Abstract: Excerpts from the report: Several methods of drying rice are available to farmers, but most of the combine-harvested rice is custom-dried in continuous -flow, heated-air dryers. Such a dryer usually consists of a tall, vertical column through which rice flows by gravity. Heated air is forced through 4- to 6- inch layers of rice as the rice moves slowly downward. Some dryers are designed so that rice is continually agitated as it flows downward, while in other makes, there is no attempt to divert the rice from a straight path. The temperature to which the air is heated and the speed at which rice flows through the dryer can be varied on most makes of dryers. An experimental rice dryer, similar to commercial dryers except for its smaller size and lower drying capacity, was built by the U. S. Department of Agriculture at the Rice-Pasture Experiment Station, Beaumont, Tex. Studies are being made with this dryer to establish better methods of drying and to explore the uses of aeration as a supplemental treatment for drying rice in heated-air, continuous-flow dryers.
