Noting that it is doubtful whether previously described systems for bulk drying of barley in silos will, under moist weather conditions, give the required reduction in moisture sufficiently quickly to prevent damage, it is now proposed to effect the drying with air previously desiccated by treatment with silica gel. A 600 Qr. silo is described, so constructed as to avoid accumulation of damp pockets of grain. The air used is normally unheated, but heated air is used (90–95° F.) when atmospheric temperature is consistently below 45° F.; the air is distributed through the grain with the help of suitably disposed ducts, cruciforms and fans. Barley can be dried from an initial moisture content of 18–19% to 11–12% in 6 days; the process is economically attractive and does not impair germinative capacity.
