Abstract (en)
[origin: WO2018073053A1] In order to remove dust, in particular the dust (11) adhering to the granulate grains (4), from the granulate (4), the granulate grains (4) are moved upwards out of the granulate collection on the base of the granulate intermediate container (9) via a preferably laminar air flow (32), in order to preferably prevent friction of the granulate grains (4) against one another, and to prevent the associated formation of new dust (11), until, under the influence of gravity, the granulate grains (4) drop back down laterally outside of the air flow (32) and fall back into the granulate collection (4). Simultaneously, a vacuum is applied above this air flow (32), in order to suction upwards the dust being removed from the granulate grains (4). Both together can be achieved by applying an, in particular controlled, vacuum at the air outlet opening (18) for the dust-laden air. In order to facilitate the removal of the dust (11) from the granulate grains (4), the air of the air flow (32) is ionised during or before reaching the granulate collection (4).
