Summary: | 1330890 Concentrating solutions and suspensions BAYER AG 24 Nov 1970 [24 Dec 1969] 55744/70 Heading B1B A solution or suspension, e.g. a viscous polymer, to be concentrated is introduced under pressure through expansion nozzle 2 into screw evaporator 8 which it passes through, and the concentrated product is discharged at 25. Conveyor zones 16, 17 and 18 each comprise 4 conveying screws in V-formation, Fig. 2, and evaporation sections 19 and 20, which may be steam-heated, comprise kneading discs in V-formation. Evaporated solvent is drawn off at 5, 23 and 24, and during operation chambers 4, 21 and 22 are sealed from each other by the material being treated. Jacket 7 cools the walls of chamber 4 to form a liquid film on the wall. |
