Why Tanzania Clients Chose to Test the small fish feed pellet mill
During the visit, the clients focused on three main goals:
1. Verify Floating Performance
They wanted to confirm whether locally made feed could float consistently in water for catfish farming.
2. Test Raw Material Compatibility
Tanzania has abundant raw materials such as maize, soybean meal, and sunflower cake. Clients tested how well the machine adapts to local ingredients.
3. Evaluate Production Cost
They compared local production cost vs imported fish feed prices.
👉 This reflects a growing trend in Africa: shifting from imported feed to local feed production.
small floating fish feed pellet extruder mill Overview
The tested machine is a dry-type floating fish feed extruder designed for:
- Catfish feed production
- Tilapia feed processing
- Aquarium fish feed

Suitable for African power conditions (electric or diesel option)
On-Site Testing Process with Tanzania Clients
Step 1: Raw Material Preparation Test
Clients used local Tanzanian ingredients:
- Maize flour
- Soybean meal
- Fish meal
- Cassava starch
They confirmed that local raw materials are fully compatible with the machine.
Step 2: Mixing and Moisture Adjustment
Proper mixing ratio was tested:
- Protein source: 20–30%
- Energy source: 50–60%
- Additives: 3–5%
- Moisture: 20–25%
👉 The technician adjusted moisture level to optimize extrusion stability.
Step 3: small floating fish food pellet making machine Start-Up Test
The machine was started without load first:
- Motor stability checked
- Screw rotation verified
- Temperature rise monitored
Then raw materials were gradually fed into the hopper.
Step 4: Floating Feed Extrusion Test
During extrusion:
- Pellets expanded immediately
- Uniform size achieved
- High floating rate observed in water test
Clients tested pellets in water tanks and confirmed:
✔ Pellets floated for a long time
✔ No rapid sinking
✔ Good structural stability
Step 5: Pellet Cutting and Drying
- Adjustable cutter controlled pellet length
- Sun drying method used for demonstration
- Final pellets were hard, dry, and stable
Key Results from Tanzania Machine Testing
After the test, the following results were confirmed:
- Stable production performance
- Compatible with local raw materials
- High floating rate (>90%)
- Easy operation for local workers
- Low energy consumption
👉 Clients expressed strong interest in starting local fish feed production projects.
Why Small Fish Feed Extruder Machines Are Ideal for Tanzania Market
1. Reduces Imported Feed Dependence
Imported fish feed is expensive and unstable in supply.
2. Supports Local Aquaculture Growth
Fish farming is expanding in Tanzania and East Africa.
3. Uses Local Raw Materials
Maize, soybean, and cassava are widely available.
4. Low Investment Entry
Small machines allow startups with limited capital.
Common Problems During Fish Feed Machine Testing
Q1: Why do pellets sink during fish feed extrusion test?
Cause:
Low starch content
Too much oil or protein
Solution:
Increase maize or cassava ratio
Reduce oil addition before extrusion
Q2: Why is the machine producing uneven pellet size during testing?
Cause:
Cutter blade not adjusted properly
Feeding speed unstable
Solution:
Adjust cutter distance
Maintain consistent feeding rate
Q3: Why does the extruder machine block during operation?
Cause:
Raw materials too coarse
Moisture too high
Solution:
Improve grinding fineness
Reduce water content to 20–25%
Q4: Why is the floating rate low after extrusion?
Cause:
Insufficient gelatinization
Low extrusion temperature
Solution:
Increase starch content
Ensure proper machine warm-up
Q5: Why does the machine vibrate during production test?
Cause:
Loose installation
Uneven feeding load
Solution:
Tighten bolts
Feed materials evenly
Conclusion
The Tanzania client visit and testing of the small floating fish feed pellet extruder machine demonstrated that local fish feed production is not only feasible but also highly profitable in African markets.
With proper formulation, correct machine operation, and local raw materials, fish farmers in Tanzania can produce high-quality floating feed and significantly reduce farming costs.
This successful test confirms strong market potential for small-scale fish feed production businesses across East Africa.
FAQ
Q1: Why does the fish feed extruder produce sinking pellets during testing?
Usually due to low starch content or excessive oil in the formula. Adjust ingredient ratio before extrusion.
Q2: Why is pellet size inconsistent during machine testing?
This is often caused by improper cutter adjustment or unstable feeding speed.
Q3: Why does the machine stop during fish feed production test?
Caused by overload or blockage from coarse raw materials. Improve grinding and reduce feeding rate.
Q4: Why is floating performance weak in water test?
Insufficient gelatinization or low temperature during extrusion. Ensure proper machine warm-up.
Q5: Why does the extruder vibrate during operation?
Usually due to loose installation or uneven material feeding. Tighten bolts and stabilize feeding system.
