Grūdų džiovinimo aktyviąja ventiliacija procesų modeliavimas

The active ventilation of grain with the optimum drying regimen was the main issue of the work. The moisture of the harvested grain in Lithuania often exceeds the conditional one. Thus the grain should by dried before the storage. The active ventilation is mostly used in Lithuania to dry the grain, it was the topical point in this work. There was analyzed meteorology of the topical months, were maked the calculating equations, whitch we can prognosticate these meteorological facts: temperature and relative humidity. The maked mathematical model defines metathesis moisture‘s between ambient air flow and grain. Also there were the algorithm of model‘s realisation‘s and the computer programme with Visual basic 6.0 maked. Adequacy of mathematical model‘s was rated with results of experimental researches and calculated results.
