This project concerns a tilapia and shrimp mixed feed extruder in Ecuador. In 2025, a commercial aquafeed manufacturer located near Guayaquil, Ecuador invested in a new twin-screw feed extrusion system to modernize its production operations.
In 2025, a commercial aquafeed manufacturer located near Guayaquil, Ecuador invested in a new twin-screw feed extrusion system to modernize its production operations.
As one of the country's established feed producers serving both the shrimp farming and tilapia farming sectors, the company had been operating two aging single-screw extruders for many years—one dedicated to floating tilapia feed and the other used for sinking shrimp feed production.
As maintenance expenses continued to increase and production flexibility became more important, the company decided to replace both old machines with a single high-capacity twin-screw extrusion system capable of producing both floating and sinking aquatic feeds.
After evaluating several equipment options, the customer selected one RICHI SPHS150×2 twin-screw tilapia shrimp mixed feed extruder.

Ecuador is recognized as the world's largest shrimp exporter and one of Latin America's fastest-growing tilapia producers.
The local aquaculture industry demands both high-quality floating fish feed and highly stable sinking shrimp feed.
The customer's existing production setup consisted of two separate single-screw extruders:
After years of operation, both systems were facing several challenges:
The customer wanted a more efficient solution capable of handling both product categories while reducing equipment ownership costs.
The customer compared multiple models from the RICHI SPHS twin-screw fish feed extruder series.
Although this model offered lower investment costs, its production capacity was insufficient for the customer's long-term requirements.
This larger model provides higher output but requires a 355kW main motor.
Installing the machine would have required a significant electrical infrastructure upgrade costing more than USD 50,000.
The SPHS150×2 tilapia shrimp mixed feed extruder in Ecuador offered the best balance between investment cost, operating efficiency, and production capacity.
Key advantages included:
The selected SPHS150×2 tilapia shrimp mixed feed extruder includes:
| Parameter | Specification |
|---|---|
| Model | SPHS150×2 |
| Main Motor Power | 200kW |
| Conditioner Power | 15kW × 2 |
| Screw Diameter | 150mm |
| Extrusion Type | Twin-Screw |
| Feed Type | Floating and Sinking |
| Application | Aquaculture Feed |
The tilapia shrimp mixed feed extruder in Ecuador is equipped with a differential-speed conditioner that improves raw material preconditioning before extrusion.
This feature is particularly beneficial when switching between high-starch tilapia formulations and high-protein shrimp formulations.
The customer primarily uses plant-based ingredients for tilapia feed production.
| Ingredient | Percentage |
|---|---|
| Soybean Meal | 45% |
| Wheat Flour | 30% |
| Rice Bran | 15% |
| Fish Meal | 5% |
| Vegetable Oil | 5% |
Shrimp feed requires significantly higher protein content and enhanced palatability.
| Ingredient | Percentage |
|---|---|
| Fish Meal | 30% |
| Soybean Meal | 20% |
| Wheat Flour | 15% |
| Rice Bran | 10% |
| Shrimp Head Meal | 10% |
| Squid Meal | 10% |
| Fish Oil | 5% |
The fish meal is sourced locally from Ecuador's anchovy and tuna processing industry, while soybean meal is imported from the United States.
Following installation and commissioning, the SPHS150×2 tilapia shrimp mixed feed extruder achieved the following operating performance.
| Pellet Size | Output (T/H) | Type | Water Stability |
|---|---|---|---|
| 3.0mm | 5.0-5.5 | Floating | 15+ min |
| 4.5mm | 5.0-5.5 | Floating | 15+ min |
| 6.0mm | 5.0-5.5 | Floating | 15+ min |
| Pellet Size | Output (T/H) | Type | Water Stability |
|---|---|---|---|
| 1.0mm | 4.5-5.0 | Sinking | 45+ min |
| 1.5mm | 4.5-5.0 | Sinking | 45+ min |
| Pellet Size | Output (T/H) | Type | Water Stability |
|---|---|---|---|
| 2.0mm | 5.5-6.0 | Sinking | 50+ min |
The equipment was shipped from Qingdao Port, China, to Guayaquil Port, Ecuador.
| Stage | Duration |
|---|---|
| Sea Freight | 38 Days |
| Customs Clearance | 12 Days |
| Installation | 4 Weeks |
The installation project included:
During the first month of operation, several minor issues were identified and quickly resolved.
Cause:
Insufficient coating uniformity.
Solution:
Installation of a vacuum coating system.
Cause:
Minor imbalance in screw assembly.
Solution:
Dynamic screw rebalancing.
Cause:
Metal contaminants entering the extrusion system.
Solution:
Installation of a magnetic separator and raw material sifting system.
After eight months of commercial operation, the new extrusion system successfully replaced both older single-screw wet type fish feed extruders.
Key results achieved include:
The customer now operates a single extrusion platform capable of producing both floating tilapia feed and sinking shrimp feed while meeting the growing demand of Ecuador's aquaculture industry.
