Full‑Automatic Pet Feed Extrusion Production Line｜One‑stop Complete‑set Equipment Solution For Dog & Cat Kibble Processing

I. Complete Pet‑feed Production Technological Process: Full‑link Automation from Raw‑material Mixing to Finished‑product Packaging
The complete pet‑feed extrusion production line realizes finished dog and cat kibble directly from powder raw materials. Each process is automatically connected to minimize manual intervention and meet the requirements of industrial mass production. Core working procedures include powder mixing, closed conveying, twin‑screw extrusion puffing, cutting & forming, baking & drying, air cooling, oil‑spraying seasoning and finished‑product packaging.
Powder‑mixing Process: The automatic powder‑mixing equipment accurately proportions corn flour, meat meal, fish meal, various grains, vitamin additives according to pet‑feed formulas, together with water and oil liquid addition systems for high‑speed stirring and blending. Mixed materials feature uniform humidity with fully integrated nutritional components without agglomeration. High mixing uniformity lays a solid foundation for subsequent extrusion and guarantees balanced and stable nutrition for each batch of pet feed.
Closed Conveying Process: Mixed raw materials are delivered to the extruder host via closed screw conveyors. The closed‑structure prevents dust leakage and raw‑material spillage loss, complying with food‑grade safety production standards. Continuous and stable quantitative feeding ensures non‑stop operation of the whole production line.
Twin‑screw Extrusion Process (Core of the Production Line): Under combined conditions of high temperature, high pressure and high shear force inside the twin‑screw extruder, materials complete starch gelatinization and protein denaturation & maturation for full melting and puffing. Operators can precisely adjust parameters of temperature, pressure and screw speed to adapt to diverse formulas including high‑protein and standard pet food. By replacing molds of different specifications, various shapes such as round, bone‑shaped, heart‑shaped and special‑shaped dog & cat kibble can be produced. The porous inner structure of pellets improves nutrient digestibility for pets.
Cutting & Forming Process: Extruded materials are cut to fixed lengths by high‑speed rotary cutters, delivering evenly‑sized pellets with neat cutting edges and few fragments. Cutting speed is interlocked and adjusted synchronously with host capacity to flexibly produce different pellet sizes for puppy food, adult‑dog food, kitten food and other specifications.
Baking & Drying Process: Newly‑extruded semi‑finished pellets carry high moisture content and enter the multi‑layer continuous baking dryer. Gradient constant‑temperature hot‑air drying evenly removes excess internal moisture and controls final moisture within the safe range of 8‑10 %. It effectively inhibits mould growth, greatly extends pet‑feed shelf life, avoids uneven dampness or partial scorching of pellets and ensures qualified pellet hardness.
Air‑cooling Process: High‑temperature dried pet‑feed pellets are transported to the air‑cooling conveyor line. Circulating ambient air dissipates heat evenly and quickly cools pellets down to room temperature. Cooled pellets become dry, hard and anti‑moisture‑reabsorption, well prepared for subsequent oil spraying and packaging. It prevents product deterioration caused by water‑vapor condensation inside packaging bags and improves the finished‑product qualification rate.
Oil‑spraying & Seasoning Process: Cooled pellets go into the spraying system. Animal fat and palatability enhancers can be evenly sprayed on pellet surfaces to improve food palatability and satisfy production requirements of various formulas for cat and dog food.
Finished‑product Packaging Process: Processed pet‑feed pellets connect with automatic packaging equipment for weighing, bag‑filling and sealing to output bagged final products. Full‑automatic production is realized from powder raw materials to bagged pet food.

II. Core Equipment Advantages: Intelligent & Stable, Solving Mass‑production Pain Points of Pet‑feed Factories
The new‑generation complete pet‑feed extrusion line is iteratively upgraded targeting real‑world production pain points of domestic and overseas feed factories. It addresses industry challenges including unstable extrusion performance, poor pellet appearance, weak formula adaptability, high energy consumption and complicated operation. Five core strengths are achieved: strong formula compatibility, high‑level automation, high finished‑product yield, easy maintenance and controllable energy consumption.
Host screws and barrels are made of high‑wear‑resistant alloy materials with high‑temperature and shear resistance, supporting 24‑hour non‑stop factory production and extending service life to lower later‑stage spare‑part replacement costs. The complete line is equipped with a PLC variable‑frequency intelligent control system and visual human‑machine interface. Parameters including temperature, rotating speed and conveying speed can be set with one‑click and precisely fine‑tuned. Overseas operators can get proficient after simple training, reducing reliance on senior technicians.
Closed‑loop regulation of process parameters guarantees highly‑consistent puffing degree, maturation level and moisture content among batches, achieving over 99 % finished‑product qualification rate and minimizing raw‑material loss. Featuring strong compatibility, the equipment can produce both ordinary grain‑based dog & cat food and high‑protein fresh‑meat pet formulas. New product iterations can be realized merely by replacing molds and adjusting parameters. All material‑contact components of the whole machine adopt food‑grade stainless‑steel materials for easy disassembly and cleaning to meet pet‑food hygiene audit standards. The drying unit adopts thermal‑insulation structures for remarkably reduced comprehensive energy consumption and long‑term production‑cost control for factories.

III. Source‑factory Strength: Self‑developed & Self‑manufactured to Secure Order Delivery for Global Clients
Our company is a source manufacturer of pet‑feed extrusion machinery integrating R&D, structural design, complete‑machine production, foreign‑trade sales and technical services without markup from intermediaries, delivering prominent cost‑performance under identical configurations. We own standardized industrial workshops, a full set of precision‑processing machine tools and complete workshops for component processing and complete‑machine assembly.
