Low-temperature extrusion technology is crucial for nutrient retention; therefore, an extruder with steam preheating and low-temperature extrusion functions must be selected. Taurine, probiotics, and Omega-3 in pet food are easily deactivated at high temperatures. The barrel temperature of a floating fish feed making machine needs to be precisely controlled between 85-95℃. This requires the equipment to be equipped with an infrared thermometer and an automatic temperature control system to adjust the heating power in real time, with temperature fluctuations ≤ ±0.5℃. Compared to traditional electrically heated extruders, steam-heated equipment offers more uniform temperature and can improve nutrient retention by more than 25%, making it particularly suitable for producing high-end pet food.

The texture and forming effect depend on the equipment's shearing and forming system. Cats and dogs have preferences for feed hardness and pellet shape. Small dog food requires a pellet diameter of 3-5mm and a hardness of 20-25N, while large dog food requires 6-8mm and a hardness of 30-35N. Therefore, the extruder must support the replacement of different specifications of ring dies and pressure rollers, and the compression ratio of the ring die should be adjustable between 1:4 and 1:10. Twin-screw extruders distribute shear force more evenly, creating a honeycomb structure within the feed pellets for a soft, easily digestible texture. Single-screw extruders, on the other hand, are prone to uneven pellet density and rough surfaces, making them suitable only for low- to mid-range pet food production.

Formula compatibility and hygiene standards are also crucial. Pet food often includes meat, fruits, and vegetables, requiring extruders with good material adaptability. The feeding system should be made of stainless steel with a non-stick coating to prevent meat from sticking and clogging. Furthermore, pet feed extrusion machines must meet food-grade hygiene standards, with the barrel and screw easily disassembled for cleaning to prevent residual materials from contaminating subsequent batches. For companies producing grain-free pet food, it's also essential to ensure the equipment can effectively process starchy ingredients such as potatoes and sweet potatoes to guarantee consistent extrusion results.
