Cat Kibble Extrusion Line: Crafting Premium Puffed Diets

Driven by innovative technology, a new high-nutrition, complete cat food extrusion line is leading a new trend in pet food.

With the global trend toward pet humanization, pet owners are demanding higher-than-ever standards for the nutrition, safety, and quality of their staple food. To meet this market demand, Shandong Arrow Machinery has launched a new generation of high-nutrition, complete cat food extrusion lines. This line integrates cutting-edge extrusion technology, a precise nutrient retention system, and intelligent control to produce high-end extruded dry food that meets the nutritional needs of cats throughout their life cycle.

Scientific formulation and raw material pretreatment: The cornerstone of nutrition

The cat food production line begins with an efficient raw material receiving and pretreatment system. Fresh meat, poultry, or fish first undergoes a crushing and grinding process to create a uniform minced meat, ensuring high-quality and easily digestible protein. At the same time, dry ingredients such as grains and dietary fiber are precisely measured and mixed with the minced meat. Vital vitamins, taurine, minerals, and other micronutrients are added post-process through an advanced premixing system, effectively avoiding early losses during high-temperature processing and ensuring the complete nutritional value of the finished product.

Twin-screw Extrusion: Core Technology Unlocks High Nutritional Density

The core of the cat food production line is the advanced twin-screw extruder. This process achieves multiple goals:

Cooking and Sterilization: The high-temperature and high-pressure environment thoroughly cooks starch and denatures proteins, effectively killing harmful microorganisms such as Salmonella, ensuring product biosafety.

Precision Shaping: Customized molds are used to produce pellets of various shapes, sizes, and densities to suit the feeding preferences of different groups, including kittens, adult cats, and indoor cats.

Nutrient Retention: Modern twin-screw technology allows for the production of pellets in a single, precise, and precise manner. The equipment incorporates multiple processing zones (such as steaming, shearing, and homogenizing) to maximize the preservation of heat-sensitive nutrients through precise process control.

Drying and Cooling: Ultimate Palatability and Shelf Life

The puffed pellets enter a multi-layer dryer and cooler, reducing their moisture content to safe levels, ensuring a crispy texture and long-term storage stability. Subsequently, a vacuum coater or flavor sprayer evenly coats each pellet with a high-temperature fresh meat slurry, natural attractants, oils, and additional nutrients. This step significantly enhances the ultimate palatability and energy density of the cat food, ensuring a satisfying appetite for your cat.

Automated Packaging and Quality Control

Finally, the finished cat food is metered, filled, and sealed on an automated packaging line, using nitrogen-filled freshness technology to lock in flavor and prevent oxidation and spoilage. The entire production line is controlled by a Centrally Integrated Process Control (CIP) system. We monitor and control every step of the process, from raw materials to finished product, to ensure stability, efficiency, and traceability, meeting the most stringent pet food production regulations.
