Our small single screw floating fish food pellet maker machine is a portable, low-cost solution designed for family fish farms, backyard aquaculture, and small-scale hobbyists. This compact extruder produces 50–300 kg/h of high-quality floating pellets, enabling small-scale producers to make custom feed on-site. Easy to operate, maintain, and transport, it’s the ideal entry-level machine for small-scale aquaculture entrepreneurs.

Working Principle
The mini extruder uses simplified dry extrusion:

• Manual/Automatic Feeding: Small hopper feeds mixed raw materials into the screw chamber.
• Friction Heating: Single screw rotation generates friction heat (100–140°C); no external heating needed for basic models.
• Extrusion & Expansion: Materials compress, gelatinize, and exit the die; pressure drop creates porous floating pellets.
• Manual/Automatic Cutting: Basic hand cutting or small electric cutter for consistent lengths.

Structure Composition

• Feed Hopper: Small-capacity (20–50L) hopper with manual/electric feeder.
• Expansion Heating Device: Hardened small-diameter single screw + alloy barrel (wear-resistant).
• Host Motor: 7.5–15 kW electric motor or diesel engine (rural/off-grid use).
• Die Assembly: Replaceable small dies ((0.9–5 mm aperture) for different pellet sizes.
• Control Box: Simple button control (start/stop, speed adjustment).
• AdjustmentHandwheel: Light steel frame with wheels (easy transport/movement).

Product Parameters

Product Applications
Family/Backyard Fish Farms: 1–5 pond small-scale aquaculture.
Rural Smallholders: On-farm feed production from local crops (corn, rice bran).
Hobbyists/Ornamental Fish: Custom high-nutrition feed for koi/goldfish.
Small-Scale Feed Sellers: Local community feed production/sales.

Raw Material Requirements

1. Raw Materials: Corn flour, rice bran, wheat bran, soybean meal, fish meal, cassava flour.
2. Particle Size: 40–60 mesh (coarser than industrial models; easier grinding).
3. Moisture Content: 14–20% (add water if too dry; dry if overly wet).
4. Starch Content: ≥20% (ensures good expansion/floating ability).

FAQ
Q1: Can this mini electric floating fish feed extruder machine make durable floating pellets?
A: Yes. Proper raw material/moisture produces pellets floating 12+ hours; meets small farm needs.

Q2: Is it easy for one person to operate?
A: Yes. 1-person operation; feeding + cutting + packaging manageable.

Q3: What is the service life?
A: 3–5 years with proper maintenance; screw/barrel replaceable at low cost.

Q4: Can it run on single-phase electricity?
A: Yes. DGP-40/DGP-50 work on 220V single-phase (ideal for home use).

Q5: What is the delivery time for mini models?
A: 7–10 days (ex-factory); sea freight 15–30 days (global).
