Said process (10) particularly comprises a first phase (Phase A) of start, a second phase (Phase B) of sampling by multiple short and long detections, a third phase (Phase C) of processing by compensation calculation and a fourth phase (Phase D) of self-adjustment, said second, third and fourth phases (Phases B-D) being totally automatic, that is to say, being sequentially carried out by the electronic grinder-doser apparatus (20) as automatic procedures by the logic control unit (203). 33Ta PI Ek Em I0 0,25 050,75 T On TPlbP Fig. 2
