Abstract
The effects of different fan-control strategies and the type of hourly weather data on the drying-parameter profiles for rapeseed having a moisture content of 18% (d.b.) using computer simulations have been investigated. The airflow rate of 540 m 3/hm 2 was employed using the hourly and average hourly weather data of the period after harvesting on 25 February 1971. The duration and the width of the drying front, using the strategy of fan-on when RH ≤ 70%, were both observed to be smaller as compared with the strategy of continuous fan operation, indicating that the drying front passes faster through the grain bed. The total drying time was increased using the strategy of fan-on when RH ≤ 70%. It was shown that the average hourly data could successfully be used if the real hourly data were not available for the simulation.
