ABSTRACT:
Apparatus and method are provided for treating a fluid mass or stock, particularly couch stock in paper making. Stock material is fed into a vessel having a mixing arrangement comprising rotatably arranged processing means. At lest two processing means are caused to rotate mutually adjacent in opposite direction and essentially horizontally. The stock at the upper surface of the means is conveyed towards a wall portion of the vessel, whereby spirals arranged in an inclined manner at a core of the processing means bring stock into channels defined by the core, by the spirals, and by the wall portion of the vessel, and further towards a constriction formed by the respective spiral elements running in an intermeshed manner, while a part of the stock is forced in a direction away from a discharge of the vessel.
