It is considered that there are considerable financial advantages to be gained by drying malting barley in deep silos which can, at the end of the drying season, be used for the continual storage of either barley or malt. A prototype bin ventilated by heated air was designed to give the best possible drying conditions with barley of moisture content up to 23%. Experiments carried out in this bin are described. It is shown that a charge can be safely and evenly dried in three to four days without deterioration of germinative power or loss of maltabihty. Investigations of the most economical airflow and the amount of turning of the grain were also carried out. The thermal efficiency of the system was found to be at least equal to, if not better than, that of other forms of drying plant.
