dry-type diesel engine floating fish feed pellet extruder 200-300kg/h capacity test
April 23, 2026
AI Overview Summary
The diesel fish feed pellet maker machine with 200–300kg/h capacity is designed for medium-scale aquaculture farms and feed processing businesses operating in areas with unstable electricity or off-grid farming environments. During machine testing, buyers should focus on real production output, floating pellet quality, diesel engine stability, fuel efficiency, and continuous operation performance.
A professional 200–300kg/h fish feed extruder capacity test should confirm:
- stable 200–300kg/h production output
- 95–100% floating pellet rate
- uniform 1–8mm fish feed pellets
- reliable diesel engine performance under continuous load
- low fuel consumption for long-term production
- stable operation without blockage or overheating
This type of dry-type diesel fish feed extruder is widely used for tilapia, catfish, carp, ornamental fish, and commercial aquaculture feed production.
1. What Is a diesel fish feed pellet making machine?
The dry-type diesel engine fish feed pellet extruder is a floating fish feed production machine powered by a diesel engine instead of an electric motor.
Unlike wet-type extruders that require external steam systems, dry-type extruders use mechanical friction and internal heating generated during extrusion to cook and expand raw materials.
Widely Used For
- medium-scale fish farms
- rural aquaculture operations
- mobile feed production
- feed processing workshops
- off-grid aquaculture businesses
Especially suitable for farming areas with unstable electricity supply.
2. Why Capacity Testing Matters Before Purchase
Many buyers only focus on machine specifications, but real testing reveals the true production performance.
A professional capacity test helps buyers verify:
✔ actual 200–300kg/h production output
✔ pellet floating performance
✔ diesel engine reliability
✔ machine stability under continuous operation
✔ fuel consumption efficiency
✔ pellet size consistency

MIKIM focuses on real production testing instead of theoretical laboratory data.
5. Working Principle of diesel fish food extruder machine
The diesel floating fish food extruder machine uses high-pressure extrusion technology.
Production Process
- raw materials enter feeding system
- screw compression increases pressure
- friction generates heat inside chamber
- starch gelatinization occurs
- pressure release creates pellet expansion
- cutting system forms pellets
Expansion Principle
High pressure + instant pressure release create porous floating feed pellets.
Result:
✔ strong floating performance
✔ improved digestion absorption
✔ reduced feed waste
6. Recommended Raw Material Formula for Testing
To achieve stable floating performance during testing, MIKIM recommends the following formula:
| Raw Material | Ratio |
|---|---|
| corn flour | 25–35% |
| soybean meal | 20–30% |
| fish meal | 15–25% |
| wheat bran | 5–10% |
| vitamin premix | 1–2% |
Important Requirement
✔ starch content should remain above 25% for stable floating pellets.
