Abstract:
When using a straw collector to transport straw, there is a possibility of the mixing of gravel and other particles on the ground with the straw, which ultimately reduces the quality of the harvested straw. To address this challenge, a laboratory cyclone was constructed and evaluated. The study was conducted using a factorial experiment in a completely randomized design. The experiments were performed at three levels of the cyclone inlet opening (1, 0.6, and 0.3), two heights of the vortex finder (0 and 15 cm), and two frequencies of the suction impeller (45 and 50 Hz), with four gravel-to-straw ratios (3.5%, 5%, 10%, and 15%). A total of 144 tests were obtained by performing three repetitions. The results showed that the highest separation efficiency occurred for the inlet opening at 0.6 and 1, respectively. The highest separation efficiency occurred at a suction impeller frequency of 50 Hz and a vortex finder position of zero. The constructed cyclone achieved the best performance for gravel separation at gravel-to-straw ratios of 10% and 15% in the inlet opening level of 0.6, vortex finder position at zero, and a suction impeller frequency of 50 Hz. Additionally, the highest straw separation efficiency was achieved for the inlet opening level with a value of 1 and 0.6, vortex finder at zero and 15 cm, and a suction impeller frequency of 50 Hz at gravel-to-straw ratios of 3.5%, 5%, and 15%. Overall, the cyclone performance was maximum for gravel and straw ratios of 3.5% and 5%, respectively.
