As the global pet economy surpasses US$300 billion, the pet food industry is undergoing a consumption upgrade—from simply “having enough to eat” to “eating well.” In this process, advanced equipment not only serves as the cornerstone of quality assurance but also plays a critical role in helping companies build their core competitiveness. This article will take RONSY Ail Pet Food, one of the top ten feed manufacturers nationwide, as its starting point to reveal the top equipment used throughout the entire pet food production chain and shed light on how technological innovation is driving industry transformation.

Behind each form of pet staple food—such as the crispy granules of extruded food, the natural aroma of baked food, and the complete nutrition of freeze-dried food—lies the precise collaboration of equipment and processing techniques. The fundamental differences among various staple foods essentially reflect the direct manifestation of the technical characteristics of the production equipment in the final product.

Puffing Equipment: U.S. WENGER 5T/10T Puffing Unit

RONSY pet food production lines—comprising two units from the U.S.-based WENGER, a world-leading extrusion and puffing equipment manufacturer—have capacities of 10 tons and 5 tons respectively. The U.S. WENGER has redefined the versatility of steaming and puffing machines, achieving maximum power output with a smaller footprint and leveraging higher SME (specific mechanical energy) to enhance production precision. The extruded pellets boast a distinctive aroma and a loose, porous structure, making them highly palatable. Moreover, some of the proteins in the pellets are converted into short-chain structures, facilitating easier digestion and absorption by pets. These machines represent cutting-edge equipment for producing extruded pet foods. As the dominant type of pet food currently accounting for over 70% of the market, extruded pet food offers comprehensive nutrition and cost-effectiveness—key priorities for pet owners.

The two meshing screws in the WENGER10T extrusion unit enable raw materials to undergo starch gelatinization and protein denaturation within 5–20 seconds, resulting in a loose, porous particle structure and partially converting some proteins into short-chain peptides. This equipment features a direct-injection technology for fresh meat, allowing fresh meat to be emulsified into a slurry at 50°C without prior processing. The feed production process involves only one high-temperature stage, preserving nutrients with higher bioavailability and better utilization, thereby enhancing pets’ digestion and absorption and ensuring more efficient nutrient assimilation. At the same time, the high-temperature sterilization effectively eliminates pathogenic bacteria such as Salmonella, while maintaining a shelf life of 6–12 months at room temperature, making it ideal for long-term storage.

Low-temperature emulsifier: German KARLSCHNELL ultrafine pulverizer

RONSY pet food also features Europe's top-of-the-line German KARLSCHNELL ultrafine pulverizer. Building on Germany's superb grinding technology, the KARLSCHNELL pulverizer boasts exceptional crushing capabilities, enabling ultrafine grinding with ease. Based on the performance of similar German equipment, its grinding fineness easily surpasses 200 mesh, allowing it to grind a wide variety of materials—including grains, meats, legumes, and even pharmaceutical raw materials—into a uniformly fine and smooth consistency. In pet food production, this ensures precise fulfillment of diverse fineness requirements. Moreover, the equipment exhibits remarkable adaptability and versatility, supporting multiple grinding methods such as dry and wet processes. It can be flexibly adjusted according to different material characteristics and production processes, effortlessly handling a wide range of processing scenarios. Additionally, equipped with interchangeable processing modules, the machine not only performs core crushing functions but also offers supplementary capabilities like dispersion, homogenization, and emulsification. With just one piece of equipment, multiple production steps can be accomplished in succession, effectively reducing production time and inhibiting bacterial growth.

During the production process, fresh ingredients are subjected to ultra-high-speed shear emulsification at temperatures as low as -25℃. This approach not only controls temperature rise during production—thus preventing microbial growth—but also achieves an unparalleled level of ingredient fineness. Such fine texture reduces the digestive burden on pets and enhances their nutrient absorption efficiency. KARLSCHNELL’s low-temperature freshness-locking technology is widely adopted in the premium pet food market for baked products. Its key advantage lies in the low-temperature environment, which minimizes heat-sensitive nutrient loss. As a result, proteins, amino acids, and vitamins are retained at rates 15% to 20% higher than in extruded foods, ensuring more complete nutritional preservation—particularly beneficial for pets with high protein requirements, such as athletic dogs and pregnant pets. Moreover, this low-temperature process avoids the hard, brittle texture typically associated with high-temperature extrusion; the kibble remains crisp yet tender, closely mimicking the texture of “homemade food.” This results in superior palatability compared to extruded foods, making it highly appealing even to picky eaters and offering a more “natural” eating experience. The low-temperature process places stringent demands on the freshness of raw materials—poor-quality ingredients tend to develop off-flavors during baking. Consequently, most baked pet foods emphasize a high “fresh meat content” (often exceeding 60% fresh meat addition) and minimize the use of fillers like grains. This ensures greater transparency in ingredient sourcing and delivers products that are more reassuring in terms of quality and safety.

Spraying: Dutch DINNISSEN vacuum spraying machine

The RONSY pet food, equipped with DINNISSEN vacuum sprayers, utilizes advanced vacuum spraying technology. Through these vacuum sprayers, the pet food can fully incorporate all the fats and oils it needs. The adjustable vacuum ensures that liquids penetrate deeply into the pellets without leaving them feeling sticky or greasy on the surface. An active mixing zone is created between the two paddle shafts, where oil- and water-based substances are sprayed onto the pellets. Thanks to the mixing action in this active zone, each pellet receives an equal amount of liquid. This process not only effectively preserves functional ingredients such as vitamins and minerals but also keeps the pellets fresh and consistent in texture both inside and out, thereby enhancing the palatability of the pet food.

Drying & Cooling: Geelen Dryer & Cooling Tower from the Netherlands

RONSY Ail Pet Food owns

Geelen drying and cooling equipment has revolutionized the way pet food and aquaculture feed are dried. GEELEN’s thermodynamic and aerodynamic design software, which has been extensively validated in the German market over many years, ensures that GEELEN dryers can achieve uniform moisture content in every individual particle. The cooling system employs a highly efficient heat exchanger and uses filtered air for both cooling and drying. As a result, the finished pellets remain intact with minimal dust and debris, effectively reducing cross-contamination. Equipped with an advanced automatic control system, the dryer can precisely regulate the drying process according to product-specific process parameters such as air flow rate, air temperature, and residence time, ensuring that the moisture content of the final product remains consistently within ±0.5%.

Automatic filling: German BOSCH packaging machine

RONSY’s Ai’er pet food also features BOSCH packaging machines, which can fully automate tasks such as filling, nitrogen flushing for freshness preservation, and sealing. The entire machine incorporates core German packaging technology. By filling the packaging bags with nitrogen to reduce oxygen levels, the product’s shelf life is effectively extended. Throughout the entire process, light is completely blocked to isolate ultraviolet rays, thereby effectively preventing oxidation reactions and ensuring that the product retains its freshness and nutritional value without any loss.
