<p>The method involves recycling a rinsing liquid from a collecting pot (3) to spraying devices (4, 5) via conduit systems (8,9). Modulation of volume flow rate takes place through the spraying devices during cleaning section through periodic connection and disconnection of fluid supply. Frequency of modulation lies within a range of natural frequency of the conduit systems, where the frequency lies between two and five hertz.</p> |
