Air Chilling Cooling Shackle KD（with 2 Legs for Poultry Chicken & Broiler Slaughter Processing Line）

1. Product Quick Reference

2. Product Introduction – The KD Compact Solution for High-Density Chilling Lines

The ZYRP-PSSK1009 air chilling shackle KD is a lightweight, 2-leg shackle manufactured from high-strength engineering plastic, purpose-built for air-chilling tunnels, weighing stations, and cut-up lines in broiler, chicken, and poultry processing plants. The KD configuration delivers reliable single-bird suspension with a compact, efficient design optimized for high-density overhead conveyor installations. As a core component within ZYRP's comprehensive spare parts ecosystem, this poultry processing shackle offers processors a durable, corrosion-free alternative that contributes to measurable reductions in energy consumption, maintenance labor, and total cost of ownership.

Also known as an air chill shackle, air chiller shackle, air chilling hook, or poultry air chilling hanger, the ZYRP-PSSK1009 leverages the natural thermal insulation properties of engineering plastic to outperform metal alternatives in cold, wet environments. Unlike stainless steel, the non-conductive plastic body minimizes heat transfer during chilling, while its corrosion-free plastic shackle construction eliminates rust entirely. At approximately 50% lighter than steel equivalents, it reduces conveyor chain tension, drive motor load, and energy consumption. The smooth, non-porous surface ensures full HACCP-compliant CIP hygiene.

3. KD Configuration – Maximizing Line Density Without Compromising Airflow

The KD (2-leg) configuration of the ZYRP-PSSK1009 air chilling shackle KD is specifically engineered for processing lines where space efficiency and per-position throughput are critical operational requirements. Unlike multi-bird shackles that suspend two or more birds per position, the KD single-bird design allows for closer center-to-center spacing on the overhead conveyor rail — typically 150–200mm versus 300–400mm for double-bird configurations. This increased density enables processors to achieve higher throughput within the same chiller tunnel length, reducing capital expenditure on tunnel expansion or enabling higher production volumes from existing infrastructure. The single-bird suspension also ensures that each carcass receives uniform air circulation around its entire surface, eliminating the shading effect that can occur when birds are suspended in close proximity to one another in multi-bird configurations. This uniform airflow promotes consistent chilling rates across all birds, improving product quality and reducing the incidence of under-chilled or over-chilled carcasses. The poultry processing shackle KD design also simplifies loading and unloading operations, as operators handle one bird at a time — a workflow that is particularly advantageous in high-volume facilities where speed and accuracy are paramount.

4. Thermal Insulation – Quantifiable Energy Savings in Chilling Operations

The corrosion-free plastic shackle design of the ZYRP-PSSK1009 delivers superior thermal performance through the natural insulation properties of its engineering plastic material. With a thermal conductivity approximately 200 times lower than stainless steel, the plastic shackle does not conduct heat away from the carcass or transfer heat from the conveyor environment into the product. The ZYRP-PSSK1009 eliminates this heat bridge effect, allowing the air-chilling system to operate at peak efficiency. Field data indicates that switching from steel to plastic shackles in air-chilling tunnels can reduce chilling time by 5–8% and lower energy consumption by 6–10%, depending on tunnel configuration and throughput. For a typical facility operating multiple chilling tunnels, these savings can translate to thousands of dollars in annual energy cost reduction — a compelling return on investment for this broiler slaughter line spare part.

5. Corrosion-Proof Longevity – Reducing Replacement Frequency and TCO

The corrosion-free plastic shackle construction of the ZYRP-PSSK1009 delivers exceptional longevity in the challenging air-chilling environment — one of the most corrosive areas in the poultry processing plant. Continuous high humidity, condensing moisture, chlorine-based sanitizers, and temperature cycling create ideal conditions for metal corrosion. The engineering plastic material is inherently immune to rust, pitting, crevice corrosion, and oxidation, maintaining its surface finish and structural integrity throughout its entire service life. Unlike stainless steel shackles that can develop corrosion-related degradation over time, the ZYRP-PSSK1009 eliminates the need for periodic replacement due to corrosion — reducing annual spare parts expenditure by an estimated 40–60% compared to metal alternatives.

6. Multi-Stage Versatility – One Shackle for Chilling, Weighing, and Cut-Up

The ZYRP-PSSK1009 broiler slaughter line spare part is engineered to perform reliably across multiple processing stations, offering a degree of versatility that reduces the number of shackle SKUs required in facility inventory. In air-chilling tunnels, the shackle's thermal insulation and corrosion resistance ensure consistent performance at 0–4°C. In weighing stations, the lightweight construction minimizes tare weight interference with load cell measurements, improving weighing accuracy and grading consistency. In cut-up and portioning lines, the rigid plastic construction maintains carcass position for automated and manual cutting operations. This multi-stage versatility allows facilities to standardize on a single air chilling shackle KD for the entire post-processing chain — from chilling through weighing to cut-up — eliminating the need for shackle changeovers between stages. For maintenance teams, a single shackle type means consistent inspection criteria, uniform replacement intervals, and simplified training. As a corrosion-free plastic shackle with extended service life, the ZYRP-PSSK1009 further reduces the frequency of replacements, compounding the inventory benefits over time and positioning it as a strategic choice for processors seeking to streamline operations and reduce overhead.

7. Applications – Air-Chilling, Weighing, Grading, and Cut-Up

• Air-Chilling Tunnels & Blast Chillers: Continuous operation in high-humidity, 0–4°C systems with natural thermal insulation for efficient cooling and reduced energy consumption.
• In-Line Weighing & Grading: Lightweight design minimizes tare weight interference for accurate weighing on automated sorting systems positioned after the air-chilling stage.
• Cut-Up & Portioning Lines: Stable carcass holding during automated or manual cut-up and portioning operations following the chilling cycle.
• Cold Storage & Transfer: Corrosion-proof plastic eliminates rust contamination during temporary cold storage suspension and transfer between processing zones.

8. Quality Assurance and Compliance – Certified for Global Markets

Each ZYRP-PSSK1009 CE-certified air chill hook is manufactured under strict quality control aligned with international standards. The engineering plastic material is verified for food-contact compliance under FDA 21 CFR 177.1500, ensuring that the air chilling shackle KD meets the highest safety requirements for indirect food contact. Critical dimensions — including hook opening, rail-engagement geometry, and KD leg spacing — are subject to 100% verification to ensure consistent drop-in compatibility. Random samples from each batch undergo thermal cycle testing (0°C to 4°C), dynamic load testing, and accelerated wear testing to confirm structural integrity and performance consistency under continuous chilling conditions. CE certification confirms conformity with EU safety directives, while RoHS and SGS certifications validate environmental and material safety standards. As a trusted supplier of corrosion-free plastic shackle components, ZYRP provides full batch traceability documentation with each shipment, supporting facility audits and quality assurance programs. With a minimum order quantity of 500 sets and comprehensive customization options — including dimensions, colors, and branding — the ZYRP-PSSK1009 offers poultry processors a reliable, certified, and cost-effective shackle solution for air-chilling and post-chilling operations.
