Abstract Corn is considered as one of the most important food crops in Egypt and the world. It is used for human coiisun~ption and animal feed and it can be stored for long periods of time and transported in bulk over long distances. Usually corn is harvested at high moisture content levels than that fitted to dry niilling and storage and to clear tlie land early enough for tlie next crop cultivation and to avoid the heavy scattering loss. This investigated deals with the post harvest process, i.e., drying, which is believed to play a vital part in the beuer management of the grain production. Drying is one of the processes necessary to cut down losses and prevent grain deterioration after early harvesting. Resistance to airflow is an important factor in the design and the performance of the drying system. The need for drying has made it necessary to obtain information on the resistance to airflow. The presented experiments were mainly carried out to show the effect of variables such as the temperature, airflow rate, moisture content, and the metliod of airflow (forcing - suction) on the airflow resistance characteristics inside shelled corn bulks. Also, to Itnow tlie behavior of drying process (drying time and corn quality) for both suction and forcing air method. The main aim of the present study is to investigate the behavior of airflow method (forced - suction) which heated by electrical healer and their affected on resistance of airflow. |
