Dry Pet Food Production Line

Overview

The Dry Pet Food Production Line is an advanced automatic system for manufacturing dog food, cat food, fish feed, and small animal feed.
It integrates mixing, extrusion, drying, coating, cooling, and packaging into one continuous production process, ensuring consistent product quality, optimal nutrition, and efficient operation.

This line is designed for commercial pet food factories and feed manufacturers seeking high automation, flexible recipes, and compliance with food-grade standards (HACCP / ISO22000 / CE).
All parts in contact with food are made of SUS304 stainless steel, providing durability, hygiene, and ease of cleaning.

Production Flow

1️⃣ 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.

2️⃣ 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.

3️⃣ Cutting & Shaping
The rotating cutter attached to the extruder forms pellets in different shapes — round, bone, heart, or custom molds — depending on customer requirements.

4️⃣ 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.

5️⃣ 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.

6️⃣ Cooling
A vibration cooling conveyor brings product temperature down to ambient levels, ensuring stability before packing.

7️⃣ Weighing & Packaging
Automatic weighing and packaging machines fill and seal the finished dry pet food into bags or pouches, ready for storage and sale.
