Core particle size range: 0.8mm-10mm, covering all age groups of fish
A high-quality twin screw sinking fish feed making machine can produce fish feed with a particle size range of 0.8mm-10mm. By changing the die head with different aperture sizes and adjusting the screw speed and feed rate, stepless adaptation can be achieved to meet the needs of fish of all ages, from juveniles to adults. Specifically, 0.8mm-1.5mm is the micro-particle size, suitable for fry and juvenile fish (such as carp fry and grass carp fry); 2mm-3mm is the small particle size, suitable for juvenile fish (3-5cm in length); 4mm-6mm is the medium particle size, suitable for medium-sized fish (5-10cm in length); and 7mm-10mm is the large particle size, suitable for adult fish (over 10cm in length). Some large twin screw extruders can be customized to produce 12mm large particle sizes, suitable for large ornamental fish or commercially valuable fish such as sharks and koi.
Particle Size Adjustment Techniques: Linking Extruder Parameters for Precise Forming
The core of particle size adjustment for the Twin-Screw Sinking Fish Feed Extruder lies in "die selection + parameter linkage," both of which are indispensable. First, select a die with a corresponding aperture size based on the target particle size. The die aperture should be slightly smaller than the target particle size (to allow for expansion space). For example, to produce 2mm fish feed, choose a 1.8mm aperture die. Second, adjust the extruder parameters: for smaller particle sizes, reduce screw speed (300-320 rpm), increase temperature (120-130℃), and reduce feed rate to ensure thorough cooking and fine forming; for larger particle sizes, increase screw speed (350-380 rpm), decrease temperature (140-150℃), and increase feed rate to ensure compact particles that are less prone to breakage. Actual test data shows that when parameters are precisely adjusted, the particle size error can be controlled within ±0.2mm, meeting industry standards.
Authoritative Adaptation Recommendations: Precisely Match Particle Size Based on Fish Species
Targeted Adaptation Recommendations: For small omnivorous fish (such as minnows and mosquitofish), a small particle size of 1mm-2mm is suitable; for common commercial fish (carp, grass carp, tilapia), 2mm-3mm for juveniles, 4mm-5mm for medium-sized fish, and 6mm-8mm for adults; for carnivorous fish (bass, snakehead), a medium to large particle size of 3mm-7mm is suitable, with increased particle hardness; for ornamental fish (goldfish, tropical fish), a particle size of 0.8mm-2mm or small is suitable, and irregularly shaped particles such as round and strip-shaped particles can be customized. Furthermore, the Twin Screw Small Fish Food Pellet Making Machine allows for flexible switching of particle size specifications according to user needs without requiring additional replacement of core components, improving production flexibility.
