A mid-sized rice milling facility in Arkansas, processing approximately 150 tons of paddy per day, decided to invest in a single rice husk pellet machine in the United States to convert their rice husk waste into high-density fuel pellets.
This is a project about rice husk pellet machines in the United States. The United States is a leading global producer of rice, with significant cultivation concentrated in the states of Arkansas, California, Louisiana, Mississippi, and Texas. Every rice milling operation produces a substantial amount of rice husks as a byproduct, often underutilized and posing environmental management challenges.
A mid-sized rice milling facility in Arkansas, processing approximately 150 tons of paddy per day, decided to invest in a single rice husk pellet machine in the United States to convert their rice husk waste into high-density fuel pellets.
Rather than investing immediately in a full-scale husk biomass pellet production line, the client preferred starting with a single-machine solution for a manageable investment, operational flexibility, and testing the market potential of rice husk pellets locally.
The client’s objectives included:
This approach allowed the facility to gradually scale production without committing to a large infrastructure from the start.
Name:
rice husk pelletizer
Country:
United States
Date:
2025
Capacity:
1.5–2.0 T/H
Model:
MZLH420
Main Motor Power:
132 kW
Raw Materials:
100% rice husks
Pellet diameter:
6–8 mm
The client is a medium-scale rice processor focusing on both white rice production and byproduct management. Their motivation for purchasing a single rice husk pellet making machine included:
Choosing a single rice husk pellet machine provided a lower initial investment while allowing the client to measure ROI and operational efficiency before scaling further.
The primary raw material is 100% rice husks, directly sourced from the milling process. Occasionally, small amounts of corn husks or wheat straw are blended to slightly increase calorific value, but the proportion rarely exceeds 5%. The cooperative aims to produce pellets suitable for fuel, not animal feed.
The target pellet size is 6–8 mm in diameter, optimized for industrial boilers and biomass heating systems. Key benefits of this pellet size include:
These specifications allow the rice husk pellets to serve both internal energy needs and the local commercial biomass market.
| Model | Main Motor Power | Production Capacity |
|---|---|---|
| MZLH520 | 132 kW | 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 facility to produce approximately 12–16 tons of rice husk pellets per day, matching the facility’s rice husk output and regional demand. A smaller model, such as the MZLH420, would not meet production targets, while larger machines would lead to excessive energy consumption for a mid-scale operation.
The rice husk pellet machine was shipped from China via sea freight to the Port of Houston, one of the busiest ports in the United States and conveniently located for transportation to Arkansas. From the port, the equipment was transported by truck to the milling facility.
RICHI Machinery managed the entire logistics process, including:
