Supporting Production Line
Raw Material Processing
Large raw materials are first crushed to≤10 mm, then ground into fine powder of 40–60 mesh. Automatic batching is performed based on preset formulas with a weighing accuracy of≤0.5%. The dual-shaft mixer blends the mixture for 5–10 minutes, achieving a uniformity of≥98%.
Mixing and Blending
After conditioning and pre-cooking with steam at 100–120°C, the material enters a dog treat extruder, where it is cooked and expanded under conditions of 120–180°C and 0.8–1.5 MPa. The product is extruded through quick-change dies and precisely cut into lengths of 3–15 mm.
Cooling and Screening
The product undergoes segmented temperature-controlled drying (moisture reduced below 10%), followed by air cooling to≤45°C. Nutritional ingredients are then vacuum-sprayed onto the pellets with a uniformity of≥95%. A vibrating screen removes impurities, resulting in a material loss rate of≤1.5%.
Finished Product Storage
Qualified pellets are automatically packed into bags of 1–25 kg (packing speed: 20–80 bags per minute). Automated palletizing reduces labor requirements to just 8–10 workers per shift, while production information can be traced via the PLC system.
RICHI equipment delivers reliable performance anywhere.

FAQs
Should you have any questions, RICHI will provide you with professional answers.
Is the quality of the finished dog food guaranteed? In what aspects is this reflected?
The product quality meets both domestic and international pet food production and quality inspection standards. The core advantages are reflected in three aspects: First, the diameter of the finished pellets can be freely adjusted between 0.6mm and 20mm, with uniform shape, consistent texture, and optimal expansion, achieving a breakage rate below 1.5%. Second, our dog food extruder for sale combined with steam conditioning ensures thorough material maturation and high starch gelatinization, making the food highly digestible for pets—digestibility is improved by over 20% compared to conventional equipment. Third, optimized drying and cooling processes result in final moisture content≤10%, excellent storage stability, strong oil absorption capacity, superior palatability, and outstanding market competitiveness.
Can the equipment handle high-meat formulations? What is the maximum percentage of fresh meat it can accommodate?
Yes, the equipment is equipped with specially designed screw components tailored for high-meat content recipes, enabling up to over 120% fresh meat inclusion. Our dog food extruder machine can easily produce high-protein premium dog food with exceptional formula compatibility, meeting the demands of premium pet food production. For example, in a high-end Russian project, the equipment successfully produced grain-free, low-allergenic dog food with more than 80% fresh meat content.
What types of pet-related products can the equipment produce? Besides dog food, can it make other products?
The dog treat extruder can mass-produce various dog food products, including complete adult dog food, puppy food, senior dog food, gastrointestinal care formulas, low-fat functional diets, puffed meat granules, and bone-shaped dental chews. Additionally, due to its high adaptability, minimal modifications allow seamless switching to cat food production (suitable for kittens, adult cats, and seniors, including grain-free, low-allergen formulas), floating fish feed, sinking shrimp feed, and feed for specialty economic animals such as foxes, minks, and rabbits, enabling multi-purpose use from a single machine.
