Claim 12:
13. A method for removing dust from a granulate (4) by means of a device according to claim 1 whereby the dust (11) adhering to the granulate grains (4) is to be removed, and wherein for batchwise operation
with or without counterflow (32), granulate (4) is filled into the dedusting container (9) up to a predetermined filling level,
the filling process is terminated when the filling level is reached,
the dedusting of the filled batch (4′) in the dedusting container (9) is carried out by means of introduced ionized air, and whirling up the granule grains (4) by means of a counterflow (32) and conveying out, dust-laden gas,
the dedusting container (9) is cleaned by flushing with an ionised gas, in particular ionised air,
after the filling level has fallen below the specified level, the previous steps can be carried out again.
