Abstract

1,273,248. Evaporators, wiped-film type. LUWA A.G. 14 Nov., 1969 [15 Nov., 1968], No. 55913/69. Heading BIB. Powder is produced from a solution or dispersion of a solid in a liquid by introducing the solution or dispersion through inlet 30 into a vertical evaporation chamber 12 which is connected by member 18 to a horizontal drying chamber 14; the solution or dispersion is spread as a film on the hot inner wall of chamber 12 by elements 45 mounted on rotor 44 driven by motor 52, the paste passing through member 18 is spread as a film on the hot inner wall of chamber 14 by elements 58 mounted on rotor 54 driven by motor 72, the vapours of the evaporated liquid leave the apparatus through outlet 28, and dry powder is discharged through outlet 74. The wall of chamber 12 is heated by jacket 32; and the wall of chamber 14 is'heated by jacket 34. As shown the axes of the two chambers are at 90‹, but two other embodiments are disclosed wherein the drying chamber is inclined downwardly and upwardly, respectively, with respect to the vertical evaporation chamber. The connector member between the two chambers may be movable, so that the angle between the two chambers can be varied.
