Qiaqia Foods 49,500m³ Cold Storage Project for Nut Processing and Raw Food Preservation in China

Project Overview: Precision Storage for Nut & Snack Processing

Project Scope: Design, construction, and commissioning of a large-scale, multi-zone cold storage facility totaling 49,500 cubic meters (m³) for food raw material processing and storage.

Application: Dedicated storage for nuts, dried fruits, and semi-finished products requiring precise temperature and humidity control.

Project Phases & Key Specifications

Phase I (Completed July 2018):

Volume: 19,500 m³

Facilities: Automated Constant Temperature Cold Rooms, Fresh-Keeping Cold Rooms.

Phase II(Completed March 2020):

Automated Controlled Atmosphere Fresh-Keeping Cold Room:

• Volume: 12,500 m³
• Temperature Range: Adjustable 0°C to 10°C
• Humidity: ≤ 50% RH (Independent Dehumidification)
• Primary Use: Storage of nuts and dried fruits.

Refrigerated Storage:

• Volume: 8,750 m³
• Temperature: 0°C to 5°C
• Humidity: ≤ 50% RH (Independent Dehumidification)

Constant Temperature Storage:

• Volume: 8,750 m³
• Temperature: 5°C to 15°C
• Humidity: ≤ 50% RH (Independent Dehumidification)

Critical Performance:

• Cooldown Time: Achieves target temperature throughout the entire warehouse within 3 hours.
• Temperature Uniformity: Ensured consistent temperature distribution across all storage zones.

Advanced Engineering & Technology

Structure: Pentagonal (5-sided) design. All systems (Phase I & II) are independent, allowing for separate operation and control.

Insulation:

• Walls & Ceiling: 100mm thick Polyurethane (PU) Sandwich Panels with double-sided color steel sheets, rated B1 Fire Resistance (Chinese Standard, equivalent to high fire retardancy).
• Floor: 200mm thick High Compressive Strength XPS (Extruded Polystyrene) Insulation.

Refrigeration System:

• Compressors: Internationally renowned, energy-efficient, low-noise, eco-friendly brands (Panasonic, Sanyo) chosen for reliability and low maintenance costs.
• Refrigerant: Environmentally friendly R404A.
• Valves & Components: Premium Danfoss (Denmark) brand valves and components.
• Air Coolers (Evaporators): High-performance units from KaBeO and Jiesheng.

Control & Monitoring System:

• PLC Central Control System: Provides fully automated temperature and humidity regulation.
• Independent Control: Separate and independent operation for temperature and humidity control systems.
• Data Logging & Display: Real-time temperature and humidity display with automatic data storage and recording.
• Alarms & Remote Monitoring: Features include accidental door closure alarm and remote monitoring capabilities.
