<p>The invention relates to methods and an arrangement for treating a fluid mass or stock (32), especially couch stock or the like in paper making, where stock material (30) is fed to a vessel (10) having a mixing arrangement comprising rotatably arranged processing means (20). At least two processing means are brought to rotate mutually adjacent in opposite directions and essentially horizontally. The stock (32) at the upper surface of said means (20) is conveyed towards a wall portion (11) of said vessel (10), whereby spirals (24, 24') arranged in an inclined manner at a core (22) of said processing means bring said stock (32) into channels (34, 35) defined by said core (22), by said spirals (24, 24') and by said wall portion (11) of said vessel (10), and further towards a constriction formed by the respective spiral elements (24, 24') running in an intermeshed manner, while a part of said stock is forced in a direction away from a discharge (12) of said vessel (10).</p> |
