Abstract

1,182,321. Mixing apparatus; evaporators, film type; dispersing apparatus; comminuting apparatus. H. LIST. 27 Jan., 1967 [28 Jan., 1966], No. 4252/67. Headings B1B, B1C, B1V and B2A. [Also in Division B5] In an apparatus and process for mixing, dispersing, pulverizing, evaporating and degassing, the material is formed into a thin film the thickness of which is continuously varied between two elements having relative vibratory and rotational movement. In Fig. 1 a rotatable member 10 comprises cylinders 11, 12 interfitting with cylinders 21, 22, 23 of a member 20 which is diametrically reciprocated or vibrated as well as being slowly rotated. Material enters at 25 and is discharged at 34 after following a tortuous path between the cylinders. The working surfaces have helical grooves 14 which assist progress of the material and may be deeper at one side to generate additional shear forces. The members 10, 20 have channels (not depicted) for a heat transfer medium; the member 20 may be raised by hydraulic or pneumatic jacks 30 and pivoted on trunnions 41 for cleaning. In a modification (Figs. 3 and 4, not shown) the member 20 performs an orbital motion while a screw (18) assists flow of material which is pressed through discharge orifices (19) as strands which are severed by a fixed knife (69). In another embodiment (Figs. 5 and 6, not shown) the member 20 is fixed to the casing of an extruder screw 26 while the member 10 has combined rotational and orbital motion. When embodied as a thin film evaporator (see Fig. 7, not shown) the cylinders of the upper member 20 are longer than those of the lower member 10 and the member 20 has an annular collecting channel (90) for vapour and a discharge outlet (91). The members 10, 20 may be pins instead of cylinders as shown.
