Knotting Treats / Dog Chew Knots – Finished Products

1. Fully Automatic Knotting Treats Line

Our Fully Automatic Knotting Treats Line is an advanced solution for producing high-quality knotted pet chews and dog chew knots. It integrates material preparation, extruding, knot forming, and conveying into a continuous automated process. The line handles rawhide and similar materials, ensuring uniform knotting, strong structure, and attractive appearance of final products.

Compared with traditional manual processing, it greatly improves production efficiency, reduces labor dependency, and ensures stable output quality. Equipped with intelligent control systems and high-precision forming units, the line allows flexible adjustment for different sizes and shapes of dog chew knots.

2. Designed for Pet Treat Manufacturers, Meat Processors, and Export Markets

This production line is purpose-built for:

• Pet treat processing plants producing knotted chews and dog chew knots

• Rawhide processing companies upgrading from manual to automatic knotting

• Functional pet snack manufacturers adding vitamins and probiotics

• Export-oriented food businesses supplying knotted treats to global markets

• Large-scale pet food brands seeking high-efficiency automated production

Its industrial design ensures reliable output, recipe consistency, and long-term operation—key factors for competitive knotted treat production.

3. Production Process Flow

This Knotting Treats Production Line follows a mature, industrial process designed for stable output, consistent product quality, and efficient large-scale production.

Batching → Mixing → Extruding → Cooling → Knot Forming → Traying → Trolley Loading

3.1 Batching & Mixing

Rawhide, meat paste, flour, and functional additives are precisely batched and mixed. Liquid ingredients are added continuously through quantitative pumps for uniform blending.

3.2 Extruding

The mixed material is fed into an extruder which shapes the raw material into continuous strips. The extrusion process ensures uniform density and consistent texture for knot forming.

3.3 Cooling

Extruded strips pass through a cooling conveyor to stabilize their shape and texture. This step ensures the material is ready for precise knot forming.

3.4 Knot Forming

The cooled strips enter the knot treats former. High-precision forming units create uniform knots with strong structure and attractive appearance. The system supports different sizes and shapes.

3.5 Traying & Trolley Loading

Formed knots are automatically placed onto trays. Trays are then loaded onto trolleys automatically. Operators only need to push trolleys into the drying room. Continuous drying solution is also available.
