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.

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.

Product capability

Species and life stages, with the smallest pellet diameter required
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

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.
