Establishing time for the drying of corn by using dryer tehnology

Abstract

In the paper presented investigation of establishing time of drying of corn by using dryer technology or to drying the corn of different ripening groups (groups from 400 to 600) with increased moisture at the exit of the dryer for corn with the 19.47 % on storage moisture and increased temperature of corn grains at 35.5 °C. The aim of this study was to determine the time needed for corn grain drying using dryer technology after leaving the drier. This technology is based on cooling corn grain after drying it, but not in the cooling zone in the kiln, but in separate cells for conditioning. Tests show that the grain in the cells age from 7 to 10 hours and during that time it is ,,sweated" in order to be cooled by the external by blowing air through the fan after sweating. Moisture from the grain surface is removed by the air and grain is dried to the level of the storage moisture. Total of 149.797 kg of corn graine of average humidity of 33.85 % was dried. Time of ventilation lasted 50 hours while the time of conditioning lasted 27.10 hours.
