AERATION AND DE-AERATION DURING FILLING WITH VERTICAL IMPELLER
reduction of wall friction in the filling channel via minimized aeration by means of ring gap aeration ring gap aeration prevents, that air is reaching the core of the product amount of aeration is depending on the filling speed

this results in a clean filling process under high filling pressure and thus in a dense packing
