Fish Feed

Fish Feed Drying

Fish feed drying follows extrusion, where pellets leave the die expanded, soft and carrying a lot of water. Whether the product must float for tilapia and carp or sink for catfish, buoyancy and pellet hardness depend on how that water is removed, and the dryer is where pellet density is finally fixed.

Quick answer

To dry fish feed, GEM recommends the Band Dryer (Beltotherm) and Multi-Pass Conveyor Dryer. Typical moisture is 20–28% in the feed and 8–10% after drying. Vibratory Fluid Bed Dryer and Industrial Cooler are used when the feed or site calls for it. Every project starts with a pilot trial on your own sample.

The challenge

What makes Fish Feed hard to dry

  • Expanded pellets have an open internal structure that dries quickly at the surface but slowly at the core.
  • Over-drying hardens the skin and causes floating pellets to crack or lose buoyancy after oil coating.
  • Several diameters, from 2 mm fry feed to 12 mm grow-out pellets, need different residence times on one line.
  • Pellets above the moisture target in tropical storage grow mould within weeks of bagging.
How GEM dries it

The right dryer for Fish Feed

Band and multi-pass conveyor dryers give the long, controlled residence that expanded pellets need for even core moisture. A vibratory fluid bed is used for small fry crumbles, and a cooler is always added before oil coating or bagging.

The value

What drying Fish Feed unlocks

Moisture uniformity decides shelf life in hot climates and protects the buoyancy farms pay for. Tighter control lets mills run closer to the moisture limit, selling more product weight without risking mouldy returns.

  • Floating tilapia and carp feed
  • Sinking catfish and pangasius feed
  • Fry and fingerling feed
For buyers

Buying a Fish Feed dryer?

Plants searching for a fish feed dryer or comparing a floating fish feed drying machine usually need three answers: which dryer fits, what it costs to run, and how fast it pays back. For Fish Feed, we start from your throughput, current moisture (typically 20–28%) and the target (8–10%), trial a sample on the Band Dryer, and return a sized recommendation with a budget quotation for your animal feed operation.

FAQ

Fish Feed: questions buyers ask

Why does my floating fish feed sink after drying?
Sinking usually comes from density set during extrusion, but over-drying and cracked surfaces can let water in. Balanced zone temperatures and correct final moisture help pellets keep the buoyancy created in the extruder.
Do I need a separate cooler after the fish feed dryer?
Yes in most plants. Pellets leave the dryer warm, and cooling to near ambient before oil coating or bagging prevents condensation inside bags and keeps the coating from soaking unevenly.
