Abstract

The optimal use of rotary Seed coater needs the knowledge of the physical properties and the behavior of Seed motion in Rotary drum. One of the most important parameters in such equipments is the rotational speed of the drum which causes the rolling action of Seeds. In this research a new method was used for measuring these properties which was based on the motion of Seeds in a less than 50% filled rotating drum. Firstly the Angle of repose of three types of Seed (vetch, wheat and tomato Seed) with different shape was measured with different methods and the values obtained were compared. Then, the lower and upper Angle of repose were also measured by Rotary drum. At the final step, the rotational speed of the drum were gradually increased from 0 to 100 rpm. The speed of the drum which caused the Seeds rolling motion to start and end was also measured. The results showed that the shape of the Seeds had a great impact on the type of motion in the rotating drum and it was obtained that the vetch Seeds had the widest speed range with rolling Mode of motion (from 1 to 65 rpm). However, this range for tomato Seeds is from 8 to 40 rpm and for wheat Seeds from 6 to 49 rpm. Finally the increase of filling degree of frum from 25% to 40%, resulted the rolling Mode of motion for all of Seeds began and end sooner.
