Equipment Configuration of Fruit Shell Pellet Production Line
Equipment Configuration
1. Raw material pre-processing equipment
Biaxial Crusher for Coconut Shell Coarse Crushing: Made specifically to break down hard coconut shells into small chunks—this is the first step to getting ready for fine processing in fruit shell pellet production.
Hammer Crusher for Fruit Shell Fine Grinding: Takes the pre-crushed fruit shells and grinds them down to a 1-5mm powder (the perfect size for uniform fruit shell pellet granulation).
Vibrating Screen for Fruit Shell Impurity Removal: Sifts through the raw material to keep only the particles that meet granulation standards, filtering out dirt and oversized pieces to ensure high-purity fruit shell pellet feedstock.
Belt Conveyor for Continuous Fruit Shell Handling: Moves raw materials between every stage of production, so uninterrupted fruit shell pellet production flow is never an issue.
2. Drying equipment
Rotary Dryer for Fruit Shell Moisture Control: Uses a spinning cylinder with internal lifter plates to make sure fruit shells mix fully with hot air. It dries shells down to 10-15% moisture—key for getting stable fruit shell pellet formation.
Airflow Dryer (optional) for Large-Scale Fruit Shell Drying: Great for mass production, it uses high-speed hot air to dry shells in an instant—fast, efficient, and perfect for high-volume fruit shell pellet production lines.
3. Pelletising equipment
Ring Die Granulator (Core Fruit Shell Pellet Mill): This is the heart of fruit shell pellet production. It squeezes raw materials into fuel pellets using ring dies and pressure rollers, and you can pick different ring die sizes (4-8mm) to make pellets for industrial/residential fruit shell fuel use.
Flat Die Pellet Maker (optional): Simple design, lower cost—great for small production lines or if you don’t need super precise pellet shapes. It’s a solid choice for small-scale fruit shell pellet production.
4. Cooling and screening equipment
Counter-current Cooler for Fruit Shell Pellet Cooling: Makes hot pellets flow the opposite way of cold air, cooling them down fast with great results and low energy use. This boosts fruit shell pellet stability and water resistance so pellets hold up better.
Air-cooled Cooler (optional): Uses fans to blow cold air over pellets—good for small-scale production or if you don’t need strict cooling standards. It’s a budget pick for entry-level fruit shell pellet production.
Vibrating Screen for Finished Fruit Shell Pellet Screening: Sifts cooled pellets to get rid of oversized pieces, fine powder, and clumps. This ensures your finished pellets meet industrial fruit shell pellet quality standards.
5. Bagging equipment
Automatic Quantitative Bagging Machine for Fruit Shell Pellets: Measures and packages pellets with precision, and you can adjust packaging speed and sizes to fit market needs—boosting efficiency and quality for commercial fruit shell pellet sales.
Sewing Machine: Seals bags tight to keep moisture out, preserving fruit shell pellet quality during storage/transport.
Conveying and Palletising Equipment: Moves packaged pellets to the palletising area and stacks them neatly, making storage and logistics a breeze for bulk fruit shell pellet distribution.
Production Process of Fruit Shell Pellet Production Line
Production Process
1. Raw material pre-treatment for Fruit Shell Pellet Production
After collecting fruit shells, haul them to the plant’s stacking area and sift out impurities like leftover pulp or stones first. Then use a belt conveyor to send them to a biaxial crusher for coarse crushing, followed by a hammer crusher to grind them into fine powder. Finally, run them through a vibrating screen to get the right particle size—this keeps stable subsequent processing and high-quality fruit shell pellet formation.
2. Drying for Optimal Fruit Shell Pellet Moisture Content
Send qualified fruit shell powder to the dryer, using hot air or steam to get moisture down to 10-15%. This hits the humidity sweet spot for granulation, ensuring superior fruit shell pellet quality and combustion performance while making production more efficient and cutting energy costs.
3. Pelletising (Core Step of Fruit Shell Pellet Manufacturing)
Dried raw materials go into the granulator, and we add a bit of binder (like vegetable oil) and vegetable fibre in the tempering unit to get the right stickiness and moisture. Then ring dies and pressure rollers squeeze the material into dense fuel pellets—you can tweak diameter and length to match market demand, so you make custom-spec fruit shell fuel pellets for any combustion equipment.
4. Cooling and Sieving
Hot pellets from the granulator go to the cooler, where counter-current or air-cooled methods bring them down to near room temperature fast. This makes pellets more stable and water-resistant, so they don’t clump or go bad. Then a vibrating screen sifts out bad pellets, fine powder, and clumps—ensuring finished pellets are uniform, intact, and look good, which boosts fruit shell pellet qualification rate and market competitiveness.
5. Bagging and Storage for Commercial Fruit Shell Pellet Supply
Qualified pellets move to the bagging area, where an automatic quantitative bagging machine weighs and fills them to your specs. A sewing machine seals the bags tight, then palletising equipment stacks them neatly for easy storage and transport. This finishes the whole production process, so high-quality fruit shell pellets enter the market ready to go.
Raw Material Type of Fruit Shell Pellet Production Line
Raw material type
Peanut shells for Cost-Effective Fruit Shell Pellet Production
Lots of supply, moderate fibre content. Processed into pellets with solid quality, decent heat output, and low pollution when burned—an affordable choice for small-scale biomass fuel production.
Other nutshells for Diversified Fruit Shell Pellet Production
Almond shells, pistachio shells, betel nut shells, palm shells—all have high lignin fibre content. They’re great raw materials to mix in, expanding fruit shell pellet feedstock diversity.
Coconut shell for High-Fibre Biomass Pellet Production
High fibre, tough, and full of lignin. When processed, it becomes high-calorific-value pellets with stable flames and even heat release—ideal for industrial fruit shell pellet applications.
Walnut shell for Premium Fruit Shell Fuel Pellets
Hard, rich in lignin and cellulose, and with a high calorific value (4500-4800 kcal/kg). It’s the best raw material for fuel pellets—burns steady, lasts long, and heats efficiently, perfect for high-performance fruit shell biomass fuel.
Auxiliary materials for Fruit Shell Pellet Moulding
A little binder (like vegetable oil) makes raw materials stickier, which helps pellets form better. This improves fruit shell pellet production efficiency and combustion performance. .
