Poultry Screw Spiral Chiller is a key broiler chicken slaughtering line machine in quail birds duck goose slaughterhouse abattoir and dressing plant.How to produce a high-end king size spiral chicken cooling machine for poultry slaughtering line? Below is the Production Guide for King-Size Poultry Screw Spiral Chiller:

1. Core Design & Technical Parameters of King-Size Poultry Screw Spiral Chiller for Chicken

• Slaughtering Capacity: 8,000–15,000 bph (birds per hour)

• Cooling Target: Reduce chicken carcass temperature from 40–42°C to 4°C within 40–60 minutes

• Structure: Multi-layer spiral screw conveyor + closed water circulation cooling system

• Material: Full SUS304 stainless steel (thickness ≥ 2.5mm for main body, ≥ 3.0mm for screw shaft/blades)

• Dimensions: Length 12–18m, Diameter 2.2–2.8m, Height 3.5–4.5m (customizable per workshop)

• Cooling Medium: Chilled water (0–2°C) + food-grade chlorine dioxide (50–80ppm) for disinfection

2. Key Components & Manufacturing of king size spiral chicken cooling machine

2.1 Screw chiller Conveyor System (Core Cooling & Conveying Part)

• Screw Shaft: Seamless SUS304 steel pipe (φ159–219mm), CNC machining for concentricity (tolerance ≤ 0.5mm)

• Screw Blades: Cold-rolled SUS304 steel (pitch 300–400mm), welded to shaft with continuous argon arc welding, polished to Ra ≤ 0.8μm

• Support System: Stainless steel bearings (food-grade, waterproof) + reducer motor (11–18.5kW, variable frequency 0–5r/min)

2.2 Spiral Chiller Tank & Insulation

• Poultry Screw Chiller Tank Body: SUS304 stainless steel welded structure, with water inlet/outlet, overflow, and sewage outlets

• Insulation: 50–80mm polyurethane foam + outer SUS304 cladding (heat loss ≤ 5%)

• Water Distribution System: Uniform spray pipes + bottom turbulence nozzles to ensure full carcass immersion

2.3 Chicken Spiral Cooling Refrigeration & Water Circulation System

• Chicken Chiller Unit: Industrial water chiller (cooling capacity 80–120kW, 0–2°C chilled water output)

• Circulation Pump: Stainless steel centrifugal pump (flow 25–40m³/h, head 15–20m)

• Filtration System: 3-stage filtration (stainless steel mesh 1mm + bag filter + precision filter) to remove impurities

2.4 Control & Sanitation System for Spiral Chiller Water Cooled for Chicken

• Control Panel: PLC + touch screen (adjust speed, water temperature, flow; fault alarm)

• CIP System: Automatic cleaning pipeline + high-pressure spray nozzles (cleaning pressure 0.6–0.8MPa)

• Safety Devices: Emergency stop, overload protection, anti-jamming sensor for carcass blockage

3. Production Process Flow of Poultry Spin Chiller

1. Material Cutting & Forming: Laser cutting SUS304 steel plates/pipes; cold rolling screw blades

2. Welding & Polishing: Argon arc welding for tank body/shaft; mechanical + electrolytic polishing (no burrs)

3. Component Assembly: Install screw conveyor, bearings, motor, and water pipes; debug concentricity

4. Refrigeration System Installation: Connect chiller, pump, and filtration; pressure test (1.2× working pressure)

5. Electrical Control Wiring: PLC programming, sensor installation, and circuit debugging

6. Overall assembly & Leak Test: Assemble tank, insulation, and conveyor; water pressure test (no leakage for 24h)

7. Pre-Commissioning: No-load test (4h), load test (8h with 80% capacity), check temperature uniformity

8. Surface Treatment & Packaging: Final polishing, passivation; film wrap + wooden box packaging

4. Spiral Precooler Quality Control & Compliance 

• Material Compliance: SUS304 stainless steel with food-grade certification (GB 9684, FDA 21CFR)

• Welding Standard: Full penetration welding, no porosity/cracks; welds pass X-ray inspection

• Cooling Effect: Temperature uniformity ≤ ±1°C; carcass core temperature reaches 4°C within specified time

• Sanitation: No dead corners; CIP cleaning efficiency ≥ 99.9%

• Certifications: CE, ISO 9001, ISO 22000 (meets EU/US poultry processing standards)

5. Installation & Commissioning Notes of Screw Chiller for Chicken Slaughterhouse

• Foundation: Reinforced concrete foundation (load-bearing ≥ 5t/m²), levelness ≤ 2mm/m

• Piping: Insulate chilled water pipes; install check valves and flow meters

• Electrical: 380V/50Hz power supply, independent leakage protection, grounding resistance ≤ 4Ω

• Debugging: Adjust screw speed and water flow to match slaughter line speed; optimize cooling time

6. Maintenance & Operation Tips for Screw Chiller for Poultry Processing Dressing Plant

• Daily: Clean tank/filter, check water temperature and chlorine concentration in slaughterhouse plant

• Weekly: Lubricate bearings, inspect screw blade wear, calibrate temperature sensors in broiler dressing plant

• Monthly: Check refrigeration unit refrigerant level, clean CIP nozzles in poultry slaughterhouse

• Yearly: Full equipment overhaul, replace worn parts, re-polish key components in chicken abattoir
