<p>The invention relates to a spray drying system (1) comprising a spray dryer with a drying chamber (2) and a process air/gas supply device, at least one powder recovery unit (4), a conveying line (11) for powdery material such as fines from the powder recovery unit, a connection assembly (1O) connecting the powder recovery unit or the conveying line to a cleaning-in-place, CIP, arrangement including a CIP line configured to transport CIP liquid. The connection assembly (1O) comprises a sanitary valve (20) including a first inlet (12) to the conveying line or the powder recovery unit , and a valve member (21) moveable between an open position and a closed position, wherein in the closed position, one part of the valve member (21) seals the conveying line (11) and when in the open position, the valve member (21) is moved to provide communication between the CIP line (15) and the conveying line (11) or the powder recovery unit (4), thereby allowing CIP liquid to enter and exit the sanitary valve (20) through the CIP line (15) and into the conveying line (11) or the powder recovery unit (4) via said first inlet (12). In another aspect of the invention, a method for cleaning a spray drying system is described.</p> |
