Abstract Rice is the most important food crop for more than one-half of the world’s population. In Egypt, it is not only a stable food but also a major source of livelihood. The crop is usually harvest at September and October each year at relatively high level of moisture content (20-25% wet basis) to minimize field losses and maximize the quality of milled rice as well as to allow for the timely preparation of the land for multicroping .The majority of rice crop harvesting process has been mechanized by the use of combine harvesters, which enables large quantities of high moisture grains to be harvested in a short period of time. The main reason for extended the period of harvesting the crop in Egypt is the lack in the efficient drying systems having high capacities to accomplish the drying to coincide with the high rate of mechanical harvesting. A real solution to avoid the expected losses is to harvest the crop in the proper period and store the high-moisture grain in bins and dried it by using the natural air under local weather conditions. The; present study were conducted to investigate and evaluate the utilization of natural air for drying and aeration the high-moisture rough rice stored in bins under local weather conditions. |
