• 5. Achieved Results
• 6. Frequently Asked Questions (FAQ)

• Context: A rattan and bamboo weaving enterprise in Long Hai required a finished product drying solution for export, meeting strict standards for moisture content, color, and shape.
• Challenge: Long Hai's hot, humid coastal climate with salt mist; rattan and bamboo are prone to warping, cracking, and mold if dried improperly.
• Solution: Installation of 02 DeAir.RE-600H heat-pump dryers (total capacity 1,200 kg/day), operating in a 15-60°C temperature range.
• Result: Evenly dried rattan and bamboo, natural color retention, zero warping, and 50% energy savings compared to traditional electric resistance drying.

⚠️ TECHNICAL RISKS

• Sensitivity to high temperatures: Prone to becoming brittle, cracking, or losing natural color when dried at excessively high temperatures.
• Susceptibility to mold and pests: If moisture is not well-controlled during drying and storage.
• Warping and deformation: Caused by uneven moisture loss across different parts of the product.

✅ EXPORT STANDARDS

• Uniform moisture content: Typically 10-15% after drying (aligned with rattan/bamboo storage standards of 35-50% RH at 16-32°C).
• Natural color retention: No yellowing or fading.
• No warping or cracking: A critical factor for handicraft aesthetics and structural integrity.
• Mold-free: Ensuring both quality and visual appeal.

🔧 STRATEGIC ADVANTAGES

1. Operational flexibility: Can run 1 or 2 units depending on production volume, saving electricity during low-demand periods.
2. System redundancy: If one unit requires maintenance, the other continues operating, preventing production downtime.
3. Even heat distribution: Placing 2 units at strategic locations ensures uniform hot airflow distribution throughout the drying room.
4. Optimized CAPEX: Lower total investment cost compared to a single, high-capacity custom unit.

📊 COMPARISON: TRADITIONAL DRYING VS. DEAIR.RE-600H

• Uniform moisture: Rattan and bamboo reach 10-15% moisture content after drying, with no "dead spots".
• No warping: Product shape and structural integrity are perfectly maintained.
• Natural color retention: No yellowing or fading occurs.
• Mold-free: Ensuring top-tier quality and aesthetics.

Q1: Why use 02 x RE-600H units instead of 1 larger capacity unit?

Using two units offers multiple advantages: (1) Operational flexibility – you can run 1 or 2 units based on daily volume, (2) System redundancy – if one unit needs maintenance, the other keeps production running, (3) Better heat distribution across the drying room, and (4) Lower total capital expenditure compared to a single high-capacity custom unit.

Q2: Can the heat-pump dryer reach the necessary temperature to dry rattan/bamboo without making it brittle or cracked?

Absolutely. The DeAir.RE-600H operates within a 15-60°C range, perfectly matching the ideal drying temperature for rattan and bamboo (typically 45-55°C). Crucially, its precise temperature and humidity control prevents thermal shock, ensuring even drying without brittleness or cracking. If rapid heating is ever needed, the optional 8.4 kW supplementary heater per unit can be activated.

Q3: Does Long Hai's coastal climate affect the machine's performance?

DeAir carefully factors in coastal climates when designing solutions. The DeAir.RE-600H features a corrosion-resistant powder-coated steel casing and well-protected heat exchangers. Furthermore, the 600 kg/day capacity per unit is more than sufficient to handle the high moisture infiltration load from the marine environment, ensuring stable year-round performance.

Q4: Can DeAir program custom drying curves for different types of rattan and bamboo?

Yes! Equipped with an HMI screen and PLC controller, the DeAir dryer can store multiple "drying curves" tailored to different materials (rattan, bamboo, nứa, trúc, etc.), varying thicknesses, and initial moisture levels. Operators simply select the appropriate profile, and the system automatically adjusts temperature, time, and airflow. DeAir's technical team assists in setting up these profiles during the handover process.
