Grain drying is a very power capacious and expensive process. The prices of power resources being used in grain drying increase year by year. The solid or liquid fuel, electric power or the sun energy is usually used for grain drying in order to heat air. In order to reduce the great consumption of power resources and to slash the drying costs, grain drying technologies with small consumption of power should be applied. Using the new, low temperature technologies in grain drying the same effect can be achieved as using high air heating temperature oasts or hot oasts. One of such technologies could be grain layer drying at low air temperature in ozone setting. Carrying out experiments in laboratory, it is apparent that carrying out moisture from grain is more effective if there is the active ventilation with ozonized air. The presence of ozone in the process of the grain active ventilation increases carrying out moisture. Power is educed when ozone decomposes transforming back into oxygen. The laboratory research approved the efficiency of the presence of ozone in the grain active ventilation process.
