This study aims at developing a highly efficient agricultural product dryer by ensuring uniform flow distribution in the drying room. A theoretical simulation was conducted to analyze the effect of element parts to control the flow in the dryer room. At first, the flow mechanism in the drying room of the existing dryer having four vertical branch ducts is investigated. Secondly, the effect of installing ribs, porous plates and change in the size of air-vent and inflow guides are analyzed. Uniform flow has been accomplished in the drying room with a 14 degrees rib and porous plates. An air-vent ratio of 1:2:3 in vertical branch ducts and the presence of inflow guides in the main ducts can produce a uniform flow in the dryer room.
