Turnkey Cold Storage for Fresh & Frozen Fruits (CA Technology)

Perfectly preserves freshness, vibrant color, and green stems of Vietnamese tropical fruit. Integrates high-humidity microclimate control (85% to 95% RH), ethylene gas scrubbers preventing premature ripening, and Controlled Atmosphere (CA) technology.

Fresh fruit cold storage is a Controlled Atmosphere (CA) industrial refrigeration facility integrated with rapid pre-cooling rooms. The system maintains optimal temperature bands per tropical cultivar, preventing chilling injury, preserving stem hydration, and complying with strict export phytosanitary barriers in the US, Japan, and the EU.

Technical Engineering Overview: Export Fruit Cold Storage & CA Preservation

Each fresh export fruit variety has unique respiration rates, ethylene production rates, and chilling sensitivities. Tan Long custom-engineers refrigeration rooms for each cultivar, strictly managing temperature bands, gentle laminar airflow, and relative humidity so shipments consistently pass strict export phytosanitary inspections.

1. Optimal Storage Temperatures & Chilling Injury Thresholds for Tropical Fruits

Below is a comprehensive technical matrix detailing target storage temperatures, preservation methodologies, shelf lives, and packaging requirements:8rem 0;">

Product Form / Cut Refrigeration Method Storage Room Temperature Commercial Shelf Life Core Technical Protocol
Fresh Whole Durian Stem pre-cooling & chilling +13°C ÷ +15°C 20 - 30 Days 85-90% RH, gentle laminar airflow preventing thorn cracking
Quick Frozen Durian Pulp Segments -38°C (Rapid Blast Freezing 4h) -18°C ÷ -22°C 18 - 24 Months Vacuum-sealed in PE pouches, retains rich creamy texture upon thawing
Dragon Fruit (White & Red Flesh) Sanitizing wash & forced-air drying +3°C ÷ +5°C 35 - 45 Days 90-95% RH, scales and stems remain hydrated and green without yellowing
Cat Chu & Australian Mangoes VHT Vapor Heat Treatment +10°C ÷ +12°C 25 - 35 Days Strictly maintain above +9°C to prevent chilling injury and peel blackening
Export Cavendish Bananas Active catalytic scrubbing of endogenous ethylene +13°C ÷ +14°C 40 - 50 Days CO2 < 5%, O2 maintained at 2-5% inside CA cold storage

2. Gas-Tight Airtight Enclosure & Catalytic Ethylene Scrubbing Equipment

Harvested fruit continues respiration and produces ethylene gas, accelerating ripening and decay. Tan Long fruit cold storage integrates advanced preservation technologies:

4. Six-Step EPC Turnkey Construction Workflow for Controlled Atmosphere Cold Rooms

  1. Export Variety Survey & Chilling Injury Analysis: Determining precise chilling thresholds for each cultivar (durian, mango, longan, dragon fruit, pomelo).
  2. Aerodynamic Airflow Modeling for Palletized Crates: Engineering aisle spacing and pallet chimney gaps ensuring gentle cool air reaches every center crate evenly.
  3. VFD Refrigeration Packaging & Gas-Tight Doors: Prefabricating inverter switchboards and airtight gas-sealed doors at Tan Long’s Long An factory prior to delivery.
  4. Thermal Envelope Assembly & Pressure Equalization Valves: Erecting PIR panels and two-way pressure release valves preventing structural deflection in airtight CA chambers.
  5. Climate Tuning & 48-Hour Full Load Commissioning: Verifying 90-95% RH without condensation droplet formation and stabilizing temperatures over 48 continuous hours.
  6. Export Certification Handover & Post-Harvest Training: Handing over post-harvest protocol manuals and granting cloud-based smartphone monitoring access to orchard managers.

5. Frequently Asked Questions on Fruit Pre-Cooling & Preservation (FAQs)

Q: What is the typical turnkey construction timeline for an export fruit cold storage facility?

For small to medium facilities (under 50 tons), prefabrication and installation take 15 to 20 business days. For industrial multi-room facilities (100 to 1,000+ tons), total EPC execution typically spans 30 to 45 days including pressure testing and continuous temperature pull-down commissioning. For export logistics packhouses exceeding 200 tons, installation timelines span 20 to 35 business days depending on civil construction readiness.

Q: Does Tan Long provide thermal mapping validation and licensing compliance documentation?

Yes. Tan Long engineers supply complete technical dossiers and multi-point thermal mapping test reports calibrated to Quatest/NIST standards, assisting clients in seamlessly securing HACCP, ISO 22000, and export phytosanitary certifications.

Q: In the event of a power outage or compressor fault, is stored product protected?

Thanks to high-pressure molded PIR panels (125mm to 150mm) with superior thermal resistance, storage chamber temperature rises by less than 1°C per 12 hours during total power outages, providing ample buffer time before backup generator power engages. Simultaneously, the SCADA telemetry system transmits instantaneous emergency alerts to the facility manager and Tan Long’s 24/7 rapid on-call engineering dispatch team.
