Drying Binh Dinh Rice Paper in the Rainy Season: Daxwell DX-300D Solution Ensures Productivity for Exports

Drying Binh Dinh Rice Paper in the Rainy Season: Daxwell DX-300D Solution Ensures Productivity and Export Quality

Binh Dinh rice paper has long been a famous brand throughout Vietnam and is on its way to conquering international markets. However, traditional craft villages and production facilities have always faced a major challenge known as the "rainy season." The manual sun-drying process comes to a complete halt for months, severely affecting productivity, delivery schedules, and revenue.

To definitively solve this "worry" and enable year-round production, a large-scale rice paper exporter in Binh Dinh approached DeAir to implement a modern, high-tech drying solution.

Technical Challenges of Drying Rice Paper for Export

Drying rice paper is not just about removing moisture. To achieve export quality, the drying process must overcome several complex technical challenges that sun-drying or conventional drying solutions can hardly meet:

• Thinness and Structure: Rice paper is very thin; excessive heat or strong airflow can cause it to warp, crack, or break, reducing the yield of finished products.
• Crispness and Pliability: A perfect balance is required. Drying too quickly makes the paper brittle and prone to shattering, while insufficient drying makes it limp and chewy. Precise control over the final moisture content is crucial.
• Product Color: High-quality rice paper must have the natural translucent white color of rice flour. Inappropriate drying temperatures can cause it to turn yellow, affecting its visual appeal.
• Food Safety and Hygiene: Sun-drying exposes the rice paper to dust and insects, failing to meet the hygiene standards for export.
• Passive Production: The long rainy season makes drying impossible, leading to an inability to fulfill orders and a loss of credibility with partners.

The challenge was to find a technological solution that could simultaneously control temperature, humidity, and time to allow for continuous production, regardless of the weather, while still ensuring the high quality and perfect texture of the rice paper.

DeAir & The Comprehensive Drying Solution with Daxwell DX-300D

Recognizing that the client's core problems were production downtime and difficulty in quality control, DeAir consulted and installed a drying room system using the Daxwell DX-300D Heat-Pump Dryer. This is not just a conventional dehumidifier, but a specialized drying system designed to precisely address the challenges mentioned above.

Technical Specifications of the Daxwell DX-300D Dryer:

• Heating Capacity: 56,980 Btu/h
• Power Consumption: 4.75 kW
• Operating Temperature: 40-60°C
• Airflow: 3,000 m³/h

Why is this solution so remarkably effective?

1. Year-Round Production, No More Rainy Season Worries: This is the greatest benefit, allowing the business to have full control over its production schedule and confidently accept and fulfill large contracts at any time of the year.
2. Low-Temperature Drying Protects the Product: The operating range of the Daxwell DX-300D is ideal for the 38-40°C drying temperature. This low heat gently mimics the natural sun-drying process, helping the paper dry evenly without becoming brittle or warped, maintaining the necessary pliability.
3. Absolute Quality Consistency: Unlike a dehumidifier that can only reduce humidity, the Daxwell heat pump dryer with its intelligent PLC controller allows for precise control of both temperature and humidity in the drying chamber. This ensures every batch of rice paper is dried under the same standard conditions within 3-4 hours, resulting in a product of uniform quality.
4. Hygiene and Energy Savings: Drying in a sealed room completely isolates the rice paper from environmental contaminants. The heat pump's heat recovery technology provides outstanding energy savings, significantly reducing production costs.

The Result: Crispy, Pliable Binh Dinh Rice Paper, Ready for Export Regardless of the Weather

With DeAir's solution, the rice paper production facility in Binh Dinh has solved the biggest obstacle to its growth. Now, they can not only ensure productivity during the rainy season but also enhance their product quality and brand reputation in the international market.

The success of the Binh Dinh rice paper drying project is a testament to DeAir's continuous effort to provide practical technological solutions that help Vietnamese businesses and craft villages overcome challenges, develop sustainably, and reach a global scale.
