Abstract: Sunflower has a vast planting area in the north, and its straw fiber has high strength and good oiliness, which is suitable for making solid fuel．In order to improve fuel molding effect and reduce fuel loss rate during storage and transportation, the Taguchi method was used to optimize molding process parameters and improve fuel quality．Storage environment was simulated to study effect of storage humidity on surface morphology, density, total moisture and wear rate of fuel, and storage conditions were determined．The LBT-5024 vibration table was used to simulate transportation vibration, and influence of fuel packaging material and transportation vibration frequency on quality defect of sunflower straw solid fuel after vibration was studied, and optimal packaging material and reasonable vibration frequency were determined．Results showed that, contribution rate of sunflower straw solid fuel molding process parameters to density was moisture content 59.26%, temperature 1.59%, pressure 32.96% and particle size 0.59%, optimal process combination was moisture content 9%, temperature 110 °C, pressure 120 MPa, particle size 0.16−0.63 mm．In order to ensure that physical quality of solid fuel could meet requirements for use, storage humidity should be lower than 60%RH, and choice of packaging materials was iron box > wooden box > snakeskin bag > carton．Vibration frequency was controlled at about 2 Hz．
