Abstract: This process embodies forcing air through grain and granular biological products using a high volume horizontal airflow from a central vertical pervious tube to one or more plenum chambers near the structure sidewall to dry or cool products. Cross-flow air movement can be supplied by either suction or pressure. This conditioning and drying method has advantages over conventional storage structures, especially where product depth is much greater than diameter. In this process, horizontal air typically moves only ? to ? of vertical distances. Horizontal airflow resistance through elongated seeds is 50-60 percent of vertical airflow. Power for horizontal airflow is typically 8-15% that of vertical airflow. Grain and seed drying costs will be 15-30% of high temperature drying. To enhance germination, storage and grain and seed quality, and to kill or exclude insect pests, ozone is applied to drying or aeration airstreams for treating stored products and storages.
