Abstract: Ankstesniuose darbuose nustatant grūdų džiovinimui aktyviąja ventiliacija lyginamąjį debitą neįvertinta savaiminga grūdų šilimo įtaka džiūvimo procesui. Darbo tikslas nustatyti biologinės šilumos įtaką grūdų džiūvimo procesui ir tuo pačiu oro lyginamajam debitui
In previous papers it wasn`t evaluated the influence of grain heating upon drying process, in establishing the comparative disharge while drying by active ventilation. The purpose of this paper to establish the influence of biological heat upon grain drying process and comparative disharge. The influence of heat while drying by active ventilation is low. Therefore this influence upon drying process could de deniable. While deriving the comparative disharge of blowing through grain air according permissible grain keeping term 0,30 kg/kg moisture grain chould be dried 750 m³(t·h) by comparative disharge, 0,266 kg/kg moisture - 450 m³(t·h) and 0,25 kg/kg moisture - 280m³(t·h) by comparative disharge. Using average pressure (Pmax≈Pa) ventilator it would be rational to dry 0,25-0,30 kg/kg moisture grain. Drying lower then 0,25 kg/kg moisture grain, ventilator is used inefficiently
