Abstract
Abstract Grain treatment apparatus has a plurality of air boxes arranged one above the other in a column, each box having a perforated upper, horizontal surface constituting a tray. An air circuit includes a manifold for receiving air from spaces between the boxes and leading to an air-grain separator and a source of heat. Grain is fed to the uppermost tray, travels thereover and descends in a zigzag, series path over the other trays to a valve releasing the treated grain at a predetermined rate. There are walls and curtains and weirs within the column to define the air and grain passages.
