The article presents an analysis of previous research on the use of ozone to intensify the active ventilation of grain. It shows the results of two year experiments revealing possibilities of using ozone in active ventilation of grain in 20 m**3 tanks under farm conditions. The essence of the experiments: two equal tanks are loaded with the same amount of grain of the same humidity and are ventilated with the same intensity of air flow by adding generator produced ozone with a concentration of 28 mg•mE−3 to the ventilated air of one tank. The sensor system, installed in the tanks, performs real-time monitoring and records the parameters of the drying process, which are also periodically checked with hand tools. A decrease in the grain moisture in the ozone tank was established during the experiments in contrast to the tank without ozone additive in the ventilation air, especially in the lower layers of the tank. It was found that the ozone additive of the concentration mentioned can be rationally applied in the treatment of 1.5–2.0 m high grain layer at the ventilation parameters indicated in the article.
