1.2. Challenges in Product Preservation
⚠️ ISSUES TO RESOLVE
High Humidity: Northern Vietnam's climate frequently exceeds 80% RH, causing mold, shrinkage, and product deformation.
Traditional Drying Methods: Sun-drying is weather-dependent and yields inconsistent quality.
Export Requirements: Precise humidity control is mandatory to meet international standards.
Operating Costs: A need for energy-efficient solutions to optimize production costs.
Precise Humidity Control: Maintains 40-50% RH, the ideal range for preserving rattan and bamboo.
Mold Prevention: Completely eliminates the conditions required for mold growth.
Natural Color Retention: Stable drying temperatures preserve the natural color of the materials.
Cost Efficiency: Reduces electricity consumption by 40-50% compared to traditional resistance drying.
Stable Operation: Capable of 24/7 operation, independent of weather conditions.
3. Professional Handover and Installation Process

7. Frequently Asked Questions (FAQ)
Q1: What types of products can the DeAir.RE-600H dry?
It is highly versatile and can dry rattan/bamboo, textiles, agricultural products (rice, corn, coffee, pepper), food items (dried fruits, snacks), pharmaceuticals (herbs), and seafood (fish, shrimp, squid). The programmable drying cycles can be customized for each specific product type.
Q2: How long does it take to dry rattan and bamboo?
Typically, it takes 12-24 hours, depending on the initial moisture content and the thickness of the products. Compared to natural sun-drying (3-5 days), this significantly shortens the cycle and boosts production capacity.
Q3: Is the electricity cost for operating the machine high?
No. Thanks to heat-pump technology, it saves 40-50% on electricity compared to traditional resistance dryers. With a power consumption of 9.2 kW, the operating cost is highly reasonable, and the ROI is typically achieved within 12-18 months.
