The invention is a distributed airways airflow dryer system for coffee
beans and other such bulk crops. The interior volume or container of the
dryer or dehydrator system that holds the bulk crops, is filled with an
airways network structure that provides uniformly distributed open wall
airflow passageways in the bulk crops. The airflow passages communicate
with airflow openings in the walls or bottom of the container, to divide
and admit the drying airflow into and through the full volume of the bulk
crops as a large number of individual airstreams. Corrugated, ribbed, or
cross-ribbed airflow plates are preferred embodiments that provide narrow
open grooves or channels that expose the beans or kernels of the bulk crop
directly to the airflow. This results in faster drying and greater
uniformity of the drying effect on the full volume of the bulk crops. The
airflow can be readily reversed through the system to further distribute
the accelerated drying effects of the distributed airflow on the volume of
bulk crops.
