This is a project about a rice husk pellet making machine in Brazil. A medium-sized rice milling cooperative in Rio Grande do Sul explored sustainable solutions for rice husk management. The cooperative aimed to convert rice husks into high-quality fuel pellets to reduce energy costs in their drying operations and explore additional revenue through commercial pellet sales.
This is a project about a rice husk pellet making machine in Brazil. Brazil is one of the largest rice producers in South America, with annual rice production concentrated in the southern states such as Rio Grande do Sul, Santa Catarina, and Paraná. These regions generate significant amounts of rice husks as a byproduct of rice milling operations. Traditionally, many rice mills either burned these husks in open fields or used them as low-value filler material, creating environmental concerns and underutilizing a potentially valuable biomass resource.
A medium-sized rice milling cooperative in Rio Grande do Sul explored sustainable solutions for rice husk management. The cooperative aimed to convert rice husks into high-quality fuel pellets to reduce energy costs in their drying operations and explore additional revenue through commercial pellet sales. Instead of investing in a full-scale husk biomass pellet production line, the client opted for a single rice husk pellet making machine in Brazil, which offered flexibility, cost-effectiveness, and a scalable solution for testing market demand before committing to larger infrastructure.
Name:
rice husk processing machine
Country:
Brazil
Date:
2025
Capacity:
1.5–2.0 T/H
Pellet Size:
6–8 mm
Model:
MZLH520
Main Motor Power:
132 kW
Ring Die Inner Diameter:
520 mm
The client is a cooperative of local rice farmers managing a facility capable of processing 100–120 tons of paddy per day. Their primary challenges were:
By purchasing a single rice husk pellet making machine, the client intended to:
The rice husk pellet machine approach is ideal for mid-scale operations in Brazil, offering low initial investment and high flexibility without the commitment of a full production line.
The main raw material for this rice husk pellet making machine in Brazil project is 100% rice husks, collected directly from milling operations. Occasionally, small quantities (5% or less) of wood sawdust or bagasse are added to increase pellet density and calorific value, but the vast majority is pure rice husks.
The final pellet diameter is set between 6–8 mm, optimized for combustion in industrial dryers and small-scale biomass boilers. This size ensures:
These pellets meet local standards for biomass fuel and are suitable for both internal use and commercial sale.
After evaluating production needs and local conditions, the client selected the MZLH520 rice husk pellet making machine. This model is appropriate for medium-scale operations, balancing production capacity with energy consumption.
| Model | MZLH520 |
|---|---|
| Main Motor Power | 132 kW |
| Production Capacity | 1.5–2.0 T/H |
| Anti-Caking Feeder Power | 3 kW |
| Forced Feeder Power | 1.5 kW |
| Ring Die Inner Diameter | 520 mm |
| Pellet Diameter Range | 4–12 mm (set to 6–8 mm) |
This configuration allows the cooperative to process approximately 12–16 tons of rice husk pellets per day, sufficient to meet both internal energy requirements and local market demand. Smaller models, such as the MZLH420, would not meet production targets, while larger models would unnecessarily increase energy consumption and investment costs.
For this project, the rice husk pellet machine was shipped from China via sea freight to the Port of Santos, Brazil’s largest maritime port and a key hub for industrial imports. From Santos, the machine was transported by truck to the cooperative’s facility in Rio Grande do Sul.
RICHI Machinery managed the complete logistics process, including:
RICHI Machinery provided comprehensive on-site support to ensure smooth installation and immediate operational readiness:
The rice husk pellets produced with the MZLH520 rice husk pellet making machine in Brazil have multiple applications:
This project illustrates how a medium-sized rice milling cooperative in Brazil can convert rice husk waste into high-quality biomass fuel pellets using a single rice husk pellet making machine. The MZLH520 model rice husk pellet making machine in Brazil provides:
The cooperative successfully minimized waste management issues, reduced energy costs, and created new revenue streams. Partnering with RICHI Machinery provided not only a high-quality pelletizer but also professional guidance, logistics support, and technical assistance, demonstrating the value of investing in RICHI solutions for sustainable and profitable biomass pellet production in Brazil.
