How to choose the right fish feed pellet extruder for different scenarios?

Single-screw fish feed pellet extruders are the mainstream choice for small-scale aquaculture. Their core features are simple structure, low investment cost (equipment with an hourly capacity of less than 1 ton costs approximately 100,000-200,000 RMB), and easy operation. This type of equipment uses a screw and barrel working together, with the rotation of a single screw achieving the extrusion and conveying of raw materials. It is suitable for family farms or small feed mills for producing feed for common fish such as grass carp, crucian carp, and koi. Its disadvantages include relatively poor mixing and extrusion uniformity, making it unsuitable for producing specialty aquatic feeds with extremely high quality requirements, and a relatively low hourly capacity (typically 0.2-1 ton/hour), which cannot meet the needs of large-scale production. A family koi farm using a single-screw extruder produces feed pellets that are uniform in size and withstand water for up to 30 minutes, fully meeting its own aquaculture needs.

 

Twin-screw fish feed pellet extruders are the preferred choice for medium to large-scale aquatic feed production. They employ two interlocking screws, subjecting the raw materials to stronger shearing, mixing, and extrusion within the barrel, significantly improving extrusion uniformity and achieving a starch gelatinization rate of over 95%. These types of equipment have high capacity (1-5 tons/hour) and can be adapted to various raw materials such as fishmeal, algae, and grains. They can produce specialty aquatic feeds for sea bass, grouper, and shrimp, with equipment prices ranging from approximately 300,000 to 800,000 yuan. A medium-sized shrimp feed mill in Guangdong Province, after adopting a twin-screw extruder, saw its feed protein digestibility increase to 85%, and shrimp growth rate and survival rate significantly improved. The disadvantages of twin-screw extruders are their complex structure, relatively high maintenance costs, and the need for specialized operators.

 

Depending on the heating method, fish feed pellet extruders can also be divided into electric heating and steam heating types. Electric heating models are easy to install, do not require a steam boiler, and are suitable for small-scale applications with stable power supply. Steam heating models have high heating efficiency, more precise temperature control, and lower energy costs, making them suitable for medium to large-scale production lines, but require additional steam generation equipment.

 

Compared to the small pellet mills commonly used in cat and dog pet food production, the selection of fish feed pellet extruders focuses more on production capacity and extrusion effect, while pet food equipment emphasizes flexibility and nutrient retention. When selecting a model, it is necessary to differentiate based on the core needs of the feeding target.

 

 

 

 

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!
