Method for separating solid and liquid phases

A method for controlling separation of solid and liquid phases in a centrifugal basket of a centrifugal, the method comprising the steps of:

• determining self-induced vibrations of the centrifugal within a predetermined rotational speed range of the centrifugal basket using an accelerometer,
• monitoring at least associated values of the rotational speed of the centrifugal basket and a purging of the liquid phase from the centrifugal basket,
• wherein the purging of the liquid phase from the centrifugal basket is monitored using the accelerometer, and
• wherein the purging of the liquid phase from the centrifugal basket is monitored while taking into account the determined self-induced vibrations of the centrifugal,
• determining a safe temporal range within which temporal range a washing liquid or steam can be safely applied to the content of the centrifugal basket, and
• applying a washing liquid or steam to the content of the centrifugal basket during at least a portion of the safe temporal range.
