Determination of Performance Characteristics of Horizontal Wind Tunnel in the Cleaning of Corn-Cob Mix

Abstract

In the cleaning process, different relative velocities of the grains through the air stream are utilized. The purpose of this study is to determine parameters such as fan angle, material feed rate and air velocity which will ensure separation of corn. Cleaning efficiency increased with increasing fan angle and air velocity and decreased with increasing feed rate. Loss rate increased with increasing fan angle and air velocity, and decreased with increasing feed rate. It can be said that the most appropriate combination (89.79% cleaning efficiency and 0.24% loss rate) was the application at 30° fan angle, 1152 kgh-1 feed rate and 15 ms-1 air velocity.
