摘要

Method and device for optimizing the cleaning of lines or systems through which liquid flows along a flushing path. In the method, at the beginning of the purge section at the feed point, a pulsed admission of the at least partially filled with liquid line with a gas or a gas mixture is performed. The method comprises:an initial resting phase in which the flushing path is or becomes filled with liquid,a retraction phase in which the flushing section is partially emptied,a pulse phase in which the flushing path is exposed to a plurality of sequences of at least two pulses with the gas or gas mixture,wherein at the end of a sequence to the beginning of the subsequent next sequence, a pause phase (P) is introduced, in which there is the pressure reduction and partial filling in the flushing path.
