dc.description.abstractThe article presents an analysis of the previous research on the use of ozone for intensified active ventilation of grain and develops a methodology for experiments to evaluate the usefulness of ozone utilisation in ventilation in farm conditions. The essence of the experiments: two identical 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 to the ventilation air of one tank ozone, produced by the generator. The sensor systems installed in the tanks record the drying process parameters. The sensor systems, developed and installed in the tanks, worked without fail, providing a possibility to follow the ventilation modes in the computer, both on the farm, and remotely. During the experiments a small reduction in the moisture content of the grain in the ozone tank was consistently observed in several aspects, as compared to the tank without the ozone admixture to the ventilation air, yet the advantages of the method have not been convincingly proved. Therefore, experiments should be continued in 2020 during grain harvesting by ventilation in both tanks for grain, 3.0-3.5 m high. It has been proved during the experiments that, using active ventilation, we can prepare extra quality food grain for sale, reducing the humidity by 7.0-8.0 %.en_US
