Abstract (en)

Double-flighted thread pulp press screws, for use in horizontal volumetric presses having two parallel horizontal sub-screws (3) introduced inside a longitudinal cage or envelope, commonly used in the sugar industry, wherein the sub-screws (3) have a double-flighted thread (1,2) of equal distance to the filtering cage (4), housed such as to prevent the existence of collision with each other and the use of which provides, combined with the incorporation of a scraping/cleaning edge (5) on the outer end of the threads that form the two sub-screws of the press, a substantial enhancement in the performance of the assembly.
