How is food made with a small Floating fish feed Making machine?

Producing floating fish feed with a specialized machine involves a systematic, automated process that transforms powdery raw materials into nutritionally balanced, buoyant pellets. Below is a step-by-step breakdown of the workflow, tailored to the operation of high-quality machines like MIKIM's twin-screw extruders (widely recognized for efficiency and feed quality):

1. Raw Material Preparation & Formulation

First, design a scientific formula based on target fish species (e.g., tilapia, salmon, koi) and growth stages. Core ingredients include:

Protein sources (fish meal, soybean meal, wheat gluten: 30-50% of the mix),

Energy sources (corn flour, wheat bran: 20-40%, critical for floatability),

Fat sources (fish oil, soybean oil: 5-15%),

Vitamins, minerals, probiotics, and binders (1-3%).

Raw materials are crushed into 80-100 mesh fine powder via a hammer mill, then accurately weighed and pre-mixed in a horizontal mixer for 5-10 minutes to ensure uniform distribution of nutrients. Impurities (stones, metal) are removed via a magnetic separator to protect the machine's screws and die.

2. Preconditioning (Moisture & Temperature Adjustment)

The mixed powder is conveyed into a preconditioner (a key component of high-end machines like MIKIM's) via a frequency-controlled feeder. Steam and purified water are injected to adjust moisture content to 16-18% and temperature to 85-95°C. This step softens the material, initiates starch gelatinization, and enhances subsequent extrusion efficiency. Top-tier machines feature dual-shaft paddles and extended residence time (3-5 minutes) for thorough heat and moisture integration.

3. Extrusion: Core Molding & Floatability Formation

The conditioned material enters the extruder barrel (twin-screw for optimal performance). As the intermeshing screws rotate (100-600 rpm), they generate intense shear force, pressure (5-10 MPa), and friction heat (110-130°C). This process fully gelatinizes starch (degree ≥85%), denatures proteins, and mixes ingredients uniformly.

When the material exits the die's customized holes (0.3-10 mm, matching fish size), the sudden pressure drop causes internal water vapor to expand rapidly, creating a porous, low-density structure (≤1 g/cm³)-the secret to the feed's ability to float for 12-24 hours. MIKIM's extruders use wear-resistant alloy screws and modular barrels to ensure consistent extrusion and long service life.

4. Precision Cutting & Post-Processing

A servo-controlled rotating cutter trims the extruded strands into pellets of uniform length (adjustable via PLC). The hot, moist pellets (25-30% moisture) are then conveyed to a continuous dryer (60-80°C) to reduce moisture to 10-12% (preventing mold growth). After drying, a counterflow cooler brings pellets to room temperature to avoid condensation and caking.

Optional post-processing steps include coating with fish oil or liquid vitamins (to enhance palatability and nutrient retention) and sieving to remove irregular pellets.

5. Quality Control & Packaging

Finished pellets undergo strict checks: floatability (ensuring they stay afloat for 12-24 hours), water stability (no disintegration), particle size uniformity, and nutrient content. Qualified feed is packaged in moisture-proof, sealed bags and stored in a cool, dry warehouse. MIKIM's machines integrate intelligent PLC controls to monitor temperature, pressure, and output in real time, ensuring consistent quality batch after batch.

 

 

 

 

 

MIKIM's fish feed pellet production lines and supporting machinery offer excellent value for money. Not only are they affordable, eliminating middlemen markups and allowing small and medium-sized enterprises (SMEs) and fish farmers to purchase complete sets of equipment at reasonable costs, but they also boast exceptional efficiency. The fully automated process, from raw material crushing and precise ingredient mixing to extrusion pelleting and maturation, is completed in one continuous flow. This results in high starch gelatinization rates and uniform pellet formation, significantly improving production efficiency and feed quality, truly achieving "low cost, high output." Choosing a MIKIM fish feed pellet production line means enjoying comprehensive pre-sales and after-sales service, including 24-hour online customer support, a one-year warranty on the entire machine, professional on-site installation, commissioning, and maintenance, and a stable supply of spare parts. Customers can buy with confidence and use with peace of mind, with both excellent value and service quality!
