In the automated landscape of modern poultry production, the efficiency of the manure removal system is non-negotiable. While polypropylene (PP) belts are common, PVC (Polyvinyl Chloride) manure belts remain the preferred choice for facilities requiring superior flexibility, extreme surface smoothness, and high-load capacity.
For procurement managers and equipment manufacturers (OEMs), the challenge with PVC isn't its performance—it’s its durability. Low-quality PVC belts often suffer from delamination (the PVC layer peeling away from the fabric) and excessive stretching.
At ANNILTE, we have engineered a new generation of PVC manure belts that integrates 17 years of polymer expertise with proprietary HST Technology. We solve the molecular challenges of PVC to deliver a belt that outperforms standard alternatives in every metric.
1. Ending the Delamination Crisis: Co-Polymer Molecular Bonding
The Pain Point: The most frequent failure of PVC belts is delamination. When exposed to the acidic environment of poultry manure, the adhesive bond between the PVC cover and the polyester fabric core often breaks down, causing the belt to peel apart.
The ANNILTE Solution: We utilize Special Drum Vulcanization to create a Co-polymer Molecular Chain that fuses the PVC directly into the fabric lattice.
- Interfacial Strength: Our bonding strength is 30-40% higher than standard industry cold-bonding methods.
- The Result: A unified structure that resists the corrosive effects of ammonia and moisture. Even after years of 24/7 operation, ANNILTE PVC belts maintain their integrity without peeling or bubbling.
2. Dimensional Stability: HST Zero-Stretch Technology
The Pain Point: PVC is naturally more elastic than PP. Under the weight of heavy, wet manure, standard PVC belts are prone to stretching and narrowing. A narrowed belt leads to manure leaking into feed troughs and mechanical jams.
The ANNILTE Solution: Every PVC manure belt undergoes our proprietary HST (Heat Setting Technology) Secondary Setting.
- Tensile Integrity: We stabilize the internal stress of the polyester carcass, achieving a strength of ≥10N/mm² at 1% strain.
- True Feed Control: The belt maintains its exact width and tension for its entire lifespan. This dimensional stability is critical for the precise sensor tracking required in fully automated H-type cage systems.
3. The "High-Toughness Window": Shore A 80-85 Optimization
The Pain Point: Many PVC belts become hard and lose their grip in winter, leading to slippage on the drive rollers. Conversely, in summer heat, they can become too soft and "sticky," increasing friction and motor load.
The ANNILTE Solution: We precisely modulate the PVC formula to stabilize the modulus within the 800-1000 MPa window, maintaining a Shore A hardness of 80-85.
- All-Weather Resilience: This ensures the belt remains flexible and supple at -40°C while resisting surface tackiness at +80°C. It provides the perfect balance of "grip" and "glide" for consistent scraper performance.
4. Extreme Hygiene: Non-Porous Surface Engineering
The Pain Point: Bio-security is the lifeblood of a modern poultry farm. Porous belts can harbor pathogens like Salmonella. Standard PVC often has microscopic surface pits that trap organic waste.
The ANNILTE Solution: We exclusively use 100% Virgin PVC Resin from Fortune 500 chemical partners.
- Micro-Level Smoothness: Our extrusion process creates a non-porous, high-density surface.
- Easy-Clean Advantage: Manure slides off easily, and the surface is resistant to chemical sanitizers. This significantly reduces water usage during cleaning cycles and ensures your facility meets the strictest FDA/EU food safety standards.
5. HST Zero-Tracking: Protecting Your Equipment
The Pain Point: Tracking deviation (running off-center) is the silent killer of belts. A wandering belt rubs against the frame, creating plastic dust and destroying the edges.
The ANNILTE Technical Advantage: By eliminating internal stresses through HST Technology, we ensure our PVC belts have a perfectly uniform density across their entire width.
- Self-Centering Reliability: The belt runs straight and true without constant manual adjustment. This protects your machine's high-value rollers and ensures a clean, dust-free environment for your flock.
