Aquatic Feed Extrusion Line

Floating & Sinking Fish Feed Production Line

Extrusion and drying solution for floating, slow-sinking and sinking aquatic feed. ZEKO matches the screw configuration, grinding, die, cutting and drying parameters to pellet diameter, density, water stability and the target species.

Pellet cooking and expansion begin in the fish feed extruder, while the dryer controls final moisture and storage stability. The floating fish feed guide explains the main factors affecting pellet quality and capacity.

Before shipment, agree the representative formula, pellet size, floating or sinking target, water-stability checks, output basis and open items with the factory acceptance test checklist.

Fish feed line selection brief

Three decisions define a stable aquatic feed line.

1. Species, formula and pellet sizeTarget species, ingredient mix and the required 0.8-12 mm pellet range determine grinding, conditioning, die, cutter and extrusion settings.
2. Floating or sinking behaviorFloating, slow-sinking and sinking feed require the corresponding screw configuration, formula control and density target; they are not selected by die size alone.
3. Saleable output and water stabilityExtrusion, drying, cooling and optional coating must be balanced around final moisture, water stability and the practical packed-product output.

Configure the Line Around Pellet Performance

A fish feed extruder is only one process stage. The complete line must control raw-material preparation, density, moisture and handling around the approved aquatic-feed product.

Define feed behavior firstConfirm whether each formula must float, sink slowly or sink. ZEKO then matches the screw configuration and process route to the required pellet density and species.
Control pellet size and water stabilityGrinding fineness, formula, conditioning, extrusion and drying all affect pellet integrity. Review the floating fish feed production guide before comparing equipment lists.
Balance downstream capacityThe dryer and cooler must handle the same practical load as the extruder. Use the capacity-planning guide and agree the acceptance basis before shipment.

Aquatic Feed Line Reference Configuration

Floating or sinking performance is controlled by formula, grinding, extrusion, pellet cutting and moisture management.

Extruder model / itemReference output / specification
ZK-85Approx. 500 kg/h
ZK-95Approx. 800-1,000 kg/h
ZK-130Approx. 2,000 kg/h
Common pellet diameterApprox. 0.8-12 mm; special sizes are reviewed by project
Typical pellet size bands0.8-1.2 mm fry, 1.5-2 mm fingerling, 2-4 mm grower, 4-6 mm adult, 6-12 mm large fish or broodstock
Feed behaviorFloating, slow-sinking or sinking through the corresponding screw configuration and process settings
Voltage options220 V, 380 V or 440 V; final electrical specification is project-specific
Dryer heat sourceElectricity, natural gas or steam
Construction options201 or 304 stainless steel according to the confirmed scope

These are reference outputs for larger aquatic feed lines in the ZEKO equipment schedule. Actual output varies with formula, pellet diameter, floating or sinking density target, moisture and dryer capacity; final performance is confirmed for the project.

Fish Feed Process, Materials and Utilities

The line is selected around species, pellet diameter, floating, slow-sinking or sinking requirement, formula and hourly output.

Typical Equipment Sequence
  1. Raw material crushing
  2. Batch mixing
  3. Conditioning and feeding
  4. Twin-screw extrusion
  5. Pellet cutting
  6. Moisture-controlled drying
  7. Cooling and screening
  8. Optional packing
The screw configuration is matched to floating, slow-sinking or sinking feed. Die and cutter selection are confirmed after the required pellet diameter range is provided.
Machine MaterialsFood-contact construction can be specified in stainless steel 201 or 304. Screw and wear-part specifications are confirmed for the formula and project.Electrical and Drying UtilitiesVoltage, frequency, installed power and dryer heat source are confirmed after capacity and pellet requirements are reviewed.
Production PlanningReference production time is 25-30 days for a complete line and 15-20 days for a single machine after the initial payment, subject to final configuration.StaffingStaffing depends on raw material preparation, automation, bag size and packing configuration.

Floating & Sinking Fish Feed Production Line FAQ

Practical answers about configuration, capacity, utilities and quotation planning.

Which ZEKO platforms and capacities are used for larger aquatic feed lines?

Reference outputs are approximately 500 kg/h for ZK-85, 800-1,000 kg/h for ZK-95 and 2,000 kg/h for ZK-130. Final output is confirmed against pellet size, formula, density target and dryer load.

Can one line make floating, slow-sinking and sinking feed?

Yes. ZEKO selects or changes the corresponding screw configuration for the required feed behavior, then adjusts the formula, grinding, extrusion settings, density target and drying conditions. Product testing may be required for a new formula.

Which fish feed pellet diameters can the line produce?

A common commercial range is approximately 0.8-12 mm. Typical bands are 0.8-1.2 mm for fry, 1.5-2 mm for fingerlings, 2-4 mm for grower feed, 4-6 mm for adult fish and 6-12 mm for large fish or broodstock. The die, cutter, formula and species determine the final size.

Are the listed fish feed capacities guaranteed?

No. The table provides reference outputs for model selection. Formula, pellet diameter, floating or sinking density, moisture and dryer load can change actual production capacity.

Which raw materials can be used?

Fish meal, grain flours, starch, soybean meal, protein ingredients, oils, vitamins and minerals may be used according to the buyer formula.

Which dryer heat sources are available?

Electricity, natural gas or steam can be evaluated according to capacity and local factory utilities.

What affects floating time and water stability?

Grinding fineness, formula, starch behavior, extrusion cooking, density, drying and final moisture all affect performance.

What affects the fish feed extruder line price?

Pellet size, capacity, crushing and mixing scope, extruder configuration, dryer, cooling, screening, packing and automation affect the quotation.
