This is a project about peanut shell pellet press in Vietnam. A medium-sized biomass fuel company in southern Vietnam sought to capitalize on this abundant resource. The company decided to invest in two peanut shell pellet presses from RICHI Machinery to convert peanut shells into high-density biomass pellets for industrial boilers and domestic stoves.
This is a project about peanut shell pellet press in Vietnam. Vietnam is one of Southeast Asia’s leading peanut producers, especially in provinces like Dong Nai, Tay Ninh, and Bac Lieu. Every year, large volumes of peanut shells are produced as agricultural by-products. Traditionally, these shells were either discarded or burned, causing environmental pollution and wasted energy potential.
A medium-sized biomass fuel company in southern Vietnam sought to capitalize on this abundant resource. The company decided to invest in two peanut shell pellet presses from RICHI Machinery to convert peanut shells into high-density biomass pellets for industrial boilers and domestic stoves. The purchase was specifically aimed at upgrading production efficiency and producing pellets with uniform quality and durability.
Prior to this purchase, the client relied on older small-scale pellet machines, which had low output and inconsistent pellet sizes. The decision to acquire single-unit pellet presses instead of an entire production line allowed the company to trial high-efficiency pelletizing while maintaining flexibility in their existing operations.
Name:
peanut shell pelletizer
Country:
Vietnam
Date:
2025
Capacity:
0.3–0.5 T/H
Model:
MZLH350
Main Motor Power:
37 kW
Arch-breaking feeder power:
2.2 kW

The client operates in Vietnam’s renewable energy and biomass fuel sector, focusing on fuel pellets made from agricultural residues. The raw materials primarily include peanut shells collected from nearby peanut processing facilities, often mixed with small amounts of peanut dust.
Based on the fibrous nature of peanut shells, RICHI recommended the MZLH350 peanut shell pellet press. This model was selected for its ability to handle light, fibrous materials efficiently and produce consistent pellets suitable for multiple end-use applications.
| Machine Specification | Value |
|---|---|
| Main motor power | 37 kW |
| Arch-breaking feeder power | 2.2 kW |
| Forced feeder power | 0.75 kW |
| Ring die diameter | 350 mm |
| Pellet diameter | 4–12 mm |
| Production capacity | 0.3–0.5 T/H per machine |
The client purchased two machines to operate simultaneously, allowing for continuous production and redundancy, ensuring minimal downtime for maintenance or operational issues.
Vietnamese peanut shells are lightweight, fibrous, and brittle, requiring careful pre-treatment before pelletizing. The client adopted the following steps:
The finished pellets are hard, uniform, and dense, suitable for industrial boilers, biomass stoves, and export markets.
The peanut shell pellet presses in Vietnam brought significant operational benefits:
With these machines, the client increased production efficiency by over 50%, produced uniform, market-ready pellets, and addressed growing local demand for biomass fuel.
The machines were shipped by sea freight to the Port of Ho Chi Minh City, Vietnam, which is the primary hub for importing industrial machinery. RICHI Machinery provided comprehensive support including:
This support ensured immediate operational readiness and smooth integration into the client’s existing production facility.
The MZLH350 peanut shell pellet press is a versatile machine, capable of processing:
Key technical features include:
This versatility allows clients to expand pellet production without investing in multiple machines.
The client provided feedback after a few months of operation:
"RICHI’s peanut shell pellet presses exceeded our expectations. The machines are reliable, easy to operate, and the pellets are uniform and durable. Installation and training were smooth, and the RICHI team has been very responsive. We have increased production capacity significantly and can now meet growing demand for high-quality biomass pellets in both domestic and industrial markets."
This demonstrates RICHI Machinery’s professionalism, product quality, and customer support.
