This is a project about a shrimp feed pellet mill in Bolivia. The goal of this project was clear: produce stable, small-diameter sinking shrimp feed pellets locally, using regional raw materials and an advanced pelletizing solution that could integrate seamlessly with existing grinding and mixing equipment.
This is a project about a shrimp feed pellet mill in Bolivia. Although Bolivia is a landlocked country, aquaculture has been developing steadily in recent years, particularly in lowland tropical regions such as Santa Cruz and Beni. With warm water resources, artificial ponds, and increasing technical support from neighboring aquaculture markets, Bolivian producers have begun experimenting with freshwater shrimp and prawn farming, mainly for regional consumption and niche markets.
This project originates from a regional aquaculture feed processor closely linked to several freshwater shrimp farms. The client is not a traditional large shrimp feed factory, but rather a specialized aquatic feed supplier that serves cooperative farms, research-oriented aquaculture projects, and semi-intensive pond systems. Their focus is on sinking shrimp feed, adapted to freshwater conditions rather than marine shrimp farming.
Previously, the client relied on imported finished shrimp feed from neighboring countries, which resulted in high costs, unstable supply cycles, and limited formula flexibility. As feed prices continued to rise, the client decided to localize part of the production process by investing in a standalone shrimp feed pellet mill, instead of a full shrimp feed production line.
The goal of this project was clear: produce stable, small-diameter sinking shrimp feed pellets locally, using regional raw materials and an advanced pelletizing solution that could integrate seamlessly with existing grinding and mixing equipment.

In Bolivia, aquafeed producers often operate under space, power, and investment constraints. For this client, purchasing a complete shrimp feed production line would have required major civil works and a long payback period. However, the client already owned:
What they lacked was a professional shrimp feed pelletizer capable of forming dense, uniform, sinking pellets with reliable water stability.
By purchasing only one ring die shrimp feed pellet mill, the client was able to:
This single-machine strategy is particularly well-suited to Bolivia’s developing aquaculture market, where demand is growing but still highly regionalized.
After evaluating the client’s production goals and market size, RICHI Machinery recommended a compact yet professional ring die shrimp feed pellet mill that balances output with precision.
The client purchased SZLH250 shrimp feed pellet mills (two units of the same model), allowing flexible operation and ensuring continuity during maintenance.
| Parameter | Value |
|---|---|
| Main motor power | 22 kW |
| Feeder power | 1.1 kW |
| Conditioner power | 1.5 kW |
| Ring die inner diameter | 250 mm |
| Pellet diameter range | 1.5–2.2 mm |
| Production capacity | 0.2–0.4 T/H per machine |
With two shrimp feed pellet machines operating alternately or simultaneously, the client can match production closely with real demand, avoiding overproduction while maintaining supply stability. This capacity level is realistic for Bolivia’s current shrimp aquaculture scale and aligns with the client’s cautious expansion strategy.
The shrimp feed pellet machine in this project is dedicated to sinking aquatic feed, specifically designed for freshwater shrimp and prawn species cultivated in Bolivia.
The ring die shrimp feed pelletizer is not used for floating fish feed, as its structural design and conditioning system are optimized for dense sinking pellets rather than extruded floating products.
These small pellet sizes demand precise die machining and stable conditioning—key advantages of professional shrimp feed pellet mills over generic livestock feed pellet machines.
Bolivia’s shrimp feed formulas rely heavily on locally available agricultural and protein resources, minimizing dependence on imported marine ingredients.
The shrimp feed pellet press handles these mixed formulations efficiently, even with variations in fiber content and protein sources, ensuring consistent pellet quality across batches.
A defining feature of this shrimp feed pellet mill is its three-layer conditioner, a configuration typically reserved for high-end aquafeed applications.
For this project, the client selected a triple-layer steam conditioner with adjustable paddles and retention time, customized for freshwater shrimp feed formulas.
This advanced conditioning system offers:
Compared to single-layer or standard conditioners, the triple conditioner significantly improves pellet durability and reduces fines, which is critical for shrimp that feed slowly at the pond bottom. This configuration places the SZLH shrimp feed pelletizer on par with international aquafeed pellet mill standards.
Once the shrimp feed pellet mills were installed and commissioned, the client reported noticeable improvements in daily production performance.
The machines delivered:
Most importantly, the client gained the ability to fine-tune shrimp feed formulas based on growth performance feedback from farms—something that was impossible when using imported finished feed.
As Bolivia does not have direct access to the sea, all shrimp feed pellet mills for this project were shipped by sea from Qingdao Port, China, to a regional transit port commonly used for Bolivian imports.
The destination port selected for this project was Arica Port, Chile, one of the closest and most frequently used seaports for Bolivian industrial equipment imports. This shipping route is well-established and reliable for heavy machinery destined for Bolivia.
Beyond equipment supply, RICHI Machinery provided comprehensive technical services throughout the project, including:
Our engineers also shared insights on moisture control, steam usage, and mash fineness, ensuring the shrimp feed pellet mill performs consistently under local conditions.
With the shrimp feed pellet mills operating reliably, the client is now exploring several expansion directions:
The modular design of ring die shrimp feed pellet machines allows these expansions without disrupting existing operations.
This shrimp feed pellet mill project in Bolivia demonstrates how advanced ring die technology can support aquaculture development even in landlocked countries.
Whether referred to as a shrimp feed pellet mill, shrimp feed pellet machine, shrimp feed pelletizer, or shrimp feed pellet press, this equipment has proven to be a reliable and cost-effective solution for localized shrimp feed production.
By combining industry-leading triple-layer conditioning, precise pellet control, and professional technical support, RICHI Machinery continues to help aquaculture producers turn emerging opportunities into sustainable businesses—making every investment in shrimp feed pelletizing truly worthwhile.
