Aquafeed Extrusion Line Planner
Plan an aquafeed extrusion line: species, pellet size, floating or sinking, water stability, drying and coating. Indicative requirements plus a supplier quote checklist.
Indicative line requirements
- Extruder: Single-screw feasible; twin-screw adds flexibility
- Grinding fineness before extrusion: ≤ 500 micron
- Estimated drying load: ~934 kg water/hour (from ~26% at the die to ~9% finished moisture)
- Coating: Vacuum coater required for post-drying oil infusion
- Water stability: Moderate stability target — confirm with a documented test protocol
- Cooling and sifting sized to protect pellet integrity and remove fines
Supplier quote checklist
- ✓Pellet size range and tonnage per size
- ✓Floating, slow sinking or sinking requirement with density target
- ✓Water stability target and agreed test protocol
- ✓Formula ranges: protein, fat, starch and fibre
- ✓Oil inclusion and coating method
- ✓Available steam, power and compressed air
- ✓Site footprint and dryer placement
- ✓Budget range and target commissioning date

FAQ
What does the aquafeed extrusion line planner calculate?
It converts your species, pellet size range, capacity and water-stability target into indicative extrusion line requirements — extruder duty, drying load, coating need and the checklist a supplier needs before quoting.
Is the output an engineering design?
No. The output is indicative planning information only. Final line design requires supplier engineering, trials on your own formula and local regulatory review.
Why is the dryer usually the bottleneck?
Extruded feed leaves the die with high moisture that must be removed uniformly. Drying capacity, not extruder capacity, sets the achievable throughput in most aquafeed plants.
