Dryer capacity and energy in extruded aqua feed production
In extruded aquafeed the dryer commonly determines the sustainable production rate and a large share of the operating cost. Product leaves the extruder wet and must reach a stable moisture level; the lower the product density and the more humid the ambient air, the more drying capacity each tonne consumes. Specify the dryer against your worst case — lowest-density floating product, hottest and most humid month — and require fuel type, expected energy per tonne and the moisture-control method to be stated in the quotation. A line quoted on its extruder rate alone will underperform in practice.
Energy and drying are where extruded aquafeed economics are won or lost, and where quotations are least comparable.
Define your aquafeed line in a structured RFQWhat drives drying load
- Moisture added in preconditioning and extrusion
- Product density and expansion — floating feeds carry the highest load
- Pellet diameter and residence time in the dryer
- Ambient temperature and humidity at the site
- Target final moisture and its tolerance band
Fuel and energy decisions
- Available fuels at the site and their reliability, not just their price today
- Gas, diesel, biomass or electric heating, each with different capital and operating profiles
- Heat recovery options and their payback in your operating hours
- Expected energy per tonne, stated separately for grinding, extrusion and drying
What to require in every quotation
- Dryer capacity at your ambient design case, not at a generic reference
- Capacity per product for the lowest-density item in your portfolio
- Fuel type, consumption and burner scope
- Moisture measurement and control method
- Cleaning, hygiene and fire-safety design of the dryer
- Whether the dryer, its burner and its fuel supply are inside or outside the quoted scope
Dryer specification points
| Point | Ask for | Risk if omitted |
|---|---|---|
| Design case | Hottest, most humid month at site | Capacity shortfall in peak season |
| Worst product | Lowest density, smallest diameter | Line rate falls on the products you sell most |
| Energy | Expected energy per tonne | Operating cost surprises after startup |
| Fuel scope | Burner, fuel train, storage | Large excluded cost discovered late |
| Moisture control | Measurement and control method | Inconsistent shelf life and water stability |
| Hygiene and safety | Cleaning access, fire protection | Compliance and insurance issues |
Planning checklist for buyers. Engineering design remains the responsibility of your chosen supplier or engineer.
Questions buyers ask
Why is my line slower than the quoted capacity?
Is heat recovery worth it?
Should energy per tonne be contractual?

Write the requirement once and send the same document to every supplier you are considering, including one you already prefer. FeedMatch sells nothing and takes no part in the contract.
