1.0–1.2 T/H Rice Husk Pellet Granulate Machine in South Korea

Customer Profile and Purchase Motivation

The client is a regional rice miller located near the city of Jeonju, processing roughly 40–60 tons of paddy daily during peak season. The client’s motivation for purchasing a single rice husk pellet making machine in South Korea was driven by multiple factors:

• Waste-to-energy conversion: Utilizing rice husks to produce fuel pellets reduces the cost of energy used for drying and processing rice.
• Environmental compliance: Open burning of rice husks is discouraged under South Korean environmental regulations; pelletizing provides a cleaner alternative.
• Revenue diversification: Surplus pellets can be sold to small-scale biomass power plants, bakeries, and local heating facilities.
• Operational flexibility: A single machine allows integration with existing milling operations without disrupting current workflows.

The decision to start with a single machine rather than a full pellet production line reflects the client’s cautious approach, ensuring they could evaluate market demand and operational efficiency before committing to a larger investment.

Raw Materials and Pellet Specifications

The primary raw material for this project is 100% rice husk, sourced directly from the milling process. Occasionally, small quantities of clean sawdust are added—no more than 5%—to slightly enhance pellet density. The rice husks have a typical moisture content of 10–12% after drying, which is suitable for efficient pelletizing.

The pellet diameter was set to 6 mm, balancing combustion efficiency, ash content, and compatibility with small industrial boilers in South Korea. The pellets are intended primarily for fuel purposes, although they could also serve as bedding for livestock or as feedstock for certain bio-based products.

Equipment Selection: Model and Parameters

Considering the production needs, local electricity rates, and the desired output, the customer chose the MZLH420 rice husk pellet granulate machine. This model provides a balance of production capacity, energy efficiency, and operational stability suitable for a mid-sized mill in South Korea.

This choice allows the mill to produce approximately 8–10 tons of fuel pellets daily, matching the scale of the milling operation and regional demand for biomass fuel. Smaller models, such as MZLH320 or MZLH350, would have insufficient output for the client’s needs, while larger models like MZLH520 or above would consume more energy than necessary, making them less cost-effective.

Shipping and Logistics

South Korea is well-connected by international sea routes. The RICHI rice husk pellet machine was shipped via sea freight from China, arriving at Busan Port, the largest port in South Korea. From Busan, RICHI coordinated domestic transport to the milling facility near Jeonju, ensuring safe and timely delivery.

RICHI’s logistics team handled all documentation, customs clearance, and transport arrangements, making the shipping process seamless for the client.

Installation and Commissioning

RICHI provided comprehensive support during the installation and commissioning phase:

• Site preparation: The machine was installed on a reinforced concrete foundation to prevent vibrations and ensure stability during operation.
• Electrical setup: The 90 kW main motor was connected to the local grid with voltage regulation to protect the equipment.
• Feeding adjustments: Rollers and ring die settings were fine-tuned to ensure consistent 6 mm pellet production.
• Operator training: Mill staff received hands-on training in operation, maintenance, troubleshooting, and safety protocols.

This guidance ensured immediate operational readiness and long-term reliability of the pelletizing process.

Application and Market Use

The rice husk pellets produced in this rice husk pellet granulate machine in South Korea project have multiple applications:

• Internal Energy: The pellets are primarily used to fuel boilers for rice drying, reducing the reliance on imported coal or firewood.
• Local Sales: Surplus pellets are sold to local biomass energy providers, bakeries, and brick kilns.
• Potential Export: South Korea has active trade with Japan and northern China; high-quality pellets could be sold for industrial fuel or biomass projects abroad.

The pelletized rice husk is dense, uniform, and easy to store, ensuring efficient combustion and minimal ash residue.

Advantages of the RICHI Rice Husk Pellet Granulate Machine

The client identified several advantages of RICHI’s equipment:

• Durability: High-quality rollers and wear-resistant ring die ensure long operational life, even with abrasive rice husks.
• Energy Efficiency: Despite the robust output, MZLH420 rice husk pellet granulate machine in South Korea is optimized for low energy consumption per ton of pellets.
• Flexible Pellet Size: Pellets from 4–12 mm can be produced, enabling customization for different applications.
• Professional Support: RICHI provides installation, training, and ongoing technical assistance.
• Scalable Investment: The single machine can later be expanded into a full pellet production line if demand increases.

Technical Insight: How the Pelletizer Works

The rice husk pellet granulate machine in South Korea converts loose rice husks into dense, cylindrical pellets through a ring die and roller compression system:

1. Feeding: The husks are introduced via the anti-caking and forced feeders to maintain consistent flow.
2. Compression: Rollers push the husks through the ring die under high pressure.
3. Pellet Formation: The compressed material exits the die as uniform pellets.
4. Cooling and Storage: Optional cooling prevents deformation, making pellets suitable for storage and transport.

This method increases energy density, reduces storage volume, and produces a marketable, eco-friendly fuel.

Environmental Impact

Using rice husks for pellet production aligns with South Korea’s green energy initiatives:

• Reduces open burning of agricultural residues.
• Lowers carbon emissions compared to fossil fuels.
• Provides a renewable energy source for small-scale industrial and domestic use.

The client’s project demonstrates practical environmental responsibility while creating economic benefits.

Future Plans

The rice mill plans to explore several expansions:

• Adding pellet cooling and packaging systems for better product presentation and market reach.
• Testing biomass co-firing in nearby small power plants.
• Upgrading to higher-capacity MZLH520 or MZLH678 machines if domestic demand grows.

The rice husk pellet granulate machine in South Korea project sets the foundation for a sustainable biomass energy business in South Korea.

Conclusion

This case illustrates how a mid-sized rice mill in South Korea can leverage rice husk pellet granulate machines to convert agricultural waste into valuable energy resources. By purchasing a single RICHI rice husk pellet machine, the mill achieved:

• Efficient waste management
• Sustainable fuel production
• Potential revenue generation from surplus pellets
• A scalable solution for future biomass energy needs
