Definitions
- annular partition 21 is arranged perpendicular to the axis of the filter and carried by the rotor 5.
- the flow of dough is deflected by the annular partition 21 and strikes the partitions 20 which are linked to the sieve and crosses the cavities C to return to the space 6.
- Figure 6 combines the provisions of Figures 1 and 2.
- the annular rings 41, 42 and 43 define four zones of the rotor 40.
- FIG. 15 illustrates another alternative embodiment in which the same elements have the same references.
- a pipe 50 which is a water pipe.
- the filtration element according to the invention can comprise, from top to bottom:
- the filter element constituted by the screen 30 and the rotor 40 is thus divided into three zones X, Y and Z starting from the bottom.
- the speed of the rotor 40 can be adjusted as a function of the pressure differential between the inlet Q into the apparatus and at least one of the pressures prevailing in the outlet conduits for the accepted products 60, 61, 62. It is also possible to adjust the speed of the rotor 40 as a function of one or more of the flow rates in the pipes 60, 61 or 62.
