What is a Twin-Screw Twin screw fish feed making machine?

 

Core Definition: Extrusion Equipment for Dedicated Floating Feed

The Twin Screw Fish Feed Extruder Machine is an automated device integrating raw material extrusion, cooking, expansion, and forming. Its core features include a meshing twin-screw structure and a precise temperature and pressure control system. Specifically designed for producing fish feed with a buoyancy rate of ≥95%, it can process pellets that float stably in water for 4-6 hours without disintegrating. The equipment is compatible with various raw materials such as fishmeal, cornmeal, and soybean meal, meeting the feed needs of mid-to-upper-level fish such as bass, tilapia, and koi. It is widely used in aquaculture farms and feed processing plants.

 

Working Principle: Twin-Screw Synergistic Extrusion Mechanism
After the Twin-Screw floating fish feed extruder machine starts, the pre-treated raw material enters the twin-screw extrusion chamber at a uniform speed. The meshing twin screws rotate at high speed (300-380 r/min), generating strong shearing, extrusion, and mixing effects on the material. Simultaneously, the built-in steam heating system creates a high-temperature environment of 120-160℃ and a high-pressure environment of 4-6 MPa within the chamber. This causes rapid gelatinization of starch and denaturation of proteins in the raw material, while water is converted into superheated steam. The pressure drops sharply the moment the material is extruded from the die, and the steam rapidly expands and escapes, creating a porous structure inside the pellets, thus achieving the floating characteristic and simultaneously completing pelletizing.

Differences from ordinary extruders: Upgraded buoyancy adaptation
Compared to single-screw extruders, the Twin Screw Sinking Fish Feed Making Machine uses twin screws for coordinated extrusion, resulting in more thorough material maturation and more uniform force distribution, significantly improving buoyancy and particle stability. A precise temperature and pressure control system allows for flexible adjustment of the degree of extrusion, preventing over-expansion and particle breakage. Simultaneously, it offers stronger feeding stability, reducing the likelihood of clogging and enabling continuous production of high-quality floating feed, solving the problems of large buoyancy fluctuations and uneven particle size in ordinary extruders.

 

 

 

 

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!!!
