PROCESSING APPARATUS

摘要

Flowable material is mixed and forwarded through a processing apparatus by means of a rotating structure having an array of annular discoidal members coaxially mounted thereon to rotate therewith. The annular discoidal members are inclined away from normality ot the axis of rotation, and the most rearward points of the peripheries of the successive discs are disposed along a helicoidal line coaxial with the rotation of the structure, which disposition of the discs causes the structure as a whole to emulate the action of a screw in that the flowable material is propelled through the apparatus. When the depth of flowable material in the apparatus is regulated such that it approximately equals the annular width of the discs, veils of flowable material continually fall from the rotating discs, for example to promote chemical reactions.
