200 kW Spent Coffee Grounds Pellet Machine for Biomass Fuel Production – Italy

Italy has a large coffee consumption market, generating significant volumes of spent coffee grounds every day from cafés, restaurants, and industrial coffee processors.
Disposal of this organic waste has become costly, while demand for renewable biomass fuel continues to grow.

The customer planned a waste-to-energy project to convert spent coffee grounds into high-density biomass pellets, creating additional revenue while reducing landfill waste.

The customer is a biomass fuel producer in Italy, collecting coffee waste from local coffee chains and roasting plants.

Application scenario includes:

• Recycling spent coffee grounds
• Producing biomass pellets for heating and energy use
• Commercial pellet sales to industrial and residential users

Raw material conditions:

• Moisture content ≤ 20%
• Particle size < 10 mm

We provided a complete pelletizing solution centered on a DR678 large-capacity coffee waste pellet press.

Process flow:
Material preparation → Screw conveying → Forced feeding → Ring die pelletizing → Cutting → Pellet cooling and storage

Main equipment configuration:

• DR678 biomass pellet machine (200 kW)
• PLC automatic control system
• Timed forced feeder to prevent blockage
• High-precision gear-driven transmission
• Automatic lubrication system (no shutdown required)

If the customer lacks a full processing system, we also provide turnkey solutions, including drying and conveying systems.

• Model: DR678
• Capacity: 3–4 tons/hour
• Main motor power: 200 kW
• Pellet diameter: 6–12 mm
• Pelletizing chamber temperature: ~90°C (aerodynamic control)
• Energy consumption: approx. 30% lower than conventional pellet machines

Line advantages:

• Stable continuous operation
• Low blockage rate
• High pellet density and uniform size
• Durable stainless steel / ductile iron machine body

The pellet machine was tested, packed in reinforced export packaging, and shipped to Italy.

Customer feedback:

“The machine runs smoothly with high output and low energy consumption. We are now turning coffee waste into a profitable biomass fuel product."
