his paper presents the performance analysis of rotary cottonseed dryer. Experiments were performed on cottonseeds, at inlet air temperatures of 100, 110, 120°C, and drying air mass flow rates of 0.00563, 0.0064, 0.00709 kg/s by using two different flights. The performance of dryer was evaluated by checking effect of operating variable on weight loss of dried products, specific energy consumption (SEC) and pick-up efficiency. Image analysis method was used for determining design loading of drum. Weight loss of cottonseeds was found to be in the range of 0.446-0.788 kg. The pick-up efficiency and SEC varied between range of 7.19-19.52% and 0.219-0.399 kW-h/kg respectively.
