Dryer system with improved throughput

A dryer system for removing surface moisture from particulate, the dryer system comprising:

• a centrifugal dryer having a particulate lifting cylindrical rotor assembly positioned within a foraminous membrane, the cylindrical rotor assembly comprising a cylindrical rotor assembly having a plurality of lifting blades arranged in horizontal rows, the lifting blades for lifting the particulate through sections of the centrifugal dryer, the particulate generally drying as it is lifted through each section, each lifting blade having a trailing edge, a leading edge, an attached edge, and an outside edge;
• wherein the cylindrical rotor assembly of the centrifugal dryer comprises at least two sections, a wet particulate feed section into which the particulate enters the centrifugal dryer, and a drying section located above the wet particulate feed section, wherein the number of lifting blades per a given length of the wet particulate feed section is less than the number of lifting blades per the same length of the drying section, and wherein the wet particulate feed section comprises two or more horizontal rows of lifting blades, the lifting blades of the two or more horizontal rows progressively spiraling upward around the rotor assembly.
