Supplier selection
How to choose an aqua feed extrusion supplier
Short answer
Choose an extrusion supplier on product capability first: the species and pellet diameters you must produce, whether feed must float or sink, target density and water stability, and the oil inclusion level you need to apply post-extrusion. Capacity in tonnes per hour changes substantially with pellet diameter and density, so the guarantee must name the product, not just the machine. Then evaluate the dryer and cooler duty, the vacuum coater, moisture control, energy per tonne, sanitation design, and the commissioning support that gets your first commercial recipes stable — process start-up assistance matters more in extrusion than in pelleting.
Questions buyers ask
How do I compare aqua feed plant proposals?
Normalise on product, not on machinery: state species, pellet diameters, density, water stability and oil inclusion, then compare guaranteed capacity at the binding product, dryer and cooler duty, coating scope, energy split between extrusion and drying, automation, installation and commissioning support at equal scope.
Do I need a twin-screw extruder?
It depends on product range, fat inclusion and diameter range rather than on general superiority. Define the product envelope you must cover over the plant's life, then let suppliers justify the configuration against it.

Aqua feed lines are product-defined. A shrimp feed plant, a floating tilapia line and a high-fat salmonid line are three different machines wearing similar names.

- Floating, slow-sinking or sinking, and the density window per product
- Water stability requirement and the test method used to verify it
- Maximum oil inclusion and whether vacuum coating is required
- Micro-pellet or crumble capability where fry feed is in scope
Line configuration
- Single or twin screw and the reason for the choice in your product mix
- Preconditioner retention time and steam or water injection capacity
- Capacity at your smallest diameter and highest density, stated separately
- Dryer type, retention time and moisture uniformity target
- Cooler duty, vacuum coater and post-coating handling
Operating economics
- Energy per tonne split between extrusion and drying
- Steam, water and thermal fuel demand
- Screw, die and knife wear life and cost per tonne
- Changeover time between products and resulting utilisation
Start-up and support
- Process commissioning support with your own formulations
- Recipe development or trial facility access
- Operator training depth on density and moisture control
- Service reach and spare availability in your region
Questions to put in writing
- What capacity do you guarantee at our smallest diameter and target density?
- What water stability can we expect on our formulation, tested how?
- What are the total energy and thermal demands for extrusion plus drying?
- What process commissioning support is included, in days on site?
- What are the wear-part life and cost per tonne on this product mix?
Signals that deserve a second look
None of these mean a supplier is unsuitable. They mean the proposal needs clarification before it is comparable.
- One capacity figure with no diameter or density reference
- Dryer sized without a stated moisture in/out basis
- Water stability claimed without a test method
- Process commissioning support left unquantified
