Abstract: 1,145,784. Extracting sugar. BRAUNSCHWEIGISCHE MASCHINENBAUANSTALT. Aug.24, 1966 [March 25, 1966], No.38008/66. Heading C6B. In a method and apparatus for extracting sugar from sugar-containing material, particularly crushed and sliced sugar-cane, the material is fed, from a hopper 7, Fig. 1, into the trough 5 of a counter-current diffuser 2 having a base in the form of a fixed screen 6. The upper flight of an endless, travelling drag-chain conveyer 13 conveys a layer of the material on the screen 6 under spraydistributers 12, which spray aqueous extracting liquid, circulated by pumps 9 from collecting tanks 8 through pipes 11, on to the material, then under a rotating, material-loosening or tearing roller 20 and more spray-distributers 10, which spray aqueous liquor from a tank 18 (hereinafter referred to) on to the material, and then under a partition roller 28, which applies pressure to the material and prevents substantial escape of liquor from the end of the screen 6, where diffused material is discharged, with the aid of the radial arms 27 of a rotating throwing-roller 26, on to a fixed screen 17, Fig.2, constituting the base of a press 16, Figs.1 and 2. A layer of material, e.g. thinner by 50% than the layer on the screen 6, is carried along the screen 17 by the upper flight of a travelling, endless drag-chain conveyer 21, which travels faster than the conveyer 13. Liquid is expressed from material on the screen 17 by one or more rollers 24 journalled in a frame 23, which can be swung up or down, about a pivot 23 by a ram 25, e.g. a hydraulic ram. Liquid percolating downwards through the newly formed layer of material, before it reaches the roller or rollers 24, effects some after-diffusion, which is completed by the liquid, e.g. press-water, which is expressed by said roller or rollers. Percolated and expressed liquid is collected in a tank 18. Assisted by the radial arms 32 of another rotating throwing-roller 31, the pressed material, e,g, bagasse, is discharged from the screen 17 on to a travelling endless conveyer 33, which feeds the material into one or more roller-presses or mills 29, which squeeze more aqueous liquid, e, g, press-water, from the material. According to the description relating to Fig. 3 (not shown) the upper, rollersupported flight of an endless travelling screen-belt conveyer (35) may be used instead of the screen 17 and drag-chain conveyer 21, and an arcuate pressure plate (38), which can be swung up and down about a pivot by a hydraulic ram (30), may be used instead of the partition roller 28.
