π₯ Boosting Rice Husk Pellet Efficiency with Mix-Match Biomass Strategy in Gujarat & Beyond
π¬ Rice Husk Pellet Sample Report (Gujarat)
Ash Content: 20.85%
Gross Calorific Value (GCV): 3285 kcal/kg
β‘οΈ These results show that while rice husk is abundant, it presents challenges due to high ash and moderate energy yield. To enhance performance, a mix-match recipe combining low-ash and high-GCV biomass materials is essential.
πΎ Objective: Improve Pellet Quality Using Mix-Match Recipe
β Goal: Lower ash content and increase the energy value (GCV) of rice husk-based pellets
β Method: Combine rice husk with selected low-ash, high-energy biomass materials tailored to regional availability

π Technical Considerations for Optimal Pellet Quality
Pellet Die Size: Adjust between 6β10 mm based on fiber length
Ideal Moisture Content: 10β12% for efficient pelletizing
Compression Ratio: Use 1:6 to 1:7 for rice husk-dominant blends
Binders: Natural lignin from sawdust/bamboo can improve binding & durability
