Where are single screw floating fish feed extruder machines used?

 

Fish fry starter feed production: Utilizing the principle of fine extrusion molding to meet the feeding needs of fry. Fish fry are small in size and have narrow mouths, requiring fine-particle feed (less than 1mm) that is easily digestible and highly water-resistant. The single-screw fish feed processing machine uses a small-diameter die (0.8-1mm) and reduces the screw speed (200-250r/min) to minimize the residence time of the raw material in the extrusion chamber, controlling the degree of puffing and producing fine, soft, and fluffy feed particles. During the compression and melting stage, precise control of temperature (100-110℃) and pressure (2-3MPa) ensures that the raw material is fully melted but not over-expanded, preventing the particles from being too hard and making it difficult for fry to eat. Simultaneously, the extrusion puffing principle fully gelatinizes the starch in the raw material, improving feed digestibility and reducing the incidence of gastrointestinal diseases in fry. For example, when producing starter feed for carp fry, a single-screw extruder, through parameter adjustments, can produce fine pellets of 0.8mm with a water resistance of over 6 hours, perfectly suited to the feeding and digestive needs of fry.

 

Adult fish fattening feed production: Utilizing efficient extrusion principles to improve feed utilization. Adult fish grow rapidly, have high energy and protein requirements, and need standard 3-5mm pellets. By increasing the screw speed (300-350 r/min), enlarging the die orifice diameter (3-5mm), and increasing the extrusion chamber temperature (120-140℃) and pressure (3-5 MPa), the extrusion effect is enhanced, creating a porous and loose feed structure, improving palatability and digestibility. During the raw material delivery stage, adjusting the helix angle improves delivery efficiency, ensuring production capacity meets the needs of large-scale adult fish farming. For example, in the production of grass carp feed, a single-screw extruder fully expands raw materials such as corn, soybean meal, and wheat bran to produce 4mm sinking pellets. This increases the digestibility and absorption rate by more than 25% compared to powdered feed, and reduces the feed conversion ratio to below 1.5, significantly improving aquaculture efficiency.

 

Specialty fish feed production: Utilizing controlled extrusion principles to match specific feeding habits. Specialty fish (such as bass and grouper) are mostly carnivorous, prefer floating feed, and have high requirements for protein content and palatability. A single-screw fish feed making machine precisely controls extrusion parameters, allowing the feed to fully expand under high temperature and pressure, forming stable, floating pellets (floating time reaches 8-12 hours). In terms of raw material selection, a formula with high fishmeal content is used. Through the compression and melting principle of the single screw, the protein in the fishmeal is fully denatured, improving digestibility and absorption. Simultaneously, by adjusting the die shape, irregular pellets are produced, enhancing the palatability of the feed. For example, in the production of sea bass feed, a single-screw extruder expands raw materials such as fishmeal, soybean meal, and fish oil at 130-140℃ and 4-5MPa to produce 3mm floating pellet feed with a protein content of over 40%, perfectly suited to the carnivorous needs and surface-feeding habits of sea bass.

 

Summary of Application Advantages: High cost-effectiveness and flexibility based on its operating principle. The working principle of the single-screw fish feed extruder gives it a significant cost-effectiveness advantage in aquaculture feed production. Its low equipment purchase and operating costs make it suitable for small and medium-sized aquaculture farms. Furthermore, by adjusting parameters such as screw speed, temperature, pressure, and die orifice diameter, different types and specifications of aquaculture feed can be flexibly produced to meet the farming needs of various fish species. This characteristic makes it one of the mainstream equipment in the aquaculture feed processing field, especially favored by family aquaculture farmers and small fish farms.
