Dry Pet Food Production Line

Dry Pet Food Production Line

Ingredient Mixing
Various raw materials (corn flour, rice flour, meat powder, fish meal, vitamins, and minerals) are automatically weighed and mixed to ensure uniform nutrition distribution.

Extrusion & Cooking
A twin-screw extruder cooks and shapes the pet food under controlled temperature and pressure.
This process enhances digestibility, texture, and product expansion rate — suitable for different animal species and sizes.

Cutting & Shaping
The rotating cutter attached to the extruder forms pellets in different shapes — round, bone, heart, or custom molds — depending on customer requirements.
Drying
The extruded feed is sent into a multi-layer hot-air dryer, which removes excess moisture to extend shelf life and prevent microbial growth.

Oil Spraying & Flavoring
After drying, the products are evenly coated with animal fat, palatability enhancers, or vitamins using an oil spraying drum to improve flavor and nutrition.

Cooling
A vibration cooling conveyor brings product temperature down to ambient levels, ensuring stability before packing.

Weighing & Packaging
Automatic weighing and packaging machines fill and seal the finished dry pet food into bags or pouches, ready for storage and sale.
