Steam atmosphere drying exhaust steam recompression system

A heated steam atmosphere dryer system for providing energy efficient drying of matter, comprising;

• a dryer comprising;
• a vessel having an internal chamber,
• inlet means for receiving wet particulate matter and steam into said internal chamber, whereby the steam is a medium for drying said wet particulate matter,
• encasing means for receiving steam externally of said vessel so as to provide indirect heat to said internal chamber,
• means for creating a pressure differential within said vessel, said means for creating a pressure differential comprising a turbulator for generating centrifugal forces within said internal chamber resulting in at least one recirculation path comprised of a mixture of steam and particulate matter,
• a separator comprising;
• means for receiving steam and particulate matter from said internal chamber,
• means for separating said particulate matter from said steam,
• means for permanently withdrawing separated particulate matter away from said system,
• a recompression system comprising;
• compressor means for receiving and compressing said steam from said separator and transporting a first portion of said steam to said encasing means,
• exchanger means for receiving a second portion of said steam from said compressor, for heating and transporting steam to said inlet means,
• whereby energy efficient drying of particulate matter is effected through recirculation of steam through said recompression system.
