Abstract: Water hyacinth has small bulk density and high water content, which is not conducive to resource utilization. This study developed a water hyacinth compression-packing machine based on the principle of hydraulic packing, determined the main structural parameters of compressing device, discharging device, etc. other parts, and completed the hardware construction and software programming of the control system. In order to explore the impact of machine operating parameters on compressive packing process performance, this paper took feeding rate, mincing degree, dwell time as experimental factors and bale density, yield and water content as targets, and determined the optimal combination of technological parameters through single-factor and orthogonal experiments by comprehensive scoring method. The results showed that the excellent water hyacinth compressing-packing process performance was obtained when feeding weight was 7±0.1 kg, mincing degree was 6.75±2.25, dwell time was 10 s, and packing density was 446.6 kg/m3, yield was 238.8 kg/h, water content was 91.27%, and comprehensive score reached 0.941. The above results provided references for designing water hyacinth compressing-packing machine with optimized technological parameters.
