The extrusion function of fish feed production equipment perfectly meets the core quality requirements of pet food. The core of dog and cat food processing is to improve digestibility and palatability through extrusion. The high-temperature, high-pressure extrusion environment of fish feed pellet mills (temperature 120-150℃, pressure 3-5MPa) allows the starch in pet food ingredients to fully gelatinize (gelatinization rate over 85%) and the protein to moderately denature, improving digestibility. Simultaneously, the extrusion process enhances the natural aroma of the ingredients, making the feed more appealing. For example, when using a fish feed pellet mill to produce chicken and oat dog food, the protein digestibility reaches 88% after extrusion, far exceeding that of unextruded ordinary feed. The pellets are also soft and easy for dogs to chew, especially suitable for the digestive needs of puppies and senior dogs.
The core points for producing pet food using a small fish feed pellet making machine are parameter adjustment and formula adaptation. When producing dog food, the parameters are adjusted as follows: temperature 120-140℃, screw speed 300-350 rpm, die orifice diameter 3-5mm (adult dogs) or 1-2mm (puppies). The formula is mainly composed of grains (corn, oats) and meat (chicken breast, beef), with grains accounting for 30%-40% and meat accounting for 40%-50%, ensuring extrusion effect and nutritional balance. When producing cat food, due to higher protein requirements (60%-70%), the processing temperature needs to be increased to 130-150℃, and the pressure to 4-5MPa, extending the residence time of the raw materials in the extrusion chamber to ensure sufficient protein denaturation. The die orifice diameter is 2-4mm, and the formula is mainly composed of high-protein ingredients such as fish meal and chicken meal, with grains accounting for 15%-20%. For example, when producing salmon cat food, the proportions are 65% fish meal, 20% corn, 10% vegetable meal, and 5% fish oil. Processed according to the above parameters, the pellets have stable buoyancy, and the protein digestibility and absorption rate reaches 91%, meeting the standards of high-end cat food.
A practical case study validated the reliability of the floating fish feed making machine in producing pet food. A family owner who raises both koi and golden retrievers successfully implemented a dual-purpose machine using a small single-screw fish feed pellet mill by changing the die head and adjusting parameters. When producing koi feed, a 4mm die head was used at 130℃; when producing golden retriever food, a 3.5mm die head was used at 125℃ and a rotation speed of 320 rpm. Product testing showed that the dog food pellets' stability, water resistance, and nutritional indicators all met national pet food standards, and the production cost per kilogram of dog food was only 8-10 yuan, far lower than similar products on the market, significantly reducing breeding costs.
