Abstract

A method for the automatic operation of a centrifugal drier comprising a rotary cylindrical screening basket and which is operated cyclically in successive cycles whose rhythm is a function of the flow of the product to be dried and each of which includes the stages of charging the basket with the product containing a particulate solid material, accelerating the rotary basket for centrifugally separating liquid from the solid mataerial to obtain the solid material in predried form, washing the predried solid material with a washing liquid, maintaining the basket at a constant rotary speed until the solid material has been completely dried, decelerating the rotary basket and discharging the dried solid material from the basket at a low rotary speed, which comprises, at the end of each cycle, the steps of fixing the duration of the stage of completely drying the solid material as a function of the time available for the following cycle to reduce the time interval between two successive cycles to a minimum, and determining the quantity of the washing liquid to be used in the following cycle as a function of the duration of said stage.
