Dairy manure waste fiber to energy process

A system for converting waste fibers to solid fuel, the system comprising:

• a centrifuge configured to receive a mixture of animal waste and water and provide dewatered fibers;
• a drum roller configured to receive the dewatered fibers from the centrifuge and to provide shredded fibers;
• a screw press connected downstream of the drum roller, and configured to receive the shredded fibers and to provide a reduced water content shredded fibers;
• a briquetting device downstream of the screw press, and configured to provide at least one compressed fiber briquette;
• and
• a torrefaction reactor having a re-sealable lid and configured to receive the at least one compressed fiber briquette and provide at least one solid fuel briquette, wherein the torrefaction reactor is heated by an external heat source;
• wherein the external heat source is disposed below the torrefaction reactor;
• and,
• wherein the torrefaction reactor is a double walled reactor;
• and,
• wherein a plurality of absorbent particles is disposed within the torrefaction reactor.
