The aim of this research is to study the variables influencing the mechanical coating of quinoa seeds. These factors are coating speed, temperature and time, and seed lot. The main results in this study can be summarized in the following points, the maximum quinoa-seed germinations of 90.5, 94.3, and 81.4 % by utilizing the covering unit speed of 28 rpm, covering season of 15 minutes, covering temperature of 30 °C, and covering with "Fe + Zn", "Fe + Zn + Cersan" and dirt individually. In the meantime, the base quinoa-seed germinations of 24.6, 35.4, and 22.5 % by utilizing the covering unit speed of 36 rpm, covering season of 60 minutes, covering temperature of 70 °C, and covering with similar constitutions separately, the maximum machine limit of covered quinoa seeds of 9.0 kg/h was acquired utilizing seeds-group mass of 2.5 kg and covering unit speed of 36 rpm. In the meantime, the base machine limit of covered quinoa seeds of 0.85 kg/h was acquired utilizing seeds-group mass of 0.5 kg and covering unit speed of 20 rpm, the maximum and creation costs at ideal boundaries (lot mass of 2.5 kg, covering unit speed of 28 rpm, covering temperature of 30 °C, covering season of 15 minutes, and covering with "Fe + Zn + Cersan") were 14.15 L. E./h and 4238 L.E./ton.
