RICHI MACHINERY recently signed a 6-ton-per-hour rice straw pellet production line project with a local agricultural investor in Central Java, Indonesia. The project marks another milestone in RICHI’s expanding footprint across Southeast Asia and reflects the growing regional demand for biomass pellet solutions based on agricultural residues.
Indonesia produces millions of tons of rice straw annually. Traditionally, much of this biomass has been burned or left to decompose in open fields, causing environmental concerns and wasted energy potential. The investor approached RICHI with a clear objective: transform surplus rice straw into high-density biomass pellets for industrial fuel and commercial heating applications.
After several rounds of technical discussions, RICHI’s engineering team proposed a customized processing solution designed specifically for long-fiber straw materials with variable moisture content.
Project Overview
The production line is designed for a stable output of 6 T/H and includes:
- Straw bale breaker and feeding system
- Hammer mill with anti-winding rotor design
- Rotary dryer for moisture reduction
- MZLH series biomass pellet mill
- Counterflow cooler
- Pellet screening system
- Automatic bagging and palletizing section
The entire system is optimized to handle rice straw with initial moisture levels of 18–25%, producing finished pellets with moisture below 10% and bulk density above 600 kg/m³.
RICHI also integrated a dust collection and cyclone system to meet local environmental standards and ensure clean workshop conditions.
Engineering Design Tailored for Rice Straw
Rice straw presents unique challenges due to its fibrous structure and silica content. To address this, RICHI adopted reinforced hammer blades, enlarged airflow channels, and specially treated ring dies to improve durability and reduce downtime.
The pellet mill is equipped with a forced feeding system to ensure consistent material flow, while the conditioning section allows optional binder addition for customers targeting export-grade pellets.
According to RICHI’s technical team, the line can process both loose straw and pre-baled raw materials, giving the investor flexibility in sourcing.
Project Timeline
The contract was finalized in January 2026. Equipment manufacturing is currently underway at RICHI’s production base, with shipment scheduled for early April. On-site installation is expected to begin in May, followed by commissioning and operator training.
- The full project is scheduled to enter commercial operation in the third quarter of 2026.
- Supporting Indonesia’s Biomass Energy Transition
Indonesia has been actively promoting biomass co-firing and renewable fuel initiatives. This project aligns closely with national energy diversification goals while creating new income streams for local farmers.
RICHI MACHINERY will provide full technical support, including layout design, installation guidance, process optimization, and after-sales service.
This rice straw pellet project further demonstrates RICHI’s capability to deliver reliable biomass pellet solutions tailored to regional agricultural resources.
