Abstract

The present invention relates to a system (200), and a corresponding method, for controlling the cleaning of a feeder housing (102) in a high-pressure feeder (100) with a housing ( 102) comprising a tapered cylindrical chamber ( 104) for holding a tapered cylindrical pocketed rotor (106). The chamber (104) has a drive end (108) and an opposing tending end (112). The system (200) further comprises a fluid conduit assembly with a first conduit part (1 18a) for transporting a first flow (FI) of cleaning fluid to the chamber (104) via the tending end (112) of the housing (102) and a second conduit part (118b) for transporting a second flow (F2) of cleaning fluid to the chamber (104) via the drive end (108) of the housing (102). The system (200) also comprises a control valve (120) arranged on the first conduit part (118a) for controlling the first flow (F1) and a controller (210) configured to control the control valve (120) to reduce the first flow (F1) in response to a first input signal (SI) indicative of the initiation of a cleaning of the high pressure feeder (100).
