<p>A plant for the aerobic biological transformation of organic waste materials, in which the stirring screws which control the agitation and the forward movement of the material being treated are immersed in the biomass, and thus operate actively, when moving in the direction opposite the movement of said material, while, in the opposite course, i.e., in the direction which is concurrent with the movement of the material, they are extracted from the biomass, with the axis of the stirring screws being inclined at an appropriate angle, which is preferably between 10 and 60 degrees, with respect to the vertical, with the material being moved towards the unloading area by the displacement in the loading area of the screws, which are inclined and rotating in the raising direction of the biomass. In addition, the screws vary this angle, inceasing with respect to the vertical, by gradually moving from the material unloading side on the reservoir towards the loading side, while the distance of said screws from the bottom remains constant.</p> |
