Centrifugal drying overcomes those obstacles and speeds production by drying two ways. Centrifugal force from the spinning action of the basket "throws off" excess water, oils, or other liquids. At the same time, a turbine fan mounted below the basket creates a powerful suction that pulls heated air through the parts load for added drying power.
