Abstract
             This study was conducted in order to develop a simple local device for separating small seeds and aimed to utilize the use of centrifugal force in separating seeds for minimizing the costs and losses of separating small seeds. The studied factors were three disc positions of (P1=20, P2=15 and P3=10 rubber spikes fixed on its upper surface), three cylinder positions (a= without any spike, b= 7spikes in one row and c= 14 spikes in two rows fixed on its inner surface), four disc speeds of (S1= 3.9, S2= 5.7, S3= 8.2 and S4= 10.4 m/s), three levels of seed moisture content           ( M1=19.8, M2= 15.2and M3= 10.3 %) and four levels of separating clearances            ( C1=1.0, C2=1.5, C3= 2.0 and C4=2.5 cm). The evaluation was on the following parameters:- seed quality, separating efficiency and capacity. The suitable conditions for using the new prototype device were ( position P1 )=20 spikes on separating disc ,(position C ) = 14 spikes on cylinder, 5.7 m/s disc speed, 1.5 cm of separating clearance and 15.2% of seed moisture content. The previous factors gives 99.31 % of seed quality, 89.19 % of germination ratio, 99.34% of separating efficiency and 5.87 Kg/h  of separating  seed capacity .
