Automatic Fish Feed Machine

Product Description:

An automatic fish feed machine is a fully automated extrusion system designed for continuous production of high-quality floating and sinking fish feed pellets. It combines advanced extrusion technology with PLC automation to deliver consistent, uniform pellets with minimal labor. It is ideal for commercial fish farms, feed mills, and aquaculture operations.

Floating vs. Sinking Pellets – What’s the Difference?

How It Works

Raw materials are ground into fine powder (under 0.5mm) and mixed with steam and water inside the machine. The twin-screw extrusion system cooks the starch at high temperature and pressure. When the cooked dough exits through the die, it expands. For floating pellets, expansion creates air pockets that keep them on the surface. For sinking pellets, less expansion makes them dense and heavy. The entire process is controlled by a PLC control system with a touch screen interface, allowing one operator to manage multiple machines.

Key Features

• Fully automatic operation – PLC control, touch screen interface, minimal labor required

• Dual production modes – produces both floating and sinking pellets with the same machine

• Adjustable pellet size – change the die to produce 0.5mm to 15mm pellets

• High water stability – pellets stay intact in water for 2–4 hours, reducing waste

• Stainless steel construction – food-grade, rust-resistant, easy to clean

• High gelatinization – 90%+ starch cooking, easy for fish to digest

• Continuous operation – can run 24/7 with minimal breaks for maintenance

• Energy efficient – optimized screw design reduces power consumption

What Fish Can It Feed?

Complete Automatic Fish Feed Production Line

A full production line typically includes:

1. Hammer mill – grinds raw materials into fine powder

2. Mixer – blends ingredients evenly

3. Automatic fish feed extruder – produces floating or sinking pellets

4. Dryer – removes moisture from pellets

5. Oil sprayer – adds fat or oil for nutrition

6. Cooler – brings pellets to room temperature

7. Packing scale – bags the final product

How to Choose the Right Automatic Fish Feed Machine

1. Floating or sinking? Floating requires an extruder with steam conditioning.

2. Capacity – small farm: 50–200 kg/h; commercial: 500–2000 kg/h.

3. Pellet size – fry need 0.5–1mm; adult fish need 4–10mm.

4. Automation level – semi-auto for small farms; fully automatic for commercial operations.

5. Power source – electric motor is standard; diesel available for remote areas.

6. Budget – small models start around $5,000–8,000; commercial lines $20,000–50,000+.

Why Choose Automatic Fish Feed Production?

• Save money – produce your own feed at 30–50% lower cost than buying commercial feed

• Control quality – choose exactly what goes into your fish feed

• Reduce waste – floating pellets let you see how much fish eat

• Fresh feed – produce on demand, no long storage

• Labor saving – one operator can manage the entire production line

Maintenance Tips

• Clean the die and screw after each use to prevent blockage

• Check cutter blades regularly – sharp blades make uniform pellets

• Lubricate gearbox every 500 hours of operation

• Use only dry, clean ingredients (moisture 20–30% for wet extrusion)

• Calibrate sensors and check electrical connections monthly

An automatic fish feed machine turns local ingredients into high-value aquafeed with minimal labor and maximum efficiency. Whether you run a small farm or a commercial feed mill, there is a model that fits your needs. Fully automated, built to last.
