing through the tube in a constant direction. Apparatus for the continuous drying of granular or powdery material comprises a tube 1 of polyester resin and glass fibres between H.F. electrodes having a feeder drum 8 of greater diameter at one end formed substantially as a double cone, which tube and drum are rotated in a substantially horizontal position by a variable speed motor 6. The inner face of tube has baffles 10 parallel or inclined to the axis of rotation, and the feeder drum 8 has fillets or curved blades 11, the faces of the tube and drum and the baffles and fillets being lined with polytetrafluoroethylene which may be reinforced with glass fibre. The tube is mounted in bearing plates 2, 2 1 mounted on a frame 3 which is hinged at 4 to raise or lower the delivery end of the tube by a threaded spindle 5. The angular position of the electrodes relative to the axis of rotation of the tube is adjustable between 30 and 180 degrees (Fig. 2, not shown) and the distance of the electrodes from the wall of the tube is variable. The delivery end of the tube leads into a receptacle 15, a fan 14 and cyclone separator being provided.
