Abstract:
A method for treating a fluid mass comprising feeding a mass material to a vessel or trough having a mixing device;said mixing device comprising rotatably arranged processing means; wherein at least two of said processing means are caused to rotate in opposite directions and substantially horizontally adjacent to one another; the method further comprising conveying the mass at the upper surface of the means out towards the respective opposite portions of the vessel or the trough, wherein the opposite portions are delimited in the radial direction of the processing means; bringing the mass, using a plurality of spiral elements arranged in an inclined manner at a substantially cylindrical core of each respective processing means, into horizontal channels arranged in an inclined manner; which channels are defined the core, by opposite wall portions of respectively two adjacent spiral elements, and by wall portions of the vessel which are adjacent to the spiral elements; and bringing the mass towards a constriction formed by intermeshed spiral elements arranged, respectively, at each two of said processing means rotating in opposite directions while disposed adjacent to each other.
