Why Can Floating fish feed pellet extruder machines Produce Dog Food and Cat Food?

 

The core working principle of a floating fish feed extruder is exactly the same as that of a pet food extruder. Both process feed through a continuous process of "extrusion-heating-expansion-forming," which is the fundamental reason why they can produce feed for multiple product categories. Whether processing fish feed, dog food, or cat food, the raw materials are compressed under the push of the screw after entering the extruder, creating a high-pressure environment of 3-5 MPa inside the extrusion chamber. Simultaneously, the friction between the raw materials and the screw and chamber walls generates heat, which, combined with the equipment's built-in heating system, raises the temperature to a high temperature of 120-140℃. Under high temperature and pressure, the starch in the raw materials is fully gelatinized, the protein is moderately denatured, and the internal moisture is converted into supersaturated vapor. When the raw materials are ejected from the die, the pressure drops sharply, and the vapor expands instantaneously, forming a loose, porous structure inside the raw materials, ultimately shaping them into pelleted feed. This process improves the digestibility and absorption rate of the feed and kills harmful microorganisms in the raw materials, making it suitable for processing feed for fish, dogs, cats, and other animals.

 

The extrusion function of automatic fish food making equipment plays a highly complementary role in improving the quality of pet food as it does with fish feed. For dog food, the extruded pellets are soft and easy for dogs to chew and digest, making them especially suitable for puppies and senior dogs. Simultaneously, the extrusion process enhances the natural aroma of the raw materials, increasing dogs' appetite. For cat food, which has a high protein content (60%-70%), the high-temperature, high-pressure environment of the fish feed extruder allows for thorough protein denaturation, improving protein utilization. Furthermore, the extruded pellets have a moderate density, suitable for cats' eating habits. For example, when processing chicken and oat dog food using a fish feed extruder, the starch gelatinization rate reaches over 85% after extrusion, and the protein digestibility and absorption rate increases by 20%-30%, with minimal difference in quality compared to products produced by dedicated pet food extruders.

 

It is important to note that the core extrusion components (screw, extrusion chamber, die) of the small fish feed maker machine share the same design logic as the small dry dog ​​food making machine, both prioritizing precise control of the high-temperature, high-pressure environment. The screw's three-section structure (feeding section, compression section, and extrusion section) ensures sufficient compression and extrusion of the raw materials, while the sealed design of the extrusion chamber maintains stable pressure. The versatility of these components further validates the feasibility of cross-category production. Whether it's fish feed or pet food, the core requirements for extrusion effect (sufficient cooking and stable pellets) are exactly the same, allowing fish feed extruders to be adapted for pet food production without significant modifications.

 

 

 

 

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."
