| titleOfInvention | Solvent extraction process and apparatus therefor |
| abstract | In a process and apparatus, Figs. 1 and 4, for the continuous, countercurrent extraction or diffusion of a soluble substance such as sugar from subdivided solid material, such as sugar-beet or sugar-cane, the material is fed, as by a travelling belt 40 and a distribution scroll 42, into an annular trough 5 having inner and outer cylindrical walls 22 and a flat, e.g. perforated, draining base 24. The trough 5 is supported on rollers 15 and mounted on a slowly rotating central shaft 2. The material is thus distributed around the trough as a bed having a substantially horizontal upper surface. Extracting liquid, e.g. a mixture of fresh water, from a pipe 121, and water expressed from spent material delivered through a pipe 122, is circulated by a system including distributers S to S16 and S17, pumps P1 to P17 and tanks T1 to T17, so that it makes progressively a series of downward percolations through the rotating bed and the base 24. The resulting solution or extract is collected in a tank T18 beneath the material-receiving part of the trough 5. Spent material is removed from part of the trough above the tank T1, e.g. upwardly, as by mechanism including an elevator 52 and a scroll conveyer 55, or downwardly, as by mechanism described in relation to Fig. 6 (not shown). The distributers S to S16 each comprise a radial trough 90 provided with outlet openings 117 for distributing the extracting liquid. Substantially the same quantity of liquid is collected in each of the tanks T1 to T17. The distributing troughs 90 are secured to inner and outer, circular, roller-mounted tracks, which can be turned around the shaft 2, so that all the troughs 90 can be moved together over and around the annular trough 5. <PICT:1066791/C6-C7/1> <PICT:1066791/C6-C7/2> Chlorine, formaldehyde or sulphur dioxide may be used in the process to control the growth of bacteria. The solid material is subdivided, preferably, by being passed first through dividing apparatus described in Specification 1,066,793 and then through fiberizing apparatus described in Specification 1,066,792. |
