Abstract

The delay of deterioration of wet paddy by ventilation with cool air (15+8oC) and ambient air (30±8oC) was determined. Ventilation was applied in two forms, continuously and intermittently. The initial moisture content of paddy was 21.0, 22.2 and 26.0% wet-basis. Air flow rate used was 0.35 m3/min-m3 of paddy. Paddy could be cooled down to 20oC and to near ambient air temperature within one day by cool air and ambient air ventilation, respectively. The quality of paddy could be maintained at an acceptable level more than one month, either by cool air ventilation or ambient air ventilation. The quality of paddy in terms of whiteness was better for paddy ventilated with cool air.
