Tien Giang is Vietnam's largest "fruit kingdom," with an area of over 80,000 hectares, famous for its specialized farming areas producing billion-dollar export specialties: Durian from Cai Lay, Chau Thanh, and Cai Be (over 22,000 hectares), Hoa Loc mango from Cai Be, dragon fruit from Cho Gao, and pineapple from Tan Phuoc.. During peak harvest season, the daily production of ripe durian fruit in the thousands poses a crucial challenge: how to quickly cool the fruit core, prevent cracking and stem rot, and deep-freeze durian segments to meet the standards for official export to China, the US, and the EU.

Rapid cooling cold storage, -40°C deep freezing chamber, and export fruit storage facilities in Tien Giang.. The system implemented by Tan Long helps optimize electricity costs, ensures stable 24/7 operation, and meets fire safety standards according to QCVN 06:2022/BXD.
1. Specific Two-Stage Cold Storage Requirements for Fruit Warehouses in Tien Giang Province
- Fresh durian for export (Cai Lay, Cai Be): After sorting at the warehouse, durian fruits need to be moved to a cold storage facility (pre-cooling) to lower the core temperature of the fruit. +13°C to +15°C Within 4-6 hours, humidity 85% – 90% Combining ethylene gas extraction with fans ensures thorough removal. This keeps the fruit fresh for 25-35 days before export.
- Durian segment freezing chamber with air blast freezer: Chamber temperature maintenance -35°C to -40°C, With forced air speeds of 4-6 m/s, the core of the durian pulp reaches -18°C in just 45-60 minutes. It is then transferred to a freezer storage facility. -18°C to -22°C It can be preserved for 12-24 months and the durian flesh remains rich, creamy, and golden yellow.
- Hoa Loc sand mangoes & Cho Gao dragon fruit: We need a cold storage facility. +8°C to +10°C for mangoes and +4°C to +6°C For dragon fruit, this helps keep the stem green and firm.

7. Frequently Asked Questions (FAQ)
1. Can Ri6 durian and Monthong Cai Lay durian be stored at the same temperature?
Both varieties are suitable for pre-refrigerated temperatures of +13°C to +15°C and humidity of 85% – 90%. However, Monthong may have a longer storage time than Ri6, by about 5-7 days, due to its thicker shell.
2. How long does it take for the Tan Long durian freezing cellar to freeze 1 ton of durian pulp?
In just 45-60 minutes, the durian flesh's structure is guaranteed not to become watery when thawed.
