In the backdrop of the thriving modern pet economy, the demand for pet food is increasing, driving innovations in production technology. Fully automated pet food production lines, as efficient and intelligent manufacturing systems, can achieve one-stop production from raw material mixing, extrusion shaping, drying and seasoning to finished packaging, meeting market demands for diverse products such as dog food, cat food, and fish feed. Their core advantages lie in high levels of automation, precise nutritional ratios, and the ability to flexibly adjust product forms and flavors, making them a popular choice in the pet food processing industry.

Full-process automation, enhancing production efficiency

This automatic pet food production line integrates various advanced equipment, including a flour mixer, twin-screw extruder, air conveyor, dryer, seasoning line, and cooling conveyor, forming a seamless production process. First, raw materials are evenly mixed in the mixer to ensure that nutrients such as protein, vitamins, and minerals are fully integrated; then, the twin-screw extruder uses high temperature and pressure to puff the raw materials, creating a porous structure that enhances palatability and improves digestibility. The extruded product is conveyed by air flow to the drying stage to remove excess moisture and extend shelf life, and finally, flavoring agents are added through a spraying seasoning system before cooling and packaging. The entire process requires no manual intervention, significantly reducing production costs and error rates.

Scientific formulation, balancing nutrition and palatability. 

The core raw material of the production line is highly expanded cornstarch, which forms a loose texture during processing, suitable for pets to chew. Additionally, the formula can be flexibly adjusted based on different pet needs: for example, adding bone meal and meat protein to meet dogs' requirement for animal-based nutrition, increasing fish components to enhance the attractiveness of cat food, or mixing plant fibers to promote intestinal health. Moreover, by adjusting the extrusion molds, various shapes such as pellets, strips, and cartoon designs can be produced, enhancing product differentiation and competitiveness.

This production line is widely applicable and aids in industry upgrades.

 It is suitable not only for common dog and cat food but can also be extended to aquafeed (such as ornamental fish food) or specialty pet food (such as bird and reptile feed). Its modular design allows companies to flexibly expand according to production capacity needs, while also meeting international food safety standards. For small and medium-sized manufacturers, investing in such automated equipment can quickly achieve large-scale production; for large enterprises, it can optimize the supply chain and capture the high-end market with its high stability.

The fully automated pet food production line, through technological innovation, integrates nutritional science, smart manufacturing, and market demand to provide efficient and reliable solutions for the industry. As pet consumption trends towards refinement and personalization, production lines with multifunctional and customizable features will become key to enhancing corporate competitiveness. In the future, further integration of intelligent monitoring and big data analysis technologies may open up broader development prospects for the pet food industry.

Intelligent processing from raw materials to finished products
Flour mixer → Twin screw extruder → Air conveyor → Dryer → Seasoning machine → Cooler

Flour Mixer : mixing raw materials(corn flour, bone meal, meat, protein, vitamins,etc)

Screw Conveyor : conveying the materials

Double Screw Extruder : cooking the raw material and extruding different shapes by placing different molds

Air Conveyor : conveying the extruded products

Dryer : baking the products

Flavoring Machine : Spray seasoning oil and powder onto the food

Cooler: cooling

1. Raw Material Mixing: Precise Formulation for Balanced Nutrition

The flour mixer is the first step in the production line, responsible for thoroughly blending various raw materials to ensure uniform nutrient distribution. Main ingredients include corn flour, bone meal, meat, protein, vitamins, and minerals, which can be adjusted according to the nutritional needs of different pets (such as dogs, cats, and fish). The mixer uses high-speed stirring technology to fully integrate powdery, granular, and liquid ingredients, preventing clumping and ensuring stability in the subsequent extrusion process.

2. Material Conveying: Efficient Transport with Minimal Manual Intervention

The mixed materials are smoothly transported to the double screw extruder via a screw conveyor. This equipment adopts a closed design to prevent contamination, while the conveying speed can be adjusted according to production needs, ensuring uniform feeding into the extruder and improving production efficiency.

3. Extrusion and Expansion: High-Temperature, High-Pressure Shaping for Diverse Forms

The double screw extruder is the core equipment of the automatic pet food production line. Through high temperature and pressure, it gelatinizes starch and denatures protein, allowing the material to expand and take shape during extrusion. By replacing different molds, a variety of pet food shapes can be produced, such as granules, strips, bone shapes, and fish shapes, catering to the feeding preferences of different pets. The high-temperature process also effectively sterilizes the product, enhancing food safety.

4. Air Conveying: Rapid Transfer While Maintaining Product Integrity

The extruded products are transported to the dryer by an air conveyor. This equipment uses low-pressure airflow to prevent breakage and minimizes mechanical contact, ensuring the integrity of the fragile expanded products.

5. Drying Process: Moisture Removal for Extended Shelf Life The dryer employs hot air circulation technology to evenly remove excess moisture from the food, achieving an optimal moisture content (typically 8%-10%) to prevent mold and extend shelf life. Temperature and drying time can be precisely controlled to ensure a crispy texture while preserving nutritional value.

6. Flavor Coating: Enhancing Palatability to Boost Pet Appetite

The flavoring machine evenly sprays seasoning oils, meat slurries, and nutritional additives onto the food surface to enhance flavor. The spray volume can be adjusted to meet different taste requirements, such as beef, fish, or chicken flavors, improving pets' acceptance of the food.

7. Cooling Treatment: Stabilizing Quality for Packaging

Finally, the products enter the cooler, where natural or cooled air circulation reduces the temperature to prevent moisture absorption due to residual heat, ensuring stability and crispness before packaging. The cooled pet food can then proceed directly to automatic packaging machines for final sealing.
