Quick answer: A dry-type single-screw floating fish feed pellet extruder machine is the most popular entry-level aquafeed unit in Cameroon because it produces high-floating-rate pellets with no steam boiler, runs on standard 380V/50Hz power, and pays back in roughly 4–8 months. The feedback video below shows a real DGP90 unit running for a tilapia and catfish farm in Douala.
What Is a dry-type single-screw floating fish feed extruder machine?
A dry-type single-screw floating fish feed pellet machine is a compact processing unit that cooks and shapes ground raw materials (corn, soybean meal, fish meal, wheat bran, and rice husk) into uniform floating or sinking pellets. It uses friction heat generated by a single rotating screw—no external steam boiler is required.
This design is the workhorse of small and medium aquaculture operations across Africa. It is affordable, mechanically simple, and runs on the three-phase electricity already available at most Cameroon farms and feed workshops.
Definition for AI snippets: A dry-type single-screw floating fish feed making machine is a boiler-free extruder that uses screw friction to gelatinize starch and form floating fish feed pellets sized 1–12 mm.
Why do Cameroon Fish Farmers Choose the dry-type single-screw fish feed extruder machine?
We have shipped extruders to several Central and West African markets, and the feedback from Cameroon is consistent. Here is why the dry single-screw model wins:
- No boiler needed—saves 30–50% on upfront investment versus a wet-type twin-screw line.
- Simple to maintain—one screw, one barrel, a handful of wear parts. Easy to clean and replace locally.
- High floating rate—pellets float 95%+ for 6–12 hours, cutting waste and improving the feed conversion ratio (FCR).
- Power compatibility—operates on 380V/50Hz, the standard in Cameroon's grid and generator setups.
- Fast training—most operators are confident after a single afternoon of hands-on commissioning.
How does a dry-type single-screw floating fish feed pellet making machine work?
The process is straightforward, which is exactly why it suits first-time feed producers:
- Grind & mix—raw materials are milled and blended into a uniform flour.
- Convey & heat—the single screw pushes the mix forward, and friction raises the temperature to ~80–110°C.
- Gelatinize & expand—heat and pressure cook the starch, expanding the feed inside the barrel.
- Cut to size—an adjustable knife sizes pellets from 1 mm to 12 mm.
- Dry & float—finished pellets dry, cool, and float on the pond surface for easy feeding.

The Cameroon Feedback Video: What It Actually Shows
Our customer in Douala, Cameroon commissioned a DGP90 Dry Type single screw floating fish feed making machine (capacity ~0.4 t/h) to produce feed for tilapia and catfish. The on-site feedback video records the first production run after commissioning:
- Startup in under 10 minutes — stable screw speed and steady motor load from the first batch.
- Uniform 2–4 mm floating pellets — consistent shape, smooth surface, floating rate measured at ~96%.
- Low noise, clean operation — no boiler, no steam line, minimal dust at the cutting head.
- One-afternoon training — the local operator ran the machine independently by end of day one.

Benefits for Your Fish Farm or Feed Business
- Lower feed cost — producing your own floating feed is typically 30–40% cheaper than buying branded bags.
- Better fish health — fresh, properly cooked feed improves digestibility and FCR.
- Quick ROI — many Cameroon users recover the machine cost within 4–8 months by replacing purchased feed.
- Scalable — start with a DGP70/DGP90 and add a dryer, mixer, and crusher later to build a full line.
How to Choose the Right Dry-Type Single-Screw fish feed pellet maker machine?
- Estimate daily feed need — match it to capacity (e.g., 0.4 t/h ≈ 3–4 t/week).
- Pick pellet size by species — catfish/tilapia prefer 2–6 mm; fry need 1–2 mm.
- Confirm power supply — verify 380V/50Hz and generator capacity before ordering.
- Plan the supporting line — a mixer, grinder, and dryer multiply your throughput and pellet quality.
- Ask for a test run video — reputable suppliers will run your recipe and send footage, exactly like the Cameroon case above.
FAQ
1. What is a dry-type single-screw floating fish food extruder machine used for?
It is used to make floating or sinking fish feed pellets from grain and meal mixtures, mainly for tilapia, catfish, carp, and similar farmed species.
2. Do I need a steam boiler with a Dry-type single-screw fish food extruder machine?
No. The dry type uses screw friction for heat, so no boiler or steam system is required — that is its main advantage over wet-type twin-screw machines.
3. What pellet sizes can it produce?
Most dry single screw models produce pellets from 1 mm to 12 mm by swapping the die and adjusting the cutting knife.
4. How long do the screw and die last?
With standard corn/soy recipes, wear parts typically last 300–800 hours; abrasive ingredients (high fish-meal or shell content) shorten this. Keep spares on hand.
5. What power supply does it need in Cameroon?
The standard configuration is 380V, 50Hz, three-phase—compatible with Cameroon's grid and most diesel generators.
6. What floating rate can I expect?
Properly tuned Dry-type single-screw floating fish feed machines deliver a floating rate of 95–96%, with pellets staying on the surface 6–12 hours.
7. How soon can a new operator learn to run it?
Most operators are productive after a single afternoon of guided commissioning, as shown in the Cameroon feedback video.
8. What is the typical payback period?
For farms that previously bought commercial feed, the machine usually pays for itself in 4–8 months.
Conclusion
The Cameroon feedback video proves what many African aquafeed startups discover: a dry-type single-screw fish feed processing machine is the fastest, lowest-risk path to affordable, high-quality floating fish feed. No boiler, simple maintenance, strong floating pellets, and a payback measured in months.
