Puffed dog food machine
The Datong pet feed extrusion production line is fully equipped with mature technology and a high degree of automation. From raw material mixing to finished product packaging, the entire process is integrated, significantly saving labor and improving production efficiency. The equipment is equipped with a variable frequency control system, ensuring stable operation, precise speed adjustment, and safe and convenient operation. It is paired with multiple types of ovens, offering a wide temperature control range and uniform drying, effectively extending the shelf life of the feed. The dedicated spraying and seasoning system can evenly spray oil and sprinkle seasoning, optimizing the appearance and palatability of the feed. The production line comes in multiple specifications with a wide capacity range, suitable for both small and large manufacturers. It can produce various specifications of pellet feed with neat appearance and stable quality, making it ideal for large-scale production of various types of pet feed.
I. Puffed dog food machine process flow:
Raw material grinding → Raw material mixing (corn flour, soybean meal, starch, fish meal, etc.) → Mixer → Conveyor → Twin-screw feed extruder → Conveying → Drying equipment (electric oven, gas/oil oven or steam oven) → Oil spraying → Twin-drum seasoning system → Cooling conveyor → Screening → Storage bin → Packaging machine
II. Dog food machine processing equipment configuration:
Powder mixer → Feeder → Extruder → Conveyor → Multi-layer oven → Seasoning line → Cooling conveyor → Vibrating screen → Packaging machine

4. Process composition of the pet feed production line:
▶ Mixer: Fully mix raw materials such as corn flour, rice flour, soybean flour, fish meal, meat meal, grain flour, and additives with a certain proportion of water to achieve uniform blending.
▶ Conveyor: Using a motor-driven screw conveyor, transport the mixed raw materials to the feed hopper of the twin-screw extruder. This equipment enables convenient and fast material transfer, saves labor, and offers high efficiency.
▶ Twin-screw feed extruder: Under high temperature and high pressure conditions and the extrusion of the twin screws, the starch structure in the raw materials changes, becoming easily absorbable nutrients. The material is extruded through a feed die, and by adjusting the rotation speed of the rotary cutter, feed pellets of uniform size and length are produced. The specific pellet size and shape can be obtained by changing the die. The feed extruder adopts variable frequency speed control technology, which is energy-saving and provides precise speed control. During motor operation, the current and speed can be directly viewed on the inverter panel, ensuring equipment safety.
▶ Conveyor: Transports the produced feed pellets into the multi-layer drying equipment.
▶ Multi-layer Oven: The oven is divided into electric ovens, fuel oil ovens, gas ovens, and steam ovens. The temperature can be adjusted between 0-150 degrees Celsius via the control cabinet. The interior of the oven features a stainless steel mesh belt, ensuring smooth transportation and low failure rates. Feed pellets circulate through multi-layer S-shaped tracks, drying them to a safe moisture content and extending their shelf life.
▶ Spray Seasoning Line: The oil sprayer applies oils, attractants, etc. The seasoning drum comes in octagonal, cylindrical, single-drum lifting, and double-drum seasoning line configurations, selected based on production volume and product characteristics. It sprays oil onto the surface of the feed pellets while evenly distributing minced meat and spices. This process also removes burrs and rough edges from the pellet surface, making it smoother.
▶ Cooling Conveyor: Reduces the surface temperature of dried feed pellets, promotes fat solidification, lowers pellet temperature, and facilitates packaging.
▶ Vibrating Screen: Screens out excess scattered material and pellet debris.
▶ Packaging Machine: Can use manual sealing machines or automatic packaging machines. For details, please contact the manufacturer.
