Fully Automatic Knotting Line
What is a Fully Automatic Knotting Line ?
A Fully Automatic Knotting Line is an advanced production system designed to manufacture knotted pet treats with minimal labor. Developed by Darin Machinery, it automates the entire process from raw material preparation to tray and trolley loading.
The line automatically completes raw material batching, mixing, extruding, knot treat forming, tray loading, and trolley loading. Operators only need to move the loaded trolleys into the drying room. This greatly reduces labor costs and improves production efficiency.
Every step is controlled by an intelligent automation system. This ensures stable production, consistent knot quality, and high hygiene standards.
For higher capacity, the knot forming machine can also be connected to a continuous drying system. This creates a fully automated production flow with no manual handling between forming and drying.
The Fully Automatic Knotting Line helps pet treat manufacturers increase output, reduce labor dependency, and produce premium-quality knotted chews with maximum efficiency.
Application:
Used for knotting treats Production.

Tray preparation
Placing knots onto trays
Loading trays onto trolleys
Operator action
Step 1 – Raw material batching & mixing
Ingredients are automatically measured and mixed according to the recipe.Step 2 – Extruding
The mixed material is fed into the extruder, which shapes it into continuous strands.Step 3 – Cooling
The extruded strands pass through a cooling conveyor to stabilize texture and temperature.Step 4 – Knot forming
The cooled strands enter the knot treats former, where they are cut and tied into uniform knots.Step 5 – Tray preparation
The traying system supplies empty trays to the loading position.Step 6 – Placing knots onto trays
The knots-putting-onto-trays system automatically arranges finished knots onto each tray.Step 7 – Loading trays onto trolleys
The trays-putting-into-trolley system stacks loaded trays onto trolleys/carts.Step 8 – Operator action
Operators simply push the loaded trolleys into the drying room.
(Optional: A continuous drying solution can be directly connected to the knot forming machine.)

FAQs
Frequently Asked Questions
When purchasing the Fully Automatic Knotting Line, you might be interested in the following questions.
The Fully Automatic Pet Treats Knotting Line from Darin Machinery is designed for efficient and large-scale production of knotted pet treats. Its production capacity typically falls within the following ranges:
Per Hour: Approximately 1,200–3,600 pcs/hour (depending on model)
Per Day: Around 9,600–28,800 pcs/day (based on an 8-hour working shift)
Key Variables That Affect Output:
Product Size & Knot Type: Smaller knots or simpler knot patterns yield higher hourly throughput.
Recipe & Ingredients: Moisture content and type of raw material (meat, starch, etc.) influence extrusion and forming speed.
Automation Level: Fully automatic systems (auto tray loading, trolley stacking) improve efficiency compared to semi-automatic setups.
Operator Skill & Line Setup: Well-trained operators and optimized line configuration can maximize daily output.
If you're aiming for a custom throughput (e.g., higher daily capacity), Darin Machinery can customize the line with multiple lanes or higher-speed knot formers.
Would you like a detailed layout or quote based on your target capacity?
The Fully Automatic Pet Treats Knotting Line by Darin Machinery is engineered to handle a flexible range of knot sizes to accommodate various market needs for pet treats. Here are the typical specifications:
✅ Minimum Knot Size:
Length: ~30 mm
Diameter/Thickness: ~8 mm
This size is usually suitable for small dog treats or cat treats, where portion control and easy chewing are key.
✅ Maximum Knot Size:
Length: ~100 mm
Diameter/Thickness: ~25 mm
This upper range supports larger pet treats, ideal for medium to large dogs, offering longer chewing time and more complex visual appeal.
⚙️ Notes on Customization:
The system can be customized to produce knots beyond these dimensions depending on customer requirements.
The knot former mold and extrusion die must align with the chosen knot size.
For non-standard shapes or multi-color knots, Darin can also fine-tune the forming and cutting components.
Would you like recommendations based on your target market (e.g., toy breeds vs. large breeds)?
Yes, the Fully Automatic Pet Treats Knotting Line by Darin Machinery can be adapted to produce knotted treats with different formulations or colors in a single knot – offering similar multi-variety capability for pet treat applications.
✅ How It Works:
Multi-Extrusion System:
The line can be equipped with multiple hoppers or barrels, each designated for a different formula, color, or flavor (e.g., chicken, beef, pumpkin, or functional additives).
Synchronized Dosing Control:
Each extruder is precisely synchronized to deposit alternating layers, stripes, or segments of different materials before the knotting process.
The result is a visually appealing knot with 2–3 colors or flavors (e.g., chicken–beef–pumpkin combined in one knot).
Automatic Knot Forming & Transfer:
The combined strands enter the knot treats former, where they are cut and tied into uniform knots with consistent multi-color/multi-flavor distribution.
Customizable Segment Ratios & Shapes:
You can configure the ratio of each material within the knot (e.g., 40% chicken / 30% beef / 30% pumpkin).
Different knot shapes (round, bone-shaped, twisted, etc.) can also be achieved via mold changes.
🛠 Optional Features:
Color-Coding per Formula (for visual appeal and variety pack presentation)
Flavor Swirl or Marble Effect (via nozzle modification)
Cooling Conveyor for better shape retention before knotting
Would you like a video demo or a sample knot diagram to visualize the multi-formulation configuration?
The Fully Automatic Pet Treats Knotting Line from Darin Machinery is designed with broad ingredient compatibility, especially tailored for the pet food industry. It can process a wide range of meats, vegetables, and functional additives, thanks to its high-torque extrusion system and precision knot-forming technology.
🥩 Compatible Meats:
All meats must be ground into a fine paste or emulsion for proper extrusion.
Chicken – Lean, cost-effective, widely used in pet treats
Beef – Rich protein source, often used in premium recipes
Duck – High in iron and more digestible for sensitive pets
Lamb – Ideal for hypoallergenic formulas
Fish (e.g., salmon, tuna) – For omega-3 enrichment
Turkey – Lean protein with mild flavor
Pork – Used in some regional formulas
Organ meats (e.g., liver, heart) – Nutrient-dense for natural pet snacks
🥕 Compatible Vegetables & Plant-Based Ingredients:
These are typically steamed or blanched and then mashed or pureed.
Pumpkin – High fiber, great for digestion
Sweet Potato – Rich in beta-carotene, soft texture
Peas – Protein & fiber source
Spinach – Vitamin-rich, used in small proportions
Carrot – Adds color, flavor, and vitamins
Green beans – For added texture and color
Broccoli – High in antioxidants
Corn or Rice Paste – As starch binders or fillers
⚙️ Key Requirements for Ingredients:
Moisture content: Optimal around 25–30% for extrusion stability
Grinding size: Typically 1–3 mm particle size
Binder inclusion: May include gelatin, glycerin, starch to improve extrusion form and knot integrity
