Development of optimal management schemes for in-bin drying of canola grain (rapeseed)

Economic analysis of low-temperature grain drying

“…During simulations, airflow rate was 2.0 m 3 min -1 t -1 , while relative humidity and temperature of drying air were equal to 70% and 40°C, respectively. These values followed the recommended ranges of drying temperature (30 -40°C), relative humidity (65 -70%) and airflow rate (1.5 -2.0 m 3 min -1 t -1 ), which were previously tested for low-temperature grain drying and were proved to be efficient for maintaining the product quality, also reaching the drying effects within an appropriate time and without requiring excessive energy consumption (Arinse et al, 1993;Tirawanichakul et al, 2004). Initial grain moisture contents of 20% (wet basis) were used during simulations, which were performed in such way that product was dried until equilibrium moisture content was achieved.…”

Criteria of Determination of Safe Grain Storage Time – A Review

“…Sometimes, however, mathematical formulas are more useful. They can be easily incorporated into the mathematical models of grain drying or aeration and expert systems which are aids for storage-grain management (Arinze et al, 1993;Courtois, 1995;Fleurat-Lessard, 2002; Kaleta, 1996). Such formulas known in the bibliography of the subject and own formulas developed by the authors of the chapter are presented in the paper.…”
