Abstract
The main goal of this research work was to an attempt to provide a rational basis for the artificial drying system, in which forced heated air at constant temperature and relative humidity may be used to remove the excess moisture from canola pods (var. serw 10) and to study the effect of both air temperature and relative humidity on the drying process of canola pods and on the quality of the extracted oil from seeds after drying process. This work also aim to test and evaluate six different empirical drying models for describing the drying behavior of canola pods in thin layer. To execute this objective, a controlled temperature and relative humidity laboratory dryer at the Agricultural Engineering Department, Faculty of Agriculture, Mansoura University was used for drying experiments.
The laboratory experiments were conducted at six different levels of drying air temperature (45, 50, 55, 60, 65 and 70oC), four levels of air relative humidity (30, 40, 50 and 60%) and the air velocity was held constant at 2.5 m/sec. A 72 runs was conducted to cover all the possible combinations of drying air temperature and relative humidity. The obtained data was recorded and analyzed. The obtained results revealed that, the reduction in canola pods moisture content was varied and increased with the increase of drying air temperature while it was decreased with the increase of air relative humidity, no constant drying rate period was detected for all studied levels of drying air temperature and relative humidity while all the drying process occurred at a falling rate, the final moisture content of canola pods was decreased with increasing of drying air temperature while it was increased with the increase of air relative humidity, all the drying constants of the six models affected by the drying air temperature and relative humidity and The studied range of air temperature and relative humidity showed no effect on the safe percentage of FFA% in canola oil and it was relatively decreased with the increase of drying temperature.
The results showed that, All the studied models could describe the drying behavior of canola pods and the Two Term model found to be the most proper model in describing the drying behavior of canola pods.
