Abstract
382,890. Rotary drying drums. DUNCAN STEW ART & CO., Ltd., London Road Iron Works, Glasgow, ANIMAL FOOD PRODUCTS, Ltd., Felstead, Essex, and CROSBIE, J. B. TALBOT-, Raheen, Chesters Road, Bearsden, Dumbartonshire. May 6, 1932, No. 13086. [Class 34 (ii).] A revolving drum through which passes material subjected to the drying action of hot air or gas introduced through the circumferential wall of the drum is constituted as a perorated shell which is machined externally so as to be truly cylindrical and smooth. The drum may be formed in sections aligned and interconnected by flanged rings. The hot gas is introduced into the drum through elongated supply ports each of which is narrow circumferentially of the drum but may extend nearly the whole axial length of one division of the drum. The ports are framed with wide sealing flanges conforming closely to the curvature of the drum and approximated closely to the drum to minimize gas leakage. These flanges are constructed as or backed by ducts for cooling water, and may be faced with wired asbestos composition or like fibrous material. As shown in the drawings, the perforations in the drum 1 are countersunk on the inner surface, and the flanges 4 of the gas supply ports 3 are faced with fibrous material 5 and cooled by water entering by the port 6 and leaving by the port 7.
