Method for clarifying a flowable product with a centrifuge

A method for clarifying a flowable starting product (AP) with a centrifuge, in particular a separator with a feed and at least one liquid discharge for continuously discharging at least one clarified liquid phase - a clear phase - and with discontinuously openable solid-discharge openings for discontinuously discharging the solid phase, is distinguished by the following steps: a. setting or determining a starting time; b. repeatedly determining at least one actual value of a product parameter of the clear phase (KP) derived from the drum; c. determining the time interval until the product-parameter actual value reaches or exceeds a product-parameter limit value; d. preferably initiating a solid discharge as a result of reaching or exceeding the product-parameter limit value; e. ascertaining and setting an operating time interval t(B) by means of the ascertained calibrating time interval t(K), the operating time interval t(B) being less than or greater than the ascertained calibrating time interval t(K); and f. initiating at least one or more solid discharges each time the set operating time interval t(B) has elapsed.
