Abstract
A centrifugal pellet dryer apparatus, lifter and rotor wherein the lifters can have a surface configured to deflect pellets inwardly and the rotor can have lifters attached in an arrangement designed to increase pellet impacts with lifters by providing a higher concentration of lifters on the rotor in a first region which initially engages a slurry of pellets and water. The inwardly curved lifters tend to direct the pellets inwards toward other lifters and away from dewatering screens and the higher concentration of lifters on the lower region of the rotor results in added pellet impacts with lifters. The centrifugal pellet dryer can have an outer housing, a base portion with a water discharge outlet and a top portion having a pellet discharge port and an exhaust port. Within the housing can be one or more generally cylindrical foraminous members disposed around the rotor. One or more separator plates can be provided between the foraminous members to divide the pellet dryer into sections. The rotor with lifters affixed rotates within the foraminous members to direct pellets upwardly to the pellet discharge port which can have a counter-flow air inlet.
