Binh Thuan is Vietnam's number one dragon fruit capital, with over 1,000 hectares under cultivation. 33,000 hectares in Ham Thuan Bac, Ham Thuan Nam, Bac Binh, Annual export volume exceeds 700,000 tons. At the same time, with a 192 km long coastline and bustling fishing ports, Phan Thiet, La Gi, Tuy Phong, Phu Quy, The need to preserve white and red-fleshed dragon fruit and freeze offshore-caught seafood requires a chain of industrial cold storage infrastructure that meets international standards.
Tan Long Refrigeration and Electrical Engineering Joint Stock Company We are a leading and reputable EPC general contractor, specializing in design and construction. Cold storage for preserving dragon fruit for export, rapid cooling cold storage, and freezing chambers for seafood in Binh Thuan.. We apply advanced refrigeration technology standards, fire-resistant PIR panels (B1/B2), and energy-saving Inverter compressor systems up to 30%.
1. The Pain of Post-Harvest Damage to Dragon Fruit and Aquatic Products in Binh Thuan
- Fresh dragon fruit for export (Ham Thuan Nam, Bac Binh): Dragon fruit is harvested under the scorching sun of 36°C – 38°C in Binh Thuan. If the temperature is not lowered quickly, the dragon fruit calyxes (fruit scales) will turn yellow, shrivel, the fruit body will lose water and wrinkle, and brown spot mold (Neoscytalidium dimidiatum) will break out, causing a drop in export quality.
- We need a cold storage (pre-cooling) vault: Lower the core temperature of the fruit from 35°C down +8°C to +10°C for 4 hours, then maintain in a cool place. +4°C to +6°C, with humidity of 90% – 95% To keep the green dragon fruit stems firm throughout the 30-40 day journey in refrigerated containers to Europe and the US.
- Fisheries at Phan Thiet and La Gi fishing ports: Squid, prawns, and mackerel require deep freezing in an airtight container. -35°C to -40°C before being placed in the freezer. -22°C to -25°C to prevent cell membrane rupture.

7. Frequently Asked Questions (FAQ)
1. How can dragon fruit stems be kept fresh and green throughout the 40-day export period?
The secret lies in the pre-cooling process (rapid temperature reduction within 4 hours) combined with maintaining humidity at 90% – 95% and controlling convective air velocity to a gentle level below 0.3 m/s to prevent the ears from drying out.
2. In coastal areas of Phan Thiet and La Gi, are the outdoor units susceptible to rust and corrosion?
Tan Long applies a specialized anti-corrosion salt-resistant coating to the aluminum heat sink fins and powder-coated galvanized steel frame, ensuring the equipment's lifespan exceeds 15 years.
