A method for the automatic operation of a centrifugal drier comprising a rotary screening basket having a cylindrical wall and which is operated cyclically in successive cycles, each cycle comprising the steps of rotating the basket to generate a centrifugal force, charging a product to be dried into the rotating basket through an open valve, the centrifugal force causing the product to form a layer of increasing thickness along the cylindrical wall, closing the valve to discontinue charging the product when the layer thickness has attained a first control value lower than that of the layer thickness corresponding to an imposed value of the charge in the basket, then measuring the maximum thickness of the layer, comparing said measured maximum layer thickness with a second control value corresponding to said imposed value of the charge in the basket, and generating a new value for the first control value as a function of the difference between the measured maximum layer thickness and the second control value.
