Gia Lai is a leading high-tech agricultural center in the Northern Central Highlands, with over 30,000 hectares dedicated to fruit cultivation, and is the number one passion fruit capital in the country. Mang Yang, Dak Doa, Chu Pah, a region of South American Cavendish banana plantations exporting thousands of hectares, and large durian farms exporting fruit in Chu Prong, Ia Grai, Pleiku City. Given the unique characteristics of the plateau terrain with abundant sunshine and air, and the high respiration rate of agricultural products after harvesting, a high-tech cold storage system is a crucial link in maintaining the export rate of Grade 1 products to the Chinese, Japanese, and EU markets.
Tan Long Refrigeration and Electrical Engineering Joint Stock Company We are a reputable EPC general contractor specializing in design consulting and construction. Cold storage for fresh fruit, deep freezing cellars for passion fruit juice, and cold storage for durian in Gia Lai.. We apply modern two-stage refrigeration technology, B1/B2 fire-retardant PIR panels, and a 24/7 SCADA monitoring system to optimize operating costs.
1. The Intensive Cold Requirements of 3 Pointed-Tip Fruit Trees in Gia Lai
- Fresh passion fruit & Passion fruit juice (Mang Yang, Dak Doa): Fresh passion fruit for export requires cold storage. +5°C to +8°C, with humidity of 85% – 90% To keep the peel firm and prevent it from shrinking, for passion fruit puree, the factory needs a deep-freeze freezer. -35°C to -40°C To freeze the fluid mass within 2-3 hours before placing it in cold storage. -18°C.
- South American Cavendish bananas for export: After being packed into cardboard boxes, bananas should be immediately transferred to a cold storage facility to lower the core temperature of the bunch. +13°C to +14°C The humidity was maintained for 6 hours. 90% – 95% Combine this with thorough ethylene gas extraction using a fan. Absolutely do not lower the temperature below 12°C as this will cause chilling injury, turning the banana peel a lead gray color.
- Fresh durian & Frozen durian segments (Chu Prong, Ia Grai): Durian is harvested in abundance from July to September, requiring cold storage to lower the core temperature of the fruit and blast freezers for durian segments intended for export.

7. Frequently Asked Questions (FAQ)
1. Is it possible to store bananas and passion fruit together in the same cold storage facility?
Passion fruit should not be stored together because it releases a strong amount of ethylene gas, causing bananas to ripen prematurely and brown their peels. The two compartments should be separated by partition panels with independent exhaust fans.
2. If passion fruit juice is frozen at -35°C, will it retain its original aroma when thawed?
Thanks to the extremely rapid freezing speed in Tan Long's deep-freezing chamber, the ultra-fine ice crystals do not break the aromatic oil sacs and vitamin C, preserving the characteristic sweet and sour flavor of passion fruit from the Central Highlands.
