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.

Tyrimų tikslas – laboratorinėmis sąlygomis eksperimentiškai nustatyti džiovinimo vainikinio išlydžio elektriniame lauke efektyvumą ir palyginti jį su džiovinimu elektromechaniniu ventiliatoriumi. Darbe aptariami kviečių ir gražgarstės lapų džiovinimo vainikinio išlydžio lauku eksperimentinio tyrimo rezultatai naudojant elektrodų sistemą „lygiagrečių laidų tinklelis virš įžemintos plokštumos“. Darbe apžvelgtos technologijos pagrįstos vainikinio išlydžio lauko naudojimu Tyrimai atlikti Kauno technologijos universitete elektromagnetinių laukų įtaisų mokslinėje laboratorijoje, su įtaisu kurį sudaro aukštos įtampos šaltinis ir elektrodų sistema „lygiagrečių laidų tinklelis virš įžemintos plokštumos“. Atliktas joninio ir elektromechaninio ventiliatoriaus oro srautų palyginimas. / The aim of the research is to establish experimentally the effectiveness of drying affected by the corona field in comparison with the effectiveness of drying affected by the external airflow driven by electromechanical ventilator. Review of various techniques applying of corona field is given. Results of wheat drying by using the corona field of electrode system „ a set of parallel wires under the grounded plate“ are presented and discussed. Experimental study of drying is performed in Research laboratory of electromagnetic field devices of Kaunas university of technology. Test drying device consists of the high voltage source and the electrode system „a set of parallel wires under the grounded plate“. Comparison of corona field airflow and electromechanical ventilator airflow is given.
