Binh Phuoc is known as the "cashew capital" of the country, with its production accounting for over 50% of the national total, concentrated in... Dong Xoai, Chon Thanh, Phu Rieng, Dong Phu. In addition, the fertile red basalt soil at Bu Dang, Bu Gia Map, Loc Ninh Tens of thousands of hectares are being converted to high-quality durian cultivation for export. To prevent white cashew kernels from becoming rancid and turning dull yellow, and to ensure durian retains its flavor for official export to China and the EU, investing in a sophisticated cold storage system with controlled temperature and humidity is a vital requirement for processing plants.
Tan Long Refrigeration and Electrical Engineering Joint Stock Company We are a leading EPC general contractor specializing in mechanical, electrical, and HVAC consulting, design, and construction. Cold storage for cashew kernels, cool storage for fresh durian, and deep-freeze tunnels in Binh Phuoc.. With its comprehensive EPC (Engineering, Procurement, and Construction) contracting capabilities, Tan Long commits to providing genuine equipment, ensuring energy efficiency, and optimizing investment costs.

1. Technical Requirements for Preserving Cashew Nuts and Durian in Binh Phuoc
The two main agricultural export products of Binh Phuoc have completely different preservation requirements:
- For cashew kernels for export (W240, W320, broken in half): Cashew nuts contain a very high amount of unsaturated fat (over 451 TP3T). In the typical hot and humid environment of Binh Phuoc (temperature 32°C – 36°C, humidity > 801 TP3T), the oil in cashew kernels oxidizes rapidly, leading to rancidity, discoloration to dark yellow, and the growth of Aflatoxin mold/insects. Cashew nut storage needs to maintain a controlled temperature. +12°C to +16°C and strictly controlled humidity under 60%.
- For fresh durian and frozen durian segments (Bu Dang, Bu Gia Map): The durian harvest in Binh Phuoc province is in full swing from May to August. Fresh durian requires cold storage to lower the fruit's core temperature. +13°C to +15°C, The humidity should be 85% - 90% to keep the stem fresh and green. Durian segments for export require forced-air freezing. -35°C to -40°C within 45-60 minutes before transferring to freezer storage. -18°C to -22°C.
💡 Tan Long's exclusive technology solution for cashew nuts in Binh Phuoc:
Integration Industrial dehumidifier with rotor dehumidifier and cooling coil. This helps maintain the humidity in the storage chamber at a constant level of $50% – 55%$, completely preventing condensation in the vacuum packaging and keeping cashews crispy and fragrant for 18-24 months.

7. Frequently Asked Questions (FAQ) About Cold Storage in Binh Phuoc
1. What is the most important factor to consider when preserving cashew kernels?
Humidity is a crucial factor. If you only lower the temperature without controlling the humidity, the cashews will absorb moisture and become soggy and moldy. Tan Long always equips its warehouses with dehumidifiers combined with microprocessor sensors to control humidity below 55%.
2. Does Tan Long's PIR panel warehouse shell meet fire safety acceptance standards in Binh Phuoc?
Yes. Tan Long PIR panels meet fire resistance standards B1/B2 according to QCVN 06:2022/BXD, have a burn test certificate from the Institute of Building Science and Technology (IBST), and fully meet the fire safety acceptance requirements at Becamex Binh Phuoc Industrial Park.
