hot sale 40-200kg/h single screw floating fish feed pellet making machine small

Product Specification

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).
