The paper analyzes alfalfa seed cleaning using a magnetic separator, and the influence of the dodder seed amount on the cleaned seed amount. Seed cleaning was performed at the Institute of Field and Vegetable Crops in Novi Sad and three alfalfa seed lots were cleaned after passing through the primary cleaning process (selector, gravity table and roll mill). After cleaning, the quantity of pure seed (kg), waste (kg) and the time used for cleaning (h) was measured. The input quantity of all three seed lots was 1000 kg, whereas the waste ranged from 7.8 to 9.8 kg after cleaning. The purpose of this study is to monitor the operation of a magnetic separator in order to determine the amount of waste after cleaning. On the basis of the results obtained, an insight into the influence of the dodder seed amount on the cleaning rate and the required number of cleaning repetitions was obtained.
