1.0–1.2 T/H Rice Straw Pellet Making Machine in Vietnam

Client Profile and Equipment Purpose

The client is a medium-sized biomass fuel producer located in the Mekong Delta region. Their operation centers around converting agricultural residues into high-value biomass products. The standalone purchase of two machines allows them to experiment with different rice straw blends and pellet sizes while maintaining ongoing operations.

The purposes of the purchased rice straw pellet making machines in Vietnam include:

• Fuel pellets: Producing high-density rice straw pellets for local biomass boilers and industrial heating systems.
• Animal bedding pellets: Converting straw into absorbent pellets suitable for poultry, pig, and cattle farms.
• Experimental biomass applications: Investigating rice straw pellets for biochar production or small-scale pelletized industrial feedstock.

The machines were newly purchased to complement existing shredding and drying equipment, allowing the client to upgrade their production quality and expand pellet types without fully replacing older systems.

Raw Materials and Machine Selection

Vietnam’s rice harvest provides a consistent supply of straw. The client’s raw materials include:

• Dry rice straw, collected from local rice fields across the Mekong Delta.
• Mixed straw residues, including husks and leftover rice stalks, to improve pellet durability.
• Chopped straw, typically 30–40 mm in length, optimal for ring die pelletization.

The client aimed to produce pellets with diameters of 6–10 mm, ideal for both fuel and animal bedding applications. After evaluating production needs, they selected the MZLH420 model:

• Main motor power: 90 kW
• Arch-breaking feeder power: 3 kW
• Forced feeder power: 1.5 kW
• Ring die diameter: 420 mm
• Pellet diameter: 4–12 mm (adjustable)
• Production capacity: 1.0–1.2 T/H per machine

With two MZLH420 rice straw pellet making machines in Vietnam, the client achieves a combined production capacity of 2–2.4 T/H, matching medium-scale production requirements and allowing flexibility for trial blends of rice straw and other agricultural residues.

Production Process and Applications

The rice straw pellet making machines in Vietnam operate through a carefully controlled process:

1. Pre-processing: Rice straw is cleaned, chopped, and dried to 12% moisture content, ensuring proper pellet formation.
2. Pelletizing: The MZLH420 machines press straw into dense, uniform pellets.
3. Cooling and packaging: Pellets are cooled to prevent deformation and then bagged for shipment or storage.

Applications of the rice straw pellets include:

• Biomass fuel: Dense, energy-rich pellets for boilers and power generation.
• Animal bedding: Pellets suitable for poultry, pigs, and dairy cattle, providing high absorbency and reduced waste handling.
• Experimental products: Rice straw pellets can be used for small-scale biochar or industrial biomass feedstock research.

The client highlighted that the MZLH420 produces consistently sized, durable pellets, critical for both fuel efficiency and handling in bedding applications.

Technical Features and Advantages

The rice straw pellet making machine in Vietnam offer several key benefits:

• Versatility: Capable of processing rice straw, husks, and other crop residues.
• Adjustable pellet sizes: Produces pellets from 4–12 mm to accommodate different applications.
• Energy efficiency: Optimized design for high output with lower energy consumption.
• Standalone operation: Ideal for medium-scale facilities and pilot projects.
• Durability and low maintenance: Designed for continuous industrial use.

The client specifically chose RICHI Machinery for its reputation in providing reliable biomass pellet machines, along with professional support including installation guidance, operator training, and technical assistance.

Logistics and Delivery

The straw pellet making machines were shipped by sea to Hai Phong Port, the closest major seaport for receiving industrial equipment in northern Vietnam. RICHI Machinery ensured secure packaging, accurate documentation, and timely delivery, allowing the client to begin pellet production shortly after arrival.

Client Feedback

"The rice straw pellet making machines have transformed our biomass operations. They produce high-quality, uniform pellets that meet fuel and bedding standards. The machines are easy to operate, energy-efficient, and require minimal maintenance. RICHI’s technical team provided excellent guidance and support, making the installation and startup process smooth. We are now considering expanding our pellet production line with more machines in the near future."

Strategic Impact and Future Outlook

Investing in rice straw pellet making machines in Vietnam offers several advantages:

• Efficient utilization of abundant rice straw to generate renewable energy and bedding products.
• Diversification of pellet products to meet domestic fuel and agricultural markets.
• High-quality, durable pellets for reliable energy generation and farming applications.
• Gradual scaling potential through standalone operation before committing to full production lines.

RICHI Machinery’s versatile, robust machines and professional support allow clients in Vietnam to capitalize on local resources while reducing environmental impact and increasing revenue from straw residues. This case demonstrates the value of standalone rice straw pellet making machines as a practical, cost-effective solution for medium-scale biomass producers.
