In order to obtain basic data n the drying characteristics of high moisture content wheat by deep-bed dryers such as "Dry Store", experiments were performed under the following conditions: initial moisture content - 25 and 30% W.B.; drying air temperature - 25, 30 and 35 degrees C.: airflow rate - 0.5, 0.8 and 1.0 cubic meter/sec.t; bed depth - 30, 50, 70, 100 and 140cm. The following results were obtained: 1) Average moisture content decreased by the same ratio from the initial moisture content to 18% W.B.. It can therefore, be calculated from the drying time by using a regression line equation. 2) The maximum value of moisture content difference and the time required to reach to the maximum value were affected by the initial wheat moisture content, drying air temperature and airflow rate. They can be calculated from those factors by suing multiple regression curve equations. 3) Static pressure loss in drying constantly increased as the wheat moisture content decreased
