Abstract (en)

[origin: GB2465361A] A method of drying or processing materials in a drying or processing cylinder, or other drying or processing apparatus, located within or forming at least part of an enclosure 1. At least a portion of a process gas entering a higher pressure region 4 of the enclosure is routed by a fan 2 through a venturi and around, over, across, through or adjacent the open end of a material input tube 7 at increased speed and reduced pressure. This provides suction at the opening of the material input tube into the higher pressure region of the enclosure which is sufficient to prevent, or substantially prevent, the pressure at the higher pressure region of the enclosure causing the process gas atmosphere in the enclosure to be blown through the tube and out of the enclosure into the external air or other gas atmosphere outside the apparatus. Preferably, the venturi is defined by an annulus formed by the material input tube located coaxially within a process gas duct 6, 8. The speed of the fan may be controlled. In a further aspect, an associated apparatus is disclosed.
