What are the steps in making fish feed with the small floating fish feed machine?

Making fish feed with fish food pellet machine involves a systematic process to ensure nutritional balance, palatability, and suitability for target fish species. Below are the core steps, applicable to both floating and sinking feed production:

1. Raw Material Preparation & Formulation
First, design a formula based on fish species (carnivorous/omnivorous/herbivorous) and growth stage (larvae/juvenile/adult). Key ingredients include protein sources (fish meal, soybean meal), energy sources (corn flour, wheat bran), fats (fish oil), vitamins, and minerals. 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 uniformity.
2. Conditioning
The mixed powder is fed into a conditioner, where steam or water is added to adjust moisture (16-18%) and temperature (85-95°C). This step promotes starch gelatinization, softens the material, and enhances subsequent extrusion efficiency. Conditioning time lasts 2-5 minutes to ensure even heat and moisture distribution.
3. Extrusion/Compression Molding
For floating feed: Use a small fish food pellet making machine (single/twin-screw) to apply high temperature (110-130°C), pressure (3-10 MPa), and shear force. The material expands through die holes due to sudden pressure drop, forming a porous structure (density ≤1 g/cm³) for buoyancy.
For sinking feed: Use a pellet mill to compress the material directly through a ring die, producing dense pellets (density >1 g/cm³) without expansion.
A rotating cutter trims pellets to the desired length (0.3-10 mm) based on fish size.
4. Drying & Cooling
Extruded/compressed pellets have 25-30% moisture, requiring drying in a belt or fluidized bed dryer (60-80°C) to reduce moisture to 10-12% (prevents mold). After drying, pellets are cooled to room temperature via a counterflow cooler to avoid condensation and caking.
5. Post-Processing & Quality Control
Optional coating (fish oil, amino acids) enhances palatability and nutrient retention. Quality checks include floating stability (12-24 hours for floating feed), hardness, and nutrient analysis. Qualified feed is packaged in moisture-proof bags and stored in a cool, dry warehouse.
Each step is critical to ensuring feed digestibility, safety, and adaptability to fish feeding habits, supporting efficient aquaculture.

 

 

 

 

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!
