Apparatus for bulk drying of sliced and granular materials

A dryer system for drying materials of uniform thickness, comprising:

• a materials container for holding said materials for drying,
• a high pressure plenum communicating with a first ventilated surface of said container,
• a low pressure plenum communicating with an opposing ventilated surface of said container;
• a plurality of parallel and uniformly spaced corrugated airflow plates disposed within said container so as to define bays of at least said uniform thickness, said airflow plates configured with open wall airflow channels connecting said inlet plenum to said outlet plenum,
• a primary airflow circuit comprising a connecting airway running from said low pressure plenum to said high pressure plenum and hence through said container and into said low pressure plenum,
• a primary airflow sustainable by a fan,
• a solar permeable enclosure for heating said primary airflow,
• means for removing moisture from said primary airflow.

A dryer system for drying sliced materials of uniform thickness comprising:

• a container for holding said sliced materials for drying,
• an inlet plenum communicating with a first ventilated surface of said container,
• an outlet plenum communicating with an opposing ventilated surface of said container,
• a plurality of parallel and uniformly spaced airflow plates disposed within said container so as to define a parallel set of bays of uniform thickness, said airflow plates configured with open wall airflow channels connecting said inlet plenum to said outlet plenum,
• means for exerting a pressure differential between said inlet plenum and said outlet plenum so as to maintain an airflow through said container.
