Ventilation or aeration of grain bulks with ambient air at flow rates of 0.5-1.0 m3 min-1 ton-1 cools the grain to a uniform temperature (4). Moisture migration is reduced because the temperature gradients are lower in aerated grain bulks. By lowering the grain temperature and reducing moisture accumulation, aeration decreases the probability of the occurrence in the grain bulk of niches suitable for the growth of grain storage pests. Ventilation of grain bulks with ambient air or slightly heated air at flow rates of 1.0-2.0 m min-1 ton-1 can be used to dry grain (9). Low-temperature drying has a number of advantages over high-temperature drying:a (a) equipment is less costly (b) energy requirements are lower and
