What Raw Materials Are Used in small fish feed pellet extruder?

 

Fishmeal is a high-quality protein raw material for producing floating fish pellets, perfectly suited to the extrusion function of small fish food making machines. With a protein content as high as 60%-70%, fishmeal boasts a complete amino acid composition, meeting the growth needs of various fish species, especially carnivorous fish. Under the high temperature and pressure environment of the extruder, the proteins in fishmeal undergo moderate denaturation, destroying anti-nutritional factors and improving digestibility and absorption. Simultaneously, its viscosity enhances pellet cohesion, preventing disintegration in water. High-quality fishmeal has low ash content (≤18%) and moisture content (≤10%), making it suitable for direct use in extrusion processing. The proportion should be adjusted according to the fish species: 40%-50% for carnivorous fish (such as bass and mandarin fish), and 20%-30% for omnivorous fish (such as carp and tilapia).

Soybean meal is a cost-effective plant-based protein raw material, perfectly suited to the production needs of fish pellet making machines. With a protein content of 40%-48%, soybean meal is widely available and inexpensive, making it the preferred plant-based protein raw material for small-scale fish farmers. In the extrusion environment of an extruder, anti-nutritional factors such as trypsin inhibitors in soybean meal are destroyed, increasing protein digestibility from 60% to over 85%. Simultaneously, it forms a stable network structure with starch, enhancing particle buoyancy. When using soybean meal, it should be ground to at least 80 mesh to avoid large particles affecting the extrusion effect, with the proportion controlled at 20%-30%.

 

Animal by-products (such as chicken meal and meat and bone meal) are high-quality protein supplements that improve feed palatability. Chicken meal has a protein content of 55%-65%, moderate fat content, and a delicate texture. After extrusion in a floating fish feed extruder, its natural aroma is enhanced, increasing fish's feeding activity. Meat and bone meal has a protein content of 40%-50% and is rich in minerals, supplementing the calcium, phosphorus, and other elements needed for fish growth. These raw materials should be selected from products produced by reputable manufacturers to ensure they are free from spoilage and off-odors, with moisture content controlled below 10%, accounting for 5%-15%. For example, when producing tilapia floating feed, adding 10% chicken meal, along with fish meal and soybean meal, and then extruding it through an extruder, significantly improves the palatability of the feed, speeds up the tilapia's feeding, reduces leftover feed, and increases the feed conversion rate by more than 15%.

 

 

 

 

 

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!!!
