In the global pet treat manufacturing sector, rawhide products—such as rawhide rolls, rawhide twists, rawhide sticks, and rawhide twists/rolls treats—remain timeless bestsellers thanks to their durability and dental care benefits. However, for decades, rawhide treat manufacturers have struggled with traditional production bottlenecks: heavy reliance on manual labor for twisting, weather-dependent open-air drying, low throughput, and inconsistent product quality.
As a pioneer in automated processing machinery, Darin introduces the Complete Automatic Rawhide Twisting & Rolling Solution. Designed to eliminate manual production constraints and weather reliance, this end-to-end processing line provides global pet treat manufacturers with a modern, highly automated production engine.
I. Eliminating Weather Dependency and High Labor Costs: Traditional Processing vs. Darin Fully Automatic Line
| Comparison Dimension | Traditional Rawhide Processing | Darin Fully Automatic Processing Line Solution |
|---|---|---|
| Labor Dependency | Requires dozens of manual twisting work | Requires only 1–2 operators on-site to monitor the entire line |
| Drying Cycle | Outdoor rack drying; susceptible to weather conditions, contamination, and insects | Continuous multi-layer drying system with precise temperature control and year-round operation |
| Quality & Consistency | Variable manual twisting tightness; uneven hand-cutting lengths | Visual cutting system and automated twisting/rolling ensure uniform specs |
| Capacity & Scalability | Low output; difficult to fulfill large-scale OEM/ODM overseas orders | High capacity of 600 long twists/rolls per hour (1.2m long); 4,800 units per 8-hour shift |
II. Core Engineering: Process Flow and Precision Positioning of Darin’s Automated Line
The Darin automated processing line seamlessly integrates raw material characteristics with modern control automation. From raw wet rawhide to packaged final products, the system executes 10 continuous processing steps:
- Squeezing: Removes excess water from wet rawhide to standardize moisture levels.
- Squeezing: Removes excess water from wet rawhide to standardize moisture levels.
- Stripping: Precision-slits wet rawhide into uniform strips.
- Visual Cutting System: Uses intelligent vision sensors to locate optimal cutting positions, maximizing raw material utilization.
- Automated Twisting & Rolling System: Fully automatically twists or rolls rawhide strips into dense, uniform rawhide twists or rawhide rolls.
- Continuous Automated Drying: A 20-meter long, 17-layer spring clamp conveyor dryer provides controlled heat (40–100°C), eliminating outdoor sun-drying.
- Cooling: Rapid cooling stabilizes product geometry and texture.
- Precision Cutting: Cuts the 1.2-meter rawhide sticks into exact target customer lengths.
- Sorting, Counting/Weighing, & Primary Packing: Automated sorting and primary pouch packaging.
- Cartoning & Palletizing: Automated case packing and pallet loading.
- Transparent Film Wrapping: Complete stretch wrapping for palletized shipments.
