Sunflower Hulls Pellet Mill&Utilizing Sunflower Hulls as Solid Biofuel: Revolutionizing Energy Efficiency in Oil Mills


sunflower-hull-pelletUtilizing Sunflower Hulls as Solid Biofuel: Revolutionizing Energy Efficiency in Oil Mills

Sunflower hulls, derived from sunflower seed de-hulling before oil extraction, present an untapped resource for powering sunflower oil mills. Traditionally, these hulls, light and low in density, weren’t ideal for direct burning in boilers or stoves. However, the innovation of the sunflower hull pellet machine has transformed this by-product into a potent biofuel source, reducing energy costs for oil mills worldwide.

The Sunflower Hull Pellet Machine:
This machine efficiently processes sunflower hulls into pellets without requiring prior drying. Additionally, by mixing the relatively low heating value of rice husks with sawdust before pelletizing, the calorific value of the pellets can be significantly enhanced. The compact and environmentally friendly rice husk pellet mill, operable via electric motor or diesel engine, stands out due to its mobility, low maintenance, and minimal investment, making it ideal for on-site solid fuel production at sunflower oil mills.

Benefits of Sunflower Hull Pellets as Solid Biofuel for Oil Mills:
Produced as dark brown cylindrical pellets of 6-8mm diameter, sunflower hull pellets offer high calorific value and efficient energy utilization. With a calorific capacity 1.6 times higher than wood pellets and comparable to coal, burning 1000 kg of sunflower hull pellets generates energy equivalent to burning 685 liters of furnace oil, 500 liters of diesel oil, 479 cu m of natural gas, or 1600 kg of wood pellets. Moreover, they contribute negligibly to global warming.
