In tanks (2) consisting of two upright, mutually intersecting, circular cylindrical tank sections, each having a concentrically operating stirring system (6,8), the bottom portions (18,20) are shaped such that they are sloping to form respective concentric bottom grooves with downwardly pointed cross section, the lowermost portions (22) of which meet or overlap each other midway between the two shafts (6). Hereby is formed a lowermost groove system (22) shaped as the figure of eight and from which an effective emptying can be achieved through a single outlet (26). <IMAGE> |
