Última Evaluation of Mechanical Z-Type Elevator Operation for Handling Seed Corn CIGR Journal Gazor, Hamid Reza; Roustapour, Omid Reza. Handling systems in seed processing factories inflict impressive damages on seed corn. It was reported 24% of damages on seed corns related to elevators. In current research, the operation of a Z- Shape elevator was studied and compared to conventional bucket elevator which employed in two seed drying stations of Seed and Plant Improvement Institute in Karaj city and Shahi plant in Moghan plain, Iran. The effect of elevator operation on seed cracking and breakage was determined by t- test. According to the results, applying Z- Shape elevator decreased the physical seed damages up to 78% and reduced the chance of seed cracking between 4 to 8% in comparison with conventional elevators. Economically results illustrated spending the cost equal to 10% of the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Conveying system; Corn; Loss; Seed; Z- Shape elevator. Ano: 2021 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/6689 Comparison of conventional tractors performance during primary tillage in Iran CIGR Journal Safari, Mahmood; Gazor, Hamid Reza. Primary tillage parameters and their effects on tractor efficiency, fuel consumption management and cost reduction are very important in mechanization.  The main goal of this study was to determine some performance parameters in three conventional tractors Massey Ferguson 285(MF 285), Universal 650 (U650) and John Deer 3140 (JD3140) to primary tillage practices in some area of Iran.  These parameters are important for selecting tractors to set up mechanization program in a large scale.  The sampling method was random in 10 regions with seven replications.  After data gathering, results were analyzed using SPSS software.  Results indicated that average drawbar power for plowing without considering of area and tractor type was 15 kW.  The maximum and minimum...
